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.

2000-06-16

The Department of Energy's (DOE) Office of Science and Technology Decontamination and Decommissioning (D&D) Focus Area, led by the National Energy Technology Laboratory, has been charged with finding new and innovative D&D technologies and then validating through field demonstration that the technologies are safer, faster and/or more cost-effective. The D&D Focus Area's approach to verifying the benefits of the improved D&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&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&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.

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.

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

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

1992-12-01

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

Full Text Available Cross-platform - a concept becoming increasingly used in recent years especially in the development of mobile apps, but this consistently over time and in the development of conventional desktop applications. The notion of cross-platform software (multi-platform or platform-independent refers to a software application that can run on more than one operating system or computing architecture. Thus, a cross-platform application can operate independent of software or hardware platform on which it is execute. As a generic definition presents a wide range of meanings for purposes of this paper we individualize this definition as follows: we will reduce the horizon of meaning and we use functionally following definition: a cross-platform application is a software application that can run on more than one operating system (desktop or mobile identical or in a similar way.

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

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.

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 ).

Energy modelling platforms for policy and strategy support

International Nuclear Information System (INIS)

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.

Braff, Dana; Shis, David; Collins, James J

2016-10-01

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.

Gibbs, Gerard; Clark, Stella; Quinn, Julieanne; Gleeson, Mary Joy

2010-04-01

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.

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.

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

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.

Technology Roadmaps: How2Guide for Wind Energy Roadmap

Energy Technology Data Exchange (ETDEWEB)

NONE

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

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.

Emerging Energy-Efficient Technologies in Buildings Technology Characterizations for Energy Modeling

Energy Technology Data Exchange (ETDEWEB)

Hadley, SW

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

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

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.

Energy research and energy technology

1991-01-01

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.

Adaptive MCS selection and resource planning for energy-efficient communication in LTE-M based IoT sensing platform.

Dao, Nhu-Ngoc; Park, Minho; Kim, Joongheon; Cho, Sungrae

2017-01-01

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.

2013-10-31

In FY13, Pacific Northwest National Laboratory (PNNL) with funding from the Department of Energy’s (DOE’s) Building Technologies Office (BTO) designed, prototyped and tested a transactional network platform to support energy, operational and financial transactions between any networked entities (equipment, organizations, buildings, grid, etc.). Initially, in FY13, the concept demonstrated transactions between packaged rooftop air conditioners and heat pump units (RTUs) and the electric grid using applications or "agents" that reside on the platform, on the equipment, on a local building controller or in the Cloud. The transactional network project is a multi-lab effort with Oakridge National Laboratory (ORNL) and Lawrence Berkeley National Laboratory (LBNL) also contributing to the effort. PNNL coordinated the project and also was responsible for the development of the transactional network (TN) platform and three different applications associated with RTUs. This document describes two applications or "agents" in details, and also summarizes the platform. The TN platform details are described in another companion document.

Balancing Energy and Performance in Dense Linear System Solvers for Hybrid ARM+GPU platforms

Directory of Open Access Journals (Sweden)

Juan P. Silva

2016-04-01

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.

1998-01-01

This paper discusses different approaches to incorporating energy technologies and technological development in energy-economic models. Technological development is a very important issue in long-term energy demand projections and in environmental analyses. Different assumptions on technological ...... of renewable energy and especially wind power will increase the rate of efficiency improvement.

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.

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

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.

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.

Microbial platform technology for recombinant antibody fragment production: A review.

Science.gov (United States)

Gupta, Sanjeev Kumar; Shukla, Pratyoosh

2017-02-01

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.

Development and application of eLearning software for education in energy technologies

Teir, S.

2002-07-01

The general aim of this project was to develop an eLearning environment for the Laboratory of Energy Engineering and Environmental Protection and implement it on their courses. This report presents the results of the research made on the concept known as eLearning, eLearning projects that had an impact on the implementation, and case studies in eLearning. After a preliminary common plan for the environment was made, the work eventually split into three separate parts: development of a course platform, course material and a process simulation interface. The section of the work regarding the course platform did not just present the research and selection of the platform. It also explained in detail what a course platform is, how it functions and how it can be used. Several different course platforms have been reviewed and the chosen one, Blackboard, is presented in detail. The presentation is not made for demonstrating Blackboard's features; it is written to show a detailed example of the features of a course platform. The course platform was implemented on most of the courses provided in autumn 2001, which provided valuable experience and feedback. The development of online course material (or eBook) for the Steam Boiler Technology course was initiated. Tools were chosen and a common layout and navigational tools were designed. The course material consists of HTML and Flash based Web pages, providing presentation, interaction and information about Steam Boiler Technology. Due to the development of the process simulation interface, which incidentally took four months to develop, only one chapter of course material was created. The course material is still under development and is expected to be ready when the course starts in autumn 2002. A Web based interface for PROSIM was developed. The interface allows the developer to use models created with PROSIM and build a graphical Web based interface around the models. These models are meant for educational use such

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

Bara, Jason E; Camper, Dean E; Gin, Douglas L; Noble, Richard D

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

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

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.

This article aims at finding the most suitable waste heat recovery technology for existing and future offshore facilities. The technologies considered in this work are the steam Rankine cycle, the air bottoming cycle and the organic Rankine cycle. A multi-objective optimization approach is employed...... to attain optimal designs for each bottoming unit by selecting specific functions tailored to the oil and gas sector, i.e. yearly CO2 emissions, weight and economic revenue. The test case is the gas turbine-based power system serving an offshore platform in the North Sea. Results indicate that the organic...... and of the primary heat exchanger, organic Rankine cycle turbogenerators appear thus to be the preferred solution to abate CO2 emissions and pollutants on oil and gas facilities. As a practical consequence, this paper provides guidelines for the design of high-efficiency, cost-competitive and low-weight power...

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.

Pottinger, C. (ed.)

2007-05-15

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.

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.

Technology Roadmap: Energy Storage

Energy Technology Data Exchange (ETDEWEB)

NONE

2014-03-01

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.

Using decommissioned offshore oil/gas platforms for nuclear/RO desalination: the ONDP (Offshore Nuclear Desalination Platform)

International Nuclear Information System (INIS)

Nagar, Ankesh

2010-01-01

Oil platforms are manmade concrete and steel giant structures standing high on ocean floor weighing anywhere between 10,000 tonnes and 150,000 tonnes or more and designed to withstand cruel forces of nature, having an average life of 70 years. With the declining petrol reserves within next 30 years, hundreds of platforms will be scheduled for decommissioning. This issue is a hot topic as oil companies tussle with environmentalists and state lawmakers over the future. The cash strapped oil companies have a legal obligation to remove each rig entirely, returning the ocean floor to its original condition. Lean times in oil industry mean a tight cash flow. Safely removing massive structures from deep waters and shipping the pile to the shores for reuse and recycling presents a technological challenge for operators. Some conceptual applications investigated to reuse them are the conversion of offshore structures into fish farms, prisons, military outposts, hotels, for Search and Rescue operations or Centers for Waste Processing and Disposal. Decommissioning oil and gas installation is exorbitantly expensive. On an average, removing a complete platform with or without pipeline in sea waters with 'clean sea approach' costs $15 million to $ 6 billion depending on location. Global warming has adversely affected world climate. Water levels in ground and reservoirs have shown drastic decrement. In future there will be need for more and more water all over the world. Fossil fuel energy based desalination is expensive and not eco-friendly so is dismantling of oil platform with its pipeline. The oil platforms are far located from population, have sufficient tank capacity and pipeline structure to store and pump water to shore. When found economically unviable these mammoth structures with modifications can be installed with 02 or more small or medium sized nuclear reactors such as KLT 40S with required module to desalinate water and co generate electricity which can be sent to

The potential of the minipig as a platform for future developments in genomics, high density biology, transgenic technology, in vitro toxicology and related emerging technologies was reviewed. Commercial interests in the pig as an agricultural production species have driven scientific progress...... pigs and humans suggest that minipigs will be useful for the testing of biotechnology products (and possibly for in silico toxicology) and (iii) the minipig is the only non-rodent toxicology model where transgenic animals can be readily generated, and reproductive technologies are well developed...... in the pig. These properties should also make the minipig an interesting model for the testing of biotechnology products. These factors all support the idea that the minipig is well placed to meet the challenges of the emerging technologies and the toxicology of the future; it also seems likely...

Energy technology evaluation report: Energy security

Science.gov (United States)

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.

Emerging energy-efficient industrial technologies

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

How Talisman Energy implemented oilfield fleet safety using event driven AVL technologies from TELUS

Energy Technology Data Exchange (ETDEWEB)

Munroe, D. [Telus Energy Sector Organization, Calgary, AB (Canada)

2006-07-01

This conference presentation provided information on how Talisman Energy implemented oilfield fleet safety using event driven automated vehicle location (AVL) technologies from TELUS. Background information on Telus in the energy sector, Telus geomatics, Telus mobile resource management (MRM) application modules, as well as Talisman Energy was first provided. Talisman looked to Telus for AVL technologies because it had a need to identify where employees were working, when they arrived and how long they were there. Prior to meeting with TELUS, Talisman Energy had implemented a system consisting of a trunk radio network to transmit data to the control room on the employee's location, however, it was unable to use the radio network to dispatch orders and communicate on an as-needed basis. TELUS had implemented a customized solution that tracks vehicles and provides an easy method of communication for employees to track how long they are working at a site. The service provides the control centre with the tools to monitor the location of the vehicles on a map, and communicate to the employee via a horn when their time has expired at the site. If the employee does not respond, the control room can call the nearest personnel to check on the worker's status. The integrated TELUS solutions uses Global Positioning System (GPS), Geographic Information Systems (GIS) and Wireless communication over the Internet. The presentation provided numerous Talisman specific maps. It concluded with several issues to consider such as cross platform cellular communications supported on a single hardware platform; additional support for Satellite communications utilizing the same GIS platform; the need for extensive support for peripheral devices; and, the need for extensive roaming capabilities. tabs., figs.

Modern communication platforms require a huge amount of switched RF component banks especially made of different filters and antennas to cover all operating frequencies and bandwidth for the targeted services and application scenarios. In contrast, reconfigurable devices made of tunable components lead to a considerable reduction in complexity, size, weight, power consumption, and cost. This paper gives an overview of suitable technologies for tunable microwave components especially for SatCom applications. Special attention is given to tunable components based on functional materials such as barium strontium titanate (BST) and liquid crystal (LC).

The platform is intended to support energy, operational and financial transactions between any networked entities (equipment, organizations, buildings, grid, etc.). Initially, in FY13, the concept demonstrated transactions between packaged rooftop units (RTUs) and the electric grid using applications or “agents” that reside on the platform, on the equipment, on local building controller or in the Cloud. This document describes the core of the transactional network platform, the Volttron Lite™ software and associated services hosted on the platform. Future enhancements are also discussed. The appendix of the document provides examples of how to use the various services hosted on the platform.

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

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.

The research of a gyro-stabilized platform and POS application technology in airborne remote sensing

Science.gov (United States)

Xu, Jiang; Du, Qi

2009-07-01

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.

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)

An ESL Approach for Energy Consumption Analysis of Cache Memories in SoC Platforms

Directory of Open Access Journals (Sweden)

Abel G. Silva-Filho

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.

Energy Policy is Technology Politics The Hydrogen Energy Case

International Nuclear Information System (INIS)

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)

Full Text Available The aim of the paper is to conduct a research on an impact of blockchain technology platform on the financial sector through cryptocurrency, and an impact on other industries.. The subject of research is not only this technology but also its commercial exploitation. In order to understand the platform, the starting point of this research is an analysis of how the technology functions, after that the advantages for business and economic transaction are identified, and finally the paper deals with an impact of new technology on business, above all on financial operations. The basic hypothesis is that blockchain has achieved a great impact on financial sector, also it has the potential to radically change only the financial sector but also the way we buy and sell, our interaction with the authorities as a way of verifying the ownership from the authorship and the organic food production. Using the available data and synthesis of knowledge from the fields of technology, economics, finance, and politics, 4 scenarios were set up for the future of underlying technology. The scenario approach combined with trend analysis in order to prove the starting hypothesis with high reliability. The research results show that the technology being investigated already has a profound impact on the financial sector, that it is in the initial phase of changing many industries, with the likelihood that they will change them significantly in the next five to ten years. Businesses increasingly discover the power of this technology to exploit the benefits of the Fourth Technological Revolution.

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 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)

Issues in offshore platform research - Part 1: Semi-submersibles

Availability of economic and efficient energy resources is crucial to a nation's development. Because of their low cost and advancement in drilling and exploration technologies, oil and gas based energy systems are the most widely used energy source throughout the world. The inexpensive oil and gas based energy systems are used for everything, i.e., from transportation of goods and people to the harvesting of crops for food. As the energy demand continues to rise, there is strong need for inexpensive energy solutions. An offshore platform is a large structure that is used to house workers and machinery needed to drill wells in the ocean bed, extract oil and/or natural gas, process the produced fluids, and ship or pipe them to shore. Depending on the circumstances, the offshore platform can be fixed (to the ocean floor) or can consist of an artificial island or can float. Semi-submersibles are used for various purposes in offshore and marine engineering, e.g. crane vessels, drilling vessels, tourist vessels, production platforms and accommodation facilities, etc. The challenges of deepwater drilling have further motivated the researchers to design optimum choices for semi-submersibles for a chosen operating depth. In our series of eight papers, we discuss the design and production aspects of all the types of offshore platforms. In the present part I, we present an introduction and critical analysis of semi-submersibles.

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%.

Inter-technology knowledge spillovers for energy technologies

International Nuclear Information System (INIS)

Nemet, Gregory F.

2012-01-01

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.

Integrating Microbial Electrochemical Technology with Forward Osmosis and Membrane Bioreactors: Low-Energy Wastewater Treatment, Energy Recovery and Water Reuse

KAUST Repository

Werner, Craig M.

2014-06-01

Wastewater treatment is energy intensive, with modern wastewater treatment processes consuming 0.6 kWh/m3 of water treated, half of which is required for aeration. Considering that wastewater contains approximately 2 kWh/m3 of energy and represents a reliable alternative water resource, capturing part of this energy and reclaiming the water would offset or even eliminate energy requirements for wastewater treatment and provide a means to augment traditional water supplies. Microbial electrochemical technology is a novel technology platform that uses bacteria capable of producing an electric current outside of the cell to recover energy from wastewater. These bacteria do not require oxygen to respire but instead use an insoluble electrode as their terminal electron acceptor. Two types of microbial electrochemical technologies were investigated in this dissertation: 1) a microbial fuel cell that produces electricity; and 2) a microbial electrolysis cell that produces hydrogen with the addition of external power. On their own, microbial electrochemical technologies do not achieve sufficiently high treatment levels. Innovative approaches that integrate microbial electrochemical technologies with emerging and established membrane-based treatment processes may improve the overall extent of wastewater treatment and reclaim treated water. Forward osmosis is an emerging low-energy membrane-based technology for seawater desalination. In forward osmosis water is transported across a semipermeable membrane driven by an osmotic gradient. The microbial osmotic fuel cell described in this dissertation integrates a microbial fuel cell with forward osmosis to achieve wastewater treatment, energy recovery and partial desalination. This system required no aeration and generated more power than conventional microbial fuel cells using ion exchange membranes by minimizing electrochemical losses. Membrane bioreactors incorporate semipermeable membranes within a biological wastewater

2011-01-01

The book 'Learning Curves: Theory, Models, and Applications' first draws a learning map that shows where learning is involved within organizations, then examines how it can be sustained, perfected, and accelerated. The book reviews empirical findings in the literature in terms of different sources for learning and partial assessments of the steps that make up the actual learning process inside the learning curve. Chapter 23 on 'Developments in Interpreting Learning Curves and Applications to Energy Technology Policy' is written by Bob van der Zwaan and Clas-Otto Wene. In this chapter they provide some interpretations of experience and learning curves starting from three different theoretical platforms. These interpretations are aimed at explaining learning rates for different energy technologies. The ultimate purpose is to find the role that experience and learning curves can legitimately play in designing efficient government deployment programs and in analyzing the implications of different energy scenarios. The 'Component Learning' section summarizes recent work by the authors that focuses on the disaggregation of technologies in their respective components and argues that traditional learning for overall technology should perhaps be replaced by a phenomenology that recognizes learning for individual components. The 'Learning and Time' section presents an approach that departs more strongly from the conventional learning curve methodology, by suggesting that exponential growth and progress may be the deeper underlying processes behind observed learning-by-doing. Contrary to this view, the cybernetic approach presented in the 'Cybernetic Approach' section sees learning curves as expressing a fundamental property of organizations in competitive markets and applies the findings from second order cybernetics to calculate the learning rates for operationally closed systems. All three interpretations find empirical support. The 'Conclusions' section summarizes the

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.

effort in term of grid technology development. 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.

Full Text Available A novel tuned heave plate energy-harvesting system (THPEH is presented for the motion suppressing and energy harvesting of a semi-submersible platform. This THPEH system is designed based on the principle of a tuned mass damper (TMD and is composed of spring supports, a power take-off system (PTO and four movable heave plates. The permanent magnet linear generators (PMLG are used as the PTO system in this design. A semi-submersible platform operating in the South China Sea is selected as the research subject for investigating the effects of the THPEH system on motion reduction and harvesting energy through numerical simulations. The numerical model of the platform and the THPEH system, which was established based on hydrodynamic analysis, is modified and validated by the results of the flume test of a 1:70 scale model. The effects of the parameters, including the size, the frequency ratio and the damping ratio of the THPEH system, are systematically investigated. The results show that this THPEH system, with proper parameters, could significantly reduce the motions of the semi-submersible platform and generate considerable power under different wave conditions.

Soft Energy Paths Revisited: Politics and Practice in Energy Technology Transitions

Directory of Open Access Journals (Sweden)

Chelsea Schelly

2016-10-01

Full Text Available This paper argues that current efforts to study and advocate for a change in energy technologies to reduce their climate and other environmental impacts often ignore the political, social, and bodily implications of energy technology choices. Framing renewable energy technologies exclusively in terms of their environmental benefits dismisses important questions about how energy infrastructures can be designed to correspond to democratic forms of socio-politics, forms of social organization that involve independence in terms of meeting energy needs, resilience in terms of adapting to change, participatory decision making and control, equitable distribution of knowledge and efficacy, and just distribution of ownership. Recognizing technological choices as political choices brings explicit attention to the kinds of socio-political restructuring that could be precipitated through a renewable energy technology transition. This paper argues that research on energy transitions should consider the political implications of technological choices, not just the environmental consequences. Further, emerging scholarship on energy practices suggests that social habits of energy usage are themselves political, in that they correspond to and reinforce particular arrangements of power. Acknowledging the embedded politics of technology, as the decades’ old concept of soft path technologies encourages, and integrating insights on the politics of technology with insights on technological practices, can improve future research on energy policy and public perceptions of energy systems. This paper extends insights regarding the socio-political implications of energy paths to consider how understandings of energy technologies as constellations of embedded bodily practices can help further develop our understanding of the consequences of energy technologies, consequences that move beyond environmental implications to the very habits and behaviors of patterned energy

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.

Full Text Available Availability of economic and efficient energy resources is crucial to a nation's development. Because of their low cost and advancement in drilling and exploration technologies, oil and gas based energy systems are the most widely used energy source throughout the world. The inexpensive oil and gas based energy systems are used for everything, i.e., from transportation of goods and people to the harvesting of crops for food. As the energy demand continues to rise, there is strong need for inexpensive energy solutions. An offshore platform is a large structure that is used to house workers and machinery needed to drill wells in the ocean bed, extract oil and/or natural gas, process the produced fluids, and ship or pipe them to shore. Depending on the circumstances, the offshore platform can be fixed (to the ocean floor or can consist of an artificial island or can float. Semi-submersibles are used for various purposes in offshore and marine engineering, e.g. crane vessels, drilling vessels, tourist vessels, production platforms and accommodation facilities, etc. The challenges of deepwater drilling have further motivated the researchers to design optimum choices for semi-submersibles for a chosen operating depth. In our series of eight papers, we discuss the design and production aspects of all the types of offshore platforms. In the present part I, we present an introduction and critical analysis of semi-submersibles.

2012-05-15

The present technology catalogue is published in co-operation between the Danish Energy Agency and Energinet.dk and includes technology descriptions for a number of technologies for individual heat production and energy transport. The primary objective of the technology catalogue is to establish a uniform, commonly accepted and up-to-date basis for the work with energy planning and the development of the energy sector, including future outlooks, scenario analyses and technical/economic analyses. The technology catalogue is thus a valuable tool in connection with energy planning and assessment of climate projects and for evaluating the development opportunities for the energy sector's many technologies, which can be used for the preparation of different support programmes for energy research and development. The publication of the technology catalogue should also be viewed in the light of renewed focus on strategic energy planning in municipalities etc. In that respect, the technology catalogue is considered to be an important tool for the municipalities in their planning efforts.

Park, Ki-Woong; Lee, Younho; Baek, Sung Hoon

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.

Dry tree semisubmersible platform: from 'technology accepted' to 'project ready'

Energy Technology Data Exchange (ETDEWEB)

Lu, Roger; Wang, Tao; Nygaard, Magne; Bendiksen, Rolf [Aker Solutions, Oslo (Norway)

2012-07-01

Development of new technologies for application of dry tree solutions on semi-submersible hull production platforms opens up new flexible and cost efficient solutions for oil and gas fields in deep and ultra deep water. Aker Solutions has brought the technology through the last steps to a project ready stage. Top tension risers allow for shifting the Christmas tree from seabed to topside, and enables drilling and production from the same unit. By shifting the wellhead and Christmas tree from seabed to platform deck, well maintenance is simplified, and makes the Dry Tree Semi relevant to consider for the Brazilian pre-salt reservoirs. Easy access to the wells for maintenance gives a potential for a higher recovery rate for the field. Future development of ultra deep water oil and gas fields demands solutions overcoming the limitations set by the TLP and the Spar buoy. Combining knowledge from already proven solutions, and a limited addition of new technology, these limitations are overcome with Aker Solutions' Dry Tree Semi. It is designed and proven for Gulf of Mexico environmental conditions. It is verified for conditions with a significant wave height of 14 meters, and able to withstand 100-year extreme weather and 1000-years survival conditions. A conventional semi-submersible platform, but with a deeper draft to further reduce the already low motions, makes the basis for the concept. Top tensioned risers (TTR) with vertical motion compensation stroke of up to 10 meters, makes it possible to shift the Christmas tree from seabed to platform deck. The deep draft design of the hull reduces the wave force excitation on the pontoons, reducing both the roll and pitch dynamics. The Dry Tree Semi represents several major benefits, including low sensitivity to water depth, reduced hull and topside weight, and flexibility in transportation, mooring, and decommissioning.

Worrell, Ernst; Martin, Nathan; Price, Lynn; Ruth, Michael; Elliott, Neal; Shipley, Anna; Thorn, Jennifer

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

A high current Nordic competence in energy technology and an increased need for funding and international cooperation in the field are the main messages of the report. This report summarizes results from 7 different research projects relating to policies for energy technology, funded by Nordic Energy Research for the period 2007-2008, and provides an analysis of the Nordic innovation systems in the energy sector. The Nordic countries possess a high level of competence in the field of renewable energy technologies. Of the total installed capacity comprises a large share of renewable energy, and Nordic technology companies play an important role in the international market. 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.

The National Renewable Energy Laboratory (NREL) and the U.S. Navy have worked together to demonstrate new or leading-edge commercial energy technologies whose deployment will support the U.S. Department of Defense (DOD) in meeting its energy efficiency and renewable energy goals while enhancing installation energy security. This is consistent with the 2010 Quadrennial Defense Review report1 that encourages the use of 'military installations as a test bed to demonstrate and create a market for innovative energy efficiency and renewable energy technologies coming out of the private sector and DOD and Department of Energy laboratories,' as well as the July 2010 memorandum of understanding between DOD and the U.S. Department of Energy (DOE) that documents the intent to 'maximize DOD access to DOE technical expertise and assistance through cooperation in the deployment and pilot testing of emerging energy technologies.' As part of this joint initiative, a promising waste-to-energy (WTE) technology was selected for demonstration at the Hickam Commissary aboard the Joint Base Pearl Harbor-Hickam (JBPHH), Hawaii. The WTE technology chosen is called high-energy densification waste-to-energy conversion (HEDWEC). HEDWEC technology is the result of significant U.S. Army investment in the development of WTE technology for forward operating bases.

Interactions of energy technology development and new energy exploitation with water technology development in China

International Nuclear Information System (INIS)

Liang, Sai; Zhang, Tianzhu

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.

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.

The sharp increase in energy usage according to the industry development has resulted in deficiency of energy resources and severe pollution problems. 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.

This nuclear energy roadmap has been prepared jointly by the IEA and the OECD Nuclear Energy Agency (NEA). Unlike most other low-carbon energy sources, nuclear energy is a mature technology that has been in use for more than 50 years. The latest designs for nuclear power plants build on this experience to offer enhanced safety and performance, and are ready for wider deployment over the next few years. Several countries are reactivating dormant nuclear programmes, while others are considering nuclear for the first time. China in particular is already embarking on a rapid nuclear expansion. In the longer term, there is great potential for new developments in nuclear energy technology to enhance nuclear's role in a sustainable energy future.

In this fiscal year, the advanced technologies in the fields of system and safety, materials and measurement were taken up. The second committee meeting was held in March, 1995. In this report, the contents of the lectures at the committee meeting and the symposium are compiled. The topics in the symposium were the meaning of advanced technologies, the advanced technologies and atomic energy, human factors and control and safety systems, robot technology and microtechnology, and functionally gradient materials. Lectures were given at two committee meetings on the development of atomic energy that has come to the turning point, the development of advanced technologies centering around ULSI, the present problems of structural fine ceramics and countermeasures of JFCC, the material analysis using laser plasma soft X-ray, and the fullerene research of advanced technology development in Power Reactor and Nuclear Fuel Development Corporation.

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

Energy technologies and innovation are considered to play a crucial role in climate change mitigation. Yet, the representation of technologies in energy-economy models, which are used extensively to analyze the economic, energy and environmental impacts of alternative energy and climate policies, is rather limited. This dissertation presents advanced techniques of including technological innovations in energy-economy computable general equilibrium (CGE) models. New methods are explored and applied for improving the realism of energy production and consumption in such top-down models. The dissertation addresses some of the main criticism of general equilibrium models in the field of energy and climate policy analysis: The lack of detailed sectoral and technical disaggregation, the restricted view on innovation and technological change, and the lack of extended greenhouse gas mitigation options. The dissertation reflects on the questions of (1) how to introduce innovation and technological change in a computable general equilibrium model as well as (2) what additional and policy relevant information is gained from using these methodologies. Employing a new hybrid approach of incorporating technology-specific information for electricity generation and iron and steel production in a dynamic multi-sector computable equilibrium model it can be concluded that technology-specific effects are crucial for the economic assessment of climate policy, in particular the effects relating to process shifts and fuel input structure. Additionally, the dissertation shows that learning-by-doing in renewable energy takes place in the renewable electricity sector but is equally important in upstream sectors that produce technologies, i.e. machinery and equipment, for renewable electricity generation. The differentiation of learning effects in export sectors, such as renewable energy technologies, matters for the economic assessment of climate policies because of effects on international

The VISPA internet platform enables users to remotely run Python scripts and view resulting plots or inspect their output data. With a standard web browser as the only user requirement on the client-side, the system becomes suitable for blended learning approaches for university physics students. VISPA was used in two consecutive years each by approx. 100 third year physics students at the RWTH Aachen University for their homework assignments. For example, in one exercise students gained a deeper understanding of Einsteins mass-energy relation by analyzing experimental data of electron-positron pairs revealing J / Ψ and Z particles. Because the students were free to choose their working hours, only few users accessed the platform simultaneously. The positive feedback from students and the stability of the platform lead to further development of the concept. This year, students accessed the platform in parallel while they analyzed the data recorded by demonstrated experiments live in the lecture hall. The platform is based on experience in the development of professional analysis tools. It combines core technologies from previous projects: an object-oriented C++ library, a modular data-driven analysis flow, and visual analysis steering. We present the platform and discuss its benefits in the context of teaching based on surveys that are conducted each semester.

Energy-storage technologies and electricity generation

Hall, Peter J.; Bain, Euan J.

2008-01-01

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

Highlights: • Renewable energy-driven desalination technologies are highlighted. • Solar, geothermal, and wind energy sources were explored. • An innovative hybrid approach (combined solar–geothermal) has also been explored. • Innovative desalination technologies developed by our group are discussed. • Climate change and GHG emissions from desalination are also discussed. - Abstract: 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 m 3 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 /m 3 ). 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 /m 3 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

This paper summarizes an assessment of future energy-technology strategies for China that explored the prospects for China to continue its social and economic development while ensuring national energy-supply security and promoting environmental sustainability over the next 50 years. The MARKAL energy-system modeling tool was used to build a model of China's energy system representing all sectors of the economy and including both energy conversion and end-use technologies. Different scenarios for the evolution of the energy system from 1995 to 2050 were explored, enabling insights to be gained into different energy development choices. The analysis indicates a business-as-usual strategy that relies on coal combustion technologies would not be able to meet all environmental and energy security goals. However, an advanced technology strategy emphasizing (1) coal gasification technologies co-producing electricity and clean liquid and gaseous energy carriers (polygeneration), with below-ground storage of some captured CO 2 ; (2) expanded use of renewable energy sources (especially wind and modern biomass); and (3) end-use efficiency would enable China to continue social and economic development through at least the next 50 years while ensuring security of energy supply and improved local and global environmental quality. Surprisingly, even when significant limitations on carbon emissions were stipulated, the model calculated that an advanced energy technology strategy using our technology-cost assumptions would not incur a higher cumulative (1995-2050) total discounted energy system cost than the business-as-usual strategy. To realize such an advanced technology strategy, China will need policies and programs that encourage the development, demonstration and commercialization of advanced clean energy conversion technologies and that support aggressive end-use energy efficiency improvements

The residential/commercial market sector, particularly as it relates to energy technologies, is described. Buildings account for about 25% of the total energy consumed in the US. Market response to energy technologies is influenced by several considerations. Some considerations discussed are: industry characteristics; market sectors; energy-consumption characeristics; industry forecasts; and market influences. Market acceptance may be slow or nonexistent, the technology may have little impact on energy consumption, and redesign or modification may be necessary to overcome belatedly perceived market barriers. 7 figures, 20 tables.

A Technology Platform to Test the Efficacy of Purification of Alginate

Directory of Open Access Journals (Sweden)

Genaro A. Paredes-Juarez

2014-03-01

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

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.

The important role of international cooperation in the field of energy technologies as a key factor in the development and global deployment of energy technologies in the industry. The most effective technology in the world of multilateral cooperation under the auspices of the International Energy Agency (IEA and other international organizations. It allows the joint efforts of the countries concerned to develop new technologies, test them and implement in production. For Russia, it is very important, because at the moment our country is not only a leading exporter of energy resources, but also has a significant impact on global energy security. At the same time Russia's FEC requires urgent and serious modernization through the development and introduction of innovative technologies on the basis of the study of international experience. Therefore the question of modernization of Russian fuel and energy complex has an international character. One way to accelerate the process of modernization of the organization is a public-private partnership that will largely depend on the nature and possibilities of Russian energy diplomacy, given the geopolitical and economic realities in connection with the sanctions imposed by Western countries against our country.

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.

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.

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.

Low consumption single-use microvalve for microfluidic PCB-based platforms

Flores, G; Aracil, C; Perdigones, F; Quero, J M

2014-01-01

In this paper, a single-use and unidirectional microvalve with low consumption of energy for PCB-based microfluidic platforms is reported. Its activation is easy because it works as a fuse. The fabrication process of the device is based on PCB technology and a typical SU-8 process, using the PCB as a substrate and SU-8 for the microfluidic channels and chambers. The microvalve is intended to be used to impulse small volumes of fluids and it has been designed to be highly integrable in PCB-based microfluidic platforms. The proposed device has been fabricated, integrated and tested in a general purpose microfluidic circuit, resulting in a low activation time, of about 100 μs, and a low consumption of energy, with a maximum of 27 mJ. These results show a significant improvement because the energy consumption is about 84% lower and the time response is about four orders of magnitude shorter if compared with similar microvalves for impulsion of fluids on PCB-based platforms.

Feeding the growing population in the U.S. will require additional land for crop and livestock production. Similarly, a growing population will require additional sources of energy. Renewable energy is likely to play an increased role in meeting the new demands of electricity consumers. Renewable energy technologies can differ from conventional technologies in their operation and their siting locations. Many renewable energy technologies have a lower energy density than conventional technologies and can also have large land use requirements. Much of the prime area suitable for renewable energy development in the U.S. has historically been used for agricultural production, and there is some concern that renewable energy installations could displace land currently producing food crops. In addition to requiring vast expanses of land, both agriculture and renewable energy can require water. The agriculture and energy sectors are responsible for the majority of water withdrawals in the U.S. Increases in both agricultural and energy demand can lead to increases in water demands, depending on crop management and energy technologies employed. Water is utilized in the energy industry primarily for power plant cooling, but it is also required for steam cycle processes and cleaning. Recent characterizations of water use by different energy and cooling system technologies demonstrate the choice of fuel and cooling system technologies can greatly impact the withdrawals and the consumptive use of water in the energy industry. While some renewable and conventional technology configurations can utilize more water per unit of land than irrigation-grown crops, other renewable technology configurations utilize no water during operations and could lead to reduced stress on water resources. Additionally, co-locating agriculture and renewable energy production is also possible with many renewable technologies, avoiding many concerns about reductions in domestic food production. Various

TECHNOLOGICAL PLATFORMS IN RUSSIAN NANOINDUSTRY: PROPLEMS AND PROSPECTS OF DEVELOPMENT

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.

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.

Application and Removal of Strippable Coatings via Remote Platform - 13133

Florida International University's (FIU's) Applied Research Center is currently supporting the Department of Energy (DOE) Environmental Management Office of D and D and Facility Engineering program. FIU is supporting DOE's initiative to improve safety, reduce technical risks, and limit uncertainty within D and D operations by identifying technologies suitable to meet specific facility D and D requirements, assessing the readiness of those technologies for field deployment, and conducting feasibility studies and technology demonstrations of selected technologies and working with technology vendors to optimize the design of their current technologies to accomplish dangerous and demanding tasks during D and D operations. To meet one identified technology gap challenge for a technology to remotely apply strippable coatings, fixatives and decontamination gels, FIU identified and performed an initial demonstration of an innovative remote fixative sprayer platform from International Climbing Machines (ICM). The selected technology was demonstrated spraying fixative products at the hot cell mockup facility at the Applied Research Center at FIU in November 2008 under cold (non-radioactive) conditions. The remotely controlled platform was remotely operated and entered the facility and sprayed a fixative onto horizontal and vertical surfaces. Based on the initial FIU demonstration and the specific technical requirements identified at the DOE facilities, a follow-up demonstration was expanded to include strippable coatings and a decontamination gel, which was demonstrated in June 2010 at the ICM facility in Ithaca, NY. This second technology evaluation documented the ability of the remote system to spray the selected products on vertical stainless steel and concrete surfaces to a height of 3 meters (10 feet) and to achieve sufficient coverage and product thickness to promote the ability to peel/remove the strippable coatings and decontamination gel. The next challenge was to

Energy technology and American democratic values

Energy Technology Data Exchange (ETDEWEB)

Thompson, G.M.

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.

Condap, R. J.

1980-03-01

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.

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.

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.

The main objectives of this thesis are: to investigate technological change and cost reduction for a number of renewable electricity technologies by means of the experience curve approach; to address related methodological issues in the experience curve approach, and, based on these insights; and to analyze the implications for achieving the Dutch renewable electricity targets for the year 2020 within a European context. In order to meet these objectives, a number of research questions have been formulated: What are the most promising renewable electricity technologies for the Netherlands until 2020 under different technological, economic and environmental conditions?; To what extent is the current use of the experience curve approach to investigate renewable energy technology development sound, what are differences in the utilization of this approach and what are possible pitfalls?; How can the experience curve approach be used to describe the potential development of partially new energy technologies, such as offshore wind energy? Is it possible to describe biomass fuel supply chains with experience curves? What are the possibilities and limits of the experience curve approach when describing non-modular technologies such as large (biomass) energy plants?; What are the main learning mechanisms behind the cost reduction of the investigated technologies?; and How can differences in the technological progress of renewable electricity options influence the market diffusion of renewable electricity technologies, and what implications can varying technological development and policy have on the implementation of renewable electricity technologies in the Netherlands? The development of different renewable energy technologies is investigated by means of some case studies. The possible effects of varying technological development in combination with different policy backgrounds are illustrated for the Netherlands. The thesis focuses mainly on the development of investment

To construct a knowledge platform of acupuncture ancient books based on data mining technology, and to provide retrieval service for users. The Oracle 10 g database was applied and JAVA was selected as development language; based on the standard library and ancient books database established by manual entry, a variety of data mining technologies, including word segmentation, speech tagging, dependency analysis, rule extraction, similarity calculation, ambiguity analysis, supervised classification technology were applied to achieve text automatic extraction of ancient books; in the last, through association mining and decision analysis, the comprehensive and intelligent analysis of disease and symptom, meridians, acupoints, rules of acupuncture and moxibustion in acupuncture ancient books were realized, and retrieval service was provided for users through structure of browser/server (B/S). The platform realized full-text retrieval, word frequency analysis and association analysis; when diseases or acupoints were searched, the frequencies of meridian, acupoints (diseases) and techniques were presented from high to low, meanwhile the support degree and confidence coefficient between disease and acupoints (special acupoint), acupoints and acupoints in prescription, disease or acupoints and technique were presented. The experience platform of acupuncture ancient books based on data mining technology could be used as a reference for selection of disease, meridian and acupoint in clinical treatment and education of acupuncture and moxibustion.

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.

This is aimed at studying the relation between the technology development of hydrogen energy and the society. In Chapter 1, a meaning of technology assessment was examined. When applying it to the hydrogen energy technology, the paper presented what content it has. In Chapter 2, the needs for hydrogen energy in society were made clear in comparison with the energy supply/demand structure in Japan and characteristics of hydrogen energy. In Chapter 3, the paper showed what kinds of technology are being developed to meet the needs in this society and arranged viewpoints for evaluating the effectiveness of the technology. In Chapter 4, the paper studied the positioning of hydrogen energy technology in the future society, and presented as examples more than one hydrogen energy/system plans which become the base to describe the impact of the technology on the society. If taking technology assessment as a part of the communication activities between the technology development and the society as did in this study, these system plans are something like the ring for people in each field to talk with. In Chapter 5, the study made from each aspect was arranged. (NEDO)

Cooperative technology development: An approach to advancing energy technology

Stern, T.

1989-09-01

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)

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

In the National Platform Electromobility, representatives from industry, science, politics, unions and societies in Germany agreed on a systematic, market-oriented and technology-open approach to become the main supplier and main market for electromobility up to the year 2020. A central component of the targeted German mean market for electromobility is an intelligent energy system: integration of electricity from renewable energy sources, demand-oriented development of a public charging infrastructure, development of an innovative charging structure. The common goal of the National Electromobility Platform is to build a self-supporting market for electric vehicles. The National Electromobility Platform will support the implementation of these intentions and measures. The underlying assumptions are reviewed annually. Derived recommendations are adapted, if necessary. Thus the National Electromobility Platform develops an annual progress report. With the end of the market scheduling phase by 2014, especially the market acceleration, demand for public infrastructure, costs and funding approaches for market acceleration as well as research and development will be re-evaluated.

The objective of the US Department of Energy Office of Environmental Management's (DOE-EM's) D and D Toolbox Project is to use an integrated systems approach to develop a suite of decontamination and decommissioning (D and D) technologies, a D and D toolbox, that can be readily used across the DOE complex to improve safety, reduce technical risks, and limit uncertainty within D and D operations. Florida International University's Applied Research Center (FIU-ARC) is supporting this initiative by identifying technologies suitable to meet specific facility D and D requirements, assessing the readiness of those technologies for field deployment, and conducting technology demonstrations of selected technologies at FIU-ARC facilities in Miami, Florida. To meet the technology gap challenge for a technology to remotely apply strippable/fixative coatings, FIU-ARC identified and demonstrated of a remote fixative sprayer platform. During this process, FIU-ARC worked closely with the Oak Ridge National Laboratory in the selection of typical fixatives and in the design of a hot cell mockup facility for demonstrations at FIUARC. For this demonstration and for future demonstrations, FIU-ARC built a hot cell mockup facility at the FIU-ARC Technology Demonstration/Evaluation site in Miami, Florida. FIU-ARC selected the International Climbing Machines' (ICM's) Robotic Climber to perform this technology demonstration. The selected technology was demonstrated at the hot cell mockup facility at FIU-ARC during the week of November 10, 2008. Fixative products typically used inside hot cells were investigated and selected for this remote application. The fixatives tested included Sherwin Williams' Promar 200 and DTM paints and Bartlett's Polymeric Barrier System (PBS). The technology evaluation documented the ability of the remote system to spray fixative products on horizontal and vertical concrete surfaces. The technology performance, cost, and health and safety issues were evaluated

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.

Electric energy storage - Overview of technologies

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.

To enhance still more effectively the research and development of energy-related/environmental technologies, research and development strategies have to be worked out from a long-term view point and policy resources such as investment in research and development should be optimally distributed after clarifying and defining the course to follow toward the achievement of research and development goals. This project aims to conduct studies, and to show the course to follow in the future, towards the establishment of a long-term energy technological strategy by investigating energy systems for around 2050, interim energy systems at the intermediate stage, and innovative energy technologies for realizing such energy systems. In Chapter 1, the position of the survey and its purpose and prerequisites are shown. In Chapter 2, the history of social and economic conditions surrounding energy/environmental technologies and of energy situation up to the present time is compiled, and the outlook is analyzed and predicted. In Chapter 3, formulation of a long-term energy technological strategy is discussed. In Chapter 5, how to embody such a strategy is shown. (NEDO)

Enabling technologies for industrial energy demand management

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

In the late 1980s Finland`s Ministry of Trade and Industry (KTM) initiated a series of research and development (R and D) programmes in the field of energy technology. Subsequently, in 1993, it launched a further suite of eleven Energy Technology Programmes scheduled to run over the period 1993-1998. Aimed at the development of efficient and environmentally sound energy technologies intended to be competitive in the international marketplace, the programmes sought to involve the research, industrial and public sectors in some FIM 1.2 billion of research and development activity. The technology areas spanned: Combustion and gasification techniques Bioenergy, Advanced energy systems and technologies (e.g. wind, solar energy), Fusion, Energy and environmental technology, Energy and the environment in transportation, Energy use in buildings, Energy in steel and metal production, Energy in paper and board production, District heating, Electricity distribution automation. In early 1995, the Technology Development Centre of Finland (Tekes) assumed responsibility for the funding, management and administration of the programmes. As the final year of activities began, Tekes commissioned Technopolis to assemble a team to conduct a major review of all eleven programmes over the course of 1998. The broad aim of the exercise was to review the experience of the eleven technology R and D programmes and to make suggestions for the future. In particular, the intention was to cover a number of distinct levels. Most important were the Programme and Portfolio levels. At the individual Programme level, the review was to comment on the relevance, calibre and impact of programmes, concentrating in particular on the following: Relevance - were programme and project level goals in line with Finnish interests and comparable agendas in other countries; Efficiency - how well were the programmes implemented and managed; Quality - how did the scientific and technological quality of the work

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.

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.

Sustainable electric energy supply by decentralized alternative energy technologies

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

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.

It is exemplified by Norway. Spillover is obtained from the technology-rich global Energy Technology Perspective model operated by the International Energy Agency. It is provided to a national hybrid model where a national bottom-up Markal model carries forward spillover into a national top-down CGE model at a disaggregated demand category level. Spillover of technology learning from the global energy technology market will reduce national generation costs of energy carriers. This may in turn increase demand in the non-energy sectors of the economy because of the rebound effect. The influence of spillover on the Norwegian economy is most pronounced for the production level of industrial chemicals and for the demand for electricity for residential energy services. The influence is modest, however, because all existing electricity generating capacity is hydroelectric and thus compatible with the low emission policy scenario. In countries where most of the existing generating capacity must be replaced by nascent energy technologies or carbon captured and storage the influence on demand is expected to be more significant. - Highlights: → Spillover of global technology learning may be forwarded into a macroeconomic model. → The national electricity price differs significantly between the different global scenarios. → Soft-linking global and national models facilitate transparency in the technology learning effect chain.

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

Stimulating R and D of industrial energy-efficient technology. Policy lessons--impulse technology

International Nuclear Information System (INIS)

Luiten, Esther; Blok, Kornelis

2004-01-01

Stimulating research and development (R and D) of innovative energy-efficient technologies for industry is an attractive option for reducing greenhouse gas emissions. Impulse technology, an innovative papermaking technology, is always included in studies assessing the long-term potential of industrial energy efficiency. Aim of this article is to analyse the R and D trajectory of impulse technology in order to explore how government can stimulate the development of industrial energy-efficient technology. The concept of 'momentum' is used to characterise the network of actors and to understand the effect of government R and D support in this particular case study. The network analysis convincingly shows that although marketed as an energy-efficient technology, other benefits were in fact driving forces. Researchers at various national pulp and paper research institutes were successful in attracting government R and D support by claiming an improved energy efficiency. The momentum of the technology network was modest between 1980 and 1990. Therefore, government R and D support accelerated the development of impulse technology in this period. However, when the perspectives of the technology deteriorated--momentum decreased--researchers at national research institutes continued to attract government R and D support successfully. But 25 years of R and D--and over 15 years government R and D support--have not yet resulted in a proven technology. The case study illustrates the risk of continuing R and D support too long without taking into account actors' drivers to invest in R and D. Once momentum decreased, government should have been more circumspect in evaluating the (energy efficiency) promise of impulse technology. The major policy lesson is that government has to look beyond claimed energy efficiencies; government has to value (qualitative) information on (changing) technology networks in deciding upon starting, continuing or pulling out financial R and D support to

Full Text Available The article aims at clarifying Russian industrial policy as a result of business models changing and market reconstruction. The research bass on the hypothesis that the choice of the industrial policy administrative measures depends on the object of management. It is important to link government regulation of markets with corporate strategies. We reveal that modern economic systems based on using of electronic technologies, big data, and innovative activity. Technological platforms as the single organizational and economic mechanisms affect economic systems very much. We study the content and main characteristics of a business model, is called the "technological platform". We also identify the main required changes in industrial policy. We analyze the matching between scientific and technological scenarios of the Russian economic development and the technological platform. There are two areas of the new industrial policy. They are: a multi-sectoral approach to regulating and improving the quality of the national institutional environment. The industrial and cluster management approaches are inefficient in modern conditions. There is a need for each platform of its technological development scenario. We also clarify the role of the state in the functioning of technological platforms.

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.

In the 21st century global environment and energy issues become very important, and this is characterized by the long-term (in the scale of a few tens years) and world-wide issue. In addition, future prospect of these issues might be quite uncertain, and scientific prediction could be very difficult. For these issues vigorous researches and various efforts have been carried out from various aspects; e.g., world-wide discussion such as COP3 in Kyoto, promotion of the energy-saving technology and so on. Development of environment-friendly energy has been promoted, and new innovative technologies are explored. Nuclear fusion is, of course, a promising candidate. While, there might be some criticism for nuclear fusion from the socio-economic aspect; e.g., it would take long time and huge cost for the fusion reactor development. In addition, other innovative energy technologies might have their own criticism, as well. Therefore, socio-economic research might be indispensable for future energy resources. At first we have selected six items as for the characteristics, which might be important for future energy resources; i.e., energy resource, environmental load, economics, reliability/stability, flexibility on operation and safety/security. Concerning to innovative energy technologies, we have nominated seven candidates; i.e., advanced coal technology with CO2 recovery system, SOFC top combined cycle, solar power, wind power, space solar power station, advanced fission and fusion. Based on questionnaires for ordinary people and fusion scientists, we have tried to assess the fusion energy development, comparing with other innovative energy technologies. (author)

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.)

2005-12-15

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)

Florida International University's (FIU's) Applied Research Center is currently supporting the Department of Energy (DOE) Environmental Management Office of D and D and Facility Engineering program. FIU is supporting DOE's initiative to improve safety, reduce technical risks, and limit uncertainty within D and D operations by identifying technologies suitable to meet specific facility D and D requirements, assessing the readiness of those technologies for field deployment, and conducting feasibility studies and technology demonstrations of selected technologies and working with technology vendors to optimize the design of their current technologies to accomplish dangerous and demanding tasks during D and D operations. To meet one identified technology gap challenge for a technology to remotely apply strippable coatings, fixatives and decontamination gels, FIU identified and performed an initial demonstration of an innovative remote fixative sprayer platform from International Climbing Machines (ICM). The selected technology was demonstrated spraying fixative products at the hot cell mockup facility at the Applied Research Center at FIU in November 2008 under cold (non-radioactive) conditions. The remotely controlled platform was remotely operated and entered the facility and sprayed a fixative onto horizontal and vertical surfaces. Based on the initial FIU demonstration and the specific technical requirements identified at the DOE facilities, a follow-up demonstration was expanded to include strippable coatings and a decontamination gel, which was demonstrated in June 2010 at the ICM facility in Ithaca, NY. This second technology evaluation documented the ability of the remote system to spray the selected products on vertical stainless steel and concrete surfaces to a height of 3 meters (10 feet) and to achieve sufficient coverage and product thickness to promote the ability to peel/remove the strippable coatings and decontamination gel.

This research assesses the impact of development of practical hydrogen energy technology on the economy, society and environment in Japan, and proposes some effective countermeasures, the required technical development target and a promising promotion system. The example of technology assessment assuming practical technology several tens years after is hardly found. Hydrogen energy technology is in the first stage among (1) initial planning stage, (2) technical research and development stage, (3) practical technology stage and (4) service operation stage. In the first fiscal year, as the first stage of determination of the communication route between society and technology, study was made on the concrete system image of practical technology. In this fiscal year, study was made entirely on preparation of the scenario for imaging the future economy and society concretely, modifying the planning of the hydrogen energy system. Through comparison of the scenario and system, the meaning and problem of the hydrogen energy technology were clarified. (NEDO)

Wearable Device Control Platform Technology for Network Application Development

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, 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.

Concerns arising due to the variability and intermittency of renewable energy sources while integrating with the power grid can be mitigated to an extent by incorporating a storage element within the renewable energy harnessing system. Thus, battery energy storage systems (BESS) are likely to have a significant impact in the small-scale integration of renewable energy sources into commercial building and residential dwelling. These storage technologies not only enable improvements in consumption levels from renewable energy sources but also provide a range of technical and monetary benefits. This paper provides a modelling framework to be able to quantify the associated benefits of renewable resource integration followed by an overview of various small-scale energy storage technologies. A simple, practical and comprehensive assessment of battery energy storage technologies for small-scale renewable applications based on their technical merit and economic feasibility is presented. Software such as Simulink and HOMER provides the platforms for technical and economic assessments of the battery technologies respectively. (author)

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.

Atmospheric confetti. Inchworm crawlers. Blankets of ground penetrating radar. These are some of the unique mission concepts which could be enabled by a printable spacecraft. Printed electronics technology offers enormous potential to transform the way NASA builds spacecraft. A printed spacecraft's low mass, volume and cost offer dramatic potential impacts to many missions. Network missions could increase from a few discrete measurements to tens of thousands of platforms improving areal density and system reliability. Printed platforms could be added to any prime mission as a low-cost, minimum resource secondary payload to augment the science return. For a small fraction of the mass and cost of a traditional lander, a Europa flagship mission might carry experimental printed surface platforms. An Enceladus Explorer could carry feather-light printed platforms to release into volcanic plumes to measure composition and impact energies. The ability to print circuits directly onto a variety of surfaces, opens the possibility of multi-functional structures and membranes such as "smart" solar sails and balloons. The inherent flexibility of a printed platform allows for in-situ re-configurability for aerodynamic control or mobility. Engineering telemetry of wheel/soil interactions are possible with a conformal printed sensor tape fit around a rover wheel. Environmental time history within a sample return canister could be recorded with a printed sensor array that fits flush to the interior of the canister. Phase One of the NIAC task entitled "Printable Spacecraft" investigated the viability of printed electronics technologies for creating multi-functional spacecraft platforms. Mission concepts and architectures that could be enhanced or enabled with this technology were explored. This final report captures the results and conclusions of the Phase One study. First, the report presents the approach taken in conducting the study and a mapping of results against the proposed

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.

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

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.

New technology and possible advances in energy storage

International Nuclear Information System (INIS)

Baker, John

2008-01-01

Energy storage technologies may be electrical or thermal. Electrical energy stores have an electrical input and output to connect them to the system of which they form part, while thermal stores have a thermal input and output. The principal electrical energy storage technologies described are electrochemical systems (batteries and flow cells), kinetic energy storage (flywheels) and potential energy storage, in the form of pumped hydro and compressed air. Complementary thermal storage technologies include those based on the sensible and latent heat capacity of materials, which include bulk and smaller-capacity hot and cold water storage systems, ice storage, phase change materials and specific bespoke thermal storage media. For the majority of the storage technologies considered here, the potential for fundamental step changes in performance is limited. For electrochemical systems, basic chemistry suggests that lithium-based technologies represent the pinnacle of cell development. This means that the greatest potential for technological advances probably lies in the incremental development of existing technologies, facilitated by advances in materials science, engineering, processing and fabrication. These considerations are applicable to both electrical and thermal storage. Such incremental developments in the core storage technologies are likely to be complemented and supported by advances in systems integration and engineering. Future energy storage technologies may be expected to offer improved energy and power densities, although, in practice, gains in reliability, longevity, cycle life expectancy and cost may be more significant than increases in energy/powerdensity per se

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

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.

Geothermal energy research and development by the Sunshine Project is subdivided into five major categories: exploration and exploitation technology, hot-water power generation technology, volcanic power generation technology, environmental conservation and multi-use technology, and equipment materials research. The programs are being carried out by various National Research Institutes, universities, and private industry. During 1976 and 1977, studies were made of the extent of resources, reservoir structure, ground water movement, and neotectonics at the Onikobe and Hachimantai geothermal fields. Studies to be performed in the near future include the use of new prospecting methods, including artificial magnetotellurics, heat balance calculation, brightspot techniques, and remote sensing, as well as laboratory studies of the physical, mechanical, and chemical properties of rock. Studies are continuing in the areas of ore formation in geothermal environments, hot-dry-rock drilling and fracturing, large scale prospecting technology, high temperature-pressure drilling muds and well cements, and arsenic removal techniques.

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

Stratospheric Platforms for Monitoring Purposes

International Nuclear Information System (INIS)

Konigorski, D.; Gratzel, U.; Obersteiner, M.; Schneidereit, M.

2010-01-01

Stratospheric platforms are emerging systems based on challenging technology. Goal is to create a platform, payload, and mission design which is able to complement satellite services on a local scale. Applications are close to traditional satellite business in telecommunication, navigation, science, and earth observation and include for example mobile telecommunications, navigation augmentation, atmospheric research, or border control. Stratospheric platforms could potentially support monitoring activities related to safeguards, e.g. by imagery of surfaces, operational conditions of nuclear facilities, and search for undeclared nuclear activities. Stratospheric platforms are intended to be flown in an altitude band between 16 and 30 km, above 16-20 km to take advantage of usually lower winds facilitating station keeping, below 30 km to limit the challenges to achieve a reasonable payload at acceptable platform sizes. Stratospheric platforms could substitute satellites which are expensive and lack upgrade capabilities for new equipment. Furthermore they have practically an unlimited time over an area of interest. It is intended to keep the platforms operational and maintenance free on a 24/7 basis with an average deployment time of 3 years. Geostationary satellites lack resolution. Potential customers like Armed Forces, National Agencies and commercial customers have indicated interest in the use of stratospheric platforms. Governmental entities are looking for cheaper alternatives to communications and surveillance satellites and stratospheric platforms could offer the following potential advantages: Lower operational cost than satellite or UAV (Unmanned Aerial Vehicles) constellation (fleet required); Faster deployment than satellite constellation; Repositioning capability and ability to loiter as required; Persistent long-term real-time services over a fairly large regional spot; Surge capability: Able to extend capability (either monitoring or communications

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

Energy technologies and the environment: Environmental information handbook

Energy Technology Data Exchange (ETDEWEB)

1988-10-01

This revision of Energy Technologies and the Environment reflects the changes in energy supply and demand, focus of environmental concern, and emphasis of energy research and development that have occurred since publication of the earlier edition in 1980. The increase in availability of oil and natural gas, at least for the near term, is responsible in part for a reduced emphasis on development of replacement fuels and technologies. Trends in energy development also have been influenced by an increased reliance on private industry initiatives, and a correspondingly reduced government involvement, in demonstrating more developed technologies. Environmental concerns related to acid rain and waste management continue to increase the demand for development of innovative energy systems. The basic criteria for including a technology in this report are that (1) the technology is a major current or potential future energy supply and (2) significant changes in employing or understanding the technology have occurred since publication of the 1980 edition. Coal is seen to be a continuing major source of energy supply, and thus chapters pertaining to the principal coal technologies have been revised from the 1980 edition (those on coal mining and preparation, conventional coal-fired power plants, fluidized-bed combustion, coal gasification, and coal liquefaction) or added as necessary to include emerging technologies (those on oil shale, combined-cycle power plants, coal-liquid mixtures, and fuel cells).

Heterogeneous policies, heterogeneous technologies: The case of renewable energy

International Nuclear Information System (INIS)

Nicolli, Francesco; Vona, Francesco

2016-01-01

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 finding is that, compared to privatisation and unbundling, reducing entry barriers is a more significant driver of renewable energy innovation, but that its effect varies across technologies and is stronger in technologies characterised by potential entry of small, independent power producers. In addition, 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, ratification of the Kyoto protocol, which determined a more stable and less uncertain policy framework, amplifies the inducement effect of both energy policy and market liberalisation. - Highlights: • We study the effect of market regulation and energy policy on renewable technologies. • Reducing entry barriers is a significant driver of renewable energy innovation. • The Kyoto protocol amplifies the effect of both energy policy and liberalisation. • These effects are heterogeneous across technologies and stronger for wind.

According to the usual meaning, technological trends are determined by main companies and leading countries with capacity for the development and marketing of technology. Presently, those trends are addressed to: the development of cleaner and more efficient process for fossil fuels utilization (atmospheric and pressurized fluidized beds, integrated gasification in combined cycle, advanced combined cycles, etc), the development of safer and more economic nuclear reactors; the efficiency increase in both generation and utilisation of energy, including demand side management and distribution automation; and the reduction of cost of renewable energies. Singular points of these trends are: the progress in communication technologies (optical fibre, trucking systems, etc.); the fuel cells; the supercritical boilers; the passive reactors; the nuclear fusion; the superconductivity; etc. Spain belongs to the developed countries but suffer of certain technology shortages that places it in a special situation.

A Survey of Communications and Networking Technologies for Energy Management in Buildings and Home Automation

Full Text Available With the exploding power consumption in private households and increasing environmental and regulatory restraints, the need to improve the overall efficiency of electrical networks has never been greater. That being said, the most efficient way to minimize the power consumption is by voluntary mitigation of home electric energy consumption, based on energy-awareness and automatic or manual reduction of standby power of idling home appliances. Deploying bi-directional smart meters and home energy management (HEM agents that provision real-time usage monitoring and remote control, will enable HEM in “smart households.” Furthermore, the traditionally inelastic demand curve has began to change, and these emerging HEM technologies enable consumers (industrial to residential to respond to the energy market behavior to reduce their consumption at peak prices, to supply reserves on a as-needed basis, and to reduce demand on the electric grid. Because the development of smart grid-related activities has resulted in an increased interest in demand response (DR and demand side management (DSM programs, this paper presents some popular DR and DSM initiatives that include planning, implementation and evaluation techniques for reducing energy consumption and peak electricity demand. The paper then focuses on reviewing and distinguishing the various state-of-the-art HEM control and networking technologies, and outlines directions for promoting the shift towards a society with low energy demand and low greenhouse gas emissions. The paper also surveys the existing software and hardware tools, platforms, and test beds for evaluating the performance of the information and communications technologies that are at the core of future smart grids. It is envisioned that this paper will inspire future research and design efforts in developing standardized and user-friendly smart energy monitoring systems that are suitable for wide scale deployment in homes.

Energy management under policy and technology uncertainty

2012-01-01

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 document is the final report of a two-year development, test, and demonstration project entitled 'Cohesive Application of Standards-Based Connected Devices to Enable Clean Energy Technologies.' The project was part of the National Renewable Energy Laboratory's (NREL) Integrated Network Test-bed for Energy Grid Research and Technology (INTEGRATE) initiative. The Electric Power Research Institute (EPRI) and a team of partners were selected by NREL to carry out a project to develop and test how smart, connected consumer devices can act to enable the use of more clean energy technologies on the electric power grid. The project team includes a set of leading companies that produce key products in relation to achieving this vision: thermostats, water heaters, pool pumps, solar inverters, electric vehicle supply equipment, and battery storage systems. A key requirement of the project was open access at the device level - a feature seen as foundational to achieving a future of widespread distributed generation and storage. The internal intelligence, standard functionality and communication interfaces utilized in this project result in the ability to integrate devices at any level, to work collectively at the level of the home/business, microgrid, community, distribution circuit or other. Collectively, the set of products serve as a platform on which a wide range of control strategies may be developed and deployed.

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.

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.

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

Preuster, Patrick; Alekseev, Alexander; Wasserscheid, Peter

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.

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

2017-09-01

The clean energy transition requires a co-evolution of innovation, investment, and deployment strategies for emerging energy storage technologies. A deeply decarbonized energy system research platform needs materials science advances in battery technology to overcome the intermittency challenges of wind and solar electricity. Simultaneously, policies designed to build market growth and innovation in battery storage may complement cost reductions across a suite of clean energy technologies. Further integration of R&D and deployment of new storage technologies paves a clear route toward cost-effective low-carbon electricity. Here we analyse deployment and innovation using a two-factor model that integrates the value of investment in materials innovation and technology deployment over time from an empirical dataset covering battery storage technology. Complementary advances in battery storage are of utmost importance to decarbonization alongside improvements in renewable electricity sources. We find and chart a viable path to dispatchable US$1 W-1 solar with US$100 kWh-1 battery storage that enables combinations of solar, wind, and storage to compete directly with fossil-based electricity options.

As a large percentage of the world's poor come from India, development in India is a key issue. After the establishment of how access to energy enhances development and the achievement of the millennium development goals, energy poverty has become a major issue. In India there is a great interest in addressing the subject of energy poverty, in order to reach development goals set by the Government. This will imply an increase in India's energy needs. In a climate of change and environmental consciousness, sustainable alternatives must be considered to address these issues. Renewable energy technologies could provide a solution to this problem. The Government of India has been focussing in implementing electricity policies as well as on promoting renewable energy technologies. The focus of this article is to bring to light the problems faced in India in terms of energy consumption as well as the hindrances faced by renewable-based electrification networks. Government policies aimed at addressing these issues, as well as the current state of renewable energy technologies in India are discussed, so as to analyse the possibility of a solution to the problems of finding a sustainable method to eradicate energy poverty in India. The research reveals that the Government of India has been unable to meet some of its unrealistic development goals, and in order to achieve the remaining goals it will have to take drastic steps. The Government will have to be more aggressive in the promotion of renewable energy technologies in order to achieve sustainable development in India. (author)

Malen, Joel; Marcus, Alfred A.

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.

New technologies will be critical in addressing current global energy challenges such as energy security. More must be done, however, to push forward the development and deployment of the technologies we need today and will need in the future. Government leaders have repeatedly underlined the crucial role of industry and businesses in advancing energy technologies and the importance of strong collaboration among all stakeholders to accelerate technology advances. To attain these goals, increased co-operation between industries, businesses and government energy technology research is indispensable. The public and private sectors must work together, share burdens and resources, while at the same time multiplying results and outcomes. The 42 multilateral technology initiatives (Implementing Agreements) supported by the IEA are a flexible and effective framework for IEA member and non-member countries, businesses, industries, international organisations and non-government organisations to research breakthrough technologies, to fill existing research gaps, to build pilot plants, to carry out deployment or demonstration programmes -- in short to encourage technology-related activities that support energy security, economic growth and environmental protection. This publication highlights the significant accomplishments of the IEA Implementing Agreements.

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.

Accelerating the adoption of new and existing cost-effective technologies has significant potential to reduce the energy consumed in US buildings. This report presents key results of an interlaboratory technology transfer planning effort in support of the US Department of Energy's Office of Building Technologies (OBT). A guiding assumption for planning was that OBT's R D program should forge linkages with existing programs whose goals involved enhancing energy efficiency in buildings. An ad hoc Technology Transfer Advisory Group reviewed the existing analysis and technology transfer program, brainstormed technology transfer approaches, interviewed DOE program managers, identified applicable research results, and developed a framework that management could use in deciding on the best investments of technology transfer resources. Representatives of 22 organizations were interviewed on their views of the potential for transferring energy efficiency technologies through active linking with OBT. The report describes these programs and interview results; outlines OBT tools, technologies, and practices to be transferred; defines OBT audiences; identifies technology transfer functions and presents a framework devised using functions and audiences; presents some 60 example technology transfer activities; and documents the Advisory Group's recommendations. 37 refs., 3 figs., 12 tabs.

High energy beam manufacturing technologies

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

We examine the effect of energy prices and technological knowledge on innovation in green energy technologies. In doing so, we consider both demand-pull effects, which induce innovative activity by increasing the expected value of innovations, and technology-push effects, which drive innovative activity by extending the technological capability of an economy. Our analysis is conducted using patent data from the European Patent Office on a panel of 26 OECD countries over the period 1978-2009. Utilizing a dynamic count data model for panel data, we analyze 11 distinct green energy technologies. Our results indicate that the existing knowledge stock is a significant driver of green energy innovation for all technologies. Furthermore, the results suggest that energy prices have a positive impact on innovation for some but not all technologies and that the e.ect of energy prices and technological knowledge on green energy innovation becomes more pronounced after the Kyoto protocol agreement in 1997.

Performance Analysis of Multiple Wave Energy Converters Placed on a Floating Platform in the Frequency Domain

2018-02-01

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.

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

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.

A Sustainable Home Energy Prosumer-Chain Methodology with Energy Tags over the Blockchain

Full Text Available In this paper, we aim to provide a power trade system that will promote a sustainable electrical energy transaction ecosystem between prosumers and consumers of smart homes. We suggest a blockchain-based peer-to-peer (P2P energy transaction platform be implemented to enable efficient electrical energy transaction between prosumers. We suggest the platform be built on the blockchain, as this technology allows a decentralized and distributed trading system, and allows a more transparent, trustworthy and secure P2P trading environment. We believe that such characteristics of the blockchain are necessary in electrical energy transactions within the smart home environment because the smart home aims to enhance user comfort and security, along with energy conservation and cost-savings. First, we classify the two different types of P2P trade to identify which will best benefit from the use of the suggested blockchain-based P2P energy-transaction platform. Within the two types of P2P trade, that we classify (pure P2P trade and hybrid P2P trade, the hybrid P2P trade will benefit more from a blockchain-based P2P energy-transaction platform. In the blockchain-based P2P energy-transaction platform, a smart contract is embedded in the blockchain and called an energy tag. The energy tag will set conditions for making every future energy transaction more cost-efficient while maintaining the most ideal and high-quality energy selection. With the blockchain-based energy tag in the energy-transaction process, multiple energy resources and home appliances will be democratically connected in order to provide users with high-quality, low-cost energy at all times and locations. In this paper, we provide simulation results that compare the unit price of electrical energy on the suggested platform to the unit price of electrical energy set by currently existing conventional power-generation companies. Additionally, we present simulation results that calculate how long

Projected cost-performance data are used to calculate the Canadian commercial potential of selected renewable energy technologies to the year 2010. Based on projected market penetration, the extent to which renewable energy can contribute to environmental initiatives is also examined. The potential for renewable energy to contribute to the Canadian electricity supply is limited neither by the state of the technology nor the extent of the resource available. Barriers to acceptance of renewables include high initial capital costs, intermittent nature of much of the energy supply, land requirements, onerous requirements for environmental assessments and licensing, and lack of government policies which consider the externalities involved in new energy supply. Environmental benefits which will drive the adoption of renewables in Canada include the sustainable nature of renewable resources, low environmental impacts, and suitability for integrated resource planning. In addition, the cost performance of renewable technologies is improving rapidly. Under base-case scenarios, at current buyback rates, only small hydro and biomass of the five renewable technologies examined has significant commercial potential in Canada. At buyback rates that reflect currently projected avoided costs plus an additional 2 cents per kWh as an environmental premium, all five renewable technologies except for photovoltaics have appreciable commercial potential achievable by 2010. The quantity of electrical energy displaced under this latter scenario is estimated at 49 TWh/y, or 7% of the projected total generation in Canada. 2 figs., 2 tabs

The scope of this project was to demonstrate tools and technologies to reduce energy use in military housing, with particular emphasis on measuring and reducing loads related to consumer electronics (commonly referred to as 'plug loads'), hot water, and whole-house cooling.

Market penetration rates of new energy technologies

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

Heterogeneous Policies, Heterogeneous Technologies: The Case of Renewable Energy

Nicolli, Francesco; Vona, Francesco

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.

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

The sodium cooled fast reactors (SFR) French program currently focused on the design of the ASTRID (Advanced Sodium Technological Reactor for Industrial Demonstration) reactor in different fields: energy conversion system, instrumentation for continuous monitoring, In Service Inspection and Repair, core design, fuel handling, thermo hydraulic, severe accidents, large flow electromagnetic pumps... Even if the French experimental prototype implies the development of innovative techniques, concepts and feedback of operations of SFRs are important, the new challenges coming from the objectives to meet GEN-IV requirements need some research and development. To achieve this goal, the generation four French SFR program includes the development of technological platforms with experimental facilities to develop and evaluate innovative options and also qualify some ASTRID specific components. The needs in terms of development, validation and qualification of techniques, components or systems to be used on ASTRID have been reviewed exhaustively in 2014. It allowed to consolidate or to precise the experimental purposes of the four CEA platforms regrouping technological facilities with different strategy of erection. PAPIRUS platform (largely already constructed) is dedicated to in-sodium experimental testing; GISEH platform (also largely already constructed) is devoted to water and air tests in support to hydraulic, thermal-hydraulic and fluid-structure interaction studies; CHEOPS platform (detailed studies and realization contract launched in 2014 aiming at commissioning and start up in 2018) deals with in sodium research and development and some qualifications requiring large scale; and last, PLINIUS-2 platform (commissioning and start up in 2019) concerns prototypic corium behavior studies in severe accident conditions and mitigation device qualification. This paper presents the four platforms and for each of them the experimental needs which are covered by their facilities

Potential for energy technologies in residential and commercial buildings

The residential-commercial energy technology model was developed as a planning tool for policy analysis in the residential and commercial building sectors. The model and its procedures represent a detailed approach to estimating the future acceptance of energy-using technologies both in new construction and for retrofit into existing buildings. The model organizes into an analytical framework all relevant information and data on building energy technology, building markets, and government policy, and it allows for easy identification of the relative importance of key assumptions. The outputs include estimates of the degree of penetration of the various building energy technologies, the levels of energy use savings associated with them, and their costs - both private and government. The model was designed to estimate the annual energy savings associated with new technologies compared with continued use of conventional technology at 1975 levels. The amount of energy used under 1975 technology conditions is referred to as the reference case energy use. For analytical purposes the technologies were consolidated into ten groupings: electric and gas heat pumps; conservation categories I, II, and III; solar thermal (hot water, heating, and cooling); photovoltaics, and wind systems. These groupings clearly do not allow an assessment of the potential for individual technologies, but they do allow a reasonable comparison of their roles in the R/C sector. Assumptions were made regarding the technical and economic performances of the technologies over the period of the analysis. In addition, the study assessed the non-financial characteristics of the technologies - aesthetics, maintenance complexity, reliability, etc. - that will also influence their market acceptability.

The Morgantown Energy Technology Center (METC), located in Morgantown, West Virginia, is an energy research center of the US Department of Energy's (DOE's) Office of Fossil Energy. The research and development work is different from research work conducted by other Government agencies. In DOE research, the Government is not the ultimate ''customer'' for the technologies developed; the ''customer'' is business and industry in the private sector. Thus, tehcnology transfer is a fundamental goal of the DOE. The mission of the Fossil Energy program is to enhance the use of the nations's fossil energy resources. METC's mission applies to certain technologies within the broad scope of technologies encompassed by the Office of Fossil Energy. The Government functions as an underwriter of risk and as a catalyst to stimulate the development of technologies and technical information that might otherwise proceed at a slower pace because of the high-risk nature of the research involved. The research programs and priorities are industry driven; the purpose is to address the perceived needs of industry such that industry will ultimately bring the technologies to the commercial market. As evidenced in this report, METC has an active and effective technology transfer program that is incorporated into all aspects of project planning and execution. Technology transfer at METC is a way of life---a part of everyday activities to further this goal. Each person has a charge to communicate the ideas from within METC to those best able to utilize that information. 4 figs., 20 tabs.

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)

Silicon photonics technology, which has the DNA of silicon electronics technology, promises to provide a compact photonic integration platform with high integration density, mass-producibility, and excellent cost performance. This technology has been used to develop and to integrate various photonic functions on silicon substrate. Moreover, photonics-electronics convergence based on silicon substrate is now being pursued. Thanks to these features, silicon photonics will have the potential to be a superior technology used in the construction of energy-efficient cost-effective apparatuses for various applications, such as communications, information processing, and sensing. Considering the material characteristics of silicon and difficulties in microfabrication technology, however, silicon by itself is not necessarily an ideal material. For example, silicon is not suitable for light emitting devices because it is an indirect transition material. The resolution and dynamic range of silicon-based interference de...
