    Nuclear fission energy can deliver safe, sustainable, competitive and practically carbon-free energy to Europe's citizens and industries. Within the framework of the Strategic Energy Technology Plan (SET Plan), the European Commission's stakeholders in this field have formulated a collective vision of the contributions this energy could make towards Europe's transition to a low-carbon energy mix by 2050, with the aim of integrating and expanding R and D capabilities in order to further this objective. The groundwork has been prepared by the stakeholders listed in Annex II, within the framework of two EURATOM FP6 (Sixth Framework Programme) Coordination Actions, namely SNF-TP (Sustainable Nuclear Fission Technology Platform) and PATEROS (Partitioning and Transmutation European Road-map for Sustainable Nuclear Energy), with contributions from Europe's technical safety organisations. This vision report prepares the launch of the European Technology Platform on Sustainable Nuclear Energy (SNE-TP). It proposes a vision for the short-, medium- and long-term development of nuclear fission energy technologies, with the aim of achieving a sustainable production of nuclear energy, a significant progress in economic performance, and a continuous improvement of safety levels as well as resistance to proliferation. In particular, this document proposes road-maps for the development and deployment of potentially sustainable nuclear technologies, as well as actions to harmonize Europe's training and education, whilst renewing its research infrastructures. Public acceptance is also an important issue for the development of nuclear energy. Therefore, research in the fields of nuclear installation safety, protection of workers and populations against radiation, management of all types of waste, and governance methodologies with public participation will be promoted. The proposed road-maps provide the backbone for a strategic research agenda (SRA) to maintain Europe's leadership in

    Today, the analysis of renewable energy places the emphasis on the technological and economic attributes with social and environmental impact assessment providing for a rather static, narrow frame of analysis. The participation and response of social actors and other stakeholders is usually of a traditional type, with consultation documents and public meetings, collection of complaints and suggestion schemes. This often encourages parochialism and an over-concentration on relatively trivial issues. It is, therefore, imperative to establish a new participatory planning platform to incorporate the wider socio-economic aspects of renewable energy systems and to provide for an operational analytical decomposition of them. In this work the issue of decomposition analysis is clarified, and a new agenda for the societal and technological decomposition analysis of renewable energy systems is developed. A case study is disclosed to present the relevance of the established platform for integrated (renewable) energy systems planning. Innovative aspects comprise of the simultaneous inclusion of decision analysis and social acceptance methods and tools in concert with the related public participation techniques. (author)

The report puts forth a version of the short-term, medium-term and long-term development of nuclear fission technologies, whose goal it is to achieve sustainable nuclear power generation, significant improvement of its economic indices, and continuous safety improvement, and to prevent it from abuse. The document includes proposals for timescales and milestones of the development and deployment of potentially sustainable nuclear technologies and provisions for a harmonization of educational and training activities in all EU Member States and for innovation of their research infrastructures. For the development of nuclear it is vital that it gains public acceptance. Therefore it is necessary to support research in the safety of nuclear facilities, staff and public protection from ionizing radiation, handling of all kinds of nuclear waste, and inspection methods involving the public. The time plans proposed will form the backbone of the Strategic Research Agenda (SRA), which should help Europe keep its leadership position in nuclear power, both in the research domain and in the industrial domain. The report emphasizes that nuclear will hold a key position among European energy sources, and calls upon European countries to make all efforts to meet the vision for a sustainable nuclear energy in line with European Commission's Strategic Plan for Energy Technologies.

    The growing prevalence of antibiotic resistance calls for new approaches in the development of antimicrobial therapeutics. Likewise, improved diagnostic measures are essential in guiding the application of targeted therapies and preventing the evolution of therapeutic resistance. Discovery platforms are also needed to form new treatment strategies and identify novel antimicrobial agents. By applying engineering principles to molecular biology, synthetic biologists have developed platforms that improve upon, supplement, and will perhaps supplant traditional broad-spectrum antibiotics. Efforts in engineering bacteriophages and synthetic probiotics demonstrate targeted antimicrobial approaches that can be fine-tuned using synthetic biology-derived principles. Further, the development of paper-based, cell-free expression systems holds promise in promoting the clinical translation of molecular biology tools for diagnostic purposes. In this review, we highlight emerging synthetic biology platform technologies that are geared toward the generation of new antimicrobial therapies, diagnostics, and discovery channels.

    The aim of this work is to show the Optical Wireless Link to intraSpacecraft Communications (OWLS) technology as a platform technology for space missions, and more specifically its use within the On-Board Communication system of OPTOS satellite. OWLS technology was proposed by Instituto Nacional de Técnica Aeroespacial (INTA) at the end of the 1990s and developed along 10 years through a number of ground demonstrations, technological developments and in-orbit experiments. Its main benefits are: mass reduction, flexibility, and simplification of the Assembly, Integration and Tests phases. The final step was to go from an experimental technology to a platform one. This step was carried out in the OPTOS satellite, which makes use of optical wireless links in a distributed network based on an OLWS implementation of the CAN bus. OPTOS is the first fully wireless satellite. It is based on the triple configuration (3U) of the popular Cubesat standard, and was completely built at INTA. It was conceived to procure a fast development, low cost, and yet reliable platform to the Spanish scientific community, acting as a test bed for space born science and technology. OPTOS presents a distributed OBDH architecture in which all satellite's subsystems and payloads incorporate a small Distributed On-Board Computer (OBC) Terminal (DOT). All DOTs (7 in total) communicate between them by means of the OWLS-CAN that enables full data sharing capabilities. This collaboration allows them to perform all tasks that would normally be carried out by a centralized On-Board Computer.

    Research and development in the field of energy technologies was and still is a rational necessity of our time. However, the current point of main effort has shifted from security of supply to environmental compatibility and safety of the technological processes used. Nuclear fusion is not expected to provide an extension of currently available energy resources until the middle of the next century. Its technological translation will be measured by the same conditions and issues of political acceptance that are relevant to nuclear technology today. Approaches in the major research establishments to studies of regenerative energy systems as elements of modern energy management have led to research and development programs on solar and hydrogen technologies as well as energy storage. The percentage these systems might achieve in a secured energy supply of European national economies is controversial yet today. In the future, the Arbeitsgemeinschaft Grossforschungseinrichtungen (AGF) (Cooperative of Major Research Establishments) will predominantly focus on nuclear safety research and on areas of nuclear waste disposal, which will continue to be a national task even after a reorganization of cooperation in Europe. In addition, they will above all assume tasks of nuclear plant safety research within international cooperation programs based on government agreements, in order to maintain access for the Federal Republic of Germany to an advancing development of nuclear technology in a concurrent partnership with other countries.

    2016-01-01

    Oil and gas platforms are energy-intensive systems – each facility uses from a few to several hundreds MW of energy, depending on the petroleum properties, export specifications and field lifetime. Several technologies for increasing the energy efficiency of these plants are investigated in this work. They include: (i) the installation of multiple pressure levels in production manifolds, (ii) the implementation of multiphase expanders, (iii) the promotion of energy and process integration, (iv) the limitation of gas recirculation around the compressors, (v) the exploitation of low-temperature heat from the gas cooling steps, (vi) the downsizing or replacement of the existing gas turbines, and (vii) the use of the waste heat from the power plant. The present study builds on four actual cases located in the North and Norwegian Seas, which differ by the type of oil processed, operating conditions and strategies. The benefits and practical limitations of each measure are discussed based on thermodynamic, economic and environmental factors. Significant energy savings and reductions in CO_2-emissions are depicted, reaching up to 15–20%. However, they strongly differ from one facility to another, which suggests that generic improvements can hardly be proposed, and that thorough techno-economic analyses should be conducted for each plant. - Highlights: • Energy efficiency measures for offshore platforms are assessed. • Energy savings and reductions in CO_2-emissions can reach up to 15-20%. • They differ strongly depending on the oil type, operating conditions and strategies.

    The Department of Energy's (DOE) Office of Science and Technology Decontamination and Decommissioning (D andD) Focus Area, led by the National Energy Technology Laboratory, has been charged with finding new and innovative D and D technologies and then validating through field demonstration that the technologies are safer, faster and/or more cost-effective. The D and D Focus Area's approach to verifying the benefits of the improved D and D technologies is to use them at DOE sites in large-scale demonstration and deployment (LSDD) projects. The DOE's Fernald Environmental Management Project (FEMP), near Cincinnati Ohio, was host for a LSDD Project overseen by the D and D Focus Area. The FEMP was formerly engaged in the production of high quality uranium metal; and is now currently undergoing active environmental restoration, including removal of major process facilities. As observed during the D and D of Fernald's Plant 1, the baseline method for removing piping required laborers to work above the floor on ladders, scaffolding, ardor man-lifts with hand-held power tools. The pipe must first be rigged to prevent falling when cut. After cutting, the pipe is manually lowered to the ground and placed in a storage/disposal container. The Mobile Work Platform (MWP) consists of a mobile chassis, telescoping arm and a dual crimper/shear ''end-effecter''. It has the capability to grab and hold a pipe, crimp and shear the pipe (up to a ten-foot section) on either side of where it is being held and then lower and place the pipe section into a storage/disposal container. The MWP can crimp/shear up to a 6-inch diameter, schedule 401, carbon steel pipe. A single operator using a radio remote control operates the MWP. The paper will describe the results (productivity, safety advantages and lessons learned) during the Mobile Work Platform demonstration at Fernald

    Energy storage technologies are valuable components in most energy systems and could be an important tool in achieving a low-carbon future. These technologies allow for the decoupling of energy supply and demand, in essence providing a valuable resource to system operators. There are many cases where energy storage deployment is competitive or near-competitive in today's energy system. However, regulatory and market conditions are frequently ill-equipped to compensate storage for the suite of services that it can provide. Furthermore, some technologies are still too expensive relative to other competing technologies (e.g. flexible generation and new transmission lines in electricity systems). One of the key goals of this new roadmap is to understand and communicate the value of energy storage to energy system stakeholders. This will include concepts that address the current status of deployment and predicted evolution in the context of current and future energy system needs by using a ''systems perspective'' rather than looking at storage technologies in isolation.

    This report on the new energy technologies has been written by a working group on request of the French ministry of economy, finances and industry, of the ministry of ecology and sustainable development, of the ministry of research and new technologies and of the ministry of industry. The mission of the working group is to identify goals and priority ways for the French and European research about the new technologies of energy and to propose some recommendations about the evolution of research incentive and sustain systems in order to reach these goals. The working group has taken into consideration the overall stakes linked with energy and not only the climatic change. About this last point, only the carbon dioxide emissions have been considered because they represent 90% of the greenhouse gases emissions linked with the energy sector. A diagnosis is made first about the present day context inside which the new technologies will have to fit with. Using this diagnosis, the research topics and projects to be considered as priorities for the short-, medium- and long-term have been identified: energy efficiency in transports, in dwellings/tertiary buildings and in the industry, development for the first half of the 21. century of an energy mix combining nuclear, fossil-fuels and renewable energy sources.

    In the Federal Republic of Germany, analyses and forecasts of the energy supply and energy consumption have revealed five major sectors in which extensive R and D activities should be carried out: nuclear energy, coal technology, the utilization of solar energy, techniques for the economical use of energy, and nuclear fusion. Of these sectors, only nuclear energy will be able to make a major contribution to our energy supply both in the near future and over a longer period. The available capacity for mining the large deposits of coal in the Federal Republic of Germany can be increased only gradually and will therefore not make an appreciable contribution until a later date. Another fact to be considered is that a rapidly expanding utilization of this source of energy entails very heavy pollution of the environment. The utilization of solar energy in Central Europe will probably be possible only for supplying warm water for industry and for heating buildings. In the long term, solar energy will contribute only a small percentage of energy to the supply required by the Federal Republic of Germany. Intensive efforts are being made to develop technologies for the more economical use of energy. The priorities in this sector are the installation of district heating systems using waste heat from power stations, and the improved heat insulation of houses. It is not anticipated that the technical utilization of nuclear fusion will be introduced before the end of this century. Nonetheless, this source of energy still constitutes a possibility offering an extremely great potential in the long term, with the result that every effort is being made to put it to good use. The work being carried out in this field in the Federal Republic of Germany is being closely coordinated with the relevant activities undertaken by the other member countries of the European Community.

    Energy and technology are essential ingredients of development, it is only through their use that it became possible to sustain a population of almost 5 billion on Earth. The challenges to eradicate poverty and underdevelopment in developing countries in the face of strong population increases can only be successfully met with the use of advanced technology, leapfrogging the path followed in the past by today's industrialized countries. It is shown in the paper that energy consumption can be decoupled from economic development. Such possibility will contribute significantly in achieving sustainable development. 10 refs., 4 figs., 3 tabs.

    Demming, Anna

    2011-06-01

    Renewable energy is now a mainstream concern among businesses and governments across the world, and could be considered a characteristic preoccupation of our time. It is interesting to note that many of the energy technologies currently being developed date back to very different eras, and even predate the industrial revolution. The fuel cell was first invented as long ago as 1838 by the Swiss--German chemist Christian Friedrich Schönbein [1], and the idea of harnessing solar power dates back to ancient Greece [2]. The enduring fascination with new means of harnessing energy is no doubt linked to man's innate delight in expending it, whether it be to satisfy the drive of curiosity, or from a hunger for entertainment, or to power automated labour-saving devices. But this must be galvanized by the sustained ability to improve device performance, unearthing original science, and asking new questions, for example regarding the durability of photovoltaic devices [3]. As in so many fields, advances in hydrogen storage technology for fuel cells have benefited significantly from nanotechnology. The idea is that the kinetics of hydrogen uptake and release may be reduced by decreasing the particle size. An understanding of how effective this may be has been hampered by limited knowledge of the way the thermodynamics are affected by atom or molecule cluster size. Detailed calculations of individual atoms in clusters are limited by computational resources as to the number of atoms that can studied, and other innovative approaches that deal with force fields derived by extrapolating the difference between the properties of clusters and bulk matter require labour-intensive modifications when extending such studies to new materials. In [4], researchers in the US use an alternative approach, considering the nanoparticle as having the same crystal structure as the bulk but relaxing the few layers of atoms near the surface.

    The NASA Goddard Space Flight Center (GSFC) and the Department of Defense Operationally Responsive Space (ORS) Office are exercising a multi-year collaborative agreement focused on a redefinition of the way space missions are designed and implemented. A much faster, leaner and effective approach to space flight requires the concerted effort of a multi-agency team tasked with developing the building blocks, both programmatically and technologically, to ultimately achieve flights within 7-days from mission call-up. For NASA, rapid mission implementations represent an opportunity to find creative ways for reducing mission life-cycle times with the resulting savings in cost. This in tum enables a class of missions catering to a broader audience of science participants, from universities to private and national laboratory researchers. To that end, the SMART (Small Rocket/Spacecraft Technology) micro-spacecraft prototype demonstrates an advanced avionics system with integrated GPS capability, high-speed plug-and-playable interfaces, legacy interfaces, inertial navigation, a modular reconfigurable structure, tunable thermal technology, and a number of instruments for environmental and optical sensing. Although SMART was first launched inside a sounding rocket, it is designed as a free-flyer.

    2012-01-01

    One decade after the genomic and the proteomic life science revolution, new ‘omics’ fields are emerging. The metabolome encompasses the entity of small molecules—Most often end products of a catalytic process regulated by genes and proteins—with the lipidome being its fat soluble subdivision. Within recent years, lipids are more and more regarded not only as energy storage compounds but also as interactive players in various cellular regulation cycles and thus attain rising interest in the bio-medical community. The field of lipidomics is, on one hand, fuelled by analytical technology advances, particularly mass spectrometry and chromatography, but on the other hand new biological questions also drive analytical technology developments. Compared to fairly standardized genomic or proteomic high-throughput protocols, the high degree of molecular heterogeneity adds a special analytical challenge to lipidomic analysis. In this review, we will take a closer look at various mass spectrometric platforms for lipidomic analysis. We will focus on the advantages and limitations of various experimental setups like ‘shotgun lipidomics’, liquid chromatography—Mass spectrometry (LC-MS) and matrix assisted laser desorption ionization-time of flight (MALDI-TOF) based approaches. We will also examine available software packages for data analysis, which nowadays is in fact the rate limiting step for most ‘omics’ workflows. PMID:24957366

    Full text: The process of developing a technology roadmap for hydrogen is by no means fixed - various approaches, methodologies and tools are available to achieve the same end: a clear strategy with concrete, implementable steps to be taken by specific actor groups on a defined timescale. This paper uses the development of a hydrogen roadmap in Portugal as a case study to illustrate a possible approach. The methodology and tools used are described and appraised, highlighting key advantages and challenges. The methodology adopted in Portugal began with a purely qualitative vision building and analysis component (the Hi-Po project), prior to the development of the actual roadmap under the EDEN project. The latter uses a variety of quantitative computer models, as well as more qualitative stakeholder consultation to assess the potential impacts of the transition to a hydrogen economy (under four possible scenarios of market penetration of hydrogen technologies). The steps of the EDEN methodology can be summarised as follows: - Review of key hydrogen futures literature; - Choice of tools to analyse impacts; - Definition of scope of analysis: the impact of introducing hydrogen in passenger road transport, and domestic combined heat and power, is assessed; - Set-up of a group of key stakeholders, with representation from all the sectors which would be most affected by and have most effect on, the transition to a hydrogen economy; - Creation of a baseline scenario - business as usual situation in the country without a policy specifically aiming to introduce hydrogen; - Development, in consultation with the stakeholder group, of a shared vision for hydrogen in Portugal, including the technologies to be used for production, distribution and use of hydrogen, and the degree of penetration of these technologies into the economy under various scenarios; - Analysis of these scenarios using the chosen tools; - Presentation of preliminary results to the stakeholder group, and

    The technical development of clean energy including the utilization of solar energy was begun in 1973 at the time of the oil crisis, and about 20 years elapsed. Also in Japan, the electric power buying system by electric power companies for solar light electric power and wind electric power has been started in 1992, namely their value as a merchandise was recognized. As for these two technologies, the works of making the international standards and JIS were begun. The range of clean energy or natural energy is wide, and its kinds are many. The utilization of solar heat and the electric power generation utilizing waves, tide and geotherm already reached the stage of practical use. Generally in order to practically use new energy, the problem of price must be solved, but the price is largely dependent on the degree of spread. Also the reliability, durability and safety must be ensured, and the easiness of use, effectiveness and trouble-saving maintenance and operation are required. For the purpose, it is important to packaging those skillfully in a system. The cases of intelligent natural energy systems are shown. Solar light and wind electric power generation systems and the technology of transporting clean energy are described. (K.I.)

    The conservation of energy through the efficiency improvement of existing end-uses and the development of new technologies to replace less efficient systems is an important component of the overall effort to reduce greenhouse gases which may contribute to global climate change. Even though uncertainties exist on the degree and causes of global warming, efficiency improvements in end-use applications remain in the best interest of utilities, their customers and society because efficiency improvements not only reduce environmental exposures but also contribute to industrial productivity, business cost reductions and consumer savings in energy costs.

    Multi-organizational research teams working jointly on projects often encounter problems with discovery, access to relevant existing resources, and data sharing due to large file sizes, inappropriate file formats, or other inefficient options that make collaboration difficult. The Energy Data eXchange (EDX) from Department of Energy's (DOE) National Energy Technology Laboratory (NETL) is an evolving online research environment designed to overcome these challenges in support of DOE's fossil energy goals while offering improved access to data driven products of fossil energy R&D such as datasets, tools, and web applications. In 2011, development of NETL's Energy Data eXchange (EDX) was initiated and offers i) a means for better preserving of NETL's research and development products for future access and re-use, ii) efficient, discoverable access to authoritative, relevant, external resources, and iii) an improved approach and tools to support secure, private collaboration and coordination between multi-organizational teams to meet DOE mission and goals. EDX presently supports fossil energy and SubTER Crosscut research activities, with an ever-growing user base. EDX is built on a heavily customized instance of the open source platform, Comprehensive Knowledge Archive Network (CKAN). EDX connects users to externally relevant data and tools through connecting to external data repositories built on different platforms and other CKAN platforms (e.g. Data.gov). EDX does not download and repost data or tools that already have an online presence. This leads to redundancy and even error. If a relevant resource already has an online instance, is hosted by another online entity, EDX will point users to that external host either using web services, inventorying URLs and other methods. EDX offers users the ability to leverage private-secure capabilities custom built into the system. The team is presently working on version 3 of EDX which will incorporate big data analytical

    The advent of DNA sequencing technologies and the various applications that can be performed will have a dramatic effect on medicine and healthcare in the near future. There are several DNA sequencing platforms available on the market for research and clinical use. Based on the medical laboratory scientist or researcher's needs and taking into consideration laboratory space and budget, one can chose which platform will be beneficial to their institution and their patient population. Although some of the instrument costs seem high, diagnosing a patient quickly and accurately will save hospitals money with fewer hospital stays and targeted treatment based on an individual's genetic make-up. By determining the type of disease an individual has, based on the mutations present or having the ability to prescribe the appropriate antimicrobials based on the knowledge of the organism's resistance patterns, the clinician will be better able to treat and diagnose a patient which ultimately will improve patient outcomes and prognosis.

    The Finnish Technology Development Centre (Tekes) is responsible for the financing of research and development in the field of energy production technology. A considerable part of the financing goes to technology programmes. Each technology programme involves major Finnish institutions - companies, research institutes, universities and other relevant interests. Many of the energy technology programmes running in 1998 were launched collectively in 1993 and will be completed at the end of 1998. They are complemented by a number of other energy-related technology programmes, each with a timetable of its own. Because energy production technology is horizontal by nature, it is closely connected with research and development in other fields, too, and is an important aspect in several other Tekes technology programmes. For this reason this brochure also presents technology programmes where energy is only one of the aspects considered but which nevertheless contribute considerably to research and development in the energy production sector

  8. Energy modelling platforms for policy and strategy support

    Dyner, I.

    2000-01-01

    The energy field has been dominated by 'hard' modelling approaches by researchers from engineering and economics discipline. The recent trend towards a more liberalised environment moves away from central planning to market-based resource allocation, leading to the creation and use of strategic tools, with much 'softer' specifications, in the 'system-thinking' tradition. This paper presents the use of system dynamics in a generalised way, to provide a platform for integrated energy analysis. Issues of modularity and policy evolution are important in the design of the modelling platform to facilitate its use, and reuse. Hence the concepts of a platform, rather than a model, has to be implemented in a coherent way if it is to provide sustained value for ongoing support to both government policy and corporate strategy.

    A common concern in smart cities is the focus on sensing procedures to provide city-wide information to city managers and citizens. To meet the growing demands of smart cities, the network must provide the ability to handle a large number of mobile sensors/devices, with high heterogeneity and unpredictable mobility, by collecting and delivering the sensed information for future treatment. This work proposes a multi-wireless technology communication platform for opportunistic data gathering and data exchange with respect to smart cities. Through the implementation of a proprietary long-range (LoRa) network and an urban sensor network, our platform addresses the heterogeneity of Internet of Things (IoT) devices while conferring communications in an opportunistic manner, increasing the interoperability of our platform. It implements and evaluates a medium access communication (MAC) protocol for LoRa networks with multiple gateways. It also implements mobile Opportunistic VEhicular (mOVE), a delay-tolerant network (DTN)-based architecture to address the mobility dimension. The platform provides vehicle-to-everything (V2X) communication with support for highly reliable and actionable information flows. Moreover, taking into account the high mobility pattern that a smart city scenario presents, we propose and evaluate two forwarding strategies for the opportunistic sensor network.

With regard to competition among vendors in the highly technological nuclear sector, where investments for new build contribute about 70% of the total generation costs, improvement in competitiveness is needed. Like all Technology Platforms under the 7. Framework Program, the Sustainable Nuclear Energy Technology Platform (SNETP) is a Europe-wide forum and is gathering stakeholders from the nuclear community (5). Its overall goal is to enhance the sustainability of nuclear fission by supporting technological development. It is worth pointing out, that nuclear is addressed as 'sustainable' energy. The SNETP was launched in 2007 and ensures actions for ensuring sustainability of nuclear power in the field of: - Ensure long term safe operation of current Generation II reactors, - Built and ensure safety and competitiveness of evolutionary Gen III reactors, - Develop Gen IV fast breeders with closed fuel cycle, - Enlarge the nuclear fission portfolio beyond electricity production: H2, synthetic fuels, H{sub 2}O desalination, paper, cement industry, and - Developing Research Infrastructures. EON Kernkraft supports this initiative gives feedback of current Generation-II fleet operations and topics for the deployment of new technologies. We are active in the SNETP in several organisation bodies, and are also in direct cooperation with research organisations, e.g. CEA.

    This paper reports research achievements in fiscal 1998 for a platform for designing high functional materials. Since coarse-grained models used in molecular dynamics (MD) simulation are diversified depending on materials, phenomena and properties, a general purpose MD engine that can simulate them freely was designed. Methods were developed to determine the potentials of coarse-grained models from the atomistic models. In polymer melts, very slow movements caused by entanglements have a substantially important role, which are difficult to be studied by usual MD simulations. Therefore, fiscal 1998 has devised a coarse-grained model to handle slow movements of straight-chain polymers, and a rheological forecast program was prepared. Studies are also being made on meso-scale structures sufficiently large as compared to atoms and on dynamic property forecast. Works were carried out to develop a simulator, in which polymeric phenomena with large spatio-temporal scale are applied with a continuity model to solve the equation thereof. Improvements were given on the hardware/software environments required for developing simulation engines and platforms for mesoscopic region. (NEDO)

    The mission of the Personalized Energy Reduction Cyber-physical System (PERCS) is to create new possibilities for improving building operating efficiency, enhancing grid reliability, avoiding costly power interruptions, and mitigating greenhouse gas emissions. PERCS proposes to achieve these outcomes by engaging building occupants as partners in a user-centered smart service platform. Using a non-intrusive load monitoring approach, PERCS uses a single sensing point in each home to capture smart electric meter data in real time. The household energy signal is disaggregated into individual load signatures of common appliances (e.g., air conditioners), yielding near real-time appliance-level energy information. Users interact with PERCS via a mobile phone platform that provides household- and appliance-level energy feedback, tailored recommendations, and a competitive game tied to energy use and behavioral changes. PERCS challenges traditional energy management approaches by directly engaging occupant as key elements in a technological system.

    Recombinant antibody fragments are being used for the last few years as an important therapeutic protein to cure various critical and life threatening human diseases. Several expression platforms now days employed for the production of these recombinant fragments, out of which bacterial system has emerged a promising host for higher expression. Since, a small antibody fragment unlike full antibody does not require human-like post-translational modification therefore it is potentially expressed in prokaryotic production system. Recently, small antibody fragments such as scFvs (single-chain variable fragments) and Fabs (antibody fragments) which does not require glycosylation are successfully produced in bacteria and have commercially launched for therapeutic use as these fragments shows better tissue penetration and less immunogenic to human body compared to full-size antibody. Recently developed Wacker's ESETEC secretion technology is an efficient technology for the expression and secretion of the antibody fragment (Fab) exceeded up to 4.0 g/L while scFv up to 3.5 g/L into the fermentation broth. The Pfenex system and pOP prokaryotic expression vector are another platform used for the considerably good amount of antibody fragment production successfully. In this review, we summarize the recent progress on various expression platforms and cloning approaches for the production of different forms of antibody fragments in E. coli.

    Biomedical sensors have been widely used in various areas of biomedical practices, which play an important role in disease detection, diagnosis, monitoring, treatment, health management, and so on. However, most of them and their related platforms are generally not easily accessible or just too expensive or complicated to be kept at home. As an alternative, new technologies enabled from the mobile phones are gradually changing such situations. As can be freely available to almost everyone, mobile phone offers a unique way to improve the conventional medical care through combining with various biomedical sensors. Moreover, the established systems will be both convenient and low cost. In this paper, we present an overview on the state-of-art biomedical sensors, giving a brief introduction of the fundamental principles and showing several new examples or concepts in the area. The focus was particularly put on interpreting the technical strategies to innovate the biomedical sensor technologies based on the platform of mobile phones. Some challenging issues, including feasibility, usability, security, and effectiveness, were discussed. With the help of electrical and mechanical technologies, it is expected that a full combination between the biomedical sensors and mobile phones will bring a bright future for the coming pervasive medical care.

    A comprehensive assessment of different energy systems from the economic point of view has to be based on data showing all relevant costs incurred and benefits drawn by the society from the use of such energy systems, i.e. internal costs and benefits visible to the energy consumer as prices paid for power supplied, as well as external costs and benefits. External costs or benefits of energy systems cover among other items employment or wage standard effects, energy-induced environmental impacts, public expenditure for pollution abatement and mitigation of risks and effects of accidents, and the user costs connected with the exploitation of reserves, which are not rated high enough to really reflect and demonstrate the factor of depletion of non-renewable energy sources, as e.g. fossil reserves. Damage to the natural and social environment induced by anthropogenous air pollutants up to about 90% counts among external costs of energy conversion and utilisation. Such damage is considered to be the main factor of external energy costs, while the external benefits of energy systems currently are rated to be relatively unsignificant. This means that an internalisation of external costs would drive up current prices of non-renewable energy sources, which in turn would boost up the economics of renewable energy sources, and the hydrogen produced with their energy. Other advantages attributed to most of the renewable energy sources and to hydrogen energy systems are better environmental compatibility, and no user costs. (orig.) [de

    Full Text Available The article discloses the economic content of technological platform (TP as a system of transactional relations of its participants, which provides the most beneficial interactions on the basis of a common goal and unity of interests. TP can generate clusters corresponding to its profile, based on common basic technologies. Reduction of the meaning of TPs and clusters to the notion of an “instrument” of economic policy hinders the disclosure of their economic content, which becomes a relevant theoretical problem and a barrier to the effective use of TPs in nanoindustry. Creation of nanotechnology platforms didn’t become an independent direction, however, RUSNANO became the coordinator and participant of 6 TPs. With RUSNANO participation 6 innovative clusters have been created, and 5 more within 10 years. Further development of Russian nanoindustry cannot be related only to clustering at macrolevel, but involves horizontal integration of nanotechnologies into various country’s specific TPs and vertical integration into TPs and clusters at the EAEU (Eurasian Economic Union scale. Nanotechnology projects financing in Eurasian TPs is attributed to the most complicated problems of their functioning, taking into account the insufficient rates of integration in the EAEU. The article argues the feasibility of financing Eurasian nanoindustry TPs on the basis of public-private partnership mechanism and the need to shift from its budgetary part to extra-budgetary as the “life cycle” of the TP develops, and its institutional and organizational maturity is increased. This will allow Russian and Eurasian TPs to realize their significant potential of resourcing the domestic nanoindustry development.

    Koopman, R.; Lamont, A.; Schock, R.

    1992-09-01

    Energy security was identified in the National Energy Strategy (NES) as a major issue for the Department of Energy (DOE). As part of a process designed by the DOE to identify technologies important to implementing the NES, an expert working group was convened to consider which technologies can best contribute to reducing the nation's economic vulnerability to future disruptions of world oil supplies, the working definition of energy security. Other working groups were established to deal with economic growth, environmental quality, and technical foundations. Energy Security working group members were chosen to represent as broad a spectrum of energy supply and end-use technologies as possible and were selected for their established reputations as experienced experts with an ability to be objective. The time available for this evaluation was very short. The group evaluated technologies using criteria taken from the NES which can be summarized for energy security as follows: diversifying sources of world oil supply so as to decrease the increasing monopoly status of the Persian Gulf region; reducing the importance of oil use in the US economy to diminish the impact of future disruptions in oil supply; and increasing the preparedness of the US to deal with oil supply disruptions by having alternatives available at a known price. The result of the first phase of the evaluation process was the identification of technology groups determined to be clearly important for reducing US vulnerability to oil supply disruptions. The important technologies were mostly within the high leverage areas of oil and gas supply and transportation demand but also included hydrogen utilization, biomass, diversion resistant nuclear power, and substitute industrial feedstocks.

This paper presents an operational flash flood forecasting platform which have been developed in the framework of CYCLOPS European project providing one of virtual organizations of EGEE project. This platform has been designed to enable multi-simulations processes to ease forecasting operations of several supervised watersheds on Grand Delta (SPC-GD) territory. Grid technology infrastructure, in providing multiple remote computing elements enables the processing of multiple rainfall scenarios, derived to the original meteorological forecasting transmitted by Meteo-France, and their respective hydrological simulations. First results show that from one forecasting scenario, this new presented approach can permit simulations of more than 200 different scenarios to support forecasters in their aforesaid mission and appears as an efficient hydrological decision-making tool. Although, this system seems operational, model validity has to be confirmed. So, further researches are necessary to improve models core to be more efficient in term of hydrological aspects. Finally, this platform could be an efficient tool for developing others modelling aspects as calibration or data assimilation in real time processing.

    The paper cites three practical propositions to furnish viable green energy in the Biofuels, Clean Coal Processes, and Windmill sectors. We share our experience on indigenous fabrication of 500 W, 1.5 m windmill rotors with a hub height of 6.0 m above ground level as part of NUST-AERO-Fiber Tech outreach industrial link project. Mirror process with matching receptacles is used to fabricate the windmill rotors according to NACA aero foil profile. Full scale load-deflection/bending stiffness tests are conducted using simulated aerodynamic load with incremental loading. An avg. bending stiffness of 14.85 KN/m and mean displacement of 21.17 mm for the maximum applied load of 0.35 KN is recorded at a loading rate of 0.05 KN/sec. for a full scale load range of 25 KN. These results demonstrate that the manufactured composite rotors had adequate structural integrity, subsequently verified in actual windmill operation at 400 rpm. The installed windmill now adorns the skyline of NUST. Fast Track liquid bio fuels are produced from non-edible crop oil using bimodal nano materials. In a process developed at SCME NUST, a conversion to bio diesel time of 5 min. at 25 deg. C is achieved compared to 90 min. at 70 deg. C for the conventional hydroxide catalyst route. The process parameters, characterization and evaluation testing are presented. (author)

    Increasing the number as well as improving the capacity and quality of medical professionals to achieve an equitable health care for all is a global priority and a global challenge. In developing countries, which are facing the largest burden of disease, to achieve the above stated objective, there is a big need for more well-trained, competent and dedicated health care providers. Currently, there is a well-documented shortage of trained health workers globally, with the poorest countries having the greatest shortfalls. The time tested, traditional approach of training health care force by importing professionals from overseas is not only prohibitively expensive but also not sufficient to achieve the scale and pace of the required human capacity building. Considering this fact, distance learning programs, which include m-Health as well as other information technology (IT) platforms and tools, can provide unique, timely, cost-effective, easily scalable and valuable opportunities to expand access to training health care manpower in developing countries where the shortage is critical.

    Nearly all industrial facilities have been responsible for introducing synthetic chemicals into the environment. The Savannah River Site is no exception. Several areas at the site have been contaminated by chlorinated volatile organic chemicals. Because of the persistence and refractory nature of these contaminants, a complete clean up of the site will take many years. A major focus of the mission of the Environmental Sciences Section of the Savannah River Technology Center is to develop better, faster, and less expensive methods for characterizing, monitoring, and remediating the subsurface. These new methods can then be applied directly at the Savannah River Site and at other contaminated areas in the United States and throughout the world. The Environmental Sciences Section has hosted field testing of many different monitoring technologies over the past two years primarily as a result of the Integrated Demonstration Program sponsored by the Department of Energy's Office of Technology Development. This paper provides an overview of some of the technologies that have been demonstrated at the site and briefly discusses the applicability of these techniques

    2010-01-01

    Commercialization efforts to diffuse sustainable energy technologies (SETs) have so far remained as the biggest challenge in the field of renewable energy and energy efficiency. Limited success of diffusion through government driven pathways urges the need for market based approaches. This paper reviews the existing state of commercialization of SETs in the backdrop of the basic theory of technology diffusion. The different SETs in India are positioned in the technology diffusion map to reflect their slow state of commercialization. The dynamics of SET market is analysed to identify the issues, barriers and stakeholders in the process of SET commercialization. By upgrading the 'potential adopters' to 'techno-entrepreneurs', the study presents the mechanisms for adopting a private sector driven 'business model' approach for successful diffusion of SETs. This is expected to integrate the processes of market transformation and entrepreneurship development with innovative regulatory, marketing, financing, incentive and delivery mechanisms leading to SET commercialization.

    1998-12-01

    The US Department of Energy (DOE) and the Federal Energy Technology Center (FETC) has developed a Large Scale Demonstration Project (LSDP) at the Chicago Pile-5 Research Reactor (CP-5) at Argonne National Laboratory-East (ANL). The objective of the LSDP is to demonstrate potentially beneficial Deactivation and Decommissioning (D and D) technologies in comparison with current baseline technologies. The Dual Arm Work Platform (DAWP) demonstration focused on the use of the DAWP to segment and dismantle the CP-5 reactor tank and surrounding bio-shield components (including the graphite block reflector, lead and boral sheeting) and performing some minor tasks best suited for the use of teleoperated robotics that were not evaluated in this demonstration. The DAWP system is not a commercially available product at this time. The CP-5 implementation was its first D and D application. The demonstration of the DAWP was to determine the areas on which improvements must be made to make this technology commercially viable. The results of the demonstration are included in this greenbook. It is the intention of the developers to incorporate lessons learned at this demonstration and current technological advancements in robotics into the next generation of the DAWP

    This report has been prepared by the US Department of Energy (DOE) as part of a Research Development Demonstration Testing and Evaluation (RDDT ampersand E) project by EG ampersand G Energy Measurement's (EG ampersand G/EM) Remote Sensing Laboratory. It examines geophysical detection techniques which may be used in Environmental Restoration/Waste Management (ER/WM) surveys to locate buried waste, waste containers, potential waste migratory paths, and aquifer depths. Because of the Remote Sensing Laboratory's unique survey capabilities, only those technologies which have been adapted or are capable of being adapted to an airborne platform were studied. This survey describes several of the available subsurface survey technologies and discusses the basic capabilities of each: the target detectability, required geologic conditions, and associated survey methods. Because the airborne capabilities of these survey techniques have not been fully developed, the chapters deal mostly with the ground-based capabilities of each of the technologies, with reference made to the airborne capabilities where applicable. The information about each survey technique came from various contractors whose companies employ these specific technologies. EG ampersand G/EM cannot guarantee or verify the accuracy of the contractor information; however, the data given is an indication of the technologies that are available

    2016-01-01

    Full Text Available Application development platform is the most important environment in IT industry. There are a variety of platforms. Although the native development enables application to optimize, various languages and software development kits need to be acquired according to the device. The coexistence of smart devices and platforms has rendered the native development approach time and cost consuming. Cross-platform development emerged as a response to these issues. These platforms generate applications for multiple devices based on web languages. Nevertheless, development requires additional implementation based on a native language because of the coverage and functions of supported application programming interfaces (APIs. Wearable devices have recently attracted considerable attention. These devices only support Bluetooth-based interdevice communication, thereby making communication and device control impossible beyond a certain range. We propose Network Application Agent (NetApp-Agent in order to overcome issues. NetApp-Agent based on the Cordova is a wearable device control platform for the development of network applications, controls input/output functions of smartphones and wearable/IoT through the Cordova and Native API, and enables device control and information exchange by external users by offering a self-defined API. We confirmed the efficiency of the proposed platform through experiments and a qualitative assessment of its implementation.

    The development of high-tech industry has been prosperous around the world in past decades, while technology and finance have already become the most significant issues in the information era. While high-tech firms are a major force behind a country's economic development, it requires a lot of money for the development process, as well as the financing difficulties for its potential problems, thus, how to evaluate and establish appropriate technology and financial services platforms innovation strategy has become one of the most critical and difficult issues. Moreover, how the chosen intertwined financial environment can be optimized in order that high-tech firms financing problems can be decided has seldom been addressed. Thus, this research aims to establish a technology and financial services platform innovation strategy improvement model, as based on the hybrid MADM model, which addresses the main causal factors and amended priorities in order to strengthen ongoing planning. A DEMATEL technique, as based on Analytic Network Process, as well as modified VIKOR, will be proposed for selecting and re-configuring the aspired technology and financial services platform. An empirical study, as based on China's technology and financial services platform innovation strategy, will be provided for verifying the effectiveness of this proposed methodology. Based on expert interviews, technology and financial services platforms innovation strategy improvement should be made in the following order: credit guarantee platform ( C )_credit rating platform ( B )_investment and finance platform ( A ).

  18. Tidal energy - a technology review

    International Nuclear Information System (INIS)

    Price, R.

    1991-01-01

    The tides are caused by gravitational attraction of the sun and the moon acting upon the world's oceans. This creates a clean renewable form of energy which can in principle be tapped for the benefit of mankind. This paper reviews the status of tidal energy, including the magnitude of the resource, the technology which is available for its extraction, the economics, possible environmental effects and non-technical barriers to its implementation. Although the total energy flux of the tides is large, at about 2 TW, in practice only a very small fraction of this total potential can be utilised in the foreseeable future. This is because the energy is spread diffusely over a wide area, requiring large and expensive plant for its collection, and is often available remote from centres of consumption. The best mechanism for exploiting tidal energy is to employ estuarine barrages at suitable sites with high tidal ranges. The technology is relatively mature and components are commercially available now. Also, many of the best sites for implementation have been identified. However, the pace and extent of commercial exploitation of tidal energy is likely to be significantly influenced, both by the treatment of environmental costs of competing fossil fuels, and by the availability of construction capital at modest real interest rates. The largest projects could require the involvement of national governments if they are to succeed. (author) 8 figs., 2 tabs., 19 refs

    This paper presents the experimental results from the EnergyNest 2 × 500 kWhth thermal energy storage (TES) pilot system installed at Masdar Institute of Science & Technology Solar Platform. Measured data are shown and compared to simulations using a specially developed computer program to verify the stability and performance of the TES. The TES is based on a solid-state concrete storage medium (HEATCRETE®) with integrated steel tube heat exchangers cast into the concrete. The unique concrete recipe used in the TES has been developed in collaboration with Heidelberg Cement; this material has significantly higher thermal conductivity compared to regular concrete implying very effective heat transfer, at the same time being chemically stable up to 450 °C. The demonstrated and measured performance of the TES matches the predictions based on simulations, and proves the operational feasibility of the EnergyNest concrete-based TES. A further case study is analyzed where a large-scale TES system presented in this article is compared to two-tank indirect molten salt technology.

  20. High energy beam manufacturing technologies

    International Nuclear Information System (INIS)

    Geskin, E.S.; Leu, M.C.

    1989-01-01

    Technological progress continues to enable us to utilize ever widening ranges of physical and chemical conditions for material processing. The increasing cost of energy, raw materials and environmental control make implementation of advanced technologies inevitable. One of the principal avenues in the development of material processing is the increase of the intensity, accuracy, flexibility and stability of energy flow to the processing site. The use of different forms of energy beams is an effective way to meet these sometimes incompatible requirements. The first important technological applications of high energy beams were welding and flame cutting. Subsequently a number of different kinds of beams have been used to solve different problems of part geometry control and improvement of surface characteristics. Properties and applications of different specific beams were subjects of a number of fundamental studies. It is important now to develop a generic theory of beam based manufacturing. The creation of a theory dealing with general principles of beam generation and beam-material interaction will enhance manufacturing science as well as practice. For example, such a theory will provide a format approach for selection and integration of different kinds of beams for a particular application. And obviously, this theory will enable us to integrate the knowledge bases of different manufacturing technologies. The War of the Worlds by H. G. Wells, as well as a number of more technical, although less exciting, publications demonstrate both the feasibility and effectiveness of the generic approach to the description of beam oriented technology. Without any attempt to compete with Wells, we still hope that this volume will contribute to the creation of the theory of beam oriented manufacturing

    A two-year effort focused on applying ASCI technology developed for the analysis of weapons systems to the state-of-the-art accident analysis of a nuclear reactor system was proposed. The Sandia SIERRA parallel computing platform for ASCI codes includes high-fidelity thermal, fluids, and structural codes whose coupling through SIERRA can be specifically tailored to the particular problem at hand to analyze complex multiphysics problems. Presently, however, the suite lacks several physics modules unique to the analysis of nuclear reactors. The NRC MELCOR code, not presently part of SIERRA, was developed to analyze severe accidents in present-technology reactor systems. We attempted to: (1) evaluate the SIERRA code suite for its current applicability to the analysis of next generation nuclear reactors, and the feasibility of implementing MELCOR models into the SIERRA suite, (2) examine the possibility of augmenting ASCI codes or alternatives by coupling to the MELCOR code, or portions thereof, to address physics particular to nuclear reactor issues, especially those facing next generation reactor designs, and (3) apply the coupled code set to a demonstration problem involving a nuclear reactor system. We were successful in completing the first two in sufficient detail to determine that an extensive demonstration problem was not feasible at this time. In the future, completion of this research would demonstrate the feasibility of performing high fidelity and rapid analyses of safety and design issues needed to support the development of next generation power reactor systems

  5. Room-temperature ionic liquids and composite materials: platform technologies for CO(2) capture.

    2010-01-19

    Clean energy production has become one of the most prominent global issues of the early 21st century, prompting social, economic, and scientific debates regarding energy usage, energy sources, and sustainable energy strategies. The reduction of greenhouse gas emissions, specifically carbon dioxide (CO(2)), figures prominently in the discussions on the future of global energy policy. Billions of tons of annual CO(2) emissions are the direct result of fossil fuel combustion to generate electricity. Producing clean energy from abundant sources such as coal will require a massive infrastructure and highly efficient capture technologies to curb CO(2) emissions. Current technologies for CO(2) removal from other gases, such as those used in natural gas sweetening, are also capable of capturing CO(2) from power plant emissions. Aqueous amine processes are found in the vast majority of natural gas sweetening operations in the United States. However, conventional aqueous amine processes are highly energy intensive; their implementation for postcombustion CO(2) capture from power plant emissions would drastically cut plant output and efficiency. Membranes, another technology used in natural gas sweetening, have been proposed as an alternative mechanism for CO(2) capture from flue gas. Although membranes offer a potentially less energy-intensive approach, their development and industrial implementation lags far behind that of amine processes. Thus, to minimize the impact of postcombustion CO(2) capture on the economics of energy production, advances are needed in both of these areas. In this Account, we review our recent research devoted to absorptive processes and membranes. Specifically, we have explored the use of room-temperature ionic liquids (RTILs) in absorptive and membrane technologies for CO(2) capture. RTILs present a highly versatile and tunable platform for the development of new processes and materials aimed at the capture of CO(2) from power plant flue gas and

    2003-01-01

    Calgary based Sustainable Energy Technologies is a public company that develops and manufactures alternative energy products that enable distributed renewable energy resources to be integrated with the existing electrical infrastructure. The company has moved from a development stage company to one that manufactures power electronic products that can compete globally and which will play an important role in the transition to a cleaner world. Achievements in the past year have included a joint effort with RWE Piller GmbH to develop a power electronics platform for a fuel cell inverter. Ten inverters were delivered to Nuvera Fuel Cells and were reported to have performed very well in the Avanti distributed generation fuel cell. The universality of the inverter was demonstrated when the same power electronics platform was used to support a 5 kW grid interactive converter for the solar power market. During the 18-month period ending on March 31, 2003, the company invested $1.5 million to create their first two commercial product lines, without net investment of shareholder equity. The objective for the future is to generate cash flow and earnings from sales into the solar power market and to build a leadership role in the stationary fuel cell industry. The major challenge will lie in product support and customer service. As the customer base expands, the company will invest in product-tracking software. This annual report includes an auditor's report, consolidated financial statements including balance sheets, statements of income and deficit, statements of cash flows, and notes to the consolidated financial statements. tabs

    2009-01-01

    Singapore is considered as an interesting example: this country has become the third world oil refining centre and the first Asian oil trade place, but has also implemented a series of strategic measures to promote a sustainable development. The Singapore Green Plan was launched in 1992 and defines important objectives in terms of reduction of carbon emissions, of water consumption, of improvement of waste management services, and so on. This policy results in investments in experimental programs for the development of new energy technologies. This paper presents the public actors (institutions and public agencies) and their projects, the academic projects and programs, and the private sector projects. These programs and projects are concerning the search for clean energies, the development of the solar capacity, various renewable energies, or the automotive industry (projects conducted by Bosch, Renault and Nissan, Daimler, this last one on biofuels)

    Amongst the important scientific and technological revolutions of history there is none in which women have played such a substantial and many-sided role as in the development of nuclear energy. The birth of nuclear energy is not only due to Marie Curie and Lise Meitner but also to a large number of courageous 'nuclear women' who decided against all sorts of prejudices and resistances in favour of a life in research. Therefore the revolution of the atom has also become the greatest breakthrough of women in natural sciences. This double revolution is the subject of this book. Here the history of nuclear energy itself is dealt with documented with the original work and personal memories of different persons - mainly women - who have been substantially involved in this development.

    The research and development program SIHTI was carried out during 1991-1992, mainly concentrating on energy and environmental technology. SIHTI focused on examining emissions from various sources of energy in all stages of the production chain. The objective was to create new methods and equipment, with which the environmental drawbacks of energy production can be reduced. Also a development work aiming at reduced traffic emissions was included in the program. Totally the program included 53 projects, which were divided into the following subsections: energy production, traffic, fuel chains and other projects. In the energy production projects the main attention was paid to reduction of sulphur dioxide, nitrogen oxide and particulate emissions. Furthermore waste utilization and possibilities of reducing carbon dioxide emissions were studied. The traffic study was focused on developing of more environmental-friendly liquid fuels. The research of emissions at low ambient temperatures was developed to an international level. Further the use of gases and the rape seed oil ester as traffic fuel was studied in practical tests. In the fuel chain study the emissions from the most important fuel chains were examined all the way from the purchase of the primary energy to the final end product. Methods for further reduction of water discharges from peat production were developed. The other projects were concentrated on modelling development, environmental impact assessment and emission surveys

    Energy Technology Data Exchange (ETDEWEB)

    2010-06-15

    The Danish Energy Agency and Energinet.dk, the Danish electricity transmission and system operator, have at regular intervals published a catalogue of energy producing technologies. The previous edition was published in March 2005. This report presents the results of the most recent update. The primary objective of publishing a technology catalogue is to establish a uniform, commonly accepted and up-to-date basis for energy planning activities, such as future outlooks, evaluations of security of supply and environmental impacts, climate change evaluations, and technical and economic analyses, e.g. on the framework conditions for the development and deployment of certain classes of technologies. With this scope in mind, it has not been the intention to establish a comprehensive catalogue, including all main gasification technologies or all types of electric batteries. Only selected, representative, technologies are included, to enable generic comparisons of e.g. thermal gasification versus combustion of biomass and electricity storage in batteries versus hydro-pumped storage. It has finally been the intention to offer the catalogue for the international audience, as a contribution to similar initiatives aiming at forming a public and concerted knowledge base for international analyses and negotiations. A guiding principle for developing the catalogue has been to rely primarily on well-documented and public information, secondarily on invited expert advice. Since many experts are reluctant in estimating future quantitative performance data, the data tables are not complete, in the sense that most data tables show several blank spaces. This approach has been chosen in order to achieve data, which to some extent are equivalently reliable, rather than to risk a largely incoherent data set including unfounded guesstimates. The ambition of the present publication has been to reduce the level of inconsistency to a minimum without compromising the fact that the real world

    2017-07-01

    Full Text Available Currently, the exchange cycles of various computers, smartphones, tablets, and others have become shorter, because new high-performance devices continue to roll out rapidly. However, existing legacy devices are not old-fashioned or obsolete to use. From the perspective of sustainable information technology (IT, energy-efficient virtualization can apply a way to increase reusability for special customized devices and enhance the security of existing legacy devices. It means that the virtualization can customize a specially designed purpose using the guest domain from obsolete devices. Thus, this could be a computing scheme that keeps energy supplies and demands in balance for future sustainable IT. Moreover, energy-efficient virtualization can be the long-term and self-sustainable solution such as cloud computing, big data and so forth. By separating the domain of the host device based on virtualization, the guest OS on the segmented domain can be used as a Trusted Execution Environment to perform security features. In this paper, we introduce a secure platform to protect sensitive user data by domain isolation utilizing virtualization. The sensitive user data on our secure platform can protect against the infringement of personal information by malicious attacks. This study is an effective solution in terms of sustainability by recycling them for special purposes or enhancing the security of existing devices.

    2007-01-01

    Innovation has been a driving force for the success of nuclear energy and remains essential for its sustainable future. Many research and development programmes focus on enhancing the performance of power plants in operation, current fuel design and characteristics, and fuel cycle processes used in existing facilities. Generally performed under the leadership of the industry. Some innovation programmes focus on evolutionary reactors and fuel cycles, derived from systems of the current generation. Such programmes aim at achieving significant improvements, in the field of economics or resource management for example, in the medium term. Often, they are undertaken by the industry with some governmental support as they require basic research together with technological development and adaptation. Finally, large programmes, often undertaken in an international, intergovernmental framework are devoted to design and development of a new generation of systems meeting the goals of sustainable development in the long term. Driving forces for nuclear innovation vary depending on the target technology, the national framework and the international context surrounding the research programme. However, all driving factors can be grouped in three categories: market drivers, political drivers and technology drivers. Globally, innovation in the nuclear energy sector is a success story but is a lengthy process that requires careful planning and adequate funding to produce successful outcomes

    2012-01-01

    In the pharmaceutical industry, new drugs are tested to find appropriate compounds for therapeutic purposes for contemporary diseases. Unfortunately, novel compounds emerge at expensive prices and current target evaluation processes have limited throughput, thus leading to an increase of cost and time for drug development. This work shows the development of the novel inkjet-based deposition method for assembling a miniature drug-screening platform, which can realistically and inexpensively evaluate biochemical reactions in a picoliter-scale volume at a high speed rate. As proof of concept, applying a modified Hewlett Packard model 5360 compact disc printer, green fluorescent protein expressing Escherichia coli cells along with alginate gel solution have been arrayed on a coverslip chip under a repeatable volume of 180% ± 26% picoliters per droplet; subsequently, different antibiotic droplets were patterned on the spots of cells to evaluate the inhibition of bacteria for antibiotic screening. The proposed platform was compared to the current screening process, validating its effectiveness. The viability and basic function of the printed cells were evaluated, resulting in cell viability above 98% and insignificant or no DNA damage to human kidney cells transfected. Based on the reduction of investment and compound volume used by this platform, this technique has the potential to improve the actual drug discovery process at its target evaluation stage. (paper)

    The generally acknowledged sources of renewable energy are wind, geothermal, biomass, solar, hydropower, and hydrogen. Renewable energy technologies are crucial to the production and utilization of energy from these regenerative and virtually inexhaustible sources. Furthermore, renewable energy technologies provide benefits beyond the establishment of sustainable energy resources. For example, these technologies produce negligible amounts of greenhouse gases and other pollutants in providing energy, and they exploit domestically available energy sources, thereby reducing our dependence on both the importation of fossil fuels and the use of nuclear fuels. The market price of renewable energy technologies does not reflect the economic value of these added benefits.

    Matson, R.J. [National Renewable Energy Lab., Golden, CO (United States); Carasso, M.

    1999-01-01

    A study of the economic, social-political, and environmental consequences of using renewable energy technologies (RETs, e.g., photovoltaics, wind, solar thermal, biofuels) as compared to those of conventional energy technologies (CETs e.g., oil, coal, gas) would show that RETs are singularly consistent with a whole ethic that is implicit in the concept of sustainability. This paper argues for sustainability as an ethical, as well as a pragmatic, imperative and for RETs as an integral part of this imperative. It brings to the fore some of the specific current economic, political, and environmental assumptions and practices that are inconsistent with both sustainability and with a rapid deployment of RETs. Reflecting an emerging planetary awareness and a pressing need to come to terms with intra- and intergenerational equity, the concept of sustainability explicitly entails the right of future generations to the same opportunity of access to a healthy ecological future and the finite endowment of the Earth`s resources as that of the present generation.

    Centralized computers have been replaced by 'client/server' distributed architectures which are in turn in competition with new distributed systems known as 'peer to peer'. These new technologies are widely spread, and trading, industry and the research world have understood the new goals involved and massively invest around these new technologies, named 'grid'. One of the fields is about calculating. This is the subject of the works presented here. At the Paris Orsay University, a synergy emerged between the Computing Science Laboratory (LRI) and the Linear Accelerator Laboratory (LAL) on grid infrastructure, opening new investigations fields for the first and new high computing perspective for the other. Works presented here are the results of this multi-discipline collaboration. They are based on XtremWeb, the LRI global computing platform. We first introduce a state of the art of the large scale distributed systems, its principles, its architecture based on services. We then introduce XtremWeb and detail modifications and improvements we had to specify and implement to achieve our goals. We present two different studies, first interconnecting grids in order to generalize resource sharing and secondly, be able to use legacy services on such platforms. We finally explain how a research community like the community of high energy cosmic radiation detection can gain access to these services and detail Monte Carlos and data analysis processes over the grids.

    The principal goal in the development of new technologies for environmental monitoring and characterization is transferring them to organizations and individuals for use in site assessment and compliance monitoring. The DOE complex has devised several strategies to facilitate this transfer including joint research projects between private industries and government laboratories or universities (CRADAs), and streamlined licensing procedures. One strategy that has been under-utilized is a planned sequence gradually moving from laboratory development and field demonstration to long term evaluation and onsite use. Industrial partnership and commercial production can be initiated at any step based on the performance, market, user needs, and costs associated with the technology. The Savannah River Technology Center (SRTC) has been developing a program to rigorously field test promising environmental technologies that have not undergone EPA equivalency testing. The infrastructure and staff expertise developed as part of the activities of the Savannah River Integrated Demonstration Program (i.e., wells, available power, conventional baseline characterization and monitoring equipment, shelter structures) allows field testing of technologies without the difficulties of providing remote field support. By providing a well-characterized site and a well-developed infrastructure, technologies can be tested for long periods of time to determine their appropriate applications in environmental characterization and monitoring activities. Situation specific evaluations of the technology following stringent test plans can be made in comparison with simultaneous baseline methods and historical data. This program is designed to help expedite regulatory approval and technology transfer to manufacturers and the user community

    Highlights: • Application of PSO algorithm can improve the accuracy of the baseline model. • M&V cloud platform automatically calculates energy performance. • M&V cloud platform can be applied in all energy conservation measures. • Real-time operational performance can be monitored through the proposed platform. • M&V cloud platform facilitates the development of EE programs and ESCO industries. - Abstract: Nations worldwide are vigorously promoting policies to improve energy efficiency. The use of measurement and verification (M&V) procedures to quantify energy performance is an essential topic in this field. Currently, energy performance M&V is accomplished via a combination of short-term on-site measurements and engineering calculations. This requires extensive amounts of time and labor and can result in a discrepancy between actual energy savings and calculated results. In addition, the M&V period typically lasts for periods as long as several months or up to a year, the failure to immediately detect abnormal energy performance not only decreases energy performance, results in the inability to make timely correction, and misses the best opportunity to adjust or repair equipment and systems. In this study, a cloud computing platform for the real-time M&V of energy performance is developed. On this platform, particle swarm optimization and multivariate regression analysis are used to construct accurate baseline models. Instantaneous and automatic calculations of the energy performance and access to long-term, cumulative information about the energy performance are provided via a feature that allows direct uploads of the energy consumption data. Finally, the feasibility of this real-time M&V cloud platform is tested for a case study involving improvements to a cold storage system in a hypermarket. Cloud computing platform for real-time energy performance M&V is applicable to any industry and energy conservation measure. With the M&V cloud platform, real

    The Arctic Energy Technology Development Laboratory was created by the University of Alaska Fairbanks in response to a congressionally mandated funding opportunity through the U.S. Department of Energy (DOE), specifically to encourage research partnerships between the university, the Alaskan energy industry, and the DOE. The enabling legislation permitted research in a broad variety of topics particularly of interest to Alaska, including providing more efficient and economical electrical power generation in rural villages, as well as research in coal, oil, and gas. The contract was managed as a cooperative research agreement, with active project monitoring and management from the DOE. In the eight years of this partnership, approximately 30 projects were funded and completed. These projects, which were selected using an industry panel of Alaskan energy industry engineers and managers, cover a wide range of topics, such as diesel engine efficiency, fuel cells, coal combustion, methane gas hydrates, heavy oil recovery, and water issues associated with ice road construction in the oil fields of the North Slope. Each project was managed as a separate DOE contract, and the final technical report for each completed project is included with this final report. The intent of this process was to address the energy research needs of Alaska and to develop research capability at the university. As such, the intent from the beginning of this process was to encourage development of partnerships and skills that would permit a transition to direct competitive funding opportunities managed from funding sources. This project has succeeded at both the individual project level and at the institutional development level, as many of the researchers at the university are currently submitting proposals to funding agencies, with some success.

  20. Technology Learning Ratios in Global Energy Models

    International Nuclear Information System (INIS)

    Varela, M.

    2001-01-01

    The process of introduction of a new technology supposes that while its production and utilisation increases, also its operation improves and its investment costs and production decreases. The accumulation of experience and learning of a new technology increase in parallel with the increase of its market share. This process is represented by the technological learning curves and the energy sector is not detached from this process of substitution of old technologies by new ones. The present paper carries out a brief revision of the main energy models that include the technology dynamics (learning). The energy scenarios, developed by global energy models, assume that the characteristics of the technologies are variables with time. But this trend is incorporated in a exogenous way in these energy models, that is to say, it is only a time function. This practice is applied to the cost indicators of the technology such as the specific investment costs or to the efficiency of the energy technologies. In the last years, the new concept of endogenous technological learning has been integrated within these global energy models. This paper examines the concept of technological learning in global energy models. It also analyses the technological dynamics of the energy system including the endogenous modelling of the process of technological progress. Finally, it makes a comparison of several of the most used global energy models (MARKAL, MESSAGE and ERIS) and, more concretely, about the use these models make of the concept of technological learning.

  1. Global energy and technology trends

    International Nuclear Information System (INIS)

    Rogner, Hans-Holger

    2008-01-01

    Economic development translates into growing demand for energy services. However, more than 1.6 billion people at present still do not have access to modern energy services. Continued population growth compounds this demand for energy, which is central to achieving sustainable development goals. Poverty eradication calls for affordable energy services. There is a need to minimize health and environmental impacts of energy use. Nuclear power's share of global electricity rose to 16% in 1986. Near the end of the 1980s growth stagnated. Regulatory interventions often stretched out licensing times and increased costs. Inflation and rising energy costs resulting from the oil shocks of 1973 and 1979 brought about a significant drop in electricity demand and raised the costs of capital intensive power plants, like nuclear power plants. Some utilities found the regulatory and transaction costs of nuclear power simply too high to manage costs-effectively. The 1979 Three Mile Island accident and the Chernobyl accident in 1986 retarded the expansion of nuclear power. The electricity market liberalization and privatization exposed excess capacity, pushed electricity prices lower and made power plant investments more risky. Other things being equal, nuclear power's front-loaded cost structure was a disadvantage in markets that emphasize short term profits and rapid returns. In the 1990s, growth in nuclear electricity generation exceeded the growth in nuclear capacity as management efficiencies and technological advances progressively raised the average energy availability of the world's nuclear plants. The energy availability factor measures the percentage of time that a power reactor is available to generate electricity, rather than being shutdown for refuelling, maintenance and other reasons. The global average for nuclear power reactors has risen from 67% in 1990 to 81% in 2004. This increase is equivalent to the addition of 34 new 1000 MW reactors. Electricity generation

    Utilizing an existing 313 MW(t) ship propulsion reactor design, a concept has been formulated for a floating platform-mounted nuclear plant and an evaluation has been made to determine reductions in construction time and cost achievable by repetitive platform construction in a shipyard. Concepts and estimates are presented for siting platform-mounted nuclear plants at the location of industrial facilities where the nuclear plants would furnish industrial process heat and/or electrical power. The representative industrial site designated for this study is considered typical of sites that might be used along the extensive network of navigable canals adjacent to the ocean and is similar to potential sites along the inland waterways of the United States

  4. Energy Policy is Technology Politics The Hydrogen Energy Case

    2006-01-01

    Germany's energy supply status shows both an accumulation of unsatisfactory sustainabilities putting the nation's energy security at risk, and a hopeful sign: The nation's supply dependency on foreign sources and the accordingly unavoidable price dictate the nation suffers under is almost life risking; the technological skill, however, of the nation's researchers, engineers, and industry materializes in a good percentage of the indigenous and the world's energy conversion technology market. Exemplified with the up and coming hydrogen energy economy this paper tries to advocate the 21. century energy credo: energy policy is energy technology politics! Energy source thinking and acting is 19. and 20. century, energy efficient conversion technology thinking and acting is 21. century. Hydrogen energy is on the verge of becoming the centre-field of world energy interest. Hydrogen energy is key for the de-carbonization and, thus, sustainabilization of fossil fuels, and as a storage and transport means for the introduction of so far un-operational huge renewable sources into the world energy market. - What is most important is hydrogen's thermodynamic ability to exergize the energy scheme: hydrogen makes more technical work (exergy) out of less primary energy! Hydrogen adds value. Hydrogen energy and, in particular, hydrogen energy technologies, are to become part of Germany's national energy identity; accordingly, national energy policy as energy technology politics needs to grow in the nation's awareness as common sense! Otherwise Germany seems ill-equipped energetically, and its well-being hangs in the balance. (author)

    The principal goal in the development of new technologies for environmental monitoring and characterization is transferring them to organizations and individuals for use in site assessment and compliance monitoring. The DOE complex has devised several strategies to facilitate this transfer including joint research projects between private industries and government laboratories or universities (CRADAs) and streamlined licensing procedures. One strategy that has been under-utilized is a planned sequence gradually moving from laboratory development and field demonstration to long term evaluation and onsite use. Industrial partnership and commercial production can be initiated at any step based on the performance, market, user needs, and costs associated with the technology. This approach allows use of the technology by onsite groups for compliance monitoring tasks (e.g. Environmental Restoration and Waste Management), while following parallel research and development organizations the opportunity to evaluate the long term performance and to make modifications or improvements to the technology. This probationary period also provides regulatory organizations, potential industrial partners, and potential users with the opportunity to evaluate the technology's performance and its utility for implementation in environmental characterization and monitoring programs

    2010-05-01

    The Oceanic Platform of the Canary Islands (PLOCAN) is a Governmental Consortium aimed to build and operate an off-shore infrastructure to facilitate the deep sea research and speed up the technology associated. This Consortium is overseen by the Spanish Ministry of Science and Innovation and the Canarian Agency for Research and Innovation. The infrastructure consists of an oceanic platform located in an area with depths between 50-100 meters, close to the continental slope and four kilometers off the coast of Gran Canaria, in the archipelago of the Canary Islands. The process of construction will start during the first months of 2010 and is expected to be finished in mid-year 2011. PLOCAN serves five strategic lines: an integral observatory able to explore from the deep ocean to the atmosphere, an ocean technology testbed, a base for underwater vehicles, an innovation platform and a highly specialized training centre. Ocean energy is a suitable source to contribute the limited mix-energy conformed in the archipelago of the Canary Islands with a total population around 2 million people unequally distributed in seven islands. Islands of Gran Canaria and Tenerife support the 80% of the total population with 800.000 people each. PLOCAN will contribute to develop the ocean energy sector establishing a marine testbed allowing prototypes testing at sea under a meticulous monitoring network provided by the integral observatory, generating valuable information to developers. Reducing costs throughout an integral project management is an essential objective to be reach, providing services such as transportation, customs and administrative permits. Ocean surface for testing activities is around 8 km2 with a depth going from 50 to 100 meters, 4km off the coast. Selected areas for testing have off-shore wind power conditions around 500-600 W/m2 and wave power conditions around 6 kW/m in the East coast and 10 kW/m in the North coast. Marine currents in the Canary Islands are

    Platform technologies (PT) are techniques or tools that enable a range of scientific investigations and are critical to today's advanced technology research environment. Once installed, they require specialized staff for their operations, who in turn, provide expertise to researchers in designing appropriate experiments. Through this pipeline, research outputs are raised to the benefit of the researcher and the host institution. Platform facilities provide access to instrumentation and expertise for a wide range of users beyond the host institution, including other academic and industry users. To maximize the return on these substantial public investments, this wider access needs to be supported. The question of support and the mechanisms through which this occurs need to be established based on a greater understanding of how PT facilities operate. This investigation was aimed at understanding if and how platform facilities across the Bio21 Cluster meet operating costs. Our investigation found: 74% of platforms surveyed do not recover 100% of direct operating costs and are heavily subsidized by their home institution, which has a vested interest in maintaining the technology platform; platform managers play a major role in establishing the costs and pricing of the facility, normally in a collaborative process with a management committee or institutional accountant; and most facilities have a three-tier pricing structure recognizing internal academic, external academic, and commercial clients.

    Scientific and technological progress now occurs at the interface between two or more scientific and technical disciplines while chemistry is intertwined with almost all scientific domains. Complementary and synergistic effects have been found in the overlay between sonochemistry and other enabling technologies such as mechanochemistry, microwave chemistry and flow-chemistry. Although their nature and effects are intrinsically different, these techniques share the ability to significantly activate most chemical processes and peculiar phenomena. These studies offer a comprehensive overview of sonochemistry, provide a better understanding of correlated phenomena (mechanochemical effects, hot spots, etc.), and pave the way for emerging applications which unite hybrid reactors.

    2018-02-01

    Nowadays, a large scale of renewable energy sources has been connecting to power system and the real time simulation platform is widely used to carry out research on integration control algorithm, power system stability etc. Compared to traditional pure digital simulation and hardware in the loop simulation, power in the loop simulation has higher accuracy and degree of reliability. In this paper, a power in the loop analog digital hybrid simulation platform has been built and it can be used not only for the single generation unit connecting to grid, but also for multiple new energy generation units connecting to grid. A wind generator inertia control experiment was carried out on the platform. The structure of the inertia control platform was researched and the results verify that the platform is up to need for renewable power in the loop real time simulation.

    1991-01-01

    Three companies, AME from the UK, Comex from France and Tecnomare from Italy proposed to EC Directorate General for Energy to perform research and development studies of technology for the removal of offshore platforms. At the suggestion of the EC a co-operation was initiated between the three companies and this paper presents a brief outline of the projects and some results from the co-operative work. The results reported included those from a review of the possible removal techniques, the type of structures and the market potential for industry. The specific technologies studied by the individual companies were safe and reliable application of explosive shaped charges to the cutting of large steel jacket tubulars and the effect of underwater shock; establishing the performance of high pressure abrasive water jet cutting by means of extensive testing under hyperbaric conditions; and the design of a driverless underwater cutting system that can be integrated with advanced cutting techniques and provide a commercially viable facility.

    2014-03-01

    Whether in OECD, emerging or developing country economies, governments are increasingly looking to diversify their energy mix beyond simply fossil fuels. While wind energy is developing towards a mainstream, competitive and reliable technology, a range of barriers can delay progress, such as financing, grid integration, social acceptance and aspects of planning processes. National and regional technology roadmaps can play a key role in supporting wind energy development and implementation, helping countries to identify priorities and pathways tailored to local resources and markets. Recognising this, the IEA has started the How2Guides - a new series co-ordinated by the International Low-Carbon Energy Technology Platform to address the need for more focused guidance in the development of national roadmaps, or strategies, for specific low-carbon technologies. This builds on the success of the IEA global technology roadmap series and responds to a growing number of requests for IEA guidance to adapt the findings of the IEA global technology roadmaps to national circumstances. A successful roadmap contains a clear statement of the desired outcome, followed by a specific pathway for reaching it. The How2Guide for Wind Energy builds on the IEA well established methodology for roadmap development and shares wind specific recommendations on how to address the four phases to developing and implementing a wind energy roadmap: Planning; Visioning; Development; and Implementation. The manual also offers menus of recommendations on policy and technical options for deployment of utility-scale wind energy installations. A matrix of barriers-versus-realistic solutions options is cross-listed with considerations such as planning, development, electricity market and system, infrastructure, and finance and economics. Drawing on several case studies from around the globe, as well as on the IEA Technology Roadmap for Wind Energy, the How2Guide for Wind Energy it is intended as a

    2001-01-01

    For this study, we identified about 175 emerging energy-efficient technologies in industry, of which we characterized 54 in detail. While many profiles of individual emerging technologies are available, few reports have attempted to impose a standardized approach to the evaluation of the technologies. This study provides a way to review technologies in an independent manner, based on information on energy savings, economic, non-energy benefits, major market barriers, likelihood of success, and suggested next steps to accelerate deployment of each of the analyzed technologies. There are many interesting lessons to be learned from further investigation of technologies identified in our preliminary screening analysis. The detailed assessments of the 54 technologies are useful to evaluate claims made by developers, as well as to evaluate market potentials for the United States or specific regions. In this report we show that many new technologies are ready to enter the market place, or are currently under development, demonstrating that the United States is not running out of technologies to improve energy efficiency and economic and environmental performance, and will not run out in the future. The study shows that many of the technologies have important non-energy benefits, ranging from reduced environmental impact to improved productivity. Several technologies have reduced capital costs compared to the current technology used by those industries. Non-energy benefits such as these are frequently a motivating factor in bringing technologies such as these to market. Further evaluation of the profiled technologies is still needed. In particular, further quantifying the non-energy benefits based on the experience from technology users in the field is important. Interactive effects and inter-technology competition have not been accounted for and ideally should be included in any type of integrated technology scenario, for it may help to better evaluate market

    U.S. industry consumes approximately 37 percent of the nation's energy to produce 24 percent of the nation's GDP. Increasingly, industry is confronted with the challenge of moving toward a cleaner, more sustainable path of production and consumption, while increasing global competitiveness. Technology will be essential for meeting these challenges. At some point, businesses are faced with investment in new capital stock. At this decision point, new and emerging technologies compete for capital investment alongside more established or mature technologies. Understanding the dynamics of the decision-making process is important to perceive what drives technology change and the overall effect on industrial energy use. The assessment of emerging energy-efficient industrial technologies can be useful for: (1) identifying R&D projects; (2) identifying potential technologies for market transformation activities; (3) providing common information on technologies to a broad audience of policy-makers; and (4) offering new insights into technology development and energy efficiency potentials. With the support of PG&E Co., NYSERDA, DOE, EPA, NEEA, and the Iowa Energy Center, staff from LBNL and ACEEE produced this assessment of emerging energy-efficient industrial technologies. The goal was to collect information on a broad array of potentially significant emerging energy-efficient industrial technologies and carefully characterize a sub-group of approximately 50 key technologies. Our use of the term ''emerging'' denotes technologies that are both pre-commercial but near commercialization, and technologies that have already entered the market but have less than 5 percent of current market share. We also have chosen technologies that are energy-efficient (i.e., use less energy than existing technologies and practices to produce the same product), and may have additional ''non-energy benefits.'' These benefits are as important (if

    2017-08-01

    Publications describing microplasmas, which are commonly defined as plasmas with at least one dimension in the submillimeter range, began to appear to the scientific literature about 20 years ago. As discussed in a recent review by Schoenbach and Becker [1], interest and activities in basic microplasma research as well as in the use of microplasma for a variety of application has increased significatly over the past 20 years. The number of papers devoted to basic microplasma science increased by an order of magnitude between 1995 and 2015, a count that excludes publications dealing exclusively with technological applications of microplasmas, where the microplasma is used solely as a tool. In reference [1], the authors limited the topical coverage largely to the status of microplasma science and our understanding of the physics principles that enable microplasma operation and further stated that the rapid proliferation of microplasma applications made it impossible to cover both basic microplasma science and their application in a single review article.

    The human body contains approximately 10 14 cells, wherein each one is a nucleus. The nucleus contains 2x23 chromosomes, or two complete sets of the human genome, one set coming from the mother and the other from the father. In principle each set includes 30.000-40.000 genes. If the genome was a book, it would be twenty-three chapters, called chromosomes,each chapter with several thousand stories, called genes. Each story made up of paragraphs, called exons and introns. Each paragraph made up of 3 letter words, called codons. Each word is written with letters called bases (AGCT). But the whole is written in a single very long sentence, which is the DNA molecule or deoxy nucleic acid. The usual state of DNA is two complementary strands intertwined forming a double helix. In the cell, DNA is duplicated during each cell division to ensure the transmission of the genome to the daughter cells. For expression, the DNA is transcribed to messenger RNA. The RNA is edited and finally translated to a protein, each three bases coding for one amino acid. When the whole message is translated, the chain of amino acids folds itself up into a distinctive shape that depends on its sequence. Proteins are the effectors of the genes, and are responsible for all metabolic, hormonal and enzymatic reactions in the cells. The expressed RNA determines the amount of proteins to be produced and subsequently the desired effect (strong or weak) in the cell. The microarray technology aims at quantifying the amount of RNA present in the cell from each expressed gene, and at evaluating the changes of these amounts after exposure of the cell to toxic chemicals, ionising radiation or other stress components. The global picture of expressed genes helps to understand the affected genetic pathways in the cell at the molecular level. The microarray technology is used in the Radiobiology and Microbiology topics to study the effect of ionising radiation on human cells and mouse tissue, as well as the

    Deep offshore ocean energy mapping requires detailed modeling of the wind, wave, tidal and ocean circulation estimations. It requires also detailed mapping of the associated extremes. An important issue in such work is the co-generation of energy (generation of wind, wave, tides, currents) in order to design platforms on an efficient way. For example wind and wave fields exhibit significant phase differences and therefore the produced energy from both sources together requires special analysis. The other two sources namely tides and currents have different temporal scales from the previous two. Another important issue is related to the estimation of the environmental frequencies in order to avoid structural problems. These are issues studied at the framework of the FP7 project MARINA PLATFORM. The main objective of the project is to develop deep water structures that can exploit the energy from wind, wave, tidal and ocean current energy sources. In particular, a primary goal will be the establishment of a set of equitable and transparent criteria for the evaluation of multi-purpose platforms for marine renewable energy. Using these criteria, a novel system set of design and optimisation tools will be produced addressing new platform design, component engineering, risk assessment, spatial planning, platform-related grid connection concepts, all focussed on system integration and reducing costs. The University of Athens group is in charge for estimation and mapping of wind, wave, tidal and ocean current resources, estimate available energy potential, map extreme event characteristics and provide any additional environmental parameter required.

    Despite various policies, renewable energy resources have not been developed in Malaysia. This study investigates the factors that influence renewable energy technology acceptance in Peninsular Malaysia and attempts to show the impact of cost and knowledge on the perceived ease of use and perceived usefulness of renewable energy technology. The results show that cost of renewable energy has an indirect effect on attitudes towards using renewable energy through the associated impact on the perceived ease of use and perceived usefulness. The results also indicate that public knowledge in Peninsular Malaysia does not affect perceived ease of use, although the positive impact of knowledge on perceived usefulness is supported. Furthermore, our results show that the current business environment in Peninsular Malaysia does not support the adoption of renewable energy technology, and thus, renewable energy technology is not commercially viable in Peninsular Malaysia. Additionally, the population of Peninsular Malaysia associates the use of renewable energy with a high level of effort and therefore has a negative attitude towards the use of renewable energy technology. There is, therefore, a definite need to pay more attention to the role of public perception and awareness in the successes and failures of renewable energy policy. - Highlights: • Public acceptance is an essential element in the diffusion of renewable energy. • Perceived ease of use and perceived usefulness affect intention to use renewables. • It is important to reduce the cost of renewable energy, particularly for end users. • Renewable energy policies should address issues of public perception and awareness.

    The distortion of the collected images usually takes place since the attitude changes along with the flying aerocraft on airborne remote sensing. In order to get original images without distortion, it is necessary to use professional gyro-stabilized platform. In addition to this, another solution of correcting the original image distortion is to utilize later geometric rectification using position & orientation system ( POS ) data. The third way is to utilize medium-accuracy stabilized platform to control the distortion at a tolerant range, and then make use of the data obtained by high-solution posture measure system to correct the low-quality remote sensing images. The third way which takes advantage of both techniques is better than using only one of the two other ways. This paper introduces several kinds of structural forms of gyro-stabilized platforms, and POS acquiring instruments respectively. Then, the essay will make some analysis of their advantages and disadvantages, key technologies and the application experiment of the third method. After the analysis, the thesis discusses the design of the gyro-stabilized platform. The thesis provides crucial information not only for the application technology of gyro-stabilized platform and POS but also for future development.

Therefore, development of the effective way of energy usage and energy resources of low pollution is needed. Development of the energy conversion technology by chemical processes is also indispensable, which will replace the pollutant-producing and inefficient mechanical energy conversion technologies. Energy conversion technology by chemical processes directly converts chemical energy to electrical one, or converts heat energy to chemical one followed by heat storage. The technology includes batteries, fuel cells, and energy storage system. The are still many problems on performance, safety, and manufacturing of the secondary battery which is highly demanded in electronics, communication, and computer industries. To overcome these problems, key components such as carbon electrode, metal oxide electrode, and solid polymer electrolyte are developed in this study, followed by the fabrication of the lithium secondary battery. Polymer electrolyte fuel cell, as an advanced power generating apparatus with high efficiency, no pollution, and no noise, has many applications such as zero-emission vehicles, on-site power plants, and military purposes. After fabricating the cell components and operating the single cells, the fundamental technologies in polymer electrolyte fuel cell are established in this study. Energy storage technology provides the safe and regular heat energy, irrespective of the change of the heat energy sources, adjusts time gap between consumption and supply, and upgrades and concentrates low grade heat energy. In this study, useful chemical reactions for efficient storage and transport are investigated and the chemical heat storage technology are developed. (author) 41 refs., 90 figs., 20 tabs.

Especially distinguished wind energy, both in view of the installed power and a global technology sales. Public funding for energy research has experienced a significant decline since the oil crisis of the 1970s, although the figures in recent years has increased a bit. According to the IEA, it will require a significant increase in funding to reduce greenhouse gas emissions and limit further climate change. The third point highlighted in the report is the importance of international cooperation in energy research. Nordic and international cooperation is necessary in order to reduce duplication and create the synergy needed if we are to achieve our ambitious policy objectives in the climate and energy issue.

    This state-of-science review sets out to provide an indicative assessment of enabling technologies for reducing UK industrial energy demand and carbon emissions to 2050. In the short term, i.e. the period that will rely on current or existing technologies, the road map and priorities are clear. A variety of available technologies will lead to energy demand reduction in industrial processes, boiler operation, compressed air usage, electric motor efficiency, heating and lighting, and ancillary uses such as transport. The prospects for the commercial exploitation of innovative technologies by the middle of the 21st century are more speculative. Emphasis is therefore placed on the range of technology assessment methods that are likely to provide policy makers with a guide to progress in the development of high-temperature processes, improved materials, process integration and intensification, and improved industrial process control and monitoring. Key among the appraisal methods applicable to the energy sector is thermodynamic analysis, making use of energy, exergy and 'exergoeconomic' techniques. Technical and economic barriers will limit the improvement potential to perhaps a 30% cut in industrial energy use, which would make a significant contribution to reducing energy demand and carbon emissions in UK industry. Non-technological drivers for, and barriers to, the take-up of innovative, low-carbon energy technologies for industry are also outlined

    Techniques to incorporate the concepts of profit-induced growth and risk aversion into policy-oriented optimization models of the domestic energy sector are examined. After reviewing the pertinent market penetration literature, simple mathematical programs in which the introduction of new energy technologies is constrained primarily by the reinvestment of profits are formulated. The main results involve the convergence behavior of technology production levels under various assumptions about the form of the energy demand function. Next, profitability growth constraints are embedded in a full-scale model of U.S. energy-economy interactions. A rapidly convergent algorithm is developed to utilize optimal shadow prices in the computation of profitability for individual technologies. Allowance is made for additional policy variables such as government funding and taxation. The result is an optimal deployment schedule for current and future energy technologies which is consistent with the sector's ability to finance capacity expansion.

    Advanced energy technologies span a wide variety of resources, techniques, and end-user requirements. Economic considerations are major factors that shape their harnessing and utilization. A discussion of the basic factors in the economic arena is presented, with particular emphasis on renewable energy technologies--photovoltaics, solar-thermal, wind-electric conversion, biomass utilization, hydro, and tidal and wave energy systems. The following are essential to determine appropriate energy system topologies: proper resource-need matching with an eye on the quality of energy requirements, integrated use of several resources and technologies, and a comprehensive consideration which includes prospecting, collection, conversion, transportation, distribution, storage and reconversion, end use, and subsequent waste management aspects. A few case studies are included to apprise the reader of the status of some of the key technologies and systems

    Immersive virtual reality (VR) and virtual worlds (VWs) are an emerging set of technologies which likely represent the next evolutionary step in the ways we use information technology to interact with the world of information and with other people, the roles now generally fulfilled by the Web and other common Internet applications. Currently, these technologies are mainly accessed through various VWs, e.g., the Second Life (SL), which are general platforms for a broad range of user activities. As an experiment in the utilization of these technologies for science, scholarship, education, and public outreach, we have formed the Meta-Institute for Computational Astrophysics (MICA; http://mica-vw.org), the first professional scientific organization based exclusively in VWs. The goals of MICA are: (1) Exploration, development and promotion of VWs and VR technologies for professional research in astronomy and related fields. (2) Providing and developing novel social networking venues and mechanisms for scientific collaboration and communications, including professional meetings, effective telepresence, etc. (3) Use of VWs and VR technologies for education and public outreach. (4) Exchange of ideas and joint efforts with other scientific disciplines in promoting these goals for science and scholarship in general. To this effect, we have a regular schedule of professional and public outreach events in SL, including technical seminars, workshops, journal club, collaboration meetings, public lectures, etc. We find that these technologies are already remarkably effective as a telepresence platform for scientific and scholarly discussions, meetings, etc. They can offer substantial savings of time and resources, and eliminate a lot of unnecessary travel. They are equally effective as a public outreach platform, reaching a world-wide audience. On the pure research front, we are currently exploring the use of these technologies as a venue for numerical simulations and their

    Full Text Available The high performance computing community has traditionally focused uniquely on the reduction of execution time, though in the last years, the optimization of energy consumption has become a main issue. A reduction of energy usage without a degradation of performance requires the adoption of energy-efficient hardware platforms accompanied by the development of energy-aware algorithms and computational kernels. The solution of linear systems is a key operation for many scientific and engineering problems. Its relevance has motivated an important amount of work, and consequently, it is possible to find high performance solvers for a wide variety of hardware platforms. In this work, we aim to develop a high performance and energy-efficient linear system solver. In particular, we develop two solvers for a low-power CPU-GPU platform, the NVIDIA Jetson TK1. These solvers implement the Gauss-Huard algorithm yielding an efficient usage of the target hardware as well as an efficient memory access. The experimental evaluation shows that the novel proposal reports important savings in both time and energy-consumption when compared with the state-of-the-art solvers of the platform.

    2012-01-01

    Full Text Available Photovoltaic power plants as a renewable energy source have been receiving rapidly growing attention in the Czech Republic and in the other EU countries. This rapid development of photovoltaic sources is having a negative effect on the electricity power system control, because they depend on the weather conditions and provide a variable and unreliable supply of electric power. One way to reduce this effect is by accumulating electricity in hydrogen. The aim of this paper is to introduce hydrogen as a tool for regulating photovoltaic energy in island mode. A configuration has been designed for connecting households with the photovoltaic hybrid system, and a simulation model has been made in order to check the validity of this system. The simulation results provide energy flows and have been used for optimal sizing of real devices. An appropriate system can deliver energy in a stand-alone installation.

    HNEI has conducted research to address a number of issues important to move Hawai‘i to greater use of intermittent renewable and distributed energy resource (DER) technologies in order to facilitate greater use of Hawai‘i's indigenous renewable energy resources. Efforts have been concentrated on the Islands of Hawai‘i, Maui, and O‘ahu, focusing in three areas of endeavor: 1) Energy Modeling and Scenario Analysis (previously called Energy Road mapping); 2) Research, Development, and Validation of Renewable DER and Microgrid Technologies; and 3) Analysis and Policy. These efforts focused on analysis of the island energy systems and development of specific candidate technologies for future insertion into an integrated energy system, which would lead to a more robust transmission and distribution system in the state of Hawai‘i and eventually elsewhere in the nation.

    As the contribution of electricity generated from renewable sources (wind, wave and solar) grows, the inherent intermittency of supply from such generating technologies must be addressed by a step-change in energy storage. Furthermore, the continuously developing demands of contemporary applications require the design of versatile energy-storage/power supply systems offering wide ranges of power density and energy density. As no single energy-storage technology has this capability, systems will comprise combinations of technologies such as electrochemical supercapacitors, flow batteries, lithium-ion batteries, superconducting magnetic energy storage (SMES) and kinetic energy storage. The evolution of the electrochemical supercapacitor is largely dependent on the development of optimised electrode materials (tailored to the chosen electrolyte) and electrolytes. Similarly, the development of lithium-ion battery technology requires fundamental research in materials science aimed at delivering new electrodes and electrolytes. Lithium-ion technology has significant potential, and a step-change is required in order to promote the technology from the portable electronics market into high-duty applications. Flow-battery development is largely concerned with safety and operability. However, opportunities exist to improve electrode technology yielding larger power densities. The main barriers to overcome with regard to the development of SMES technology are those related to high-temperature superconductors in terms of their granular, anisotropic nature. Materials development is essential for the successful evolution of flywheel technology. Given the appropriate research effort, the key scientific advances required in order to successfully develop energy-storage technologies generally represent realistic goals that may be achieved by 2050

    Conservation supply curves are a common tool in economic analysis. As such, they provide an important opportunity to include a non-linear representation of technology and technological change in economy-wide models. Because supply curves are closely related to production isoquants, we explore the possibility of using bottom-up technology assessments to inform top-down representations of energy models of the U.S. economy. Based on a recent report by LBNL and ACEEE on emerging industrial technologies within the United States, we have constructed a supply curve for 54 such technologies for the year 2015. Each of the selected technologies has been assessed with respect to energy efficiency characteristics, likely energy savings by 2015, economics, and environmental performance, as well as needs for further development or implementation of the technology. The technical potential for primary energy savings of the 54 identified technologies is equal to 3.54 Quads, or 8.4 percent of the assume d2015 industrial energy consumption. Based on the supply curve, assuming a discount rate of 15 percent and 2015 prices as forecasted in the Annual Energy Outlook2002, we estimate the economic potential to be 2.66 Quads - or 6.3 percent of the assumed forecast consumption for 2015. In addition, we further estimate how much these industrial technologies might contribute to standard reference case projections, and how much additional energy savings might be available assuming a different mix of policies and incentives. Finally, we review the prospects for integrating the findings of this and similar studies into standard economic models. Although further work needs to be completed to provide the necessary link between supply curves and production isoquants, it is hoped that this link will be a useful starting point for discussion with developers of energy-economic models.

    Electrochemical cells and systems play a key role in a wide range of industry sectors. These devices are critical enabling technologies for renewable energy; energy management, conservation, and storage; pollution control/monitoring; and greenhouse gas reduction. A large number of electrochemical energy technologies have been developed in the past. These systems continue to be optimized in terms of cost, life time, and performance, leading to their continued expansion into existing and emerging market sectors. The more established technologies such as deep-cycle batteries and sensors are being joined by emerging technologies such as fuel cells, large format lithium-ion batteries, electrochemical reactors; ion transport membranes and supercapacitors. This growing demand (multi billion dollars) for electrochemical energy systems along with the increasing maturity of a number of technologies is having a significant effect on the global research and development effort which is increasing in both in size and depth. A number of new technologies, which will have substantial impact on the environment and the way we produce and utilize energy, are under development. This paper presents an overview of several emerging electrochemical energy technologies along with a discussion some of the key technical challenges. PMID:25309898

  20. Energy technology and American democratic values

    1988-01-01

    Today, the benefits of liberal democracy have increasingly been cast into doubt. The debate over alternative energy policies illustrates the problems associated with liberal democracy. For many, it is the realization that energy choices and the selection of social and political values amount to much the same thing. Simply put, energy policy decisions, and the concomitant energy technologies, carry implications of an ethical, social and political nature. The argument of the social and political effects of energy technology flows from the more general thesis that all forms of technological practice condition social and political relations. That is, technological systems, beyond performing the specific functions for which they were designed, act upon and influence social and political arrangements. Seen in this light, energy technologies are as important to the promotion and preservation of this country's political values as are its institutions and laws. Further, there is evidence to suggest that this country's cherished democratic value of freedom is slowly being eclipsed by the values attendant to corporate capitalism and its singular pursuit of growth. It is this dominance of economic values over political values which provides the environment within which the technological debate is waged. Ultimately, tracing the historic linkage between property and liberty, it is concluded that the preservation of our freedom require new thinking regarding the present configuration of ownership patterns. The questions surrounding energy policy serve to illuminate these concerns.

    With attention now focused on the damaging impact of greenhouse gases, wind energy is rapidly emerging as a low carbon, resource efficient, cost-effective sustainable technology in many parts of the world. Despite higher economic costs, offshore appears to be the next big step in wind energy development alternative because of the space scarcity for installation of onshore wind turbine. This paper presents the importance of off-shore wind energy, the wind farm layout design, the off-shore wind turbine technological developments, the role of sensors and the smart grid, and the challenges and future trends of wind energy.

    Technology development requires an enormous financial investment over a long period of time. Scarce national and corporate resources, the result of highly competitive markets, decreased profit margins, wide currency fluctuations, and growing debt, often preclude continuous development of energy technology by single entities, i.e., corporations, institutions, or nations. Although the energy needs of the developed world are generally being met by existing institutions, it is becoming increasingly clear that existing capital formation and technology transfer structures have failed to aid developing nations in meeting their growing electricity needs. This paper will describe a method for meeting the electricity needs of the developing world through technology transfer and international cooperative technology development. The role of nuclear power and the advanced passive plant design will be discussed. (author)

    Platform technologies for the changing need of diagnostics are one of the main challenges in medical device technology. From one point-of-view the demand for new and more versatile diagnostic is increasing due to a deeper knowledge of biomarkers and their combination with diseases. From another point-of-view a decentralization of diagnostics will occur since decisions can be made faster resulting in higher success of therapy. Hence, new types of technologies have to be established which enables a multiparameter analysis at the point-of-care. Within this review-like article a system called Fraunhofer ivD-platform is introduced. It consists of a credit-card sized cartridge with integrated reagents, sensors and pumps and a read-out/processing unit. Within the cartridge the assay runs fully automated within 15-20 minutes. Due to the open design of the platform different analyses such as antibody, serological or DNA-assays can be performed. Specific examples of these three different assay types are given to show the broad applicability of the system.

    In regard to the research and development for fusion energy technologies which are still in the stage of demonstrating scientific availability, it is necessary to accumulate the demonstrations of economic and environmental availability through the demonstration of technological availability. The purpose of this report is to examine how the society can utilize the new fusion energy technology. The technical characteristics of fusion energy system were analyzed in two aspects, namely the production techniques of thermal energy and electric energy. Also on the social characteristics in the fuel cycle stage of fusion reactors, the comparative analysis with existing fission reactors was carried out. Then, prediction and evaluation were made what change of social cycle fusion power generation causes on the social system formalized as a socio-ecological model. Moreover, the restricting factors to be the institutional obstacles to the application of fusion energy system to the society were analyzed from three levels of the decision making on energy policy. Since the convertor of fusion energy system is steam power generation system similar to existing system, the contents and properties of the social cycle change in the American society to which such new energy technology is applied are not much different even if the conversion will be made in future.

    Technical change is a key factor in the energy world. Failure to recognize the potential for technical change, and the pace at which it may occur, has limited the accuracy and usefulness of past energy projections. conversely, programs to develop and deploy advanced energy technologies have often proved disappointing in the face of technical and commercial obstacles. This book examines important new and emerging energy technologies, and the mechanisms by which they may develop and enter the market. The project concentrates on the potential and probable role of selected energy technologies-which are in existence and likely to be of rapidly growing importance over the next decade-and the way in which market conditions and policy environment may affect their implementation

    Energy managers in public agencies are subject to multiple and sometimes conflicting policy objectives regarding cost, environmental, and security concerns associated with alternative energy technologies. Making infrastructure investment decisions requires balancing different distributions of risks and benefits that are far from clear. For example, managers at permanent Army installations must incorporate Congressional legislative objectives, executive orders, Department of Defense directives, state laws and regulations, local restrictions, and multiple stakeholder concerns when undertaking new energy initiatives. Moreover, uncertainty with regard to alternative energy technologies is typically much greater than that associated with traditional technologies, both because the technologies themselves are continuously evolving and because the intermittent nature of many renewable technologies makes a certain level of uncertainty irreducible. This paper describes a novel stochastic multi-attribute analytic approach that allows users to explore different priorities or weighting schemes in combination with uncertainties related to technology performance. To illustrate the utility of this approach for understanding conflicting policy or stakeholder perspectives, prioritizing the need for more information, and making investment decisions, we apply this approach to an energy technology decision problem representative of a permanent military base. Highlights: ► Incorporate disparate criteria with uncertain performance. ► Analyze decisions with contrasting stakeholder positions. ► Interactively compare alternatives based on uncertain weighting. ► User friendly multi-criteria decision analysis (MCDA) tool.

    This book originated in the training courses for teachers of grammar- and secondary schools in Dillingen (Bavaria). The aim of these courses is to become informed about the latest state in one field of physics. The lectures are well-known experts in the respective fields. In the latest study (1980) of the National Academy of Sciences the experts came to the conclusion that without further development nuclear power plants the utilization of too much coal would become necessary and involve irreversible environmental damage (see chapter 6). There are two important obstacles impeding the further extension of nuclear energy. The first problem to be solved is the processing and storage of radioactive waste. This is a more technical task and can be treated in a satisfactory way. The second obstacle is less easy to take as the population has to be convinced that a nuclear power plant can be operated with almost unbelievable safety (see chapter 5) and be shut down safely in the case of incidents. The most promising possibility of controlled nuclear fusion as energy source is still many decades- if feasible at all- away from being performed (see chapter. 7). In the Soviet Union 25% of the electric energy production shall be proceed from nuclear power plants by the year 1990. (orig./GL) [de

    Solar PV power is a commercially available and reliable technology with a significant potential for long-term growth in nearly all world regions. This roadmap estimates that by 2050, PV will provide around 11% of global electricity production and avoid 2.3 gigatonnes (Gt) of CO2 emissions per year. Achieving this roadmap's vision will require an effective, long-term and balanced policy effort in the next decade to allow for optimal technology progress, cost reduction and ramp-up of industrial manufacturing for mass deployment. Governments will need to provide long-term targets and supporting policies to build confidence for investments in manufacturing capacity and deployment of PV systems. PV will achieve grid parity -- i.e. competitiveness with electricity grid retail prices -- by 2020 in many regions. As grid parity is achieved, the policy framework should evolve towards fostering self-sustained markets, with the progressive phase-out of economic incentives, but maintaining grid access guarantees and sustained R&D support.

Achieving this roadmap's vision will require an effective, long-term and balanced policy effort in the next decade to allow for optimal technology progress, cost reduction and ramp-up of industrial manufacturing for mass deployment. Governments will need to provide long-term targets and supporting policies to build confidence for investments in manufacturing capacity and deployment of PV systems. PV will achieve grid parity -- i.e. competitiveness with electricity grid retail prices -- by 2020 in many regions. As grid parity is achieved, the policy framework should evolve towards fostering self-sustained markets, with the progressive phase-out of economic incentives, but maintaining grid access guarantees and sustained R&D support.

    On behalf of the Swedish Energy Agency, SP has investigated and recommended how one could form a platform for demonstration of single family houses as nearly zero energy houses. SP suggests that TMF, the national trade and employers' association of the wood processing and furniture industry in Sweden, should administrate this platform. The reason being that members of TMF produce almost 80% of all single family houses in Sweden. TMF also has the capacity to launch a demonstration platform in a reasonable short time. SP has also compiled a set on technical criteria regarding properties related to energy use that should be met by demonstration projects within the platform. One presumption has been that a house that meets the criteria in the south of Sweden also should meet the criteria in the north of Sweden. The reason being to promote an industrialized and cost effective building process. Another ambition has been not to disfavor smaller single family houses. The main criteria are on very energy efficient building envelopes and very efficient building services systems. The criteria are therefore more detailed than the current Swedish building regulations

    The global energy sector is going through major changes: the need for energy is growing explosively, while at the same time climate change is forcing US to find new, and cleaner, ways to generate energy. Finland is one of the forerunners in energy technology development, partly because of its northern location and partly thanks to efficient innovations. A network of centres of expertise was established in Finland in 1994 to boost the competitiveness and internationalisation of Finnish industry and, consequently, that of the EU region. During the expertise centre programme period 2007-2013, substantial resources will be allocated to efficient utilisation of top level expertise in thirteen selected clusters of expertise. The energy cluster, focusing on developing energy technologies for the future, is one of these

    As dementia, including Alzheimer's disease is a major public health issue worldwide, there are many efforts at European level to promote active and healthy ageing. University of Pecs joined the ICT4Life project - supported by the European Union H2020 programme - in 2016. The aim of this three-years project is to improve qualityof- life and autonomy of patients with mild or moderate dementia with developing a new Information and Communication Technology (ICT) platform, which may provide help for patients, caregivers and professionals. The ICT4Life research is conducted among patients with cognitive decline, their relatives, caregivers, and professionals involved in their care. The needs of the different actors are assessed with semi-structured interviews and clinical scales (cognitive and affective scales, quality-of-life measurements, functionality, caregiver burden), which help to develop a user-friendly, adaptive and personalized platform. Using the integrated ICT platform (bio-sensors, smart TV, tablet, mobile, bracelet) may contribute to monitor (physical, psycho-motor and emotional states) elderly with cognitive decline and to provide better and personalized care for them. The platform includes cognitive enhancement with gamification, and focuses also on the decrease of professional and caregiver burden. Here we report on the ICT4Life programme, which develops an ICT solution for individuals with early stage cognitive impairment while contributing in a user-friendly way to extending their independence and improve their quality-of-life.

  20. Evaluating Internal Technological Capabilities in Energy Companies

    Directory of Open Access Journals (Sweden)

    Mingook Lee

    2016-03-01

    Full Text Available As global competition increases, technological capability must be evaluated objectively as one of the most important factors for predominance in technological competition and to ensure sustainable business excellence. Most existing capability evaluation models utilize either quantitative methods, such as patent analysis, or qualitative methods, such as expert panels. Accordingly, they may be in danger of reflecting only fragmentary aspects of technological capabilities, and produce inconsistent results when different models are used. To solve these problems, this paper proposes a comprehensive framework for evaluating technological capabilities in energy companies by considering the complex properties of technological knowledge. For this purpose, we first explored various factors affecting technological capabilities and divided the factors into three categories: individual, organizational, and technology competitiveness. Second, we identified appropriate evaluation items for each category to measure the technological capability. Finally, by using a hybrid approach of qualitative and quantitative methods, we developed an evaluation method for each item and suggested a method to combine the results. The proposed framework was then verified with an energy generation and supply company to investigate its practicality. As one of the earliest attempts to evaluate multi-faceted technological capabilities, the suggested model can support technology and strategic planning.

    We consider investment in wind, solar photovoltaic, geothermal, and electricity from biomass and waste across 26 OECD countries from 1991 to 2004. Using the PATSTAT database, we obtain a comprehensive list of patents for each of these technologies throughout the world, which we use to assess the impact of technological change on investment in renewable energy capacity. We consider four alternative methods for counting patents, using two possible filters: weighting patents by patent family size and including only patent applications filed in multiple countries. For each patent count, we create knowledge stocks representing the global technological frontier. We find that technological advances do lead to greater investment, but the effect is small. Investments in other carbon-free energy sources, such as hydropower and nuclear power, serve as substitutes for renewable energy. Comparing the effectiveness of our four patent counts, we find that both using only patents filed in multiple countries and weighting by family size improve the fit of the model.

    Renewable energy is an energy which is freely available in nature such as winds and solar energy. It plays a critical role in greening the energy sector as these sources of energy produce little or no pollution to environment. This paper will focus on capability of renewable energy (wind and solar) in generating power for offshore application. Data of wind speeds and solar irradiation that are available around SHELL Sabah Water Platform for every 10 minutes, 24 hours a day, for a period of one year are provided by SHELL Sarawak Sdn. Bhd. The suitable wind turbine and photovoltaic panel that are able to give a high output and higher reliability during operation period are selected by using the tabulated data. The highest power output generated using single wind energy application is equal to 492 kW while for solar energy application is equal to 20 kW. Using the calculated data, the feasibility of renewable energy is then determined based on the platform energy demand. (paper)

    A summary of directed-energy process technology for solar cells was presented. This technology is defined as directing energy or mass to specific areas on solar cells to produce a desired effect in contrast to exposing a cell to a thermal or mass flow environment. Some of these second generation processing techniques are: ion implantation; microwave-enhanced chemical vapor deposition; rapid thermal processing; and the use of lasers for cutting, assisting in metallization, assisting in deposition, and drive-in of liquid dopants. Advantages of directed energy techniques are: surface heating resulting in the bulk of the cell material being cooler and unchanged; better process control yields; better junction profiles, junction depths, and metal sintering; lower energy consumption during processing and smaller factory space requirements. These advantages should result in higher-efficiency cells at lower costs. The results of the numerous contracted efforts were presented as well as the application potentials of these new technologies.

  9. Electric energy storage - Overview of technologies

    International Nuclear Information System (INIS)

    Boye, Henri

    2013-01-01

    Energy storage is a challenging and costly process, as electricity can only be stored by conversion into other forms of energy (e.g. potential, thermal, chemical or magnetic energy). The grids must be precisely balanced in real time and it must be made sure that the cost of electricity is the lowest possible. Storage of electricity has many advantages, in centralized mass storages used for the management of the transmission network, or in decentralized storages of smaller dimensions. This article presents an overview of the storage technologies: mechanical storage in hydroelectric and pumped storage power stations, compressed air energy storage (CAES), flywheels accumulating kinetic energy, electrochemical batteries with various technologies, traditional lead acid batteries, lithium ion, sodium sulfur (NaS) and others, including vehicle to grid, sensible heat thermal storage, superconducting magnetic energy storage (SMES), super-capacitors, conversion into hydrogen... The different technologies are compared in terms of cost and level of maturity. The development of intermittent renewable energies will result in a growing need for mechanisms to regulate energy flow and innovative energy storage solutions seem well positioned to develop.

  10. Soft energy technology hope or illusion

    International Nuclear Information System (INIS)

    Seifritz, W.

    1980-01-01

    Both in the press and in TV, increasingly more voices are calling to turn away from large technology, especially to do without nuclear energy. Well-known representatives of this movement are A. Lovins in the USA, R. Jungk and K. Traube in the Federal Republic of Germany. They make attempts to convince the public that the future problems of energy supply can be solved by saving energy and utilizing alternative energy sources such as solar energy and wind energy. They fight against the 'hard' technology and its main representatives, the large industry because these, in their opinion, desise growth and material wealth at the cost of a healthy environment thus causing a progressing intellectual, cultural, and emotional impoverishment of mankind. Instead of these, they want to use a 'smooth' technology which is thought to lead to a deceuhalisation with more humanity, liberality, and justice. The author shows here that, as far as the potential and the effects of a utilization of alternative energy sources are concerned, these people wake expectations which cannot be fulfilled for technical reasons. But there is something even worse: These utopic expectations lead to an ideology which might result in destroying the fundaments of utilizing the doubtlessly existing potential of the alternative energy sources, especially the often praised renewability of solar energy utilization.

  11. Life cycle emissions from renewable energy technologies

    Bates, J.; Watkiss, P.; Thorpe, T.

    1997-01-01

    This paper presents the methodology used in the ETSU review, together with the detailed results for three of the technologies studied: wind turbines, photovoltaic systems and small, stand-alone solar thermal systems. These emissions are then compared with those calculated for both other renewables and fossil fuel technology on a similar life cycle basis. The life cycle emissions associated with renewable energy technology vary considerably. They are lowest for those technologies where the renewable resource has been concentrated in some way (e.g. over distance in the case of wind and hydro, or over time in the case of energy crops). Wind turbines have amongst the lowest emissions of all renewables and are lower than those for fossil fuel generation, often by over an order of magnitude. Photovoltaics and solar thermal systems have the highest life cycle emissions of all the renewable energy technologies under review. However, their emissions of most pollutants are also much lower than those associated with fossil fuel technologies. In addition, the emissions associated with PV are likely to fall further in the future as the conversion efficiency of PV cells increases and manufacturing technology switches to thin film technologies, which are less energy intensive. Combining the assessments of life cycle emissions of renewables with predictions made by the World Energy Council (WEC) of their future deployment has allowed estimates to be made of amount by which renewables could reduce the future global emissions of carbon dioxide, sulphur dioxide and nitrogen oxides. It estimated that under the WEC's 'Ecologically Driven' scenario, renewables might lead to significant reductions of between 3650 and 8375 Mt in annual CO 2 emissions depending on the fossil fuel technology they are assumed to displace.

    Fossil fuels provide about 80% of the global energy demand, and this will continue to be the situation for decades to come. In the European Community we are facing two major energy challenges. The first is sustainability, and the second is security of supply, since Europe is becoming more dependent on imported fuels. These challenges are the starting point for the present Risoe Energy Report 6. It gives an overview of the energy scene together with trends and emerging energy technologies. The report presents status and trends for energy technologies seen from a Danish and European perspective from three points of view: security of supply, climate change and industrial perspectives. The report addresses energy supply technologies, efficiency improvements and transport. The report is volume 6 in a series of reports covering energy issues at global, regional and national levels. The individual chapters of the report have been written by staff members from the Technical University of Denmark and Risoe National Laboratory together with leading Danish and international experts. The report is based on the latest research results from Risoe National Laboratory, Technical University of Denmark, together with available internationally recognized scientific material, and is fully referenced and refereed by renowned experts. Information on current developments is taken from the most up-to-date and authoritative sources available.

    1997-01-01

    A prominent feature of renewable energy utilisation is the magnitude of renewable energy that is physically available worldwide. The present paper attempts an economic valuation of development strategies for renewable energy sources (RES) on the basis of the past development of RES markets. It comes to the conclusion that if current energy prices remain largely unchanged, it will be necessary to promote RES technologies differentially according to the technique and type of energy employed or to provide start-up funding. The more probable a long-term increase in energy prices becomes, the greater will be the proportion of successfully promoted technologies. Energy taxes on exhaustible or environmentally harmful energy carriers and other instruments to this end would contribute greatly to the attractivity of RES investment both in terms of national economy and from the viewpoint of the private investor. Renewable energies will play an important role in the hardware and services sectors of the energy market in the decades to come. Long-term promotion of market introduction programmes and unequivocal energy-political aims on the part of the government are needed if the German industry is to have a share in this growing market and be able to offer internationally competitive products [de

    A platform technology has been developed and tested for delivery of intracellular-acting peptides through electrostatically complexed nanoparticles, or nano-polyplexes, formulated from an anionic endosomolytic polymer and cationic therapeutic peptides. This delivery platform has been initially tested and optimized for delivery of two unique vasoactive peptides, a phosphomimetic of heat shock protein 20 and an inhibitor of MAPKAP kinase II, to prevent pathological vasoconstriction (i.e., vasospasm) in human vascular tissue. These peptides inhibit vasoconstriction and promote vasorelaxation by modulating actin dynamics in vascular smooth muscle cells. Formulating these peptides into nano-polyplexes significantly enhances peptide uptake and retention, facilitates cytosolic delivery through a pH-dependent endosomal escape mechanism, and enhances peptide bioactivity in vitro as measured by inhibition of F-actin stress fiber formation. In comparison to treatment with the free peptides, which were endowed with cell-penetrating sequences, the nano-polyplexes significantly increased vasorelaxation, inhibited vasoconstriction, and decreased F-actin formation in the human saphenous vein ex vivo. These results suggest that these formulations have significant potential for treatment of conditions such as cerebral vasospasm following subarachnoid hemorrhage. Furthermore, because many therapeutic peptides include cationic cell-penetrating segments, this simple and modular platform technology may have broad applicability as a cost-effective approach for enhancing the efficacy of cytosolically active peptides.

  19. Technology unlocks tar sands energy

    Energy Technology Data Exchange (ETDEWEB)

    Law, C

    1967-09-25

    Tar sand processing technology has been developed primarily in the categories of extraction techniques and in-situ processing. In October, a $235 million venture into tar sand processing will be inspected by visitors from many points on the globe. A synthetic crude of premium quality will be flowing through a 16-in. pipeline from the Tar Island plant site of Great Canadian Oil Sands to Edmonton. This processing plant uses an extractive mining technique. The tar sand pay zone in this area averages approximately 150 ft in thickness with a 50-ft overburden. It has been estimated that the tar sands cannot be exploited when the formation thickness is less than 100 ft and overburden exceeds the same amount. This indicates that extraction techniques can only be used to recover approximately 15% of the tar sand deposits. An in-situ recovery technique developed by Shell of Canada is discussed in detail. In essence it is selective hydraulic fracturing, followed by the injection of emulsifying chemicals and steam.

    2017-06-07

    Future energy systems will be determined by the increasing relevance of solar and wind energy. Crude oil and gas prices are expected to increase in the long run, and penalties for CO 2 emissions will become a relevant economic factor. Solar- and wind-powered electricity will become significantly cheaper, such that hydrogen produced from electrolysis will be competitively priced against hydrogen manufactured from natural gas. However, to handle the unsteadiness of system input from fluctuating energy sources, energy storage technologies that cover the full scale of power (in megawatts) and energy storage amounts (in megawatt hours) are required. Hydrogen, in particular, is a promising secondary energy vector for storing, transporting, and distributing large and very large amounts of energy at the gigawatt-hour and terawatt-hour scales. However, we also discuss energy storage at the 120-200-kWh scale, for example, for onboard hydrogen storage in fuel cell vehicles using compressed hydrogen storage. This article focuses on the characteristics and development potential of hydrogen storage technologies in light of such a changing energy system and its related challenges. Technological factors that influence the dynamics, flexibility, and operating costs of unsteady operation are therefore highlighted in particular. Moreover, the potential for using renewable hydrogen in the mobility sector, industrial production, and the heat market is discussed, as this potential may determine to a significant extent the future economic value of hydrogen storage technology as it applies to other industries. This evaluation elucidates known and well-established options for hydrogen storage and may guide the development and direction of newer, less developed technologies.

    2006-01-01

    The market penetration rates of 11 different new energy technologies were studied covering energy production and end-use technologies. The penetration rates were determined by fitting observed market data to an epidemical diffusion model. The analyses show that the exponential penetration rates of new energy technologies may vary from 4 up to over 40%/yr. The corresponding take-over times from a 1% to 50% share of the estimated market potential may vary from less than 10 to 70 years. The lower rate is often associated with larger energy impacts. Short take-over times less than 25 years seem to be mainly associated with end-use technologies. Public policies and subsides have an important effect on the penetration. Some technologies penetrate fast without major support explained by technology maturity and competitive prices, e.g. compact fluorescent lamps show a 24.2%/yr growth rate globally. The penetration rates determined exhibit some uncertainty as penetration has not always proceeded close to saturation. The study indicates a decreasing penetration rate with increasing time or market share. If the market history is short, a temporally decreasing functional form for the penetration rate coefficient could be used to anticipate the probable behavior

    The technological development of high-energy lasers is one of the key issues in laser fusion research. This paper reviews several technologies on the Nd:glass laser and KrF excimer laser that are being used in the current laser fusion experiments and related plasma experiments. Based on the GEKKO laser technology, a new high-energy Nd: glass laser system, which can deliver energy from 10 kJ (boad-band operation) to 20 kJ (narrow-band operation), is under construction. The key topics in KrF laser development are improved efficiency and repetitive operation, which aim at the development of a laser driven for fusion reactor. Ultra-intense-laser technology is also very important for fast ignition research. The key technology for obtaining the petawatt output with high beam quality is reviewed. Regarding the uniform laser irradiation required for high-density compression, the beam-smoothing methods on the GEKKO XII laser are reviewed. Finally, we discuss the present status of MJ-class lasers throughout the world, and summarize by presenting the feasibility of various applications of the high-energy lasers to a wide range of scientific and technological fields.

    2011-01-01

    Full Text Available The design of complex circuits as SoCs presents two great challenges to designers. One is the speeding up of system functionality modeling and the second is the implementation of the system in an architecture that meets performance and power consumption requirements. Thus, developing new high-level specification mechanisms for the reduction of the design effort with automatic architecture exploration is a necessity. This paper proposes an Electronic-System-Level (ESL approach for system modeling and cache energy consumption analysis of SoCs called PCacheEnergyAnalyzer. It uses as entry a high-level UML-2.0 profile model of the system and it generates a simulation model of a multicore platform that can be analyzed for cache tuning. PCacheEnergyAnalyzer performs static/dynamic energy consumption analysis of caches on platforms that may have different processors. Architecture exploration is achieved by letting designers choose different processors for platform generation and different mechanisms for cache optimization. PCacheEnergyAnalyzer has been validated with several applications of Mibench, Mediabench, and PowerStone benchmarks, and results show that it provides analysis with reduced simulation effort.

    Ensuring energy security and addressing climate change issues in a cost-effective way are the main challenges of energy policies and in the longer term will be solved only through technology cooperation. To encourage collaborative efforts to meet these energy challenges, the IEA created a legal contract - Implementing Agreement - and a system of standard rules and regulations. This allows interested member and non-member governments or other organisations to pool resources and to foster the research, development and deployment of particular technologies. For more than 30 years, this international technology collaboration has been a fundamental building block in facilitating progress of new or improved energy technologies. There are now 41 Implementing Agreements. This is the third in the series of publications highlighting the recent results and achievements of the IEA Implementing Agreements. This document is arranged in the following sections: Cross-cutting activities (sub-sectioned: Climate technology initiative; Energy Technology Data Eexchange; and Energy technology systems analysis programme); End-use technologies (sub-sectioned: Buildings; Electricity; Industry; and Transport; Fossil fuels (sub-sectioned: Clean Coal Centre; Enhanced oil recovery Fluidized bed conversion; Greenhouse Gas R & D; Multiphase flow sciences); Fusion power; Renewable energies and hydrogen; and For more information (including detail on the IEA energy technology network; IEA Secretariat Implementing Agreement support; and IEA framework. Addresses are given for the Implementing Agreements. The publication is based on core input from the Implementing Agreement Executive Committee.

  7. A Novel Software Platform Extending Advances in Monitoring Technologies to On-demand Decision Support

    Rapid evolution is occurring in the monitoring and assessment of air emissions and their impacts. The development of next generation lower cost sensor technologies creates the potential for much more intensive and far-reaching monitoring networks that provide spatially rich data. While much attention at present is being directed at the types and performance characteristics of sensor technologies, it is important also that the full potential of rich data sources be realized. Parallel to sensor developments, software platforms to display and manage data in real time are increasingly common adjuncts to sensor networks. However, the full value of data can be realized by extending platform capabilities to include complex scientific functions that are integrated into an action-oriented management framework. Depending on the purpose and nature of a monitoring network, there will be a variety of potential uses of the data or its derivatives, for example: statistical analysis for policy development, event analysis, real-time issue management including emergency response and complaints, and predictive management. Moving these functions into an on-demand, optionally mobile, environment greatly increases the value and accessibility of the data. Increased interplay between monitoring data and decision-making in an operational environment is optimised by a system that is designed with equal weight on technical robustness and user experience. A system now being used by several regulatory agencies and a larger number of industries in the US, Latin America, Europe, Australia and Asia has been developed to provide a wide range of on-demand decision-support in addition to the basic data collection, display and management that most platforms offer. With stable multi-year operation, the platform, known as Envirosuite, is assisting organisations to both reduce operating costs and improve environmental performance. Some current examples of its application across a range of applications

    We describe and evaluate the technical, political, and economic challenges involved with widespread adoption of renewable energy technologies. First, we estimate fossil fuel resources and reserves and, together with the current and projected global primary power production rates, estimate the remaining years of oil, gas, and coal. We then compare the conventional price of fossil energy with that from renewable energy technologies (wind, solar thermal, solar electric, biomass, hydroelectric, and geothermal) to evaluate the potential for a transition to renewable energy in the next 20-50 years. Secondly, we evaluate - per the Intergovernmental Panel on Climate Change - the greenhouse constraint on carbon-based power consumption as an unpriced externality to fossil-fuel use, considering global population growth, increased global gross domestic product, and increased energy efficiency per unit GDP. This constraint is projected to drive the demand for carbon-free power well beyond that produced by conventional supply/demand pricing tradeoffs, to levels far greater than current renewable energy demand. Thirdly, we evaluate the level and timescale of R&D investment needed to produce the required quantity of carbon-free power by the 2050 timeframe. Fourth, we evaluate the energy potential of various renewable energy resources to ascertain which resources are adequately available globally to support the projected demand. Fifth, we evaluate the challenges to the chemical sciences to enable the cost-effective production of carbon-free power required. Finally, we discuss the effects of a change in primary power technology on the energy supply infrastructure and discuss the impact of such a change on the modes of energy consumption by the energy consumer and additional demands on the chemical sciences to support such a transition in energy supply.

    The world's concern about the energy supply in the near future, has had as an answer diverse proposals in which two multinational initiatives are highlighted, that of the International Project on Nuclear Innovative Reactors and Fuel Cycles (INPRO) and that of the Generation-l V International Forum (GIF). Both initiatives direct their efforts to the development of new technologies in nuclear energy that would satisfy the energy requirements of the future. In this article, an analysis based on a) the available information on these technologies, b) a joint study (IEA/OECD/IAEA) on the new technologies regarding its capacity to confront the current challenges of the nuclear energy, and c) the authors' experience and knowledge about the phenomenology, design and security of nuclear facilities, is presented. Moreover, the technologies that, in the authors' opinion, will have the better possibilities to compete successfully in the energy markets and could be one of the viable options to satisfy the energy demands of the future, are described.

    Full Text Available Nowadays, with the rapid development of modern information technology, the college students could not preferably choose and learn to enhance their own art appreciation capability. Therefore, the colleges and universities have a more urgent desire to organize, develop and provide a good platform to enhance the college students’ art appreciation capability based on modern information technology. This paper describes how to enhance the art appreciation capability in detail, and designs and analyzes the platform to enhance college students’ art appreciation capability based on modern information technology---the “Music Corner” and the “Dance Corner”, indicating that the exchange platform built with modern information technology can promotes the college students’ art appreciation capability. Finally, through the analysis of statistical results of the questionnaire, college students are fonder of art appreciation after the establishment of platform, more inclined to the comprehensive learning of art, more brave to express their own sense of art, and fonder of artistic creation.

    The development, operation, and analysis of data from cubesats can promote science education and spur technology utilization in emerging and developing nations. This platform offers uniquely low construction and launch costs together with a comparative ubiquity of launch providers; factors that have led more than 80 universities and several emerging nations to develop programs in this field. Their small size and weight enables cubesats to “piggyback” on rocket launches and accompany orbiters travelling to Moon and Mars. It is envisaged that constellations of cubesats will be used for larger science missions. We present a brief history, technology overview, and summary of applications in science and industry for these small satellites. Cubesat technical success stories are offered along with a summary of pitfalls and challenges encountered in both developed and emerging nations. A discussion of economic and public policy issues aims to facilitate the decision-making process for those considering utilization of this unique technology.

    The most available and affordable sources of energy in today's economic structure are fossil fuels, namely, oil, gas, and coal. Fossil fuels are non-renewable, have limited reserves, and have serious environmental problems associated with their use. Coal and nuclear energy are used in central and bulky power stations to produce electricity, and then this electricity is delivered to customers via expensive transmission lines and distribution systems. Delivering electric power via transmission and distribution lines to the electricity users is associated with high electric power losses. These power losses are costly burdens on power suppliers and users. One of the advantages of decentralized generation (DG) is that DG is capable of minimizing power losses because electric power is generated at the demand site. The world is facing two major energy-related issues, short term and long term. These issues are (i) not having enough and secure supplies of energy at affordable prices and (ii) environmental damages caused by consuming too much energy in an unsustainable way. A significant amount of the current world energy comes from limited resources, which when used, cannot be replaced. Hence the energy production and consumption do not seem to be sustainable, and also carries the threat of severe and irreversible damages to the environment including climate change.The price of energy is increasing and there are no evidences suggesting that this trend will reverse. To compensate for this price increase we need to develop and use high energy efficient technologies and focusing on energy technologies using renewable sources with less energy conversion chains, such as solar and wind. The world has the potential to expand its capacity of clean, renewable, and sustainable energy to offset a significant amount of greenhouse gas emissions from conventional power use. The increasing utilization of alternative sources such as hydro, biomass, geothermal, ocean energy, solar and

    Norsk Hydro Technology Ventures, a venture capital fund recently set up by Norsk Hydro, will raise equity capital to companies that are developing promising new projects on new energy technology or to investment funds promoting such projects. Norsk Hydro will withdraw from the investments when the projects have reached commercialization or are listed on the stock exchange. There is a well-developed market for venture capital in the energy sector and a strong international competition for investments in good projects. The sharp environmental focus on fossil fuels and climate gases has boosted the research on new energy technologies. Another and more important factor is the fact that modern society with its heavy dependence on the computer is vulnerable to power failure

    Both anecdotal evidence and the innovation literature indicate that important advances in energy technology have made use of knowledge originating in other technological areas. This study uses the set of U.S. patents granted from 1976 to 2006 to assess the role of knowledge acquired from outside each energy patent's technological classification. It identifies the effect of external knowledge on the forward citation frequency of energy patents. The results support the claim above. Regression coefficients on citations to external prior art are positive and significant. Further, the effect of external citations is significantly larger than that of other types of citations. Conversely, citations to prior art that is technologically near have a negative effect on forward citation frequency. These results are robust across several alternative specifications and definitions of whether each flow of knowledge is external. Important energy patents have drawn heavily from external prior art categorized as chemical, electronics, and electrical; they cite very little prior art from computers, communications, and medical inventions.

    Globally, the Kingdom of Saudi Arabia (KSA) desalinates the largest capacity of seawater but through energy-intensive thermal processes such as multi-stage flash (MSF) distillation (>10 kW h per m3 of desalinated water, including electrical and thermal energies). In other regions where fossil energy is more expensive and not subsidized, seawater reverse osmosis (SWRO) is the most common desalination technology but it is still energy-intensive (3-4 kW h_e/m3). Both processes therefore lead to the emission of significant amounts of greenhouse gases (GHGs). Moreover, MSF and SWRO technologies are most often used for large desalination facilities serving urban centers with centralized water distribution systems and power grids. While renewable energy (RE) sources could be used to serve centralized systems in urban centers and thus provide an opportunity to make desalination greener, they are mostly used to serve rural communities off of the grid. In the KSA, solar and geothermal energy are of most relevance in terms of local conditions. Our group is focusing on developing new desalination processes, adsorption desalination (AD) and membrane distillation (MD), which can be driven by waste heat, geothermal or solar energy. A demonstration solar-powered AD facility has been constructed and a life cycle assessment showed that a specific energy consumption of <1.5 kW h_e/m3 is possible. An innovative hybrid approach has also been explored which would combine solar and geothermal energy using an alternating 12-h cycle to reduce the probability of depleting the heat source within the geothermal reservoir and provide the most effective use of RE without the need for energy storage. This paper highlights the use of RE for desalination in KSA with a focus on our group\\'s contribution in developing innovative low energy-driven desalination technologies. © 2014 Elsevier Ltd.

    The programme is divided into system and technology parts. The aim of system studies is to determine, on the basis of lifecycle analyses, long-term environmental-technological aims for various fields (energy, industry) and to find out an optimum strategy for reaching these aims. The analysis will give data on emission reduction costs and on fields, where technical improvements are required, and will determine the limits set by environmental factors for future technical development. Environmental impacts will be discussed from national and economic viewpoints. Technological development is dependent on new ideas. The aim is to indicate possibilities for reducing emissions from energy use of peat and wood, for low-emission production at least on one industrial field (wood-processing industry), to establish emission measuring and control methods, to indicate utilization alternatives for solid matter separated at power plants, and to find out operable alternatives for the energy use of wastes. Other ventures of significance will also be financed: survey of 'new' emissions and development of their measuring and purification methods. The field of the programme will be divided into synergic sub-fields: systematics of emission chains, fields of operation (energy and environment problems in the wood-processing industries), development of flue gas purification technology, measuring and control technology, by-products of power plants, emissions from peat production, etc

    Technological choices largely determine the long-term characteristics of industrial society, including impacts on the natural environment. However, the treatment of technology in existing models that are used to project economic and environmental futures remains highly stylized. Based on work over two decades at IIASA, we present a useful typology for technology analysis and discuss methods that can be used to analyze the impact of technological changes on the global environment, especially global warming. Our focus is energy technologies, the main source of many atmospheric environmental problems. We show that much improved treatment of technology is possible with a combination of historical analysis and new modeling techniques. In the historical record, we identify characteristic 'learning rates' that allow simple quantified characterization of the improvement in cost and performance due to cumulative experience and investments. We also identify patterns, processes and timescales that typify the diffusion of new technologies in competitive markets. Technologies that are long-lived and are components of interlocking networks typically require the longest time to diffuse and co-evolve with other technologies in the network; such network effects yield high barriers to entry even for superior competitors. These simple observations allow three improvements to modeling of technological change and its consequences for global environmental change. One is that the replacement of long-lived infrastructures over time has also replaced the fuels that power the economy to yield progressively more energy per unit of carbon pollution - from coal to oil to gas. Such replacement has 'decarbonized' the global primary energy supply 0.3% per year. In contrast, most baseline projections for emissions of carbon, the chief cause of global warming, ignore this robust historical trend and show Iittle or no decarbonization. A second improvement is that by incorporating learning curves and

    This paper analyses the potential for the involvement of different types of stakeholders in the Implementing Geological Disposal Technology Platform (IGD-TP). This analysis was conducted as part of the InSOTEC project, a three-year (2011- 2014) collaborative research project funded under the 7. Euratom Framework Programme (Grant Agreement nr. 269906). In our analysis, we consider the extent to which the IGDTP's practice as regards to stakeholder involvement matches its discourse, and what potential for improvement exists given its structural organisation as a European Technology Platform (ETPs). Technology Platforms (TPs) can be understood as knowledge networks, deliberately set up to influence (research) policy in a specific domain. We therefore use knowledge networks as a conceptual approach and look at the IGD-TP as a complex network which includes actors, knowledge and practices across different countries, focusing on a very specific topic (i.e. implementing geological disposal). We compare the way different stakeholders are involved in the IGD-TP to the practice of other ETPs, and explore how the IGD-TP is viewed by its members and by outsiders to the platform Applying Callon's framework of knowledge co-production (1999) we come to define different degrees of interaction between science, society and policy in view of defining research and development (R and D) priorities [1]. Subsequently we describe how these interactions could be conceptualised and interpreted for the IGD-TP. The current approach of the IGDTP can be mainly understood as classical model involving mainly expert stakeholders and scientists. Where there seems to be a good representation among IGD-TP members of industry, research institutes, and some members of the academic community this is not the case for other types of stakeholders, such as public authorities or civil society. At this stage, the overall approach of the IGD-TP would seem to restrict the scope of stakeholder

    2004-10-11

    The energy use in America's commercial and residential building sectors is large and growing. Over 38 quadrillion Btus (Quads) of primary energy were consumed in 2002, representing 39% of total U.S. energy consumption. While the energy use in buildings is expected to grow to 52 Quads by 2025, a large number of energy-related technologies exist that could curtail this increase. In recent years, improvements in such items as high efficiency refrigerators, compact fluorescent lights, high-SEER air conditioners, and improved building shells have all contributed to reducing energy use. Hundreds of other technology improvements have and will continue to improve the energy use in buildings. While many technologies are well understood and are gradually penetrating the market, more advanced technologies will be introduced in the future. The pace and extent of these advances can be improved through state and federal R&D. This report focuses on the long-term potential for energy-efficiency improvement in buildings. Five promising technologies have been selected for description to give an idea of the wide range of possibilities. They address the major areas of energy use in buildings: space conditioning (33% of building use), water heating (9%), and lighting (16%). Besides describing energy-using technologies (solid-state lighting and geothermal heat pumps), the report also discusses energy-saving building shell improvements (smart roofs) and the integration of multiple energy service technologies (CHP packaged systems and triple function heat pumps) to create synergistic savings. Finally, information technologies that can improve the efficiency of building operations are discussed. The report demonstrates that the United States is not running out of technologies to improve energy efficiency and economic and environmental performance, and will not run out in the future. The five technology areas alone can potentially result in total primary energy savings of between 2 and

  2. Understanding China's renewable energy technology exports

    Liu, Jialu; Goldstein, Don

    2013-01-01

    China became a major player in renewable energy (RE) technology during the 2000s. Chinese solar PV cell and module makers quickly dominated global sales in that industry, while the country's wind turbine producers became poised for significant exports after capturing their rapidly growing home market. In countries like the US, Chinese RE technology strength has been met with claims of excessive governmental support of exports. This study examines to what extent Chinese firms' solar PV and wind technology successes have been enabled by policy supports, and whether those policies appear to have been driven by broader goals versus RE export promotion per se. The evidence suggests that governmental policy toward both wind and solar originated in a push for export-competitive Chinese companies. But the specifics differed substantially due to the particular requirements of building technological capabilities in each: export readiness necessitated substantial support for domestic installation of wind but not solar PV power. The findings also suggest that as the decade of the 2000s progressed, environmental goals played an increasing role alongside export promotion in motivating and shaping Chinese RE technology policies. - Highlights: ► Export policy in the rise of Chinese renewable energy technologies is studied. ► Policy supported wind turbine firms' capabilities via domestic uptake, not exports. ► Pre-2009 solar module exports enjoyed, but did not depend on, export subsidies. ► Renewables development also fit wider technology and environmental policy goals.

    Melioidosis is a serious emerging endemic infectious disease caused by Burkholderia pseudomallei, a gram-negative pathogen. Septicemic melioidosis has a mortality rate of 50% even with treatment. Like other gram-negative bacteria, B. pseudomallei is resistant to a number of antibiotics and multi-drug resistant B. pseudomallei is beginning to be encountered in hospitals. There is a clear medical need to develop new treatment options to manage this disease. We used Burkholderia thailandensis (a BSL-2 class organism) to infect Caenorhabditis elegans and set up a surrogate whole animal infection model of melioidosis that we could run in a 384 microtitre plate and establish a whole animal HTS assay. We have optimized and validated this assay in a fluorescence-based format that can be run on our automated screening platforms. This assay has now been used to screen over 300,000 compounds from our small molecule library and we are in the process of characterizing the hits obtained and select compounds for further studies. We have thus established a biologically relevant assay technology platform to screen for antibacterial compounds and used this platform to identify new compounds that may find application in treating melioidosis infections.

    Smart solutions to reduce the energy consumption are continuously part of investigation in the refrigeration technology. This article subscribed the technology on which way energy can be saved at the operation of screw compressors which are used in air conditioners and refrigerating machinery. The combination of frequency control and Vi-control (intrinsic volumetric ratio) such as researched in the laboratory of RefComp is for the user attractive because the energy efficiency during part load operation is much better. Smart uses of thermodynamics, electric technology and electronic control are the basics of these applications. According to the manufacturer's information it is possible with these new generation screw compressors to save approx. 26% energy in comparison with the standard screw compressor. [Dutch] In dit artikel wordt de technologie omschreven waarmee veel energie bespaard kan worden bij schroefcompressoren die worden gebruikt in airconditioningsystemen en koel- en vriesinstallaties. De combinatie van frequentieregeling en Vi- regeling (Vi is de intrinsieke volumetrische verhouding) zoals onderzocht in het laboratorium van RefComp biedt de gebruiker veel voordelen doordat de energie-efficintie van de compressor tijdens deellast enorm wordt verbeterd. Slim gebruik van thermodynamika, elektrotechniek en elektronica vormen de basis van deze toepassing. Volgens de fabrikant kan met deze nieuwe generatie schroefcompressoren circa 26 procent op het energiegebruik tijdens deellast worden bespaard in vergelijking met de standaard serie schroefcompressoren.

    The international community agrees that the new technology based on the use of Unmanned Air Vehicles High Altitude Very long Endurance (UAV-HAVE) could play an important role for the development of remote sensing and telecommunication applications. A UAV-HAVE vehicle can be described as a low- cost flying infrastructure (compared with satellites) optimized for long endurance operations at an altitude of about 20 km. Due to such features, its role is similar to satellites, with the major advantages of being less expensive, more flexible, movable on demand, and suitable for a larger class of applications. According to this background, Politecnico di Torino is involved as coordinator in an important project named HeliNet, that represent one of the main activities in Europe in the field of stratospheric platforms, and is concerned with the development of a network of UAV-HAVE aircraft. A key point of this project is the feasibility study for the provision of several services, namely traffic monitoring, environmental surveillance, broadband communications and navigation. This paper reports preliminary results on the HeliNet imaging system and its remote sensing applications. In fact, many environmental surveillance services (e.g. regional public services for agriculture, hydrology, fire protection, and more) require very high-resolution imaging, and can be offered at a lower cost if operated by a shared platform. The philosophy behind the HeliNet project seems to be particularly suitable to manage such missions. In particular, we present a system- level study of possible imaging payloads to be mounted on- board of a stratospheric platform to collect Earth observation data. Firstly, we address optical payloads such as multispectral and/or hyperspectral ones, which are a very short-term objective of the project. Secondly, as an example of mid-term on-board payload, we examine the possibility to carry on the platform a light-SAR system. For both types of payload, we show

  8. Essays on Energy Technology Innovation Policy

    Science.gov (United States)

    Chan, Gabriel Angelo Sherak

    Motivated by global climate change, enhancing innovation systems for energy technologies is seen as one of the largest public policy challenges of the near future. The role of policy in enhancing energy innovation systems takes several forms: public provision of research and develop funding, facilitating the private sector's capability to develop new technologies, and creating incentives for private actors to adopt innovative and appropriate technologies. This dissertation explores research questions that span this range of policies to develop insights in how energy technology innovation policy can be reformed in the face of climate change. The first chapter of this dissertation explores how decision making to allocate public research and development funding could be improved through the integration of expert technology forecasts. I present a framework to evaluate and optimize the U.S. Department of Energy's research and development portfolio of applied energy projects, accounting for spillovers from technical complimentary and competition for the same market share. This project integrates one of the largest and most comprehensive sets of expert elicitations on energy technologies (Anadon et al., 2014b) in a benefit evaluation framework. This work entailed developing a new method for probability distribution sampling that accommodates the information that can be provided by expert elicitations. The results of this project show that public research and development in energy storage and solar photovoltaic technologies has the greatest marginal returns to economic surplus, but the methodology developed in this chapter is broadly applicable to other public and private R&D-sponsoring organizations. The second chapter of this dissertation explores how policies to transfer technologies from federally funded research laboratories to commercialization partners, largely private firms, create knowledge spillovers that lead to further innovation. In this chapter, I study the U

    2016-01-01

    The development of civilisation is linked inextricably with growing demand for electricity. Thus, the still-rapid increase in the level of utilisation of natural resources, including fossil fuels, leaves it more and more urgent that conventional energy technologies and the potential of the renewable energy sources be made subject to re-evaluation. It is estimated that last 200 years have seen use made of more than 50% of the available natural resources. Equally, if economic forecasts prove accurate, for at least several more decades, oil, natural gas and coal will go on being the basic primary energy sources. The alternative solution represented by nuclear energy remains a cause of considerable public concern, while the potential for use to be made of renewable energy sources is seen to be very much dependent on local environmental conditions. For this reason, it is necessary to emphasise the impact of research that focuses on the further sharpening-up of energy efficiency, as well as actions aimed at increasing society's awareness of the relevant issues. The history of recent centuries has shown that rapid economic and social transformation followed on from the industrial and technological revolutions, which is to say revolutions made possible by the development of power-supply technologies. While the 19th century was "the age of steam" or of coal, and the 20th century the era of oil and gas, the question now concerns the name that will at some point come to be associated with the 21st century. In this paper, the subjects of discussion are primary energy consumption and energy resources, though three international projects on the global scale are also presented, i.e. ITER, Hydrates and DESERTEC. These projects demonstrate new scientific and technical possibilities, though it is unlikely that commercialisation would prove feasible before 2050. Research should thus be focused on raising energy efficiency. The development of high-efficiency technologies that

    Full Text Available Wind-wave hybrid power generation systems have the potential to become a significant source of affordable renewable energy. However, their strong interactions with both wind- and wave-induced forces raise a number of technical challenges for modelling. The present study undertakes a numerical investigation on multi-body hydrodynamic interaction between a wind-wave hybrid floating platform and multiple wave energy converters (WECs in a frequency domain. In addition to the exact responses of the platform and the WECs, the power take-off (PTO mechanism was taken into account for analysis. The coupled hydrodynamic coefficients and wave exciting forces were obtained from WAMIT, the 3D diffraction/radiation solver based on the boundary element method. The overall performance of the multiple WECs is presented and compared with the performance of a single isolated WEC. The analysis showed significant differences in the dynamic responses of the WECs when the multi-body interaction was considered. In addition, the PTO damping effect made a considerable difference to the responses of the WECs. However, the platform response was only minimally affected by PTO damping. With regard to energy capture, the interaction effect of the designed multiple WEC array layout is evaluated. The WEC array configuration showed both constructive and destructive effects in accordance with the incident wave frequency and direction.

    Minilaparoscopy is an attractive approach for hysterectomy due to advantages such as reduced morbidities and enhanced cosmesis. However, it has not been popularized due to the lack of suitable instruments and high technical demand. We aim to highlight the first case of minilaparoscopic hysterectomy reported in Asia and the use of a new integrated energy platform, Thunderbeat. We would like to propose an alternative method of instrumentation, so as to improve the feasibility and safety of minilaparoscopic hysterectomy. The first minilaparoscopic hysterectomy in Singapore was successfully completed using the alternative instrumentation and new energy platform. There was no conversion or complication during the surgery. The patient recovered uneventfully. To our knowledge, this is the first report on the use of such alternative instrumentation. This approach in instrumentation and the new energy platform will improve the feasibility and speed of the surgery and ensure safety in our patients. © 2014 The Authors.

    The free energy calculation library PLUMED has been incorporated into the OpenMM simulation toolkit, with the purpose to perform enhanced sampling MD simulations using the AMOEBA polarizable force field on GPU platform. Two examples, (I) the free energy profile of water pair separation (II) alanine dipeptide dihedral angle free energy surface in explicit solvent, are provided here to demonstrate the accuracy and efficiency of our implementation. The converged free energy profiles could be obtained within an affordable MD simulation time when the AMOEBA polarizable force field is employed. Moreover, the free energy surfaces estimated using the AMOEBA polarizable force field are in agreement with those calculated from experimental data and ab initio methods. Hence, the implementation in this work is reliable and would be utilized to study more complicated biological phenomena in both an accurate and efficient way. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

    Full Text Available Over the last decade, the growing need in disease diagnostics has stimulated rapid development of new technologies with unprecedented capabilities. Recent emerging infectious diseases and epidemics have revealed the shortcomings of existing diagnostics tools, and the necessity for further improvements. Optical biosensors can lay the foundations for future generation diagnostics by providing means to detect biomarkers in a highly sensitive, specific, quantitative and multiplexed fashion. Here, we review an optical sensing technology, Interferometric Reflectance Imaging Sensor (IRIS, and the relevant features of this multifunctional platform for quantitative, label-free and dynamic detection. We discuss two distinct modalities for IRIS: (i low-magnification (ensemble biomolecular mass measurements and (ii high-magnification (digital detection of individual nanoparticles along with their applications, including label-free detection of multiplexed protein chips, measurement of single nucleotide polymorphism, quantification of transcription factor DNA binding, and high sensitivity digital sensing and characterization of nanoparticles and viruses.

    Environmental data for wind energy conversion systems (WECSs) have been generated in support of the Technology Assessment of Solar Energy (TASE) program. Two candidates have been chosen to characterize the WECS that might be deployed if this technology makes a significant contribution to the national energy requirements. One WECS is a large machine of 1.5-MW-rated capacity that can be used by utilities. The other WECS is a small machine that is characteristic of units that might be used to meet residential or small business energy requirements. Energy storage systems are discussed for each machine to address the intermittent nature of wind power. Many types of WECSs are being studied and a brief review of the technology is included to give background for choosing horizontal axis designs for this study. Cost estimates have been made for both large and small systems as required for input to the Strategic Environmental Assessment Simulation (SEAS) computer program. Material requirements, based on current generation WECSs, are discussed and a general discussion of environmental impacts associated with WECS deployment is presented.

    The European renewable energy industry has the potential to be a world leader. This has been achieved within the European region for specific technologies, through a set of policy activities at a national and regional level, driven primarily by employment, energy self-sufficiency and industrial competitiveness. Using the experience gained in recent years, European industry has the opportunity to continue to expand its horizons on a worldwide level. Through the use of the SAFIRE rational energy model, an assessment has been made of the future penetration of renewable energy within Europe and the effects on these socio-economic factors. In conjunction with these outputs, assessments of the worldwide markets for wind, photovoltaics, solar thermal plant and biomass have been assessed. A case study of the Danish wind industry is used as a prime example of a success story from which the learning opportunities are replicated to other industries, so that the European renewable energy industry can achieve its potential.

    2014-01-01

    We describe the main features and preliminary evaluation of Positive Technology, a free mobile platform for the self-management of psychological stress (http://positiveapp.info/). The mobile platform features three main components: (i) guided relaxation, which provides the user with the opportunity of browsing a gallery of relaxation music and video-narrative resources for reducing stress; (ii) 3D biofeedback, which helps the user learning to control his/her responses, by visualizing variations of heart rate in an engaging 3D environment; (iii) stress tracking, by the recording of heart rate and self-reports. We evaluated the Positive Technology app in an online trial involving 32 participants, out of which 7 used the application in combination with the wrist sensor. Overall, feedback from users was satisfactory and the analysis of data collected online indicated the capability of the app for reducing perceived stress levels. A future goal is to improve the usability of the application and include more advanced stress monitoring features, based on the analysis of heart rate variability indexes.

    2005-01-01

    Solar energy systems (photovoltaics, solar thermal, solar power) provide significant environmental benefits in comparison to the conventional energy sources, thus contributing, to the sustainable development of human activities. Sometimes however, their wide scale deployment has to face potential negative environmental implications. These potential problems seem to be a strong barrier for a further dissemination of these systems in some consumers. To cope with these problems this paper presents an overview of an Environmental Impact Assessment. We assess the potential environmental intrusions in order to ameliorate them with new technological innovations and good practices in the future power systems. The analysis provides the potential burdens to the environment, which include - during the construction, the installation and the demolition phases, as well as especially in the case of the central solar technologies - noise and visual intrusion, greenhouse gas emissions, water and soil pollution, energy consumption, labour accidents, impact on archaeological sites or on sensitive ecosystems, negative and positive socio-economic effects

    1994-09-01

    The U.S. Department of Energy (DOE) Office of Industrial Technology`s (OIT`s) Technology Benefits Recording System (TBRS) was developed by Pacific Northwest Laboratory (PNL). The TBRS is used to organize and maintain records of the benefits accrued from the use of technologies developed with the assistance of OIT. OIT has had a sustained emphasis on technology deployment. While individual program managers have specific technology deployment goals for each of their ongoing programs, the Office has also established a separate Technology Deployment Division whose mission is to assist program managers and research and development partners commercialize technologies. As part of this effort, the Technology Deployment Division developed an energy-tracking task which has been performed by PNL since 1977. The goal of the energy-tracking task is to accurately assess the energy savings impact of OIT-developed technologies. In previous years, information on OIT-sponsored technologies existed in a variety of forms--first as a hardcopy, then electronically in several spreadsheet formats that existed in multiple software programs. The TBRS was created in 1993 for OIT and was based on information collected in all previous years from numerous industrial contacts, vendors, and plants that have installed OIT-sponsored technologies. The TBRS contains information on technologies commercialized between 1977 and the present, as well as information on emerging technologies in the late development/early commercialization stage of the technology life cycle. For each technology, details on the number of units sold and the energy saved are available on a year-by-year basis. Information regarding environmental benefits, productivity and competitiveness benefits, or impact that the technology may have had on employment is also available.

    1996-01-01

    A new technology has been implemented using an open-quotes active-detectorclose quotes comprised of two computed radiography (CR) imaging plates in a sandwich geometry for dual-energy radiography. This detector allows excellent energy separation, short exposure time, and high signal to noise ratio (SNR) for clinically robust open-quotes bone-onlyclose quotes and open-quotes soft-tissue onlyclose quotes images with minimum patient motion. Energy separation is achieved by two separate exposures at widely different kVp's: the high energy (120 kVp + 1.5 mm Cu filter) exposure is initiated first, followed by a short burst of intense light to erase the latent image on the front plate, and then a 50 kVp (low energy) exposure. A personal computer interfaced to the x-ray generator, filter wheel, and active detector system orchestrates the acquisition sequence within a time period of 150 msec. The front and back plates are processed using a CR readout algorithm with fixed speed and wide dynamic range. open-quotes Bone-onlyclose quotes and open-quotes soft-tissue onlyclose quotes images are calculated by geometric alignment of the two images and application of dual energy decomposition algorithms on a pixel by pixel basis. Resultant images of a calibration phantom demonstrate an increase of SNR 2 / dose by ∼73 times when compared to a single exposure open-quotes passive-detectorclose quotes comprised of CR imaging plates, and an ∼8 fold increase compared to a screen-film dual-energy cassette comprised of different phosphor compounds. In conclusion, dual energy imaging with open-quotes active detectorclose quotes technology is clinically feasible and can provide substantial improvements over conventional methods for dual-energy radiography

    2014-11-21

    Alternative energy technologies are greatly hindered by significant limitations in materials science. From low activity to poor stability, and from mineral scarcity to high cost, the current materials are not able to cope with the significant challenges of clean energy technologies. However, recent advances in the preparation of nanomaterials, porous solids, and nanostructured solids are providing hope in the race for a better, cleaner energy production. The present contribution critically reviews the development and role of mesoporosity in a wide range of technologies, as this provides for critical improvements in accessibility, the dispersion of the active phase and a higher surface area. Relevant examples of the development of mesoporosity by a wide range of techniques are provided, including the preparation of hierarchical structures with pore systems in different scale ranges. Mesoporosity plays a significant role in catalysis, especially in the most challenging processes where bulky molecules, like those obtained from biomass or highly unreactive species, such as CO2 should be transformed into most valuable products. Furthermore, mesoporous materials also play a significant role as electrodes in fuel and solar cells and in thermoelectric devices, technologies which are benefiting from improved accessibility and a better dispersion of materials with controlled porosity.

    2011-01-01

    Interactions of energy policies with water technology development in China are investigated using a hybrid input-output model and scenario analysis. The implementation of energy policies and water technology development can produce co-benefits for each other. Water saving potential of energy technology development is much larger than that of new energy exploitation. From the viewpoint of proportions of water saving co-benefits of energy policies, energy sectors benefit the most. From the viewpoint of proportions of energy saving and CO 2 mitigation co-benefits of water technology development, water sector benefits the most. Moreover, economic sectors are classified into four categories concerning co-benefits on water saving, energy saving and CO 2 mitigation. Sectors in categories 1 and 2 have big direct co-benefits. Thus, they can take additional responsibility for water and energy saving and CO 2 mitigation. If China implements life cycle materials management, sectors in category 3 can also take additional responsibility for water and energy saving and CO 2 mitigation. Sectors in category 4 have few co-benefits from both direct and accumulative perspectives. Thus, putting additional responsibility on sectors in category 4 might produce pressure for their economic development. -- Highlights: ► Energy policies and water technology development can produce co-benefits for each other. ► For proportions of water saving co-benefits of energy policies, energy sectors benefit the most. ► For proportions of energy saving and CO 2 mitigation co-benefits of water policy, water sector benefits the most. ► China’s economic sectors are classified into four categories for policy implementation at sector scale.

    2010-07-01

    The Nordic Energy Technology Scoreboard provides a tool for understanding the state of low-carbon energy technology development in the Nordic region. It assesses the five Nordic countries of Denmark, Finland, Iceland, Norway and Sweden, alongside reference countries and regions including: The United Kingdom, Germany, Spain, Portugal, France, Italy, the Netherlands, Austria, USA, Japan and the EU 27. It focuses on five low-carbon energy technologies: Wind, photovoltaic (PV) solar, bio-fuels, geothermal, and carbon capture and storage (CCS). This scoreboard was developed as a pilot project with a limited scope of technologies, countries and indicators. In addition to providing a tool for decision-makers, it aimed to act as a catalyst for the future development of scoreboards and a vehicle to promote better data collection. Low-carbon energy technologies are not easy to measure. This is due to a variety of factors that much be kept in account when developing scoreboards for this purpose. Many low-carbon technologies are still at immature stages of development. Sound comparable data requires common definitions and standards to be adopted before collection can even take place. This process often lags behind the development of low-carbon technologies, and there are therefore considerable data availability and categorisation issues. The diversity of technologies and their different stages of development hamper comparability. The IEA classifies low-carbon technologies into three categories. The most mature includes hydropower, onshore wind, biomass CHP, and geothermal energy, the second most mature includes PV solar and offshore wind power, while the least mature includes concentrating solar power, CCS and ocean energy. This is problematic as less mature technologies are underrepresented in later stages of the innovation system. Many low-carbon technologies are systemic, meaning progress in developing one technology may hinge on developments in a connected technology

    The transition to a low carbon economy will take decades and affect the entire economy. There is a timely opportunity for investment in energy infrastructure. However, decisions to invest in technologies that are fully aligned with policy and society priorities do not necessarily come naturally, although it will profoundly affect the level of sustainability of the European energy system for decades to come. Technology development needs to be accelerated and prioritized at the highest level of the European policy agenda. This is the essence of the European Strategic Energy Technology Plan (SET-Plan). The SET-Plan makes concrete proposals for action to establish an energy technology policy for Europe, with a new mind-set for planning and working together and to foster science for transforming energy technologies to achieve EU energy and climate change goals for 2020, and to contribute to the worldwide transition to a low carbon economy by 2050. This paper gives an overview of the SET-Plan initiative and highlights its latest developments. It emphasises the importance of information in support of decision-making for investing in the development of low carbon technologies and shows the first results of the technology mapping undertaken by the newly established Information System of the SET-Plan (SETIS).(author)

Of Kansas; Max Planck Institute for dynamics of Complex Technical Systems; Fraunhofer USA Center for Molecular Biotechnology; US Dep. of Agriculture Animal and Plant Health Inspection Service, etc. In historic literature there are data about inoculation practices in antique China, Persia, India, Byzantium, native Americans, some African population. In modern immunology since the end of XIX century the vaccines were produced at the in vivo platforms - in animals (rabbits, mice, cows). Since 1931 due to E. Goodpasture' elaboration most virus vaccines were and are produced at the in ovo platform. In 1949 J.F. Enders elaborated large-scale polio virus production in the primary culture of monkey kidney cells in vitro. Up to day primary culture of chiken embrio fibroblasts are used to large-scale production of vaccine viruses of measles, mumps, rabies. Since 2000-th in Western countries most part of virus vaccines were began to produced via a cultivation in continuous tumor cell lines. The last technology is the most low cost for large-scale production of vaccines. We review several new biotechnological platforms for the production of the recombinant protein or virus-like particles as subunit vaccines: plant system, algae, mushrooms, insect cells, etc. Beside of good purpose of vaccination - prophylactic of several infectious

    2017-08-08

    In this paper, we present a tiny networked mobile platform, termed Tiny-Web-Thing ( T-Wing ), which allows the sharing of data-intensive content among objects in cyber physical systems. The object includes mobile platforms like a smartphone, and Internet of Things (IoT) platforms for Human-to-Human (H2H), Human-to-Machine (H2M), Machine-to-Human (M2H), and Machine-to-Machine (M2M) communications. T-Wing makes it possible to host rich web content directly on their objects, which nearby objects can access instantaneously. Using a new mechanism that allows the Wi-Fi interface of the object to be turned on purely on-demand, T-Wing achieves very high energy efficiency. We have implemented T-Wing on an embedded board, and present evaluation results from our testbed. From the evaluation result of T-Wing , we compare our system against alternative approaches to implement this functionality using only the cellular or Wi-Fi (but not both), and show that in typical usage, T-Wing consumes less than 15× the energy and is faster by an order of magnitude.

  17. Institutional options for rural energy access: Exploring the concept of the multifunctional platform in West Africa

    International Nuclear Information System (INIS)

    Nygaard, Ivan

    2010-01-01

    The concept of the multifunctional platform for rural energy access has increasingly been supported by donors in five West African countries since 1994. While it is often referred to as a highly successful concept, recent reviews and interviews with local stakeholders in Mali and Burkina Faso indicate that the high aspirations to be found in project descriptions and early evaluations are only partly reflected in activities on the ground. This paper illustrates how the multipurpose aspects of the platform have made the concept a nexus of potential achievements that are highly valued in the dominant discourse of development, and how including concerns, such as poverty alleviation, gender equity, local democracy, decentralisation and the environment, have attracted donors outside the energy sector. The paper thus argues that, while the integration of multiple technical functions, preconceived organisational set-ups and local fuel production have in fact had limited or even adverse effects on the outcome of the multifunctional platform programme, these virtues have proved essential in presenting the concept at the policy level. This analysis of the dilemma between mobilizing funding and implementing practical programmes provides an argument for building development aid on existing structures instead of inventing new complicated concepts and approaches.

  19. Energy - Resources, technologies and power issues

    International Nuclear Information System (INIS)

    Mazzucchi, Nicolas

    2017-01-01

    For a better understanding of complex relationships between States, enterprises and international bodies, the author proposes a detailed analysis of power issues which structure the energy sector at the world level. He first considers the energy policy of a country as a result of an arbitration between three main concerns (access to energy, energy security, and struggle against climate change) which are differently addressed depending on consumption and production profiles of the country, and on its geographic and political characteristics. The author then proposes a synthetic overview of this landscape by analysing the history of exploitation of different energy sources (oil, coal, gas, uranium) and by proposing a regional analysis of resources. In the next part, he addresses various aspects of energy transports (bottlenecks of sea transport, trans-national grids, geopolitical restructuring of pipelines in front of the development of new LNG terminals). Then, for different regions, he describes the various modes of energy consumption, and challenges related to the transformation of this consumption due to the emergence of renewable energies. He analyses and discusses international mechanisms which underlie energy markets, and power issues which govern them. He shows that nuclear and renewable energies in fact strengthen the dependence on strategic materials and on technological companies. A chapter proposes an analysis of relationships between three prevailing actors in the elaboration of energy policies (enterprises, State and civil society) with their reciprocal influences, moments of collaboration, and information exchange or withholding. The last chapter addresses the study of power rivalries in the elaboration of policies for the struggle against climate change, and proposes a critical review of international organisations which square them

    The aim of this study is to discuss how information about the development and use of bio-energy is forwarded and disseminated to general public via the Internet in China. Furthermore, this study also explores in what manner the information of renewable energy policies is presented. A research method used in this study is an application of content analysis. Altogether 19 energy-related web platforms were found by searching keywords, such as 'energy net' or 'renewable energy net' or 'bio-energy net' on www.Google.cn. A thorough analysis was conducted by focusing on one of them: www.china5e.com. The news articles on www.china5e.com were examined according to whether the use of bio-energy was articulated positively or negatively in the contents of articles. It was also considered whether the articles were imported from abroad. The results of this study indicated that in China there is a tendency on the Internet to disseminate primarily the positive information about bio-energy with a great emphasis on its benefits. In addition, the study shows that when analyzing the content of the news articles, biogas and liquid bio-fuels will be the main bio-energy development trends in China in the near future. (author)

  3. Innovation, Diffusion, and Regulation in Energy Technologies

    Science.gov (United States)

    Fetter, Theodore Robert

    The innovation and diffusion of new technologies is one of the central concerns of economics. New inventions or technological combinations do not spring fully formed into the world; as firms encounter and learn about new technologies they experiment, refine, and learn about them, improving productivity (and sometimes earning economic rents). Understanding the processes by which firms learn, and how these processes interact with regulations, is fundamental to understanding the emergence of new technologies, their contribution to growth, and the interaction of innovation and regulation. This dissertation addresses how firms learn and respond to regulations in the context of emerging technologies. Within this framework, I address several questions. When production inputs are socially controversial, do firms respond to disclosure laws by voluntarily constraining their inputs? Do these public disclosure laws facilitate knowledge transmission across firms, and if so, what are the implications for public welfare - for instance, do the gains from trade outweigh any effects of reduced incentives for innovation? I study these questions in the context of hydraulic fracturing, though the results offer insight for more general settings. Panning out to a much broader view, I also explore how energy-related technologies - in both generation and consumption - diffuse across national boundaries over time, and whether innovation and diffusion of energy-efficient technologies has led to more or less energy-efficient economic growth. In my first paper, I contribute to improved understanding of the conditions in which information-based regulations, which are increasingly common in multiple policy domains, decrease externalities such as environmental pollution. Specifically, I test whether information disclosure regulations applied to hydraulic fracturing chemicals caused firms to decrease their use of toxic inputs. Prior to these mandatory disclosure laws, some operators voluntarily

    Providing clean water and energy for about nine billion people on the earth by midcentury is a daunting challenge. Major investments in efficiency of energy and water use and deployment of all economical energy sources will be needed. Separations technology has an important role to play in producing both clean energy and water. Some examples are carbon dioxide capture and sequestration from fossil energy power plants and advanced nuclear fuel cycle scemes. Membrane separations systems are under development to improve the economics of carbon capture that would be required at a huge scale. For nuclear fuel cycles, only the PUREX liquid-liquid extraction process has been deployed on a large scale to recover uranium and plutonium from used fuel. Most current R and D on separations technology for used nuclear fuel focuses on ehhancements to a PUREX-type plant to recover the minor actinides (neptunium, americiu, and curium) and more efficiently disposition the fission products. Are there more efficient routes to recycle the actinides on the horizon? Some new approaches and barriers to development will be briefly reviewed.

    Tuberculosis (TB) remains one of the most deadly infections with approximately a quarter of cases not being identified and/or treated mainly due to a lack of resources. Rapid detection of TB or drug-resistant TB enables timely adequate treatment and is a cornerstone of effective TB management. We evaluated the analytical performance of a single-tube assay for multidrug-resistant TB (MDR-TB) on an experimental platform utilising RT-PCR and melting curve analysis that could potentially be operated as a point-of-care (PoC) test in resource-constrained settings with a high burden of TB. Firstly, we developed and evaluated the prototype MDR-TB assay using specimens extracted from well-characterised TB isolates with a variety of distinct rifampicin and isoniazid resistance conferring mutations and nontuberculous Mycobacteria (NTM) strains. Secondly, we validated the experimental platform using 98 clinical sputum samples from pulmonary TB patients collected in high MDR-TB settings. The sensitivity of the platform for TB detection in clinical specimens was 75% for smear-negative and 92.6% for smear-positive sputum samples. The sensitivity of detection for rifampicin and isoniazid resistance was 88.9 and 96.0% and specificity was 87.5 and 100%, respectively. Observed limitations in sensitivity and specificity could be resolved by adjusting the sample preparation methodology and melting curve recognition algorithm. Overall technology could be considered a promising PoC methodology especially in resource-constrained settings based on its combined accuracy, convenience, simplicity, speed, and cost characteristics.

  11. A Technology Platform to Test the Efficacy of Purification of Alginate

    Full Text Available Alginates are widely used in tissue engineering technologies, e.g., in cell encapsulation, in drug delivery and various immobilization procedures. The success rates of these studies are highly variable due to different degrees of tissue response. A cause for this variation in success is, among other factors, its content of inflammatory components. There is an urgent need for a technology to test the inflammatory capacity of alginates. Recently, it has been shown that pathogen-associated molecular patterns (PAMPs in alginate are potent immunostimulatories. In this article, we present the design and evaluation of a technology platform to assess (i the immunostimulatory capacity of alginate or its contaminants, (ii where in the purification process PAMPs are removed, and (iii which Toll-like receptors (TLRs and ligands are involved. A THP1 cell-line expressing pattern recognition receptors (PRRs and the co-signaling molecules CD14 and MD2 was used to assess immune activation of alginates during the different steps of purification of alginate. To determine if this activation was mediated by TLRs, a THP1-defMyD88 cell-line was applied. This cell-line possesses a non-functional MyD88 coupling protein, necessary for activating NF-κB via TLRs. To identify the specific TLRs being activated by the PAMPs, we use different human embryonic kidney (HEK cell-line that expresses only one specific TLR. Finally, specific enzyme-linked immunosorbent assays (ELISAs were applied to identify the specific PAMP. By applying this three-step procedure, we can screen alginate in a manner, which is both labor and cost efficient. The efficacy of the platform was evaluated with an alginate that did not pass our quality control. We demonstrate that this alginate was immunostimulatory, even after purification due to reintroduction of the TLR5 activating flagellin. In addition, we tested two commercially available purified alginates. Our experiments show that these commercial

    Nuclear fission, nuclear fusion, and renewable energy (including biofuels) are the only energy sources capable of satisfying the Earth's need for power for the next century and beyond without the negative environmental impacts of fossil fuels. Substantially increasing the use of nuclear fission and renewable energy now could help reduce dependency on fossil fuels, but nuclear fusion has the potential of becoming the ultimate base-load energy source. Fusion is an attractive fuel source because it is virtually inexhaustible, widely available, and lacks proliferation concerns. It also has a greatly reduced waste impact, and no danger of runaway reactions or meltdowns. The substantial environmental, commercial, and security benefits of fusion continue to motivate the research needed to make fusion power a reality. Replicating the fusion reactions that power the sun and stars to meet Earth's energy needs has been a long-sought scientific and engineering challenge. In fact, this technological challenge is arguably the most difficult ever undertaken. Even after roughly 60 years of worldwide research, much more remains to be learned. the magnitude of the task has caused some to declare that fusion is 20 years away, and always will be. This glib criticism ignores the enormous progress that has occurred during those decades, progress inboth scientific understanding and essential technologies that has enabled experiments producing significant amounts of fusion energy. For example, more than 15 megawatts of fusion power was produced in a pulse of about half a second. Practical fusion power plants will need to produce higher powers averaged over much longer periods of time. In addition, the most efficient experiments to date have required using about 50% more energy than the resulting fusion reaction generated. That is, there was no net energy gain, which is essential if fusion energy is to be a viable source of electricity. The simplest fusion fuels, the heavy isotopes of

    This report summarises and assesses the environmental consequences associated with new energy technologies, with particular emphasis on their use for space heating supplies in the built environment. In the case of solar heating, it is primarily the processes associated with the production of the necessary materials and ground use requirements that can adversely affect the environment. There is also a certain risk associated with the leakage of heat transfer fluid. For heat stores, problem areas are primarily those associated with heating of the ground, discharge of foreign substances in connection with water treatment and conflicts of other users of ground water. The main adverse effects of heat pumps are their emissions of CFCs, which damage the ozone layer, utilisation of certain types of heat sources and the need to provide primary energy for mechanical drive of the pumps. All three of these new energy technologies are regarded as having less environmental consequences than conventional alternatives, although this assumes a change to less hazardous working media in heat pumps. A mutual comparison of the three technologies indicates that solar heating and heat stores have somewhat better environmental characteristics than heat pumps

    The Student Outreach with Renewable Energy Technology (SORET) program is a joint grant that involves a collaboration between three HBCU's (Central State University, Savannah State University, and Wilberforce University) and NASA John H. Glenn Research Center at Lewis Field. The overall goal of the grant is to increase the interest of minority students in the technical disciplines, to encourage participating minority students to continue their undergraduate study in these disciplines, and to promote graduate school to these students. As a part of SORET, Central State University has developed an undergraduate research associates program over the past two years. As part of this program, students are required to take special laboratory courses offered at Wilberforce University that involve the application of renewable energy systems. The course requires the students to design, construct, and install a renewable energy project. In addition to the applied renewable energy course, Central State University provided four undergraduate research associates the opportunity to participate in summer internships at Texas Southern University (Renewable Energy Environmental Protection Program) and the Cleveland African-American Museum (Renewable Energy Summer Camp for High School Students) an activity co sponsored by NASA and the Cleveland African-American Museum. Savannah State University held a high school summer program with a theme of the Direct Impact of Science on Our Every Day Lives. The purpose of the institute was to whet the interest of students in science, mathematics, engineering, and technology (SMET) by demonstrating the effectiveness of science to address real world problems. The 2001 institute involved the design and installation of a PV water pumping system at the Center for Advanced Water Technology and Energy Systems at Savannah State.

    Disaster risk reduction has long been recognized for its role in mitigating the negative environmental, social and economic impacts of natural hazards. Flood Early Warning System is a disaster risk reduction measure based on the capacities of institutions to observe and predict extreme hydro-meteorological events and to disseminate timely and meaningful warning information; it is furthermore based on the capacities of individuals, communities and organizations to prepare and to act appropriately and in sufficient time to reduce the possibility of harm or loss. An operational definition of an Early Warning System has been suggested by ISDR - UN Office for DRR [15 January 2009]: "EWS is the set of capacities needed to generate and disseminate timely and meaningful warning information to enable individuals, communities and organizations threatened by a hazard to prepare and to act appropriately and in sufficient time to reduce the possibility of harm or loss.". ISDR continues by commenting that a people-centered early warning system necessarily comprises four key elements: 1-knowledge of the risks; 2-monitoring, analysis and forecasting of the hazards; 3-communication or dissemination of alerts and warnings; and 4- local capabilities to respond to the warnings received." The technological platform DEWETRA supports the strengthening of the first three key elements of EWS suggested by ISDR definition, hence to improve the capacities to build real-time risk scenarios and to inform and warn the population in advance The technological platform DEWETRA has been implemented for the Republic of Serbia. DEWETRA is a real time-integrate system that supports decision makers for risk forecasting and monitoring and for distributing warnings to end-user and to the general public. The system is based on the rapid availability of different data that helps to establish up-to-date and reliable risk scenarios. The integration of all relevant data for risk management significantly

    Zhou, Yichen Christy

    This dissertation studies technological change in the context of energy and environmental economics. Technology plays a key role in reducing greenhouse gas emissions from the transportation sector. Chapter 1 estimates a structural model of the car industry that allows for endogenous product characteristics to investigate how gasoline taxes, R&D subsidies and competition affect fuel efficiency and vehicle prices in the medium-run, both through car-makers' decisions to adopt technologies and through their investments in knowledge capital. I use technology adoption and automotive patents data for 1986-2006 to estimate this model. I show that 92% of fuel efficiency improvements between 1986 and 2006 were driven by technology adoption, while the role of knowledge capital is largely to reduce the marginal production costs of fuel-efficient cars. A counterfactual predicts that an additional 1/gallon gasoline tax in 2006 would have increased the technology adoption rate, and raised average fuel efficiency by 0.47 miles/gallon, twice the annual fuel efficiency improvement in 2003-2006. An R&D subsidy that would reduce the marginal cost of knowledge capital by 25% in 2006 would have raised investment in knowledge capital. This subsidy would have raised fuel efficiency only by 0.06 miles/gallon in 2006, but would have increased variable profits by 2.3 billion over all firms that year. Passenger vehicle fuel economy standards in the United States will require substantial improvements in new vehicle fuel economy over the next decade. Economic theory suggests that vehicle manufacturers adopt greater fuel-saving technologies for vehicles with larger market size. Chapter 2 documents a strong connection between market size, measured by sales, and technology adoption. Using variation consumer demographics and purchasing pattern to account for the endogeneity of market size, we find that a 10 percent increase in market size raises vehicle fuel efficiency by 0.3 percent, as compared

The mission of the working group is to identify goals and priority ways for the French and European research about the new technologies of energy and to propose some recommendations about the evolution of research incentive and sustain systems in order to reach these goals. The working group has taken into consideration the overall stakes linked with energy and not only the climatic change. About this last point, only the carbon dioxide emissions have been considered because they represent 90% of the greenhouse gases emissions linked with the energy sector. A diagnosis is made first about the present day context inside which the new technologies will have to fit with. Using this diagnosis, the research topics and projects to be considered as priorities for the short-, medium- and long-term have been identified: energy efficiency in transports, in dwellings/tertiary buildings and in the industry, development for the first half of the 21. century of an energy mix combining nuclear, fossil-fuels and renewable energy sources.

The mission of the working group is to identify goals and priority ways for the French and European research about the new technologies of energy and to propose some recommendations about the evolution of research incentive and sustain systems in order to reach these goals. The working group has taken into consideration the overall stakes linked with energy and not only the climatic change. About this last point, only the carbon dioxide emissions have been considered because they represent 90% of the greenhouse gases emissions linked with the energy sector. A diagnosis is made first about the present day context inside which the new technologies will have to fit with. Using this diagnosis, the research topics and projects to be considered as priorities for the short-, medium- and long-term have been identified: energy efficiency in transports, in dwellings/tertiary buildings and in the industry, development for the first half of the 21. century of an energy mix combining nuclear, fossil-fuels and renewable energy sources.

    If nuclear energy is to realize its full potential as a safe and cost-effective alternative to fossil fuels, applications beyond those that are currently being serviced by large, central nuclear power stations must be identified and appropriate reactors developed. The Canadian program on reactor systems for local energy supply is at the forefront of these developments. This program emphasizes design simplicity, low power density and fuel rating, reliance on natural processes, passive systems, and reduced reliance on operator action. The first product, the SLOWPOKE Energy System, is a 10 MW heat source specifically designed to provide hot water to satisfy the needs of local heating systems for building complexes, institutions and municipal district heating systems. A demonstration heating reactor has been constructed at the Whiteshell Nuclear Research Establishment in Manitoba and has been undergoing an extensive test program since first operation in 1987 July. Based on the knowledge learned from the design, construction, licensing and operational testing of this facility, the design of the 10 MW commercial-size unit is well advanced, and Atomic Energy of Canada Limited is prepared to commit the construction of the first commercial unit. Although the technical demonstration of the concept is important, it is recognized that another crucial element is the public and regulatory acceptance of small nuclear systems in urban areas. The decision by a community to commit the construction of a SLOWPOKE Energy System brings to a sharp focus the current public apprehension about nuclear technologies

    Nowadays, it is becoming increasingly common to deploy sensors in public buildings or homes with the aim of obtaining data from the environment and taking decisions that help to save energy. Many of the current state-of-the-art systems make decisions considering solely the environmental factors that cause the consumption of energy. These systems are successful at optimizing energy consumption; however, they do not adapt to the preferences of users and their comfort. Any system that is to be used by end-users should consider factors that affect their wellbeing. Thus, this article proposes an energy-saving system, which apart from considering the environmental conditions also adapts to the preferences of inhabitants. The architecture is based on a Multi-Agent System (MAS), its agents use Agreement Technologies (AT) to perform a negotiation process between the comfort preferences of the users and the degree of optimization that the system can achieve according to these preferences. A case study was conducted in an office building, showing that the proposed system achieved average energy savings of 17.15%.

    Purpose: To develop a robust and efficient platform for the optimization and robotic delivery of highly noncoplanar intensity modulated radiotherapy, which enables significant reduction of normal tissue toxicity and escalation of tumor dose. Methods: An innovative high-output compact 3 MV linac was designed for mounting onto a commercial robotic system in order to access the entire 4π beam solution space without moving the patient couch. The use of intermediate energy X-rays for radiotherapy was evaluated in comparison to clinical plans delivered using 6 MV X-rays and a state-of-the-art delivery system. Monte Carlo simulations of a 3 MV percent depth dose curve were performed for intermediate energy dose calculation. The beam model was used to create a convolution/superposition-based dose calculation engine for 3MV X-rays. The 4π greedy column generation algorithm was used for optimized beam selection and fluence map optimization. Results: A detailed design of the first 3 MV linac capable of producing a competitively high dose rate of >800 cGy/min at 100 cm was completed and verified through extensive simulation. The complete linac head including a multileaf collimator can access most of the 4π solution space including the posterior orientations without changing the couch height. When compared to 6 MV clinical plans, the proposed 3 MV 4π plans demonstrated significantly better dose compactness and normal tissue sparing in brain, prostate, and partial breast treatment plans. Conclusion: We demonstrate the design of a highly versatile radiotherapy machine to natively deliver non-coplanar 4π radiotherapy without the need to move the patient during treatment. This novel platform is efficient and capable of providing dosimetry that is 30–50% more compact than existing therapy platforms. The new system is projected to be cost effective due to improved treatment time and automation. NIH R43CA183390, NIH R01CA188300.

    Industrial application researches utilizing a beam extracting unit and an accelerator with an energy less than 3 MeV have been conducted. Although a number of industrial application areas exist, a few research items had been selected for this project, which include the gemstone coloration and the surface modifications of metals/polymers. In the case of gemstone coloration, the green/yellow colored diamond by a proton beam irradiation and blue color emitting sapphire utilizing Co ion implantation are being evaluated as the high potential for commercialization. And, the band gap structures as a result of impurities' doping was calculated with density functional theory (DFT) and it was found to be well consistent with experimental results. The surface modification of stainless juice extracting gears have been successful and patented, resulting in a technology transfer to the company. The reduction in the detachment of the metallic elements during juice extracting as a results of ion beam surface modification is expected to be broadly applicable to the other relevant industrial materials and parts. In the case of gemstone coloration, it is estimated to be one of the highest commercially valuable items because of its extremely low processing expense. The research results have been successful and is worth while transferring the technologies to the industrial sectors. During the second phase research, 6 SCI papers have been published and 9 patents have been submitted and 3 patents have been registered. 1 technology has been transferred to the company for industrialization and 1 technology is pending for a transference

    The Modular, Reconfigurable High-Energy (MRHE) Technology Demonstrator project was to have been a series of ground-based demonstrations to mature critical technologies needed for in-space assembly of a highpower high-voltage modular spacecraft in low Earth orbit, enabling the development of future modular solar-powered exploration cargo-transport vehicles and infrastructure. MRHE was a project in the High Energy Space Systems (HESS) Program, within NASA's Exploration Systems Research and Technology (ESR&T) Program. NASA participants included Marshall Space Flight Center (MSFC), the Jet Propulsion Laboratory (JPL), and Glenn Research Center (GRC). Contractor participants were the Boeing Phantom Works in Huntsville, AL, Lockheed Martin Advanced Technology Center in Palo Alto, CA, ENTECH, Inc. in Keller, TX, and the University of AL Huntsville (UAH). MRHE's technical objectives were to mature: (a) lightweight, efficient, high-voltage, radiation-resistant solar power generation (SPG) technologies; (b) innovative, lightweight, efficient thermal management systems; (c) efficient, 100kW-class, high-voltage power delivery systems from an SPG to an electric thruster system; (d) autonomous rendezvous and docking technology for in-space assembly of modular, reconfigurable spacecraft; (e) robotic assembly of modular space systems; and (f) modular, reconfigurable distributed avionics technologies. Maturation of these technologies was to be implemented through a series of increasingly-inclusive laboratory demonstrations that would have integrated and demonstrated two systems-of-systems: (a) the autonomous rendezvous and docking of modular spacecraft with deployable structures, robotic assembly, reconfiguration both during assembly and (b) the development and integration of an advanced thermal heat pipe and a high-voltage power delivery system with a representative lightweight high-voltage SPG array. In addition, an integrated simulation testbed would have been developed

    Alternative domestic wastewater treatment processes that recover energy and nutrients while achieving acceptable nutrient limits (650mgCODL(-1). PRR offers the possibility for recovery of nitrogen and other nutrients (including potassium) through assimilative recovery. However, the energetic overhead of this is substantial, requiring 5kWhkgN(-1) as electricity, which compares to ammonia fixation costs. The lower energy costs, and near to market status of LEM treatment make it likely as a recovery platform in the shorter term, while ability to recover other elements such as nitrogen and potassium, as well as enhance favourability on concentrated wastewaters may enhance the desirability of partitioning in the longer term.

    Despite the present gloom surrounding the nuclear option for electricity and heat generation, there are still people in Switzerland in industry, research, banking and even politics willing and capable to think in terms of long-range projections. The basis for these projections is the belief that a well-functioning and prosperous society always needs large and reliable sources of acceptably priced energy, which must be generated with a high respect for the necessity of a clean environment. Being aware of the current low acceptance level of the nuclear option, efforts to keep this option open are directed to achieving the following goals: to maintain and improve the country's capabilities to safely operate the four existing nuclear power plants of Beznau (twin units), Muehleberg, Goesgen and Leibstadt; to keep the capability of extending the applications of nuclear energy technology. In practice, this could be in the fields of district heating, fusion, and advanced power reactors

    The companies that are working in decontamination, dismantling and assessment in nuclear power plants, usually have their employees in different facilities far from its central offices. When there is a training in radiological protection applied to the nuclear field, it is difficult for these people the attendance to the course because of different reasons as the location of the formation centres which sometimes are not near from the nuclear facilities, so they usually cannot attend their daily work with the same effectiveness. In this work we present a postgraduate training in radiological protection supervised by Polytechnical University of Valencia (Spain) applied to nuclear and radioactive facilities by a technological platform developed in collaboration with the university. This platform is adapted and designed to different high level contents and applications in different areas and sections, related to a general part, radioactive facilities, nuclear facilities and advanced concepts. When the student finishes an area, an evaluation has to be done to prove the understanding of the lessons. We have included films of different activities as decontamination devices, radiation detectors..etc with the contents to make the explanations more understandable to the student. The course is complemented with a final review and exam that are not online to guarantee that the training is well finished. In addition the student has some practice related with different items explained during the training as the use of equipment in radiological protection tasks. This type of training is more flexitime and can be adapted to the necessities of each user, avoiding high costs and unnecessary displacements. (author)

    1995-12-01

    Increasing interest in biomass energy conversion in recent years has focused attention on enhancing the efficiency of technologies converting biomass fuels into heat and power, their capital and operating costs and their environmental emissions. Conventional combustion systems, such as fixed-bed or grate units and entrainment units, deliver lower efficiencies (<25%) than modem coal-fired combustors (30-35%). The gasification of biomass will improve energy conversion efficiency and yield products useful for heat and power generation and chemical synthesis. Advanced biomass gasification technologies using pressurized fluidized-bed systems, including those incorporating hot-gas clean-up for feeding gas turbines or fuel cells, are being demonstrated. However, many biomass gasification processes are derivatives of coal gasification technologies and do not exploit the unique properties of biomass. This paper examines some existing and upcoming technologies for converting biomass into electric power or heat. Small-scale 1-30 MWe units are emphasized, but brief reference is made to larger and smaller systems, including those that bum coal-biomass mixtures and gasifiers that feed pilot-fuelled diesel engines. Promising advanced systems, such as a biomass integrated gasifier/gas turbine (BIG/GT) with combined-cycle operation and a biomass gasifier coupled to a fuel cell, giving cycle efficiencies approaching 50% are also described. These advanced gasifiers, typically fluid-bed designs, may be pressurized and can use a wide variety of biomass materials to generate electricity, process steam and chemical products such as methanol. Low-cost, disposable catalysts are becoming available for hot-gas clean-up (enhanced gas composition) for turbine and fuel cell systems. The advantages, limitations and relative costs of various biomass gasifier systems are briefly discussed.

    2009-03-01

    In the next few years political decisions lie ahead in Sweden and the EU regarding the detailed formulation of the EU's so-called 20-20-20 targets and accompanying EU directives. Talks on a new international post-2012 climate agreement are imminent. The EU targets involve reducing emissions of greenhouse gases by 20 per cent, increasing the proportion of renewable energy by 20 per cent and improving energy efficiency by 20 per cent - all by the year 2020. According to the analysis of the consequences of the targets that the Technology Development Group has commissioned, the reduction in carbon dioxide in the stationary energy system in the Nordic region will be 40 per cent, not 20 per cent, if all the EU targets are to be achieved. The biggest socio-economic cost is associated with achieving the efficiency target, followed by the costs associated with achieving the renewable energy target and the CO 2 target. On the basis of this analysis and compilations about technology development, we want to highlight the following important key issues: Does Sweden want to have the option of nuclear power in the future or not? How to choose good policy instruments for new electricity production and networks? How best to reduce the carbon dioxide emissions of the transport sector and how to develop control and incentive measures that promote such a development? We are proposing the following: Carry out a more in-depth analysis of the consequences of the EU targets, so that the policy instruments produce the best combination as regards climate, economy and security of supply. To achieve the EU targets would require large investments in electricity production, particularly renewable energy, and in electricity networks. Internationally harmonized policy instruments and other incentive measures are required in order for the necessary investments to take place. The policy instruments have to provide a level playing field for all players in the energy sector. The large investments

    This report proposes solar energy utilizing technologies for future cities, centering on a system that uses Fresnel lenses and optical fiber cables. This system selects out beams in the visible range and the energy can be sent to end terminals constantly as long as sunlight is available. Optical energy is concentrated 4,000-fold. The system can provide long-distance projection of parallel rays. It will be helpful for efficient utilization of light in cities and can increase the degree of freedom in carrying out urban development. The total efficiency for the introduction into optical fiber can be up to 40 percent. With no heating coil incorporated, there is no danger of fire. The standard size of a light condenser is 2 m in dome diameter and 2.5 m in height. Auxiliary artificial light is used for backup purposes when it is cloudy. Heat pumps operating on solar thermal energy are employed to maintain air conditioning for 24 hours a day in order to ensure the establishment of an environment where residential areas exist in the neighborhood of office areas. Seven automatic solar light collection and transfer systems are currently in practical use at the Arc Hills building. The combination of Fresnel lens and optical fiber is more than six times as high in efficiency as a reflecting mirror. (5 figs, 3 tabs, 8 photos, 6 refs)

Several initial screening criteria were used to identify promising ATES applications. These include the existence of an energy availability/usage mismatch, the existence of many similar applications or commercial sites, the ability to utilize proven technology, the type of location, market characteristics, the size of and access to capital investment, and the number of decision makers involved. The in-depth analysis identified several additional screening criteria to consider in the selection of an entry market application. This analysis revealed that the best initial applications for ATES are those where reliability is acceptable, and relatively high temperatures are allowable. Although chill storage was the primary focus of this study, applications that are good candidates for heat ATES were also of special interest. 11 refs., 3 tabs.

    Purpose of the report is to provide information about the electricity-saving potential of new technologies to OCEP that it can use in developing alternative long-term projections of US electricity consumption. Low-, base-, and high-case scenarios of the electricity savings for ten technologies were prepared. The total projected annual savings for the year 2000 for all ten technologies were 137 billion kilowatt hours (BkWh), 279 BkWh, and 470 BkWh, respectively, for the three cases. The magnitude of these savings projections can be gauged by comparing them to the Department's reference case projection for the 1985 National Energy Policy Plan. In the Department's reference case, total consumption in 2000 is projected to be 3319 BkWh. Thus, the savings projected here represent between 4% and 14% of total consumption projected for 2000. Because approximately 75% of the base-case estimate of savings are already incorporated into the reference forecast, reducing projected electricity consumption from what it otherwise would have been, the savings estimated here should not be directly subtracted from the reference forecast.

    The National Aeronautics and Space Administration is developing battery and fuel cell technology to meet the expected energy storage needs of human exploration systems. Improving battery performance and safety for human missions enhances a number of exploration systems, including un-tethered extravehicular activity suits and transportation systems including landers and rovers. Similarly, improved fuel cell and electrolyzer systems can reduce mass and increase the reliability of electrical power, oxygen, and water generation for crewed vehicles, depots and outposts. To achieve this, NASA is developing non-flow-through proton-exchange-membrane fuel cell stacks, and electrolyzers coupled with low permeability membranes for high pressure operation. The primary advantage of this technology set is the reduction of ancillary parts in the balance-of-plant fewer pumps, separators and related components should result in fewer failure modes and hence a higher probability of achieving very reliable operation, and reduced parasitic power losses enable smaller reactant tanks and therefore systems with lower mass and volume. Key accomplishments over the past year include the fabrication and testing of several robust, small-scale non-flow-through fuel cell stacks that have demonstrated proof-of-concept. NASA is also developing advanced lithium-ion battery cells, targeting cell-level safety and very high specific energy and energy density. Key accomplishments include the development of silicon composite anodes, lithiatedmixed- metal-oxide cathodes, low-flammability electrolytes, and cell-incorporated safety devices that promise to substantially improve battery performance while providing a high level of safety.

    Full Text Available The HEAT (Home Energy Assessment Technologies pilot project is a FREE Geoweb mapping service, designed to empower the urban energy efficiency movement by allowing residents to visualize the amount and location of waste heat leaving their homes and communities as easily as clicking on their house in Google Maps. HEAT incorporates Geospatial solutions for residential waste heat monitoring using Geographic Object-Based Image Analysis (GEOBIA and Canadian built Thermal Airborne Broadband Imager technology (TABI-320 to provide users with timely, in-depth, easy to use, location-specific waste-heat information; as well as opportunities to save their money and reduce their green-house-gas emissions. We first report on the HEAT Phase I pilot project which evaluates 368 residences in the Brentwood community of Calgary, Alberta, Canada, and describe the development and implementation of interactive waste heat maps, energy use models, a Hot Spot tool able to view the 6+ hottest locations on each home and a new HEAT Score for inter-city waste heat comparisons. We then describe current challenges, lessons learned and new solutions as we begin Phase II and scale from 368 to 300,000+ homes with the newly developed TABI-1800. Specifically, we introduce a new object-based mosaicing strategy, an adaptation of Emissivity Modulation to correct for emissivity differences, a new Thermal Urban Road Normalization (TURN technique to correct for scene-wide microclimatic variation.

    Full Text Available Limited battery energy restricts the duration of the underwater operation of underwater mooring platforms (UMPs. In this paper, a flow-induced vibration energy converter (FIVEC is designed to produce power for the UMPs and extend their operational time. The FIVEC is equipped with a thin plate to capture the kinetic energy in the vortices shed from the surface of the UMP. A magnetic coupling (MC is applied for the non-contacting transmission of the plate torque to the generators so that the friction loss can be minimized. In order to quantify and evaluate the performance of the FIVEC, two-dimensional computational fluid dynamics (CFD simulations are performed. Simulations are based on the Reynolds Averaged Navier-Stokes (RANS equations and the shear stress transport (SST k-ω turbulent model is utilized. The CFD method is firstly validated using existing experimental data. Then the influences of plate length and system damping on the performance of the FIVEC are evaluated. The results show that the device has a maximum averaged power coefficient of 0.0520 (13.86 W in the considered situations. The results also demonstrate the feasibility of this energy converter plan.

    We present and apply a new method for analyzing the significance of advanced technology for achieving two important national energy goals: climate protection and energy security. Quantitative metrics for U.S. greenhouse gas emissions in 2050 and oil independence in 2030 are specified, and the impacts of 11 sets of energy technologies are analyzed using a model that employs the Kaya identity and incorporates the uncertainty of technological breakthroughs. The goals examined are a 50% to 80% reduction in CO2 emissions from energy use by 2050 and increased domestic hydrocarbon fuels supply and decreased demand that sum to 11 mmbd by 2030. The latter is intended to insure that the economic costs of oil dependence are not more than 1% of U.S. GDP with 95% probability by 2030. Perhaps the most important implication of the analysis is that meeting both energy goals requires a high probability of success (much greater than even odds) for all 11 technologies. Two technologies appear to be indispensable for accomplishment of both goals: carbon capture and storage, and advanced fossil liquid fuels. For reducing CO2 by more than 50% by 2050, biomass energy and electric drive (fuel cell or battery powered) vehicles also appear to be necessary. Every one of the 11 technologies has a powerful influence on the probability of achieving national energy goals. From the perspective of technology policy, conflict between the CO2 mitigation and energy security is negligible. These general results appear to be robust to a wide range of technology impact estimates; they are substantially unchanged by a Monte Carlo simulation that allows the impacts of technologies to vary by 20%.

    The prospects for the future use of nuclear energy worldwide can best be understood within the context of global population growth, urbanization, rising energy need and associated pollution concerns. As the world continues to urbanize, sustainable development challenges are expected to be concentrated in cities of the lower-middle-income countries where the pace of urbanization is fastest. As these countries continue their trajectory of economic development, their energy need will also outpace their population growth adding to the increased demand for electricity. OECD IEA's energy system deployment pathway foresees doubling of the current global nuclear capacity by 2050 to reduce the impact of rapid urbanization. The pending "retirement cliff" of the existing U.S. nuclear fleet, representing over 60 percent of the nation's emission-free electricity, also poses a large economic and environmental challenge. To meet the challenge, the U.S. DOE has developed the vision and strategy for development and deployment of advanced reactors. As part of that vision, the U.S. government pursues programs that aim to expand the use of nuclear power by supporting sustainability of the existing nuclear fleet, deploying new water-cooled large and small modular reactors to enable nuclear energy to help meet the energy security and climate change goals, conducting R&D for advanced reactor technologies with alternative coolants, and developing sustainable nuclear fuel cycle strategies. Since the current path relying heavily on water-cooled reactors and "once-through" fuel cycle is not sustainable, next generation nuclear energy systems under consideration aim for significant advances over existing and evolutionary water-cooled reactors. Among the spectrum of advanced reactor options, closed-fuel-cycle systems using reactors with fast-neutron spectrum to meet the sustainability goals offer the most attractive alternatives. However, unless the new public-private partnership models emerge

    X-ray opacity is a crucial factor in all radiation-hydrodynamics calculations, yet it is one of the least validated of the material properties in simulation codes for high-energy-density plasmas. Recent opacity experiments at the Sandia Z-machine have shown up to factors of two discrepancies between theory and experiment for various mid-Z elements (Fe, Cr, Ni). These discrepancies raise doubts regarding the accuracy of the opacity models which are used in ICF and stewardship as well as in astrophysics. Therefore, a new experimental opacity platform has been developed on the National Ignition Facility (NIF), not only to verify the Z-machine experimental results, but also to extend the experiments to other temperatures and densities. Within the context of the national opacity strategy, the first NIF experiments were directed towards measuring the opacity of iron at a temperature of ~160 eV and an electron density of ~7xl021 cm-3(Anchor 1). The Z data agree with theory at these conditions, providing a reference point for validation of the NIF platform. Development shots on NIF have demonstrated the ability to create a sufficiently bright point backlighter using an imploding plastic capsule, and also a combined hohlraum, sample and laser drive able to produce iron plasmas at the desired conditions. Spectrometer qualification has been completed, albeit with additional improvements planned, and the first iron absorption spectra have now been obtained.

    The effect of complex biological fluids on the surface and structure of nanoparticles is a rapidly expanding field of study. One of the challenges holding back this research is the difficulty of recovering therapeutic nanoparticles from biological samples due to their small size, low density, and stealth surface coatings. Here, the first demonstration of the recovery and analysis of drug delivery nanoparticles from undiluted human plasma samples through the use of a new electrokinetic platform technology is presented. The particles are recovered from plasma through a dielectrophoresis separation force that is created by innate differences in the dielectric properties between the unaltered nanoparticles and the surrounding plasma. It is shown that this can be applied to a wide range of drug delivery nanoparticles of different morphologies and materials, including low-density nanoliposomes. These recovered particles can then be analyzed using different methods including scanning electron microscopy to monitor surface and structural changes that result from plasma exposure. This new recovery technique can be broadly applied to the recovery of nanoparticles from high conductance fluids in a wide range of applications. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    2017-01-01

    This study examines how political, social and economic factors influence clean energy technology entrepreneurship (CETE). Government policies supporting clean energy technology development and the development of markets for clean energy create opportunities for CETE. However, the extent to which such opportunities lead to the emergence of new clean energy businesses depends on a favorable external context promoting CETE. This study employs a novel dataset combining indicators of the policy and social context of CETE with information on clean energy technology startup firms in the USA to provide empirical evidence that technological and market conditions supporting clean energy induce more extensive CETE under contexts where local attention to clean energy issues and successful firms commercializing clean energy technologies are more prominent. By establishing that CETE is contingent upon a supportive local environment as well as technology and market opportunities, the study holds relevance for policy makers and clean energy technology firms. - Highlights: • Influence of political, social and economic factors on clean energy technology entrepreneurship (CETE). • CETE more prominent with clean energy technology availability. • Greater when local attention interacts with technology availability and market opportunities. • Greater when local firms successfully commercialize technologies. • Novel dataset and Arellano-Bond dynamic panel estimation.

    For this project, the intended goal of the microgrid component was to investigate issues in policy and technology that would drive higher penetration of renewable energy, and to demonstrate implementation in a utility system. The work accomplished on modeling the dynamics of photovoltaic (PV) penetration can be expanded for practical application. Using such a tool those involved in public policy can examine what the effect of a particular policy initiative, e.g., renewable portfolio standards (RPS) requirements, might be in terms of the desired targets. The work in the area of microgrid design, protection, and operation is fundamental to the development of microgrids. In particular the “Energy Delivery” paradigm provides new opportunities and business models for utilities. Ultimately, Energy Delivery could accrue significant benefits in terms of costs and resiliency. The experimental microgrid will support continued research and allow the demonstration of technology for better integration of renewables. The algal biofuels component of the project was developed to enhance the test facility and to investigate the technical and economic feasibility of a commercial-scale geothermal algal biofuels operation for replication elsewhere in the arid Southwest. The project was housed at New Mexico State University’s (NMSU’s) Geothermal Aquaculture Facility (GAF) and a design for the inoculation train and algae grow-out process was developed. The facility was upgraded with modifications to existing electrical, plumbing and structural components on the GAF and surrounding grounds. The research work was conducted on biomass-processing, harvesting, dewatering, and extraction. Additionally, research was conducted to determine viability of using low-cost, wastewater from municipal treatment plants in the cultivation units as make-up water and as a source of nutrients, including nitrogen and soluble phosphorus. Data was collected on inputs and outputs, growth evaluation and

    Challenges with cost, cyclability, and/or low energy density have largely prevented the development of solar thermal fuels, a potentially attractive alternative energy technology based on molecules that can capture and store solar energy as latent heat in a closed cycle. In this paper, we present a set of novel hybrid photoisomer/template solar thermal fuels that can potentially circumvent these challenges. Using first-principles computations, we demonstrate that these fuels, composed of organic photoisomers bound to inexpensive carbon-based templates, can reversibly store solar energy at densities comparable to Li-ion batteries. Furthermore, we show that variation of the template material in combination with the photoisomer can be used to optimize many of the key performance metrics of the fuel-i.e., the energy density, the storage lifetime, the temperature of the output heat, and the efficiency of the solar-to-heat conversion. Our work suggests that the solar thermal fuels concept can be translated into a practical and highly customizable energy storage and conversion technology.

    According to a recent study, global wind generating capacity increased by some 6800 MW in 2001, an annual growth of just over half the corresponding figure for 2000. 2001 was the third consecutive year in which new wind power capacity exceeded new nuclear power capacity, showing the maturity of wind power technology. Total installed wind power worldwide by the end of 2001 was close to 25.000 MW. Germany, Spain and Denmark are the main players, accounting for 56% of the world's capacity increase in 2001 and a total cumulative installed capacity of 14.750 MW, or 59% of the global total. The USA and India are also significant users of wind power; in 2001 the USA added 1700 MW of new installed capacity to become the world's second-largest market for wind power. The report Wind Force 10 outlines a scenario in which wind power provides 10% of the world's electricity by 2020, corresponding to a total installed capacity of 1200 GW. Risoe's System Analysis Department has looked at the possible future costs of electricity produced by wind turbines compared to conventional power. A learning curve analysis of historical data results in a progress ratio of 0,85. This means that for every doubling of the installed capacity, the cost of wind-generated electricity is reduced by 15%. Until recently the main driver for wind power has been a concern for greenhouse gases. Security of energy supply has now become an important issue, however, especially in Europe and the USA. Wind power plants can be erected at short notice and in a modular fashion that allows capacity to be added as required. The European Commission has supported wind power by sponsoring international research co-operation between institutes, universities and equipment manufacturers.

    To satisfy the requirements of surface and atomic physics study in the field of low energy multiple charge state ion incident experiments, a low energy (10 eV/q-20 keV/q) ion beam platform is under design at IMP. A simple test bench has been set up to test the ion beam deceleration systems. Considering virtues such as structure simplicity, easy handling, compactness, cost saving, etc., an all-permanent magnet ECRIS LAPECR1 [Lanzhou all-permanent magnet electron cyclotron resonance (ECR) ion source No. 1] working at 14.5 GHz has been adopted to produce intense medium and low charge state ion beams. LAPECR1 source has already been ignited. Some intense low charge state ion beams have been produced on it, but the first test also reveals that many problems are existing on the ion beam transmission line. The ion beam transmission mismatches result in the depressed performance of LAPECR1, which will be discussed in this paper. To obtain ultralow energy ion beam, after being analyzed by a double-focusing analyzer magnet, the selected ion beam will be further decelerated by two afocal deceleration lens systems, which is still under design. This design has taken into consideration both ions slowing down and also ion beam focusing. In this paper, the conceptual design of deceleration system will be discussed

This design has taken into consideration both ions slowing down and also ion beam focusing. In this paper, the conceptual design of deceleration system will be discussed.

    Given proper care in siting, design, deployment, operation and maintenance, marine and hydrokinetic technologies could become one of the more environmentally benign sources of electricity generation. In order to accelerate the adoption of these emerging hydrokinetic and marine energy technologies, navigational and environmental concerns must be identified and addressed. All developing hydrokinetic projects involve a wide variety of stakeholders. One of the key issues that site developers face as they engage with this range of stakeholders is that many of the possible conflicts (e.g., shipping and fishing) and environmental issues are not well-understood, due to a lack of technical certainty. In September 2008, re vision consulting, LLC was selected by the Department of Energy (DoE) to apply a scenario-based approach to the emerging wave and tidal technology sectors in order to evaluate the impact of these technologies on the marine environment and potentially conflicting uses. The project’s scope of work includes the establishment of baseline scenarios for wave and tidal power conversion at potential future deployment sites. The scenarios will capture variations in technical approaches and deployment scales to properly identify and characterize environmental impacts and navigational effects. The goal of the project is to provide all stakeholders with an improved understanding of the potential effects of these emerging technologies and focus all stakeholders onto the critical issues that need to be addressed. This groundwork will also help in streamlining siting and associated permitting processes, which are considered key hurdles for the industry’s development in the U.S. today. Re vision is coordinating its efforts with two other project teams funded by DoE which are focused on regulatory and navigational issues. The results of this study are structured into three reports: 1. Wave power scenario description 2. Tidal power scenario description 3. Framework for

    For the 40-plus years of the Cold War, both the United States and the Soviet Union built up nuclear stockpiles of tens of thousands of weapons. Now, as the Cold War has ended and tensions between the superpowers have subsided, the US faces the task of significantly reducing its nuclear arsenal. Many thousands of nuclear weapons are being removed from the stockpile as a result of recent treaties and unilateral decisions. This issue of Energy and Technology Review describes the Laboratory`s role in the nation`s effort to dismantle these weapons safely and rapidly. The dismantlement of the United States` nuclear weapons takes place at the Department of Energy`s Pantex facility near Amarillo, Texas. The first article in this issue summarizes the Laboratory`s involvement in dismantling Livermore-designed nuclear weapons. LLNL (like Los Alamos) has responsibility for the weapons it designed, from design concept to retirement. In the past, the responsibilities ended when the weapon was retired from the stockpile. Now however, the role has been extended to include dismantlement. The second article reports on an incident that occurred in November 1992, in which the pit of a W48 warhead cracked during dismantlement. The Laboratory was called upon to handle the pit safely and determine the causes of the cracking. The third article explores a variety of methods proposed for reusing the high explosives after they are removed from the weapon. In the past, Laboratory work on nuclear weapons focused primarily on design and development. However, as the size and composition of the US stockpile changes with evolving international conditions, they will be called upon with increasing frequency to provide the scientific and technical expertise needed to dismantle the nation`s retired nuclear weapons safely and efficiently.

    This paper investigates empirically the effect of market regulation and renewable energy policies on innovation activity in different renewable energy technologies. For the EU countries and the years 1980 to 2007, we built a unique dataset containing information on patent production in eight different technologies, proxies of market regulation and technology-specific renewable energy policies. Our main findings show that lowering entry barriers is a more significant driver of renewable energy innovation than privatisation and un-bundling, but its effect varies across technologies, being stronger in technologies characterised by the potential entry of small, independent power producers. Additionally, the inducement effect of renewable energy policies is heterogeneous and more pronounced for wind, which is the only technology that is mature and has high technological potential. Finally, the ratification of the Kyoto protocol - determining a more stable and less uncertain policy framework - amplifies the inducement effect of both energy policy and market liberalisation.

    Full Text Available Environmental friendly renewable energy plays an indispensable role in energy industry development. Foreign direct investment (FDI in advanced renewable energy technology spillover is promising to improve technological capability and promote China’s energy industry performance growth. In this paper, the impacts of FDI renewable energy technology spillover on China’s energy industry performance are analyzed based on theoretical and empirical studies. Firstly, three hypotheses are proposed to illustrate the relationships between FDI renewable energy technology spillover and three energy industry performances including economic, environmental, and innovative performances. To verify the hypotheses, techniques including factor analysis and data envelopment analysis (DEA are employed to quantify the FDI renewable energy technology spillover and the energy industry performance of China, respectively. Furthermore, a panel data regression model is proposed to measure the impacts of FDI renewable energy technology spillover on China’s energy industry performance. Finally, energy industries of 30 different provinces in China based on the yearbook data from 2005 to 2011 are comparatively analyzed for evaluating the impacts through the empirical research. The results demonstrate that FDI renewable energy technology spillover has positive impacts on China’s energy industry performance. It can also be found that the technology spillover effects are more obvious in economic and technological developed regions. Finally, four suggestions are provided to enhance energy industry performance and promote renewable energy technology spillover in China.

    Can renewable energy technologies meet various consumption needs? It may be argued that without commercial viability, renewable energy technologies cannot compete with conventional energy technologies in this respect. The following issues are to be examined in this paper: (1) the types of renewable energy technologies needed in relation to consumption needs; (2) whether these technologies are commercially viable; (3) the extent to which these technologies can supply the energy needed for industrialisation and economic development in developing countries; (4) policy implications of commercialising renewable energy technologies; and, (5) the role of Asia-Europe cooperation on technological development, diffusion and transfer. The evaluation will concentrate on market potential rather than technological potential, as some of the renewable energy technologies are yet to be commercial. This examination will be made in the context of the specific consumption needs of a major developing country like China in its current period of high economic growth rates and rapid industrialisation. Asia-Europe co-operation on renewable energy technologies can speed up the process of commercialisation through demonstration, direct investment, joint venture, Build-Operate-Transfer (BOT), financial aid and capacity building (both technological know-how and institutional)

    Climate scientists have been using for decades either remotely observed data, mainly from (un)manned aircraft and satellites, or ground-based measurements. High-Altitude Pseudo Satellites (HAPS) are emerging as a disruptive technology that will be used for various "Near Space" applications at altitudes between 15 and 23 km (i.e. above commercial airlines). This new generation of electric solar-powered unmanned aerial vehicles flying in the stratosphere aim to persistently monitor regional areas (with high temporal, spatial and spectral resolution) as well as perform in-situ Near Space observations. The two case studies presented will highlight the advantages of using such an innovative platform. First, calculations were performed to compare the use of a constellation of Low Earth Orbit satellites and a fleet of HAPS for surface monitoring. Using stratospheric drones has a clear advantage for revisiting a large zone (10'000km2 per day) with higher predictability and accuracy. User is free to set time over a location, avoid cloud coverage and obtain Ground Sampling Distance of 30cm using commercially of the shelf sensors. The other impact study focuses on in-situ measurements. Using HAPS will indeed help to closely observe stratospheric compounds, such as aerosols or volcano plumes. Simulations were performed to show how such a drone could collect samples and provide high-accuracy evaluations of compounds that, so far, are only remotely observed. The performed impact studies emphasize the substantial advantages of using HAPS for future stratospheric campaigns. Deploying month-long unmanned missions for monitoring stratospheric aerosols will be beneficial for future research projects such as climate engineering.

    Microalgae is considered a promising source for biofuel and bioenergy production, bio-remediation and production of high-value bioactive compounds, but harvesting microalgae is a major bottleneck in the algae based processes. The objective of this research is to mimic the growth of natural lichen and develop a novel biofilm platform technology using filamentous fungi and microalgae to form a lichen type of biofilm "mycoalgae" in a supporting polymer matrix. The possibility of co-existence of Chlorella vulgaris with various fungal cultures was tested to identify the best strain combination for high algae harvest efficiency. The effect of different matrices for cell attachment and biofilm formation, cell surface characterization of mycoalgae biofilm, kinetics of the process with respect to the algae-fungi cell distribution and total biomass production was studied. Mycoalgae biofilm with algae attachment efficiency of 99.0 % and above was achieved in a polymer-cotton composite matrix with glucose concentration of 2 g/L in the growth medium and agitation intensity of 150 rpm at 27 °C. The total biomass in the co-culture with the selected strain combination (Mucor sp. and Chlorella sp.) was higher than the axenic cultures of fungi and algae at the conditions tested. The results show that algae can be grown with complete attachment to a bio-augmenting fungal surface and can be harvested readily as a biofilm for product extraction from biomass. Even though, interaction between heterotrophic fungi and phototrophic algae was investigated in solid media after prolonged contact in a report, this research is the first of its kind in developing an artificial lichen type biofilm called "mycoalgae" biofilm completely attached on a matrix in liquid cultures. The mycoalgae biofilm based processes, propounds the scope for exploring new avenues in the bio-production industry and bioremediation.

    The likelihood of intentional and unintentional engineered nanoparticle (ENP) exposure has dramatically increased due to the use of nanoenabled products. Indeed, ENPs have been incorporated in many useful products and have enhanced our way of life. However, there are many unanswered questions about the consequences of nanoparticle exposures, in particular, with regard to their potential to damage the genome and thus potentially promote cancer. In this study, we present a high-throughput screening assay based upon the recently developed CometChip technology, which enables evaluation of single-stranded DNA breaks, abasic sites, and alkali-sensitive sites in cells exposed to ENPs. The strategic microfabricated, 96-well design and automated processing improves efficiency, reduces processing time, and suppresses user bias in comparison to the standard comet assay. We evaluated the versatility of this assay by screening five industrially relevant ENP exposures (SiO2, ZnO, Fe2O3, Ag, and CeO2) on both suspension human lymphoblastoid (TK6) and adherent Chinese hamster ovary (H9T3) cell lines. MTT and CyQuant NF assays were employed to assess cellular viability and proliferation after ENP exposure. Exposure to ENPs at a dose range of 5, 10, and 20 μg/mL induced dose-dependent increases in DNA damage and cytotoxicity. Genotoxicity profiles of ZnO>Ag>Fe2O3>CeO2>SiO2 in TK6 cells at 4 h and Ag>Fe2O3>ZnO>CeO2>SiO2 in H9T3 cells at 24 h were observed. The presented CometChip platform enabled efficient and reliable measurement of ENP-mediated DNA damage, therefore demonstrating the efficacy of this powerful tool in nanogenotoxicity studies.

    As an important part of IoTization trends, wireless sensing technologies have been involved in many fields of human life. In cellular network evolution, the long term evolution advanced (LTE-A) networks including machine-type communication (MTC) features (named LTE-M) provide a promising infrastructure for a proliferation of Internet of things (IoT) sensing platform. However, LTE-M may not be optimally exploited for directly supporting such low-data-rate devices in terms of energy efficiency since it depends on core technologies of LTE that are originally designed for high-data-rate services. Focusing on this circumstance, we propose a novel adaptive modulation and coding selection (AMCS) algorithm to address the energy consumption problem in the LTE-M based IoT-sensing platform. The proposed algorithm determines the optimal pair of MCS and the number of primary resource blocks (#PRBs), at which the transport block size is sufficient to packetize the sensing data within the minimum transmit power. In addition, a quantity-oriented resource planning (QORP) technique that utilizes these optimal MCS levels as main criteria for spectrum allocation has been proposed for better adapting to the sensing node requirements. The simulation results reveal that the proposed approach significantly reduces the energy consumption of IoT sensing nodes and #PRBs up to 23.09% and 25.98%, respectively.

    While the energy crisis of the 1970s stimulated technological innovation in developed countries, it often had the opposite effect in the third world. However, developing countries can be considered to have two types of energy systems: ''connected'' and ''disconnected''. The connected system is affected by changes in the price of commercial energy, but the disconnected system is usually rural and remote. Commercial forms of energy may be needed in the disconnected system, but they are largely unavailable. In some of the developing countries, new energy technologies have therefore been developed which adapt traditional technologies still existing in the disconnected sector. In this article some of the work of the United National Centre for Science and Technology for Development is described. Through its ATAS (Advance Technology Alert System) programme, international and regional workshops are held to discuss policy questions arising in regard to new technologies and developments. Workshops have been held in Moscow on new energy technologies in the industry subsystem (connected), in Guatemala City on new energy technologies and the disconnected system, and in Ottawa on new energy technologies, transportation and development. Initial assessments made by or through these workshops are outlined here. A fourth workshop will be held in June 1990 in Saarbrucken on energy technologies and climate change. (author). 3 figs

    With the increased market-orientation and privatisation of the energy area, the perspective of innovation is becoming more and more relevant for understanding the dynamics of change and technology development in the area. A better understanding of the systemic and complex processes of innovation is needed. This paper presents an innovation systems analysis of new and emerging energy technologies in Denmark. The study focuses on five technology areas: bio fuels, hydrogen technology, wind energy, solar cells and energy-efficient end-use technologies. The main result of the analysis is that the technology areas are quite diverse in a number of innovation-relevant issues like actor set-up, institutional structure, maturity, and connections between market and non-market aspects. The paper constitutes background for discussing the framework conditions for transition to sustainable energy technologies and strengths and weaknesses of the innovation systems. (au)
