Solar heating cooling. Preparation of possible participation in IEA, Solar Heating Cooling Task 25

International Nuclear Information System (INIS)

2001-03-01

For the Danish solar heating industries it is interesting to discuss the domestic market possibilities and the export possibilities for solar heating cooling systems. The Danish solar heating sector also wants to participate in the international collaboration within IEA Solar Heating and Cooling Task 25 'Solar Assisted Air Conditioning of Buildings'. The Danish Energy Agency therefore has granted means for this project to discuss: The price of cooling for 3 different solar cooling methods (absorption cooling, desiccant cooling and ejector cooling); Market possibilities in Denmark and abroad; The advantages by Danish participation in IEA Task 25. The task has been solved through literature studies to establish status for the 3 technologies. It turned out that ejector cooling by low temperatures (85 deg. C from the solar collector) exists as pilot plants in relation to district heating, but is still not commercial accessible. Desiccant cooling, where the supplied heat has temperatures down to 55 deg. C is a well-developed technology. However only a handful of pilot plants with solar heating exists, and thus optimization relating to operation strategy and economy is on the experimental stage. Absorption cooling plants driven by solar heating are found in a large number in Japan and are also demonstrated in several other countries. The combination of absorption heating pump and solar heating is considered to be commercial accessible. Solar heating is interesting as heat source of to the extent that it can replace other sources of heat without the economy being depreciated. This can be the case in South Europe if: 1) oil or natural gas is used for heating; 2) a solar heating system already exists, e.g. for domestic water supply, and is installed so that the marginal costs by solar heating supply of the ventilation plant is reduced. All in all the above conditions mean that the market for solar heating for cooling is very limited in Europe, where almost everybody are

1994-04-01

The IEA workshop on Daylight in Buildings was held in Copenhagen on March 14-16, 1994. At the workshop, presentations were given on key topics as a basis for discussions by the experts participating in the meeting. The presentations and discussions covered a range of technical, architectural and amenity aspects of daylighting in buildings. A great interest in research collaboration on daylight was expressed, and it was agreed that plenty of work still needs to be done, and that the appropriate form of work would be an IEA Task. It was agreed that daylighting systems and control strategies should be evaluated and tested in test rooms, as well as in existing buildings as case studies. Furthermore, the workshop expressed that one of the best ways to realize and present the Task results to practice would be through a few demonstration buildings, build in different countries and under different climatic conditions.

This report describes the work performed within the first phase of IEA Task 29 Mexnext. In this IEA Task 29 a total of 20 organisations from 11 different countries collaborated in analysing the measurements which have been performed in the EU project 'Mexico'. Within this Mexico project 9 European institutes carried out a wind tunnel experiment in the Large Low Speed Facility (LLF) of the German Dutch Wind Facilities DNW on a rotor with a diameter of 4.5 m. Pressure distributions were measured at five locations along the blade along with detailed flow field measurements around the rotor plane using stereo PIV. As a result of the international collaboration within this task a very thorough analysis of the data could be carried out and a large number of codes were validated not only in terms of loads but also in terms of underlying flow field. The detailed pressure measurements along the blade in combination with the detailed flow field measurements gave a unique opportunity to better understand the response of a wind turbine to the incoming flow field. Deficiencies in modelling have been established and directions for model improvement can be given.

The existing and newly proposed DSM mechanisms as the achievement of the previous tasks were put into order. The arena of information exchange and discussions was prepared through use of the Internet homepage for the IEA/DSM implementation agreement. Necessary official policies were also made available. Points of precautions when the mechanisms of other countries are used in Japan: the key to the success depends on social or cultural situations that work as the base; therefore, comparisons and analyses are necessary on such elements as customers as the object, energy projects and governments; compatibility of the situation and pattern of the demand side with the DSM technologies governs the reasonability thereof; the types of the mechanisms are narrowed down by size of the customer division, consumption pattern, electric power quality and safety, and needs on the flexibility; proliferation levels of the DSM technologies determine the appropriate mechanisms; and how the DSM is conceived against the final consumption is governed by the conception by both of the customers and the government.

Short-term objectives of the IEA Bioenergy Task 40 'Sustainable International Bio-energy Trade: Securing Supply and Demand' are amongst other objectives to present an overview of development of biomass markets in various parts of the world and to identify existing barriers hampering development of a (global) commodity market (e.g. policy framework, ecology, economics). As in most countries biomass is a relatively new (though quickly growing) commodity, relatively little information is available on e.g. the traded volumes and prices of various biomass streams, policies and regulations on biomass use and trade, and existing and perceived barriers. This country report aims to provide an overview of these issues for the Netherlands and is an extended update of previous reports (2005 and 2006)

This report describes the work done during five years of the second phase of Task 3 of the photovoltaic power systems programme of the International Energy Agency (IEA-PVPS). Task 3 activities were concentrated on stand-alone photovoltaic systems with the main effort on improving the quality and reducing the cost of these systems. The work was divided in 2 sub-tasks whose first one was concentrated on quality insurance schemes and second one on technical recommendations coming from practical experience. Twelve original reports have been published covering topics that can be sorted in 4 categories: the first one is dedicated on quality issues with a review of existing standards in the participating countries and a double paper giving quality assurance recommendations on project management and examples of applying these rules in practical cases. The second category dwelled on photovoltaic systems with papers on charge controllers, on lightning protection and monitoring of systems. The third category presents interesting studies on the storage of energy which remains the main subject where improvements should be made in order to lower the cost of energy; four papers describe the management and the test procedures of lead-acid batteries, how to choose a lead-acid battery and finally are there alternatives to lead-acid batteries for the storage of photovoltaic electricity. The last category worked on loads and users of renewable energy and gives a large amount of experience with loads, how to choose them and how the energy can be better used through demand side management.

The history of the IEA. Volume four. Supplement to volumes 1, 2 et 3

International Nuclear Information System (INIS)

2004-01-01

Published in 1994, The History of the International Energy Agency: The First Twenty Years, the comprehensive story of the IEA's decisions since its founding in 1974, has been an invaluable resource to the Agency's Member country governments, to the IEA Secretariat, and to all those who are interested in international, inter-governmental organisations. The author was Richard Scott, a former IEA Legal Counsel. Now, his successor Craig S. Bamberger, has extended The History through most of the Agency's third decade, up to the end of 2003. In this Supplement to Mr. Scott's History, Mr. Bamberger has remained faithful to the structure of the original work, enabling the reader to move easily between time periods when researching a particular subject. Continuity and change are both in evidence. The IEA's basic institutional arrangements remain essentially as Mr. Scott described them in Volume I of The History, but the Supplement's extensive treatment of budget and programme of work issues reflects significant changes in Agency practice, during a period when governments were engrossed in the management and financing of international organisations generally. In the policy realm, the Supplement recounts numerous new initiatives that the IEA has launched, while remaining true to its focus on the 'three E' policy goals: Energy Security, Environmental Protection and Economic Growth

NONE

2007-11-29

When Hurricane Katrina hit the Gulf of Mexico in 2005, the region's oil production and refining infrastructure was devastated and world energy markets were disrupted. The International Energy Agency decided in a matter of days to bring 60 million barrels of additional oil to the market. The emergency response system worked - the collective action helped to stabilise global markets. Since its founding in 1974, oil supply security has been a core mission of the IEA and the Agency has improved its mechanisms to respond to short-term oil supply disruptions. Nevertheless, numerous factors will continue to test the delicate balance of supply and demand. Oil demand growth will continue to accelerate in Asia; oil will be increasingly produced by a shrinking number of countries; and capacities in the supply chain will need to expand. These are just a few of the challenges facing an already tight market. What are the emergency response systems of IEA countries? How are their emergency structures organised? How prepared is the IEA to deal with an oil supply disruption? This publication addresses these questions. It presents another cycle of rigorous reviews of the emergency response mechanisms of IEA member countries. The goal of these reviews is to ensure that the IEA stays ready to respond effectively to oil supply disruptions. This publication also includes overviews of how China, India and countries of Southeast Asia are progressing with domestic policies to improve oil supply security, based on emergency stocks.

This document has been produced to provide the definition and rationale for the Baseline Offshore Wind Farm established within IEA Wind Task 26--Cost of Wind Energy. The Baseline has been developed to provide a common starting point for country comparisons and sensitivity analysis on key offshore wind cost and value drivers. The baseline project reflects an approximate average of the characteristics of projects installed between 2012 and 2014, with the project life assumed to be 20 years. The baseline wind farm is located 40 kilometres (km) from construction and operations and maintenance (O&M) ports and from export cable landfall. The wind farm consists of 100 4-megawatt (MW) wind turbines mounted on monopile foundations in an average water depth of 25 metres (m), connected by 33-kilovolt (kV) inter-array cables. The arrays are connected to a single offshore substation (33kV/220kV) mounted on a jacket foundation, with the substation connected via a single 220kV export cable to an onshore substation, 10km from landfall. The wind farm employs a port-based O&M strategy using crew-transfer vessels.

2005-07-01

Since its creation by the International Energy Agency in the late 1970's, the IEA Hydrogen Implementing Agreement (HIA) has been at the forefront of collaborative international hydrogen research and development (R and D) (http://www.ieahia.org. ) The collective body of HIA hydrogen R and D will contribute to definition of the hydrogen economy. The five-year [2004-2009) mission of the IEA HIA is to advance the adoption of a Hydrogen Economy through strategic implementation of collaborative R and D and outreach programs that address key issues and barriers. The three goals for the Second Generation HIA are: Advancement of science and technology via pre-commercial collaborative RD and D programs; Assessment of market environment, including the non-energy sector; and Implementation of outreach program, aimed at community acceptance and support. The HIA launched its Second Generation of hydrogen R and D in the latter part of 2004. The HIA's anniversary report: In Pursuit of the Future: 25 Years of IEA Research towards the realization of Hydrogen Energy Systems (http://ieahia.org/pdfs/IEA_AnniversaryReport_HIA.pdf) chronicles its contributions to hydrogen R and D. As the hydrogen economy takes shape, the HIA is pleased to share highlights of its R and D history together with progress on planned activities and its six current annexes, listed below: Task 15 Photobiological Production of Hydrogen Task 16 Hydrogen from Carbon-Containing Materials Task 17 Solid and Liquid Storage Task 18 Integrated Systems Evaluation Task 19 Safety Task 20 Hydrogen from Waterphotolysis Planned successor annexes in storage and photobiological hydrogen production will also be discussed, along with a task on high temperature hydrogen production that is now in the definition phase. Over 250 experts from the sixteen member HIA countries and the European Union contribute to this portfolio of cutting edge hydrogen R and D and analysis activities. Several other countries are expected to

Researchers within the International Energy Agency (IEA) Task 31: Wakebench have created a framework for the evaluation of wind farm flow models operating at the microscale level. The framework consists of a model evaluation protocol integrated with a web-based portal for model benchmarking (www.windbench.net). This paper provides an overview of the building-block validation approach applied to wind farm wake models, including best practices for the benchmarking and data processing procedures for validation datasets from wind farm SCADA and meteorological databases. A hierarchy of test cases has been proposed for wake model evaluation, from similarity theory of the axisymmetric wake and idealized infinite wind farm, to single-wake wind tunnel (UMN-EPFL) and field experiments (Sexbierum), to wind farm arrays in offshore (Horns Rev, Lillgrund) and complex terrain conditions (San Gregorio). A summary of results from the axisymmetric wake, Sexbierum, Horns Rev and Lillgrund benchmarks are used to discuss the state-of-the-art of wake model validation and highlight the most relevant issues for future development.

The 2007 natural gas market review of the International energy agency (IEA) is this year subtitled: 'security in a globalizing market to 2015'. The review thus stresses on the 2006 highlights but reinforces the idea already expressed in the 2006 issue that energy security is now an inevitable topic. It offers also a prospective analysis of the natural gas market up to 2015 and devotes a full chapter to LNG development. As a matter of fact, the IEA considers that, from now to 2015, two thirds of the additional gas supplies will be in the form of LNG. The review supplies also some complements about some national markets. The present article reviews the most important points of this analysis. (J.S.)

Two of the short-term objectives of the IEA Bioenergy Task 40 are to present an overview of development of biomass markets in various parts of the world and to identify existing barriers hampering development of a (global) commodity market (e.g. policy framework, ecology, economics). As in most countries biomass is a relatively new (though quickly growing) commodity, relatively little information is available on e.g. the traded volumes and prices of various biomass streams, policies and regulations on biomass use and trade, and existing and perceived barriers. This country report aims to provide an overview of these issues for the Netherlands, and also sets the first step to make an inventory of barriers as perceived by various Dutch stakeholders. The report organizes as follows. Section 2 and 3 presents a brief overview of the policy setting on renewable energy and bio-energy in the Netherlands and the policy instruments deployed to stimulate renewable energy market penetration. In section 4, the achievements, the current status and the short-term expectations for the use of biomass energy in the Netherlands are described. Next, in section 5, the biomass market and biomass trade in the Netherlands are discussed, including the major biomass streams involved, conversion technologies, import and export volumes, biomass prices, barriers for further import and biomass certification efforts. Section 6 concludes with a general discussion and conclusions.

Rodrigues, Antonio Carlos Iglesias; Madi Filho, Tufic; Ricci Filho, Walter

2013-01-01

The IEA-R1 research reactor operates in a regimen of 64h weekly, at the power of 4.5 MW. In these conditions, the racks to the spent fuel elements have less than half of its initial capacity. Thus, maintaining these operating circumstances, the storage will have capacity for approximately six years. Whereas the estimated useful life of the IEA-R1 is around twenty years, it will be necessary to increase the storage capacity for the spent fuel. Dr. Henrik Grahn, expert of the International Atomic Energy Agency on wet storage, visiting the IEA-R1 Reactor (September/2012) made some recommendations: among them, the design and installation of racks made with borated stainless steel and internally coated with an aluminum film, so that corrosion of the fuel elements would not occur. This work objective is the project of high capacity storage for spent fuel elements, using borated stainless steel, to answer the Reactor IEA-R1 demand and the security requirements of the International Atomic Energy Agency.

2013-01-01

Last May the International Energy Agency (IEA) published an analysis of the energy transition in Germany. This analysis acknowledges the efforts made by Germany for a better energy efficiency and for the important development of renewable energies but also highlights 3 concerns. First, the cost for the energy transition is not fairly dispatched: electrical power is far more expensive for households than for enterprises. Secondly, according to the IEA, measures must be taken to restrain the growing costs of renewable energies and to foster investment to develop smart grids. Thirdly, the IEA misses the lack of coordination of Germany's energy policy with foreign countries' ones as German decisions have an impact beyond its frontiers. (A.C.)

Wind energy is now being deployed world-wide at a rapidly increasing rate and the International Energy Agency (IEA) has a changing role in its growth. IEA was founded in 1974 within the framework of the Organization for Economic Cooperation and Development (OECD) to collaborate on comprehensive international energy programs. IEA membership consists of eighteen parties from sixteen countries and the European Commission. Recently there has been increasing interest in IEA participation from both OECD and non-OECD countries. Non-OECD countries participating in various IEA Agreements include: China, India, Israel, Korea, and Russia. Because of its diverse international makeup, the IEA is viewed as a source of reliable technical and economic information. The World Bank has approached the Executive Committee for Wind Energy R & D, through the IEA Renewable Energy Working Party, to assist in the expansion of wind deployment. In addition, IEA is moving from R & D programs to include tracking of implementation incentives offered by its members.

1994-05-01

In the 12-month period 01.05.93 - 30.04.94 the Danish activities in the IEA 'Solar Cell Agreement' consisted in: participation in the Executive Committee (ExCo) and participation in Task 1 'Exchange and Dissemination of Information on PV Power Systems'. ExCo has meetings every half-year and is a coordinating organ for the Agreement. Work on the Task 1 is organized in 4 subtasks: (1) mapping of solar cell activities in the OECD countries and preparation of an IEA handbook on solar cell technology; (2) publishing of a semiannual newsletter about the agreement; (3) an 'executive conference' on solar cell technology and its uses with participation of the decision-makers in respective power industries; (4) information dissemination whenever required. Demonstration projects, like a photovoltaic roof-integrated system connected to the grid. have been implemented. Three larger solar cell projects, subsidized by the EU means, comprehend 'real time monitoring' by a solar system, WHO project 'Solar Energy Applications for Primary Health Care Clinics for Remote Rural Areas' (SAPHIR) and a grid-connected photovoltaic system in a suburb residential settlement.

2016-01-01

Within the framework of IEA SHC Task 42 / ECES Annex 29, a simple tool for the economic evaluation of thermal energy storages has been developed and tested on various existing storages. On that account, the storage capacity costs (costs per installed storage capacity) of thermal energy storages...... have been evaluated via a Top-down and a Bottom-up approach. The Top-down approach follows the assumption that the costs of energy supplied by the storage should not exceed the costs of energy from the market. The maximum acceptable storage capacity costs depend on the interest rate assigned...

Greenhouse gas balances of bioenergy systems: Programme and accomplishments of IEA Bioenergy Task XV, 1995-97

International Nuclear Information System (INIS)

Spitzer, J.

1998-01-01

The goal of IEA Bioenergy Task XV was to investigate all processes involved in using bioenergy systems, on a full fuel-cycle basis, with the aim of establishing overall greenhouse gas (GHG) balances. Task participants have been Austria, Canada, Finland, Sweden and the U.S.A. (Operating Agent: Austria). During its work period (1995-97), Task XV hosted five international workshops. The scientific achievements of the Task are documented in a number of published papers. Also, a bibliography on the research area was compiled. Much work was devoted to the question of carbon accounting in the context of the work of the Intergovernmental Panel on Climate Change (IPCC), and Task XV made contributions to a draft IPCC special report prepared for the IPCC Expert Group on Harvested Wood Products. The technical paper 'Forest harvests and wood products: sources and sinks of atmospheric carbon dioxide' (Forest Science, forthcoming) contrasts two carbon accounting approaches for considering wood products in the IPCC Guidelines (i.e., 'atmospheric-flow' vs. 'stock-change' method) and reports on estimated national carbon source-sink balances for selected countries, regions, and the world. Finally, progress was made in establishing a common analytical framework to compare different bioenergy options. The framework considers on-site carbon storage changes as well as GHG emissions from auxiliary fossil fuels, conversion efficiencies, and emission credits for by-products; comparisons between bioenergy systems and traditional fossil fuel and other energy systems as a reference are allowed, and reference land-uses accounted for. The continuation Task is Task 25 (1998-2000), with New Zealand joining the current partners 9 refs, 2 tabs

1980-10-01

The purpose of this report is to show how the objective of developing guidelines for a solar energy related portable meteorology instrument package, under the auspices of the International Energy Agency (IEA), was carried out and preliminarily demonstrated and validated. A project to develop guidelines for such packages was initiated at IEA's Solar Heating and Cooling of Buildings Program Expert's Meeting held in Norrkoping, Sweden in February 1976. An international comparison of resultant devices was conducted on behalf of the IEA at a conference held in Hamburg, Federal Republic of Germany, in 1978. Results of the 1978 Hamburg comparison of two devices and the Swiss Mobile Solar Radiation System, using German meteorological standards, are discussed. The consensus of the IEA Task Group is that the objective of the subtask has been accomplished.

Design of a new wet storage rack for spent fuels from IEA-R1 reactor

International Nuclear Information System (INIS)

Rodrigues, Antonio C.I.; Madi Filho, Tufic; Siqueira, Paulo T.D.; Ricci Filho, Walter

2015-01-01

The IEA-R1 research reactor operates in a regimen of 64h weekly, at the power of 4.5 MW. In these conditions, the racks of the spent fuel elements have less than half of its initial capacity. Thus, maintaining these operating conditions, the storage will have capacity for about six years. Since the estimated useful life of the IEA-R1 is about another 20 years, it will be necessary to increase the storage capacity of spent fuel. Dr. Henrik Grahn, expert of the International Atomic Energy Agency on wet storage, visiting the IEA-R1 Reactor (September/2012) made some recommendations: among them, the design and installation of racks made with borated stainless steel and internally coated with an aluminum film, so that corrosion of the fuel elements would not occur. After an extensive literature review of material options given for this type of application we got to Boral® manufactured by 3M due to numerous advantages. This paper presents studies on the analysis of criticality using the computer code MCNP 5, demonstrating the possibility of doubling the storage capacity of current racks to attend the demand of the IEA-R1 reactor while attending the safety requirements the International Atomic Energy Agency.

Participation was implemented to the IEA/DSM task VI as the demonstrative investigation of a new load leveling method. The DSM strategy is a means to achieve the public objectives of wide range, wherein the DSM mechanism is important, that can obtain accurate and useful information in competitive markets. Consumer protecting activities have close relation with general information needs. A financial incentive mechanism is also necessary to support nurturing of business organizations and new ESCO industries. A market forming mechanism using the DSM can solve the problem of disagreement in the incentives (for example, private profit of electric power companies and the public nature of the government). These include system plans considering the DSM, setting of upper limit in the profit, demand side bidding, and green charge institution. It is important to utilize affluent findings and means used in the past and utilize each mechanism to meet the needs for public benefit at the present and in the future, while structuring an electric power business structure incorporating the DSM. The DSM promoting mechanisms in each country were classified and put into order of regulations, supports, funds, and markets. (NEDO)

IEA Wind Task 26 - Multi-national Case Study of the Financial Cost of Wind Energy; Work Package 1 Final Report

Energy Technology Data Exchange (ETDEWEB)

Schwabe, P.; Lensink, S.; Hand, M.

2011-03-01

The lifetime cost of wind energy is comprised of a number of components including the investment cost, operation and maintenance costs, financing costs, and annual energy production. Accurate representation of these cost streams is critical in estimating a wind plant's cost of energy. Some of these cost streams will vary over the life of a given project. From the outset of project development, investors in wind energy have relatively certain knowledge of the plant's lifetime cost of wind energy. This is because a wind energy project's installed costs and mean wind speed are known early on, and wind generation generally has low variable operation and maintenance costs, zero fuel cost, and no carbon emissions cost. Despite these inherent characteristics, there are wide variations in the cost of wind energy internationally, which is the focus of this report. Using a multinational case-study approach, this work seeks to understand the sources of wind energy cost differences among seven countries under International Energy Agency (IEA) Wind Task 26 - Cost of Wind Energy. The participating countries in this study include Denmark, Germany, the Netherlands, Spain, Sweden, Switzerland, and the United States. Due to data availability, onshore wind energy is the primary focus of this study, though a small sample of reported offshore cost data is also included.

IEA SHC Task 38 'Solar Air-Conditioning and Refrigeration' ran from October 2006 to December 2010. Denmark was represented in the task from January 2007 to December 2010. The aim of the task was to encourage use of solar powered refrigeration and air conditioning systems in particular at residential, commercial and industrial sectors. Furthermore, the aim was to contribute to new research and development activities on new systems and concepts. Solar cooling is an energy efficient way to cool buildings, which can also be used in Denmark as there is a high correlation between solar radiation and the need for air conditioning. Part of the Danish team has also been the company AC Sun which in the period has worked with developing a new and revolutionary thermo-cooling technology. IEA SHC Task 38 Solar Air-Conditioning and Refrigeration was divided into 4 subtask: 1) Subtask A: Pre-engineered systems for residential and small commercial applications 2) Subtask B: Custom-made systems for large non-residential buildings and industrial applications 3) Subtask C: Modelling and fundamental analysis 4) Subtask D: Market transfer activities.

Short-term objectives of the IEA Bioenergy Task 40 'Sustainable International Bio-energy Trade: Securing Supply and Demand' are amongst other objectives to present an overview of development of biomass markets in various parts of the world and to identify existing barriers hampering development of a (global) commodity market (e.g. policy framework, ecology, economics). As in most countries biomass is a relatively new (though quickly growing) commodity, relatively little information is available on e.g. the traded volumes and prices of various biomass streams, policies and regulations on biomass use and trade, and existing and perceived barriers. This country report aims to provide an overview of these issues for the Netherlands, and also sets the first step to make an inventory of barriers as perceived by various Dutch stakeholders. The information gathered in this report is to a large extent based on existing statistics and reports from Dutch institutions. The literature data is complemented by additional information obtained from stakeholders, such as utilities, biomass traders, the port of Rotterdam, policy makers and custom institutions. In some cases, the data source was left anonymous because of the confidential nature of the data concerned. This report was first published in 2005. In this updated 2006 version, additional data has been collected for the year 2005, mainly concerning the import of biomass and renewable electricity. Also the policy section has been updated (situation September 2006), and some information on the use of biofuels has been added.

IEA countries energy policy. Report 1992

International Nuclear Information System (INIS)

1994-01-01

The International Energy Agency is interested by the energy policy of its 23 members countries. This book sums up the evolution of energy policy in 1991 and 1992, sticking particularly to energy proposal and demand, to energy efficiency, to interaction between energy and environment, to the energy technology and to research and development activities. The 23 countries are examined regularly. The elaborate examinations refer to the energy policy of each member country to dictate the common orientation of their policy. Ministers meetings of IEA take place regularly. The latest took place in PARIS on the fourth of June 1993 where the ministers confirmed that there were essential elements of the energy policy and that they recommended to all countries to take that in account in the formulation of their strategies. Beyond the examinations by country, this book contains a whole report which throws into relief the main new acts which were happened in the IEA members countries and a glimpse on the evolution of the energy situation in the no members countries. It gives specific data and informations on the governmental budgets allocated to research and development energy activities. 6 annexes, 12 graphs., 5 tabs

Analysis of Photovoltaic Applications in Zero Energy Building Cases of IEA SHC/EBC Task 40/Annex 52

2015-07-01

Full Text Available A Net Zero Energy Building (NZEB considerably reduces the building energy load through high efficiency equipment and passive elements such as building orientation, high insulation, natural daylighting, and ventilation in order to achieve zero energy balance with on-site energy production from renewable energy systems applied to the building. For a Zero Energy Building (ZEB, the heating energy demand can be significantly reduced with high insulation and air tightness, while the cooling energy demand can be curtailed by applying shading device, cross ventilation, etc. As such, the electrical energy demand for a ZEB is relatively higher than its heat energy demand. Therefore, the application of a Renewable Energy System (RES to produce electricity is necessary for a ZEB. In particular, Building Integrated Photovoltaic (BIPV systems that generate electricity can play an important role for achieving zero energy balance in buildings; BIPVs are multi-functional and there are many ways to apply them into buildings. This study comprehensively analyzes photovoltaic (PV applications in ZEB cases through the International Energy Agency Solar Heating and Cooling Programme (IEA SHC/Energy in Buildings and Communities Programme (EBC Task 40/Annex 52 activities, which include PV installation methods, PV cell type, and electricity generation. The most widely applied RES is the PV system, corresponding to 29 out of a total of 30 cases. Among the roof type PV systems, 71% were non-integrated. In addition, 14 of the 27 cases in which PV systems were applied, satisfied over 100% of the electricity energy demand from the PV system and were found to generate surplus electrical power.

A Look at the IEA 2011 Release of Strategic Oil Reserves

International Nuclear Information System (INIS)

Glick, Devin

2011-07-01

On June 23, 2011, the International Energy Agency (IEA) coordinated the release of 60 million barrels of emergency stocks in response to the disruption of oil production in Libya due to civil unrest. This announcement elicited a mixed reaction from the public and from the market. Some politicians in the United States called the move a political decision by the President to satisfy voters, private oil companies did not like the interference, and some OPEC countries were upset and called the release unnecessary. The reason why there was a strong reaction was because the IEA had never coordinated a release in this manner before. It was only the third time there had ever been a release, after the First Gulf War in 1991 and for Hurricane Katrina and Rita in 2005. The circumstance and decision for the June 23 drawdown was more flexible and may signal a change in the way strategic petroleum stocks are used. This paper examines the motivations and the potential consequences of the International Energy Agency's coordinated action to release petroleum stocks on June 23, 2011. (author)

In 2010, the International Energy Agency (IEA) and the Nuclear Energy Agency (NEA) released a Nuclear Energy Technology Road-map which outlined the steps needed to accelerate the development of nuclear power and its role in achieve deep greenhouse-gas emissions reduction. Both the global energy sector and the outlook for nuclear have changed significantly since then and an update of this Road-map is currently underway. The IEA and NEA held a stakeholder dialogue meeting focused on nuclear develop in Asia on 25 February 2014 in Hong Kong. The meeting brought together key stakeholders from industry, government, finance and other relevant organisations from Asia and beyond to help define and prioritise key items to be discussed in the IEA/NEA's Nuclear Road-map Update. One of the expected outcomes of this intensive brainstorming and Road-map development session was to discus key targets, milestones, policy measures and other actions needed to support the development and deployment of nuclear power. The workshop was organized in 3 sessions dealing with: Session 1 - Technology development needs for nuclear (Reactor technology, Fuel cycle and decommissioning); Session 2 - Breakout Discussion: - Group I: Financing nuclear. This session focussed on today's reality for financing nuclear and the current economics of nuclear. Mechanisms such as government loan guarantees, vendor financing and role of export credit agencies were discussed. Participants were asked to share lessons learnt and current practices on financing nuclear as well as recommendations (if needed) for additional policy support or changes in technology development (e.g. SMR) which would facilitate greater deployment of nuclear technologies. - Group II: Nuclear regulation and safety. This session focussed on regulatory needs for enhanced security and regulation for new build programmes, institutional development requirements for new nuclear countries.

These agreements are meant to be very flexible depending on the nature of the work and the interests of the participating countries. Many IAs are directed at the development of specific technologies, while a number of IAs are primarily used to facilitate information collection and dissemination. There are also a number of agreements that do not deal directly with technology development, but deal with environmental, economic and safety aspects of the technologies under development. The IEA Bioenergy Agreement is a prime example of how Implementing Agreements can be utilised to establish and expand cooperative research for the effective leveraging of technical knowledge and financial resources in finding solutions to the future needs of a growing energy dependent world. As will be illustrated, these activities are important to the commercialisation and deployment of bioenergy technologies, which increasingly are being visualized as one of the few options that can maintain and promote economic and environmental stability

2017-08-01

In 2012 the International Energy Agency (IEA) Heat Pump Programme (now the Heat Pump Technologies (HPT) program) established Annex 41 to investigate technology solutions to improve performance of heat pumps for cold climates. Four IEA HPT member countries are participating in the Annex – Austria, Canada, Japan, and the United States (U.S.). The principal focus of Annex 41 is on electrically driven air-source heat pumps (ASHP) since that system type has the lowest installation cost of all heat pump alternatives. They also have the most significant performance challenges given their inherent efficiency and capacity issues at cold outdoor temperatures. Availability of ASHPs with improved low ambient performance would help bring about a much stronger heat pump market presence in cold areas, which today rely predominantly on fossil fuel furnace heating systems.

Obsolete or resurgent? The International Energy Agency in a changing global landscape

Van de Graaf, Thijs

2012-01-01

Founded in response to the 1973 oil shock, the International Energy Agency (IEA) is arguably still the most important multilateral organization for energy-importing countries. Yet, the global geopolitical landscape has changed considerably since the IEA's creation. The rise of new energy consumers, new energy-related challenges and new international energy forums prompt a rethink of the agency's current role and institutional design. This article seeks to contribute to the recent debate on the future role of the IEA by examining specific drivers, avenues and constraints for institutional reform. The method used is SWOT analysis, which allows to summarize the key factors emanating from an assessment of an organization's internal characteristics (strengths and weaknesses) and its external environment (opportunities and threats). Building on this SWOT analysis, the article formulates a strategy for the IEA to remain the focal point in global energy governance. Key elements of this strategy include: stronger engagement with new consumers, rapprochement with OPEC, becoming a leading voice in the energy transition, and changing the agency's internal governance practices. - Highlights: ► The IEA is challenged by the rise of new consumers, threats and organizations. ► Assessment of the agency’s internal characteristics and external environment. ► The IEA needs to step up its outreach policy and fully embrace sustainable energy.

2003-01-01

This volume contains an analysis of developments in energy policies in the Member countries of the International Energy Agency. It features an overview of major trends in the energy markets, notably the renewed interest in energy security on the part of policy-makers. The study describes how, during the period before and during the war in Iraq, the IEA successfully worked to secure oil supply. 2003 was also a year when growing gas demand and rising import dependency in most IEA Member countries obliged energy policy makers to look at the longer term issue of security of gas supply. In addition to these external developments, an internal dimension of energy security arose in the context of electricity and gas market reform. The book also describes the efforts by countries having ratified the Kyoto Protocol to implement the agreements and the trend of energy R and D policies, as well as developments in energy security and energy market reform in major non-OECD countries. It includes: summaries of the in-depth reviews of Austria, Hungary, Italy, Ireland, Japan and Switzerland conducted from October 2002 to June 2003. The full reviews are published separately

@@ Reportedly, China's oil imports accounted for nearly one third of the world's total oil supply in 2003. The country's oil imports are estimated at 110～120 million tons in 2004,equal to 2.2～2.4 million barrels per day, much higher than 91 million tons in 2003. International Energy Agency has helped the Chinese government with the country's strategic oil stockpiling plan by offering the training. The Paris-based IEA has urged China to take into consideration how to operate and maintain the national strategic oil stockpiling system and clarify the roles of the enterprises and the State in oil stockpiling.

Energy policies of IEA countries: the Republic of Korea 2006 review

2007-07-01

Through analysis of its existing policies and comparisons with good examples in other IEA countries, this book provides critiques and recommendations for policy improvements. Covering not only traditional energy sectors, but also energy efficiency, renewables and the environment, the IEA report serves as a guide to understanding - and addressing - the energy challenges that face the modern Republic of Korea. The great strides that the Republic of Korea has made over the last three decades are not confined to its economy. Its energy industry has similarly leapt forward in terms of infrastructure and security. Though it has no links to nearby countries that would allow it to rely on electricity imports or piped natural gas, the country has rapidly electrified, built a diverse portfolio of electricity supply, developed a robust nuclear energy industry and become one of the pioneers in the liquefied natural gas trade. As the most recent member of the International Energy Agency (IEA), this progress is remarkable and its enhancement of its policy goals - adding economic efficiency and environmental sustainability to energy security - is commendable. Building on the liberalisation of its economy, the Republic of Korea set out an ambitious plan for reform of its state-controlled natural gas and electricity industries. However, the plans have been stalled and there is currently little vision for effective reform going forward. As the economy makes the transition to one with less phenomenal, more sustainable and less predictable growth, the IEA encourages the Republic of Korea to press forward with liberalisation in order to underpin a more flexible and efficient energy sector. 22 figs., 33 tabs., 3 apps.

Ground source heat is a collective name for tapping, recharging and storing thermal energy at moderate temperature in the bedrock, ground water and soil (renewable energy). By means of heat pumps, ground source heating systems can be used as highly energy efficient and environmentally-friendly heating and cooling in all kinds of buildings. IEA's heat pump programme (IEA HPP) has in the period March 2004 to June 2006 carried out an Annex on heating pump systems based on ground source heat: 'Annex 29 - Ground-source heat pumps overcoming market and technical barriers'. The project has i.a. covered the development of more cost- and energy efficient solutions, identification and analysis of market obstacles, technology transfer and the task of making visible the energy economising potential and environmental gains that this type of systems represent. The six participating countries have been Canada, Japan, Norway, Sweden, USA and Austria (operating agent). Norway's participation in IEA Annex 29 has been financed by ENOVA SF, while SINTEF Energy research AS has been in charge of planning and executing the Norwegian project activities. This report provides a general presentation of ground source heat pump systems, and gives a summary of the most important Norwegian activities in IEA Annex 29, which includes: The development of a Norwegian internet home page (http://www.energy.sintef.no/prosjekt/annex29), preparation of Norwegian status report, initiation, coordination and carrying out of Norwegian research projects and reports, communication of results (technology transfer) in Norway, networking activities towards important market actors in Norway, participation and delivering discourse at international seminars (workshops), and participation at international working sessions (ml)

Progress Implementing the IEA 25 Energy Efficiency Policy Recommendations

2012-07-01

Significantly improving energy efficiency remains a priority for all countries. Meetings of G8 leaders and IEA ministers reaffirmed the critical role that improved energy efficiency can play in addressing energy security, environmental and economic challenges. Many IEA publications have also documented the essential role of energy efficiency. For example, the World Energy Outlook and the Energy Technology Perspectives reports identify energy efficiency as the most significant contributor to achieving energy security, economic and environmental goals. Energy efficiency is clearly the “first fuel” in the delivery of energy services in the coming low-carbon energy future. To support governments in their implementation of energy efficiency, the IEA recommended the adoption of specific energy efficiency policy measures to the G8 summits in 2006, 2007 and 2008. The consolidated set of recommendations to these summits is known as the ‘IEA 25 energy efficiency policy recommendations’ because it covers 25 fields of action across seven priority areas: cross-sectoral activity, buildings, appliances, lighting, transport, industry and energy utilities. The IEA estimates that if implemented globally without delay, the proposed actions could save as much as 7.6 giga tonnes (Gt) CO2/year by 2030 – almost 1.5 times the current annual carbon dioxide (CO2) emissions of the United States. The IEA 25 energy efficiency policy recommendations were developed to address policy gaps and priorities. This has two implications. First, the recommendations do not cover the full range of energy efficiency policy activity possible. Rather, they focus on priority energy efficiency policies identified by IEA analysis. Second, while IEA analysis, the energy efficiency professional literature and engagement with experts clearly demonstrate the broad benefits of these IEA priority measures, the recommendations are not weighted to reflect the different energy end-use make up of different

2007-07-01

The IEA report takes an in-depth look at the energy challenges facing Germany, and through comparisons with good examples in other IEA countries, provides critiques and recommendations for policy improvements. The review guides the country towards a sustainable energy future. Few countries can have as great an impact on energy policy in Europe as Germany. Its large size and strategic location make it a critical component of the region's energy markets - as a result, sound energy policies and strong energy market design are a necessity. In these respects, Germany continues to make notable progress. The country has continued to reform its electricity and natural gas markets, set a timetable to phase out coal subsidies, is meeting key climate and environmental targets and is bringing energy, efficiency and environment to the top of the world agenda with its presidencies of both the G8 and European Union. The International Energy Agency (IEA) praises these efforts. Nevertheless, work remains to be done to further improve German energy policies and markets. The planned phase-out of nuclear power over the coming years would have major impacts on the country's energy mix, raising concerns about energy security, economic efficiency and environmental sustainability for the country and for Europe as a whole. Furthermore, though progress has been made, more needs to be done to set a truly level playing field for competition to develop in gas and electricity markets, which means effective unbundling of transport activities and a strongly empowered regulatory authority. Finally, the country's environmental policies, though helping meet ambitious goals, are expensive - and sometimes various policies work at cross-purposes. 22 figs., 27 tabs., 4 apps.

Lako, P.; Ros, M.E.

2007-07-01

This study aims to present a broad view of energy RTD expenditures of Belgium, Luxembourg, and the Netherlands, in the public domain and by private enterprises. Data is provided as much as possible by disaggregating into a format of the IEA (IEA code). IEA data serve as the starting point for data collection. The main task is to fill in the gaps in the database, viz.: Completing the IEA database for Belgium with regard to public energy RTD; Starting with a database of public energy RTD for Luxembourg; Collecting, retrieving, and analysing private energy RTD data for the Netherlands. The latter data, based on a 'bottom-up' approach, are compared to recent data of SenterNovem based on an R and D subsidy scheme in the Netherlands. The private energy RTD expenditures from both sources (the bottom-up approach in this study and the data of SenterNovem) are combined to one database of private energy RTD that may be used for, e.g., the IEA

The focus of the alternative fuels in combustion task of the International Energy Agency is on high efficiency engine combustion, furnace combustion, and combustion chemistry. The objectives of the task are to develop optimum combustion for dedicated fuels by fully utilizing the physical and chemical properties of synthetic and renewable fuels; a significant reduction in carbon dioxide, NOx and particulate matter emissions; determine the minimum emission levels for dedicated fuels; and meet future emission standards of engines without or with minimum after-treatment. This presentation discussed the alternative fuels task and addressed issues such as synthetic fuel properties and benefits. The anticipated future roadmap was presented along with a list of the synthetic and renewable engine fuels to be studied, such as neat oxygenates like alcohols and ethers, biogas/methane and gas combustion, fuel blends, dual fuel combustion, high cetane number diesel fuels like synthetic Fischer-Tropsch diesel fuel and hydrogenated vegetable oil, and low CN number fuels. Implementation examples were also discussed, such as fuel spray studies in optical spray bombs; combustion research in optical engines and combustion chambers; studies on reaction kinetics of combustion and emission formation; studies on fuel properties and ignition behaviour; combustion studies on research engines; combustion optimization; implementing the optimum combustion in research engines; and emission measurements. Overall milestone examples and the overall schedule of participating countries were also presented. figs.

A critical review of IEA's oil demand forecast for China

International Nuclear Information System (INIS)

Nel, Willem P.; Cooper, Christopher J.

2008-01-01

China has a rapidly growing economy with a rapidly increasing demand for oil. The International Energy Agency (IEA) investigated possible future oil demand scenarios for China in the 2006 World Energy Outlook. The debate on whether oil supplies will be constrained in the near future, because of limited new discoveries, raises the concern that the oil industry may not be able to produce sufficient oil to meet this demand. This paper examines the historical relationship between economic growth and oil consumption in a number of countries. Logistic curve characteristics are observed in the relationship between per capita economic activity and oil consumption. This research has determined that the minimum statistical (lower-bound) annual oil consumption for developed countries is 11 barrels per capita. Despite the increase reported in total energy efficiency, no developed country has been able to reduce oil consumption below this lower limit. Indeed, the IEA projections to 2030 for the OECD countries show no reduction in oil demand on a per capita basis. If this lower limit is applied to China, it is clear that the IEA projections for China are under-estimating the growth in demand for oil. This research has determined that this under-estimation could be as high as 10 million barrels per day by 2025. If proponents of Peak Oil such as Laherrere, Campbell and Deffeyes are correct about the predicted peak in oil production before 2020 then the implications of this reassessment of China's oil demand will have profound implications for mankind

The IEA Model of Short-term Energy Security

Energy Technology Data Exchange (ETDEWEB)

NONE

2011-07-01

Ensuring energy security has been at the centre of the IEA mission since its inception, following the oil crises of the early 1970s. While the security of oil supplies remains important, contemporary energy security policies must address all energy sources and cover a comprehensive range of natural, economic and political risks that affect energy sources, infrastructures and services. In response to this challenge, the IEA is currently developing a Model Of Short-term Energy Security (MOSES) to evaluate the energy security risks and resilience capacities of its member countries. The current version of MOSES covers short-term security of supply for primary energy sources and secondary fuels among IEA countries. It also lays the foundation for analysis of vulnerabilities of electricity and end-use energy sectors. MOSES contains a novel approach to analysing energy security, which can be used to identify energy security priorities, as a starting point for national energy security assessments and to track the evolution of a country's energy security profile. By grouping together countries with similar 'energy security profiles', MOSES depicts the energy security landscape of IEA countries. By extending the MOSES methodology to electricity security and energy services in the future, the IEA aims to develop a comprehensive policy-relevant perspective on global energy security. This Working Paper is intended for readers who wish to explore the MOSES methodology in depth; there is also a brochure which provides an overview of the analysis and results.

Estonia 2013: Energy Policies Beyond IEA Countries

Energy Technology Data Exchange (ETDEWEB)

NONE

2013-08-01

One of the fastest-growing economies in the OECD, Estonia is actively seeking to reduce the intensity of its energy system. Many of these efforts are focused on oil shale, which the country has been using for almost a century and which meets 70% of its energy demand. While it provides a large degree of energy security, oil shale is highly carbon-intensive. The government is seeking to lessen the negative environmental impact by phasing out old power plants and developing new technologies to reduce significantly CO2 emissions. The efforts on oil shale complement Estonia’s solid track record of modernising its overall energy system. Since restoring its independence in 1991, Estonia has fully liberalised its electricity and gas markets and attained most national energy policy targets and commitments for 2020. It has also started preparing its energy strategy to 2030, with an outlook to 2050. Estonia is also promoting energy market integration with neighbouring EU member states. The strengthening of the Baltic electricity market and its timely integration with the Nordic market, as well as the establishment of a regional gas market, are therefore key priorities for Estonia. Following its accession to the Organisation for Economic Co-operation and Development (OECD) in 2010, Estonia applied for International Energy Agency (IEA) membership in 2011. This review of Estonia’s energy policies is part of the IEA accession process. It analyses the energy policy challenges and opportunities facing Estonia, and provides critiques and recommendations for future policy improvements. It is intended to guide the country towards a more secure and sustainable energy future.

In response to threats posed to the future supply of energy and to the environment, the G8 leaders, in Gleneagles, UK in 2005, agreed to an initiative called the Gleneagles Plan of Action (GPOA) which addresses climate change, clean energy and sustainable development. In the GPOA, G8 leaders pledged to encourage the development of cleaner, more efficient and lower-emitting vehicles, and to promote their deployment by, among other means, asking the IEA to review existing standards and codes for vehicle efficiency and to identify best practices. In order to properly response to the above-mentioned requests from G8 leaders, the IEA has launched, among other activities, study on policies for 'transforming the way we use energy' focusing on end-use efficiency including the one in transport sector and made a comprehensive response to the GPOA at the 2008 G8 Summit Meeting in Japan with 25 recommendations on energy efficiency. Regarding these recommendations, the G8 leaders have proclaimed, in the G8 Hokkaido Toyako Summit Leaders Declaration, that they would maximize implementation of the IEA's 25 recommendations. This paper summarizes the IEA activities in transport sector regarding the GPOA and their findings and recommendations.

Biological hydrogen production, the production of H 2 by microorganisms, has been an active field of basic and applied research for many years. Realization of practical processes for photobiological hydrogen production from water using solar energy would result in a major, novel source of sustainable and renewable energy, without greenhouse gas emissions or environmental pollution. However, development of such processes requires significant scientific and technological advances, and long-term basic and applied R and D. This International Energy Agency (lEA) Task covers research areas and needs at the interface of basic and applied R and D which are of mutual interest to the countries and researchers participating in the lEA Hydrogen Agreement. The overall objective is to sufficiently advance the basic and early-stage applied science in this area of research over the next five years to allow an evaluation of the potential of such a technology to be developed as a practical renewable energy source for the 21st Century.

While all industrial sectors are integrating the environment concern into their culture and strategy, actors of the construction field seem to be torn between motivation and suspicion in front of this new topic. In most countries, the economic situation of the passed years for building was not suitable for investing in new long-term approaches, and the strong particularities of the building world appear as many complicating elements for introducing new concepts easily. But now the awareness for a sustainable development of all human activities is also growing in our sector, and it is time to take benefit of some favourable habits like the use of multi-criteria analysis: beyond performances, suitability for use, and durability, environmental quality criteria will just widen the actual scope of the technical assessment of building products. The first question is a double one : Who will use environmental criteria related to the building products, and for which purpose? Because actors in the field are many, we will have several distinct answers, which may call for different tools. In other industrial sectors, two approaches have been experimented: the Life Cycle Analysis (LCA) and the environmental labelling. Between LCA and green labels, several relevant tools are in development for the building products, each of them adapted to specific users and objectives, and most often of limited use in other contexts. A short review of the studies already performed on the environmental quality of glazing and windows revealed quite a small amount of available matter, and justifies the work undertaken within the programme of IEA/SHCP/Task 27, which will be presented in the third part of this paper.

After a Conceptual Design Activity (CDA) study on an International Fusion Material Irradiation Facility (IFMIF) has been launched under the auspices of the IEA, working groups and relevant tasks have been defined and agreed in an IEA-workshop that was held September 26-29 1994 at Karlsruhe. For the Test Cell System 11 tasks were identified which can be grouped into the three major fields neutronics, test matrix/users and test cell engineering. In order to discuss recently achieved results and to coordinate necessary activities for an effective design integration, a technical workshop on the Test Cell System was initiated. This workshop was organized on July 3-6 1995 by the Institute for Materials Research I at the Forschungszentrum Karlsruhe and attended by 20 specialists working in the fields neutronics, fusion materials R and D and test cell engineering in the European Union, Japan, and the United States of America. The presentations and discussions during this workshop have shown together with the elaborated lists of action items, that has been achieved in all three fields, and that from the future IFMIF experimental program for a number of materials a database covering widerspread loading conditions up to DEMO-reactor relevant end-of-life damage levels can be expected.

Renewable energy. Market and policy trends in IEA countries

International Nuclear Information System (INIS)

2004-01-01

Renewable energy has received high levels of attention in recent years as an alternative to traditional hydrocarbons. Governments, industry and consumers have adopted and promoted renewable technologies in response to concerns about energy security and the environment, and as a solution to electricity access problems in developing countries. To what degree has renewable energy gained a share in the energy mix? What lessons can be learned from efforts made thus far? Renewable Energy - Market and Policy Trends in IEA Countries reviews the experience of IEA countries after the oil crisis in the 1970's initiated a surge of investments in renewables research and development. While use of renewables has grown rapidly, they still account for only a small portion of the IEA energy mix. Hydropower, bio-energy and geothermal energy are mature technologies that contribute about 5 - 6% to primary energy supply. Solar, wind, and other new renewables have experienced rapid technology development, but as yet they represent only a small share. This work examines policies and measures that have been introduced in IEA countries to increase the cost effective deployment of renewables, reviews the objectives behind these policies, and evaluates the results. The aim is to identify best practices in order to assist governments in making future policy decisions

China will play a positive role in the global development of gas, the International Energy Agency’s (IEA) Executive Director, Maria Van der Hoeven has said in Beijing on 11 September, 2012 when launching a new IEA report: Gas Pricing and Regulation, China’s challenges and IEA experiences. In line with its aim to meet growing energy demand while shifting away from coal, China has set an ambitious goal of doubling its use of natural gas from 2011 levels by 2015. Prospects are good for significant new supplies – both domestic and imported, conventional and unconventional – to come online in the medium-term, but notable challenges remain, particularly concerning gas pricing and the institutional and regulatory landscape. While China’s circumstances are, in many respects unique, some current issues are similar to those a number of IEA countries have faced. This report highlights some key challenges China faces in its transition to greater reliance on natural gas, then explores in detail relevant experiences from IEA countries, particularly in the United Kingdom, the Netherlands, and the United States as well as the European Union (EU). Preliminary suggestions about how lessons learned in other countries could be applied to China’s situation are offered as well. The aim of this report is to provide stakeholders in China with a useful reference as they consider decisions about the evolution of the gas sector in their country.

The task of the Round Table and Information Exchange and Co-operation in R and D was to answer six key questions: what are then more recent prospects or opportunities for natural gas utilisation which justify major commitments to information exchange and R and D? How have government social or economic goals affected funding for R and D in North America, Europe and Asia? Is the move to energy service and, in some key markets, deregulation forcing natural gas companies to reassess private commitments to R and D? How well do natural gas companies or centres of excellence around the world exchange information and promote technology transfer compared with coal and electricity interests? What is the future role of governments, universities, laboratories and international agencies like IEA to eliminate duplication and to foster funding partnerships? Are there useful models of information exchange using state-of-the-art electronic data which optimise linkages among key production and consumption markets? (R.P.)

Optimizing Lidars for Wind Turbine Control Applications—Results from the IEA Wind Task 32 Workshop

Directory of Open Access Journals (Sweden)

Full Text Available IEA Wind Task 32 serves as an international platform for the research community and industry to identify and mitigate barriers to the use of lidars in wind energy applications. The workshop “Optimizing Lidar Design for Wind Energy Applications” was held in July 2016 to identify lidar system properties that are desirable for wind turbine control applications and help foster the widespread application of lidar-assisted control (LAC. One of the main barriers this workshop aimed to address is the multidisciplinary nature of LAC. Since lidar suppliers, wind turbine manufacturers, and researchers typically focus on their own areas of expertise, it is possible that current lidar systems are not optimal for control purposes. This paper summarizes the results of the workshop, addressing both practical and theoretical aspects, beginning with a review of the literature on lidar optimization for control applications. Next, barriers to the use of lidar for wind turbine control are identified, such as availability and reliability concerns, followed by practical suggestions for mitigating those barriers. From a theoretical perspective, the optimization of lidar scan patterns by minimizing the error between the measurements and the rotor effective wind speed of interest is discussed. Frequency domain methods for directly calculating measurement error using a stochastic wind field model are reviewed and applied to the optimization of several continuous wave and pulsed Doppler lidar scan patterns based on commercially-available systems. An overview of the design process for a lidar-assisted pitch controller for rotor speed regulation highlights design choices that can impact the usefulness of lidar measurements beyond scan pattern optimization. Finally, using measurements from an optimized scan pattern, it is shown that the rotor speed regulation achieved after optimizing the lidar-assisted control scenario via time domain simulations matches the performance

This report builds from a similar previous analysis (Schwabe et al., 2011) exploring the differences in cost of wind energy in 2008 among countries participating in IEA Wind Task 26 at that time. The levelized cost of energy (LCOE) is a widely recognized metric for understanding how technology, capital investment, operations, and financing impact the life-cycle cost of building and operating a wind plant. Schwabe et al. (2011) apply a spreadsheet-based cash flow model developed by the Energy Research Centre of the Netherlands (ECN) to estimate LCOE. This model is a detailed, discounted cash flow model used to represent the various cost structures in each of the participating countries from the perspective of a financial investor in a domestic wind energy project. This model is used for the present analysis as well, and comparisons are made for those countries who contributed to both reports, Denmark, Germany, and the United States.

The IEA HPT Annex 40 "Heat pump concepts for Nearly Zero Energy Buildings" deals with the application of heat pumps as a core component of the HVAC system for Nearly or Net Zero energy buildings (nZEB). This report covers Task 2 on the system comparison and optimisation and Task 3 dedicated to the development of adapted technologies for nZEB and field monitoring results of heat pump systems in nZEB. In the US team three institutions are involved and have worked on the following projects: The Oak Ridge National Laboratory (ORNL) will summarize development activities through the field demonstration stage for several integrated heat pump (IHP) systems electric ground-source (GS-IHP) and air-source (AS-IHP) versions and an engine driven AS-IHP version. The first commercial GS-IHP product was just introduced to the market in December 2012. This work is a contribution to Task 3 of the Annex. The University of Maryland will contribute a software development project to Task 2 of the Annex. The software ThermCom evaluates occupied space thermal comfort conditions accounting for all radiative and convective heat transfer effects as well as local air properties. The National Institute of Standards and Technology (NIST) is working on a field study effort on the NIST Net Zero Energy Residential Test Facility (NZERTF). This residential building was constructed on the NIST campus and officially opened in summer 2013. During the first year, between July 2013 and June 2014, baseline performance of the NZERTF was monitored under a simulated occupancy protocol. The house was equipped with an air-to-air heat pump which included a dedicated dehumidification operating mode. Outdoor conditions, internal loads and modes of heat pump operation were monitored. Field study results with respect to heat pump operation will be reported and recommendations on heat pump optimization for a net zero energy building will be provided. This work is a contribution to Task 3 of the Annex.

This paper presents a preliminary RELAP5 model for the IEA-R1 core. The power distribution is supplied by the neutronic code, CITATION. The main objective is to model the IEA-R1 core and validate the model through the comparison of the results to the ones from COBRA and PARET, which were used in the Final Safety Analysis Report (FSAR) for this plant. Preliminary calculations regarding some simulations are presented. Boundary conditions are simulated through time dependent components. Results obtained are compared to those available for the IEA-R1. This study will be continued considering a model for the whole plant. Important transient and accidents will be analysed in order to verify the Emergency Core Cooling System - ECCS efficiency to hold its function as projected to preserve the integrity of the reactor core and guarantee its cooling.

Energy policies of IEA countries. Canada 1996 review

International Nuclear Information System (INIS)

1996-01-01

This IEA report provides a comprehensive, in-depth assessment of the energy policies of Canada, including recommendations on future policy developments. The report acknowledges the marked shift of federal energy policy in the last decade away from heavy intervention to a more market-based approach. This has increased the strength and competitive position of Canada's energy producers, especially in oil and gas, and has provided more choice for consumers. Electricity, however, is an area that could benefit from a more market-based policy orientation. Federal provincial co-ordination is of fundamental importance. Other key issues highlighted in the review include the opportunities and challenges of international agreements on the environment, which increasingly drive energy policy decision-making; the adequacy and effectiveness of programmes to promote energy efficiency; and the balance and direction of energy research and development efforts. This report forms part of a series of periodic in-depth reviews conducted and discussed by the IEA Member countries on a four-year cycle. Short reviews of energy policy developments in all twenty-three Member countries are published annually in Energy Policies of IEA Countries. (author)

IEA joint action. Aerodynamics of wind turbines

Energy Technology Data Exchange (ETDEWEB)

Maribo Pedersen, B. [ed.

1997-12-31

In the period 1992-1997 the IEA Annex XIV `Field Rotor Aerodynamics` was carried out. Within its framework 5 institutes from 4 different countries participated in performing detailed aerodynamic measurements on full-scale wind turbines. The Annex was successfully completed and resulted in a unique database of aerodynamic measurements. The database is stored on an ECN disc (available through ftp) and on a CD-ROM. It is expected that this base will be used extensively in the development and validation of new aerodynamic models. Nevertheless at the end of IEA Annex XIV, it was recommended to perform a new IEA Annex due to the following reasons: In Annex XIV several data exchange rounds appeared to be necessary before a satisfactory result was achieved. This is due to the huge amount of data which had to be supplied, by which a thorough inspection of all data is very difficult and very time consuming; Most experimental facilities are still operational and new, very useful, measurements are expected in the near future; The definition of angle of attack and dynamic pressure in the rotating environment is less straightforward than in the wind tunnel. The conclusion from Annex XIV was that the uncertainty which results from these different definitions is still too large and more investigation in this field is required. (EG)

Nuclear energy in a low carbon future: updating the IEA/NEA nuclear technology road-map

International Nuclear Information System (INIS)

Paillere, H.; Cameron, R.; ); Tam, C.; )

2014-01-01

The Nuclear Technology road-map is one of 20 technology road-maps which the International Energy Agency (IEA) has published. The 2010 road-map, produced jointly by the IEA and the OECD Nuclear Energy Agency (NEA), came out in a year which saw 16 new construction starts, a number that had not been reached since 1985. The IEA's Energy Technology Perspectives (ETP) 'Blue Map' scenario, also published in 2010, projected at that time that the installed world nuclear capacity would need to reach 1200 GW (gross) by 2050 as part of a global effort to de-carbonise the electricity sector assuming least cost optimisation. The 'nuclear renaissance' then stalled for a number of reasons which include the consequences of the accident at the Fukushima Daiichi nuclear power plant in March 2011 on public acceptance and energy policies. The economic crisis that was already looming in 2010, as well as delays and cost overruns in the first Generation III new build projects in Europe also played a role in the significant drop in new projects. Finally, the US shale gas revolution and the potential role that unconventional oil and gas could play have also changed the prospects for nuclear development in many countries. Four years after the publication of the first road-map, the IEA and the NEA are updating the nuclear energy road-map, taking into account the recent challenges facing the development of this technology. The presentation of this paper will explain the process followed to update the road-map, through stakeholder engagement workshops that took place between January and April 2014. It will most importantly provide some insight into its contents and preliminary milestones and recommendations. The draft of the road-map will be peer-reviewed over the summer and will be published at the end of 2014. The vision developed in the road-map still relates to the contribution that nuclear energy can make to the de-carbonisation of the power system, described in

IEA Annex 26: Advanced Supermarket Refrigeration/Heat Recovery Systems

Energy Technology Data Exchange (ETDEWEB)

Baxter, VAN

2003-05-19

With increased concern about the impact of refrigerant leakage on global warming, a number of new supermarket refrigeration system configurations requiring significantly less refrigerant charge are being considered. In order to help promote the development of advanced systems and expand the knowledge base for energy-efficient supermarket technology, the International Energy Agency (IEA) established IEA Annex 26 (Advanced Supermarket Refrigeration/Heat Recovery Systems) under the ''IEA Implementing Agreement on Heat Pumping Technologies''. Annex 26 focuses on demonstrating and documenting the energy saving and environmental benefits of advanced systems design for food refrigeration and space heating and cooling for supermarkets. Advanced in this context means systems that use less energy, require less refrigerant and produce lower refrigerant emissions. Stated another way, the goal is to identify supermarket refrigeration and HVAC technology options that reduce the total equivalent warming impact (TEWI) of supermarkets by reducing both system energy use (increasing efficiency) and reducing total refrigerant charge. The Annex has five participating countries: Canada, Denmark, Sweden, the United Kingdom, and the United States. The working program of the Annex has involved analytical and experimental investigation of several candidate system design approaches to determine their potential to reduce refrigerant usage and energy consumption. Advanced refrigeration system types investigated include the following: distributed compressor systems--small parallel compressor racks are located in close proximity to the food display cases they serve thus significantly shortening the connecting refrigerant line lengths; secondary loop systems--one or more central chillers are used to refrigerate a secondary coolant (e.g. brine, ice slurry, or CO2) that is pumped to the food display cases on the sales floor; self-contained display cases--each food display case

Energy policies of IEA countries. Sweden 1996 review

International Nuclear Information System (INIS)

1996-01-01

This IEA report provides a comprehensive, in-depth assessment of the energy policies of Sweden, including recommendations on future policy developments. Electricity is a focal point of Sweden's energy policy. After a shift in the energy mix to favour electricity in the early 1970's, nuclear and hydro power each make up about half of the electricity supply. Two key events have occurred since then: the 1980 referendum, which calls for the phase-out of all nuclear plants by 2010; the recent restructuring and liberalization of the electricity sector with the creation of a Nordic electricity market. In this context, the report argues the case for making a decision now on the nuclear issue to clarify Sweden's electricity future. Other key issues highlighted in the report include Sweden's use of economic policy instruments such as a carbon tax to achieve energy and environment goals, and the adequacy and effectiveness of government efforts to promote biofuels and energy efficiency. This report forms part of a series of periodic in-depth reviews conducted and discussed by the IEA Member countries on a four-year cycle. Short reviews of energy policy developments in all twenty-three Member countries are published annually in Energy Policies of IEA Countries. (author). 13 figs., 9 tabs., 4 appends

Fainer, Gerson; Faloppa, Altair A.; Oliveira, Carlos A. de; Mattar Neto, Miguel

2015-01-01

A partial replacement of the IEA-R1 piping system was conducted in 2014. The aim of this work is to perform the stress analysis of the renewed primary piping system of the IEA-R1, taking into account the as built conditions and the pipe modifications. The nuclear research reactor IEA-R1 is a pool type reactor designed by Babcox-Willcox, which is operated by IPEN since 1957. The primary coolant system is responsible for removing the residual heat of the Reactor core. As a part of the life management, a regular inspection detected some degradation in the primary piping system. In consequence, part of the piping system was replaced. The partial renewing of the primary piping system did not imply in major piping layout modifications. However, the stress condition of the piping systems had to be reanalyzed. The structural stress analysis of the primary piping systems is now presented and the final results are discussed. (author)

Partner Country Series: Gas Pricing - China's Challenges and IEA Experience

2012-07-01

China will play a positive role in the global development of gas, the International Energy Agency’s (IEA) Executive Director, Maria Van der Hoeven has said in Beijing on 11 September, 2012 when launching a new IEA report: Gas Pricing and Regulation, China’s challenges and IEA experiences. In line with its aim to meet growing energy demand while shifting away from coal, China has set an ambitious goal of doubling its use of natural gas from 2011 levels by 2015. Prospects are good for significant new supplies – both domestic and imported, conventional and unconventional – to come online in the medium-term, but notable challenges remain, particularly concerning gas pricing and the institutional and regulatory landscape. While China’s circumstances are, in many respects unique, some current issues are similar to those a number of IEA countries have faced. This report highlights some key challenges China faces in its transition to greater reliance on natural gas, then explores in detail relevant experiences from IEA countries, particularly in the United Kingdom, the Netherlands, and the United States as well as the European Union (EU). Preliminary suggestions about how lessons learned in other countries could be applied to China’s situation are offered as well. The aim of this report is to provide stakeholders in China with a useful reference as they consider decisions about the evolution of the gas sector in their country.

Current electricity markets in Europe and the USA are drastically changing due to the introduction of competition principle and the reconsideration of business systems. Are also changing the activities and their forms of DSM (demand side management) for load leveling which has been conventionally conducted by electricity companies for the efficient operation of facilities. Task IV and Task VI aim at developing new mechanisms to promote DSM in the changing electricity markets as well as disseminating and communicating information on the new mechanism. Japan participates in Sub-task IV/6 and 7 and Task VI. Activities for developing new mechanisms are divided into Phase 1 and Phase 2. The Phase 1 includes review of existing mechanisms and preliminary development and evaluation of new mechanisms. The Phase 2 includes the detailed development of new mechanisms and evaluation criteria, communication and information about mechanisms, and identification of the public policy implications which would follow a decision by the responsible authorities to implement each of various DSM mechanisms. The time frame of Phase 1 is between February 1996 and March 1997, and that of Phase 2 is between January 1997 and December 1999. 2 figs., 4 tabs.

Vacuum insulation - Panel properties and building applications. HiPTI - High Performance Thermal Insulation - IEA/ECBCS Annex 39 - Final report

Energy Technology Data Exchange (ETDEWEB)

Erb, M. (ed.)

2005-12-15

This paper takes a look at the properties of vacuum insulation panels (VIP) that have already been developed some time ago for use in appliances such as refrigerators and deep-freezers. Their insulation performance is a factor of five to ten times better than that of conventional insulation. The paper discusses the use of such panels in buildings to provide thin, highly-insulating constructions for walls, roofs and floors. The motivation for examining the applicability of high performance thermal insulation in buildings is discussed, including solutions where severe space limitations and other technical and aesthetic considerations exist. The use of nano-structured materials and laminated foils is examined and discussed. The questions arising from the use of such panels in buildings is discussed and the open questions and risks involved are examined. Finally, an outlook on the introduction of VIP technology is presented and quality assurance aspects are examined. This work was done within the framework of the Task 39 'High Performance Thermal Insulation' of the 'Energy Conservation in Buildings and Community Systems ECBCS' programme of the International Energy Agency IEA.

A guidebook for insulated low-slope roof systems. IEA Annex 19, Low-slope roof systems: International Energy Agency Energy Conservation in Buildings and Community Systems Programme

Energy Technology Data Exchange (ETDEWEB)

1994-02-01

Low-slope roof systems are common on commercial and industrial buildings and, to a lesser extent, on residential buildings. Although insulating materials have nearly always been a component of low-slope roofs, the amount of insulation used has increased in the past two decades because of escalation of heating and cooling costs and increased awareness of the need for energy conservation. As the amount of insulation has increased, the demand has intensified for design, installation, and maintenance information specifically for well-insulated roofs. Existing practices for design, installation, and maintenance of insulated roofs have evolved from experience. Typically, these practices feature compromises due to the different properties of materials making up a given roof system. Therefore, they should be examined from time to time to ensure that they are appropriate as new materials continue to enter the market and as the data base on existing systems expands. A primary purpose of this International Energy Agency (IEA) study is to assess current roofing insulation practices in the context of an accumulating data base on performance.

Energy technologies at the cutting edge: international energy technology collaboration IEA Implementing Agreements

Energy Technology Data Exchange (ETDEWEB)

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.

Body ownership and agency: task-dependent effects of the virtual hand illusion on proprioceptive drift.

Shibuya, Satoshi; Unenaka, Satoshi; Ohki, Yukari

2017-01-01

Body ownership and agency are fundamental to self-consciousness. These bodily experiences have been intensively investigated using the rubber hand illusion, wherein participants perceive a fake hand as their own. After presentation of the illusion, the position of the participant's hand then shifts toward the location of the fake hand (proprioceptive drift). However, it remains controversial whether proprioceptive drift is able to provide an objective measurement of body ownership, and whether agency also affects drift. Using the virtual hand illusion (VHI), the current study examined the effects of body ownership and agency on proprioceptive drift, with three different visuo-motor tasks. Twenty healthy adults (29.6 ± 9.2 years old) completed VH manipulations using their right hand under a 2 × 2 factorial design (active vs. passive manipulation, and congruent vs. incongruent virtual hand). Prior to and after VH manipulation, three different tasks were performed to assess proprioceptive drift, in which participants were unable to see their real hands. The effects of the VHI on proprioceptive drift were task-dependent. When participants were required to judge the position of their right hand using a ruler, or by reaching toward a visual target, both body ownership and agency modulated proprioceptive drift. Comparatively, when participants aligned both hands, drift was influenced by ownership but not agency. These results suggest that body ownership and agency might differentially modulate various body representations in the brain.

Materials related to IEA Greenhouse Gas Rand D Program (IEA/GHG) were analyzed. The Sleipner carbon dioxide underground storage workshop is acting to narrow themes for understanding the technologies, observation methods, and research activities. The IEA/GHG has verified the known facts about ocean storage of carbon dioxide, and discussed the important development targets. Researches were made on improving methane recovery efficiency and the possibility of sealing carbon dioxide by injecting carbon dioxide in order to improve recovery of carbon bed methane. The IEA/GHG has developed a methodology for complete fuel cycles of LNG, and evaluated cost and benefit of reducing greenhouse effect gas emission. A process combining electric power generation, carbon dioxide absorption and hot heat energy utilization can reduce emission of carbon dioxide into atmosphere at relatively low cost and low energy loss. The paper also describes reduction of greenhouse effect gas emitted from cement factories, petroleum refining and petro-chemical industries, and offshore petroleum and gas facilities. It also describes influence of forestry on carbon absorption and timber markets. Case studies have discussed effects of modifying power generation plants. (NEDO)

The IEA published 'Energy Technology Perspectives' (ETP) in June 2008. That document reports on IEA scenarios for baseline and low-CO 2 alternative scenarios to 2050, across the energy economy. The study included creating scenarios for transport, using the IEA Mobility Model (MoMo). This paper reports on the transport-related ETP scenarios and describes the model used in the analysis. According to the ETP Baseline scenario, world transport energy use and CO 2 emissions will more than double by 2050. In the most challenging scenario, called 'BLUE', transport emissions are reduced by 70% in 2050 compared to their baseline level in that year (and about 25% below their 2005 levels). There are several versions of the BLUE scenario, but all involve: a 50% or greater improvement in LDV efficiency, 30-50% improvement in efficiency of other modes (e.g. trucks, ships and aircraft), 25% substitution of liquid fossil fuels by biofuels, and considerable penetration of electric and/or fuel-cell vehicles. In the second half of this paper, an overview of the MoMo model is provided. Details on the complete analysis are contained in the ETP 2008 document, available at (www.iea.org). Details of the LDV fuel economy analysis are contained in a separate paper in this collection.

2009-01-01

As a computational fluid mechanics training task, a preliminary model was developed. ANSYS-CFX R code was used in order to study the flow at the inlet nozzle of the heat exchanger of the primary circuit of the nuclear research reactor IEA-R1. The geometry of the inlet nozzle is basically compounded by a cylinder and two radial rings which are welded on the shell. When doing so there is an offset between the holes through the shell and the inlet nozzle. Since it is not standardized by TEMA, the inlet nozzle was chosen for a preliminary study of the flow. Results for the proposed model are presented and discussed. (author)

2014-02-01

Full Text Available It is commonly claimed that assessing the effectiveness of International Environmental Agreements (IEAs from the environmental problem-solving perspective is challenging because environmental data are not available. However, not much research has been done on the characterization of the nature and causes of such data unavailability. This article analyzes the term “data unavailability” and provides three typologies for data unavailability: (a “true unavailability,” where data collection complexities and resource constraints limit data collection and analysis; (b “false unavailability,” which refers to the existence of relevant data, but failure to report due to various causes; and (c “external availability,” which refers to the existence of relevant data in several organizations and research institutions, but with no established networks for data sharing between such institutions and the IEA institutions. This article discusses the causes for the various types of data unavailability and makes recommendations for promoting data availability.

The Research Reactor IEA-R1 placed at IPEN/CNEN-SP is of the swimming pool type, light water moderated and with graphite reflectors, and was build and designed by Babcock and Wilcox Co. Start up operation was in September the 16{sup th}, 1957, being the first criticality for South Hemisphere. Although designed to operate at 5 MW, the IEA-R1 was operated until 2001 with 2 MW and was suitable for use in basic and applied research as well as the production of medical radioisotopes, industry and natural sciences applications. Due to a recent demand increase on radioisotopes in Brazil for medical diagnoses and therapies applications, IPEN /CNEN updated the IEA-R1 power to 5 MW and to work at continuous operation regime. Studies on the Ageing Management for the Research Reactor IEA-R1 were conducted according to IAEA procedures. As result of these studies critical components within the Ageing Management Program were identified. Also were made recommendations on the implementation of test scheduling and standardization procedures to organize data and documents. One of the main results was the need of monitoring the two heat exchangers, the two primary circuit pumps and the data acquisition system. During monitoring procedures, issues were observed on the IEA-R1 operation at 5 MW mainly due to the ageing of the Babcox and Wilcox TCA heat exchanger, and excessive vibrations at high flow rates on CBC's TCB heat exchanger. So, from 2005 on, it was decided to work with 3,5 MW and provide a new IESA heat exchanger with 5 MW capacity, to substitute the TCA heat exchanger. This work presents results on the commissioning of the new heat exchanger and compares against the values calculated in the IESA project. The results show that the IEA-R1 Reactor can be operated more safety and continuously at 5 MW with the new IESA heat exchanger. (author)

2010-04-12

Canada, with its diverse and balanced portfolio of energy resources, is one of the largest producers and exporters of energy among IEA member countries. The energy sector plays an increasingly important role for the Canadian economy and for global energy security, as its abundant resource base has the potential to deliver even greater volumes of energy. The federal, provincial and territorial governments of Canada are all strongly committed to the sustainable development of the country's natural resources and have a long-standing and informed awareness of the need for each to contribute to the development of the energy sector. Furthermore, the government of Canada seeks to achieve a balance between the environmentally responsible production and use of energy, the growth and competitiveness of the economy, and secure and competitively priced energy and infrastructure. Nonetheless, the long-term sustainability of the sector remains a challenge. Due to climatic, geographic and other factors, Canada is one of the highest per-capita CO2 emitters in the OECD and has higher energy intensity than any IEA member country. A comprehensive national energy efficiency strategy, coupled with a coordinated climate change policy targeted at the key emitting sectors, is needed. Carbon capture and storage (CCS) is a priority for the federal government and presents Canada with an opportunity to develop a new technology that can reduce greenhouse gas emissions on a large scale. The IEA recommends that Canada provide international leadership in the development of CCS technology. This review analyses the energy challenges facing Canada and provides sectoral critiques and recommendations for further policy improvements. It is intended to help guide Canada towards a more sustainable energy future.

The World Energy Outlook 2010 is a comprehensive energy report issued by the IEA. It is rewritten annually to reflect the world's changing energy and economy realities; it also introduces new issues relevant to the energy sector. This year it dealt with Caspian Energy, Energy Poverty and Energy Subsidies. WEO is controversial in few aspects; it still promotes a 450 Scenario which has become out of reach. This year however it introduced a more realistic New Policies Scenario which will need a lot of good will and investments to accomplish. Governmental policies are going to chart future energy sector performance; increasingly this is becoming decided by non-OECD countries. A more pragmatic future energy outlook is needed to reflect developing countries priorities for growth and utilization of local resources and how to accommodate this with abatement priorities through energy efficiency measures and technologies. - Research highlights: → We critically review the findings of the IEA - World Energy Outlook 2010. → The main '450 Scenario' is no longer realistic. → Some of the other indicators like the Energy Development Index are also critically reviewed and improvements proposed.

Non destructive burn up determination of IEA-R1 reactor fuel elements by gamma-ray spectrometry using a Ge(Li) detector

International Nuclear Information System (INIS)

Madi Filho, T.

1982-01-01

A non destructive determination of burn up of low (IEA-14) and high (IEA-80) activity fuel elements used in the IEA-R1 pool reactor was made from the measured distribution of the Cs-137 gamma-ray activity in these elements. For both series of measurements a 73,7 c.c. Ge(Li) detector was used in 'well collimated' geometry. Where as IEA-14, removed from the reactor some 20 years, showed a gamma-ray spectrum essentially due to Cs-137, IEA-80, with a cooling time of 5 years, showed a more complex spectrum due to the greater number of fission products remaining. The S.I out-of-pool assembly was calibrated using Cs-137 and Co-60 point and Ag-110m plane sources. These measurements provided the necessary constants used to calculate fuel burn-up from measured relative activity distributions of fuel elements. Detailed fuel plate transmission measurements made with the Cs-137 source showed the plates to be highly homogeneous. High activity fuel elements were measured in the S.II in-pool assembly in which the detector was locate on the moveable pool bridge and the test element was positioned immediately below the detector 2.17m below the pool surface. Measurements made in the S.II assembly were normalised with respect to the measured activity of the IEA-14 element. The measured burn up of the IEA-14 and IEA-80 elements obtained in this work is 3.22.10 - 3 gms and 24.44gms. These values may be compared with respective values of 2.63.10 - 3 gms and 61.11gms given by 'total reactor energy/flux distribution' calculations. Calculated errors for the U-235 burn up are 7.4% (IEA-14) and 10.1% (IEA-80). A detailed evaluation of the errors associated with both sets of measurements is given. (Author) [pt

The group is established under the OES Energy Technology Network program under the International Energy Agency. OES was founded in 2001 and Task 10 was proposed by Bob Thresher (National Renewable Energy Laboratory) in 2015 and approved by the OES Executive Committee EXCO in 2016. The kickoff workshop took place in September 2016, wherein the initial baseline task was defined. Experience from similar offshore wind validation/verification projects (OC3-OC5 conducted within the International Energy Agency Wind Task 30) [1], [2] showed that a simple test case would help the initial cooperation to present results in a comparable way. A heaving sphere was chosen as the first test case. The team of project participants simulated different numerical experiments, such as heave decay tests and regular and irregular wave cases. The simulation results are presented and discussed in this paper.

At their Gleneagles Summit in July 2005, G8 leaders identified climate change and securing clean energy and sustainable development as key global challenges. They agreed that we must transform the way we use energy and that we must start now. Improved energy efficiency is essential to meeting this goal. Therefore, the G8 asked the IEA to provide analysis of energy use and efficiency developments in buildings, appliances, transport and industry. This publication is a response to the G8 request. Looking back, it shows how changes in energy efficiency, economic structure, income, prices and fuel mix have affected recent trends in energy use and CO2 emissions in IEA countries. The results are a 'wake-up call' for us all. Since 1990, the rate of energy efficiency improvement in IEA countries has been less than 1% per year - much lower than in previous decades and not nearly enough to stem the growth of CO2 emissions. If we are to tackle climate change and move towards a sustainable energy future then this rate will need to double. We must - and we can - do better. By means of in-depth energy indicators, this publication provides important insights to policy-makers about current energy use and CO2 emission patterns that will help shape priorities for future action.

This report aims to provide a document that gives guidance on the issue of biomass energy policies in OECD countries. The main conclusions and messages from this project were published in a joint IEA RETD and IEA Bioenergy Position Paper and presented at the COP15 in December 2009. As the main contributor to renewable energy around the world (about 10% of total energy consumption), the term 'biomass for energy' covers a broad range of products, including traditional use of wood for cooking and heating, industrial process heat, co-firing of biomass in coal-based power plants, biogas and biofuels. In many OECD countries, bioenergy is deployed to reduce fossil fuel use and improve security of supply, reduce greenhouse gas emissions and/or create new employment. Modern biomass can be more expensive than its fossil competitors, however, and there is evidence that biomass, unless produced sustainable, could have significant negative environmental and socio-economic impacts. This report elaborates on how to improve the use of biomass for energy. It assesses and provides guidelines on how to make better use of sustainable biomass potential and how to increase the positive and reduce the negative impacts.

2010-10-15

The final report for IEA Wind Task 23, Offshore Wind Energy Technology and Deployment, is made up of two separate reports: Subtask 1: Experience with Critical Deployment Issues and Subtask 2: Offshore Code Comparison Collaborative (OC3). The Subtask 1 report included here provides background information and objectives of Task 23. It specifically discusses ecological issues and regulation, electrical system integration and offshore wind, external conditions, and key conclusions for Subtask 1. A comprehensive approach to planning is needed that integrates impacts on ecology, the effects of electrical infrastructure, and the layout of wind farms. Governments, which usually finance ecological research, should disclose results for wide dissemination as they become available. As example the workshop held suggested that documents covering the issues like offshore wind energy legislation, Guidelines for EIAs and SEAs and best practices need to be produced and distributed on a regular basis, as ecological research progresses and experience from the planning and operation of existing wind farms emerges. Research should help strike the balance between optimum regulation and the need to get projects up and running. Such research is needed to increase understanding of offshore wind metrology and its impact on electrical power fluctuations. More work is needed to develop special grid code and standards for offshore. The transient behavior of large cable installations (switching / harmonic/ Behavior and modeling of large HV cable systems) must be better understood. Connection and control systems must be developed for large offshore wind farms. Work is needed to develop the technical architecture of offshore wind grid systems. Public access to measurements (e.g., turbine power output, meteorological masts, buoys) is important, especially for model validation. Determining wake effects is currently the most important challenge in wind engineering. Emphasis should be put into

Energy policies of IEA countries: Sweden - 2008 review

Energy Technology Data Exchange (ETDEWEB)

NONE

2008-05-15

Sweden is one of the leading IEA countries in the use of renewable energy and has a long tradition of ambitious and successful policies to improve energy efficiency. Compared to the other IEA countries, Sweden's CO2 emissions per capita and per unit of GDP are low, partly owing to efficient and low-carbon space heating, and virtually carbon-free electricity generation. The country also remains a forerunner in electricity market liberalisation. Still, even if Sweden has continued to make progress in most areas of its energy policy since the IEA last conducted an in-depth review in 2004, there is room for improvement. As Sweden plans to further increase the use of renewable energy, it is crucial that these supplies are produced and used in the most sustainable manner for the environment and the economy as a whole. With regard to CO2 emissions, more can be done in all sectors, but as transport is the largest polluter and its emissions are increasing, it is the logical focus for Sweden's efforts to reduce emissions further. This is a significant challenge. Nuclear provides almost half of the electricity in Sweden, at a low cost and without CO2 emissions. But the future of nuclear power in the national power mix is still uncertain. To provide clear guidance to the electricity sector, Sweden will need to resolve the ambiguity about the future of nuclear power in the country. This review analyses the energy challenges facing Sweden and provides critiques and recommendations for further policy improvements. It is intended to provide input to Swedish energy policy makers to help them identify a path towards a more sustainable energy future.

1980-10-01

Recognizing a need for a coordinated approach to resolve energy problems, certain members of the Organization for Economic Cooperation and Development (OECD) met in September 1974 and agreed to develop an International Energy Program. The International Energy Agency (IEA) was established within the OECD to administer, monitor and execute this International Energy Program. In July 1975, Solar Heating and Cooling was selected as one of the sixteen technology fields for multilateral cooperation. Five project areas, called tasks, were identified for cooperative activities within the IEA Program to Develop and Test Solar Heating and Cooling Systems. The objective of one task was to obtain improved basic resource information for the design and operation of solar heating and cooling systems through a better understanding of the required insolation (solar radiation) and related weather data, and through improved techniques for measurement and evaluation of such data. At the February 1976 initial experts meeting in Norrkoeping, Sweden, the participants developed the objective statement into two subtasks. (1) an insolation handbook; and (2) a portable meteorological instrument package. This handbook is the product of the first subtask. The objective of this handbook is to provide a basis for a dialogue between solar scientists and meteorologists. Introducing the solar scientist to solar radiation and related meteorological data enables him to better express his scientific and engineering needs to the meteorologist; and introducing the meteorologist to the special solar radiation and meteorological data applications of the solar scientist enables him to better meet the needs of the solar energy community.

Study and project of the new rack with boron for storage of fuel elements burned in the IEA-R1 research reactor

Rodrigues, Antonio Carlos Iglesias; Madi Filho, Tufic; Silva, Davilson Gomes da

2017-01-01

The IEA-R1 research reactor works 40h weekly with 4.5 Mw power. The storage rack for spent fuel elements has less than half of its initial capacity. Under these conditions (current conditions of reactor operation 32h weekly will have 3 spend fuel by year, then, approximately 3 utilization rate Positions/year). Thus, we will have only about six years of capacity for storage. Whereas the desired service life of the IEA-R1 is at least another 20 years, it will be necessary to increase the storage capacity of spent fuel. Hence, it is necessary to double the wet storage capacity (storage in the IEA-R1 reactor's pool). After reviewing the literature about materials available for use in the construction of the new storage rack with absorber of neutrons, the BoralcanTM (manufactured by 3TMhis) was chosen due to its properties. This work presents studies: (a) for the construction of new storages racks with double of the current capacity using the same place of current storages racks and (b) criticality analysis using the MCNP-5 code. Two American Nuclear Data Library were used: ENDF / B-VI and ENDF / B-VII, and the results obtained for each data bases were compared. These analyzes confirm the possibility of doubling the storage capacity of fuel elements burned in the same place occupied by the current storage rack attending to the IEA-R1 reactor needs and attending the safety requirements according to the National Nuclear Energy Commission - CNEN and the International Atomic Energy Agency (IAEA). To calculate the k eff were considered new fuel elements (maximum possible reactivity) used in full charge of the storage rack. With the results obtained in the simulation we can conclude that doubling the amount of racks for spent fuel elements are complied with safety limits established in the IAEA standards and CNEN of criticality (keff < 0.95).

The knowledge of the neutron flux distribution in research reactors is important because it gives the power distribution over the core, and it provides better conditions to perform experiments and sample irradiations. The measured neutron flux distribution can also be of interest as a means of comparison for the calculational methods of reactor analysis currently in use at this institute. The thermal neutron flux distribution of the IEA-R1 reactor has been measured with the miniature chamber WL-23292. For carrying out the measurements, it was buit a guide system that permit the insertion of the mini-chamber i between the fuel of the fuel elements. It can be introduced in two diferent positions a fuel element and in each it spans 26 axial positions. With this guide system the thermal neutron flux distribution of the IEA-R1 nuclear reactor can be obtained in a fast and efficient manner. The element measured flux distribution shows clearly the effects of control rods and reflectors in the IEA-R1 reactor. The difficulties encountered during the measurements are mentioned with detail as well as the procedures adopteed to overcome them. (Author) [pt

New Zealand faces some serious energy sector challenges, requiring special attention to security of supply issues, both in oil and gas domains. Natural gas production from the major Maui field is rapidly declining. New Zealand's greenhouse gas emissions are rising: the most recent estimates put them at 21% above their Kyoto target over the first commitment period. These challenges are not insurmountable. New Zealand's energy policy is characterised by a commitment to free and open markets complimented by light-handed regulation. The IEA commends this approach and encourages continued policy improvements and enhancements. The energy policy review of New Zealand offers a comprehensive analysis of the country's energy sector, evaluating its strengths and weaknesses across the fuel mix, as well as looking at broader issues such as energy efficiency, environmental performance and technology research and development. It also includes policy critiques and recommendations, drawing on experience across IEA member countries. 33 figs., 21 tabs., 3 annexes.

The prepossession of international institutions for energy. The example International Energy Agency (IEA)

In the contribution under consideration, the author reports on the fact that large international energy agencies, which are advisory active in energy questions active, affect the world-wide policy. In particular, these are the International Atomic Energy Authority in Vienna (Austria) and the International Energy Agency in Paris (France). The International Energy Agency is considered world-wide as the most important institution for all energy questions. Nearly annually, it publishes the World Energy Outlook by summarizing the most important current energy data of the world, prognoses the future power supply and makes future energy prices. The reality of the International Energy Agency looks completely differently: It performs no own sciences, but consists of statisticians, who gather only statistical data without scientific analysis. The author of this contribution summarizes the work of the International Energy Agency in three points: (a) Promotion of the interests of companies in mineral oil, natural gas, coal and atomic energy; (b) Hindering the world-wide conversion of renewable energy; (c) Endangerment of the world economy and prevention of an effective climate protection. The International Energy Agency does not justice to its own goal of a reliable, economical and pollution free power supply

Since its inauguration in 1957, the IEA-R1 research reactor has been used mainly for research, development and teaching by scientific community. In the last years, with the increase of the commercial radiopharmaceutical production by Radiopharmacy Center of IPEN, the IEA-R1 reactor was recognized as a service supplier for that center and has received a treatment more commercial from IPEN Management. In 1999 the radiopharmaceutical production obtained the NBR ISO 9002 Certification, since that the IPEN Management considered convenient to invest in the certification of its internal suppliers. In this context, in 2001 the Research Reactor Center (CRPq) began the implantation of a Quality Management System (QMS) based on NBR 9001: 2000 standard, for activities related to the operation and maintenance of the IEA-R1 research reactor and irradiation services. This QMS was structured to incorporate tools already implemented in order to complain the requirements related to nuclear and radiological safe for a nuclear installation established by the regulatory organism. The QMS is supported by a documentation system composed of approximately 150 documents including quality manual, business and action plans, operational procedures and work instruction. Carlos Alberto Vanzolini Foundation (FCAV), an INMETRO certified organism, certified the 'Operation and Maintenance of the IEA-R1 Research Reactor and Irradiation Services' in December 2002. In 2003 and 2004, the QMS was audited by FCAV that determined the maintenance of the certification. This work presents the main steps of the QMS implementation, including the difficulties found and results obtained in the process. (author)

This report for the International Energy Agency (IEA) made by Task 9 of the Photovoltaic Power Systems (PVPS) programme takes a look at the implementation of Solar Home Systems in developing countries. The objective of Task 9 is to increase the successful deployment of PV systems in developing countries. This paper takes a look at financing mechanisms for Solar Home Systems (SHS). The lack of financial services for users of SHS is often regarded as the main barrier for their commercial dissemination and is often the justification for donor assisted programmes. This study attempts to shed some light on the question whether commercial SHS dissemination in remote rural areas could be made easier if financial services were made available. The authors state that the thesis is based on the fact that carefully designed, target-group-oriented financial services may speed up the widespread dissemination of SHS. Financial mechanisms for the stimulation of SHS and how their commercialisation can be achieved are among the topics discussed.

The IEA-R1 reactor of the Nuclear and Energy Research Institute (IPEN-CNEN/SP), is a research reactor open pool type, designed and built by the U.S. firm Babcock and Wilcox, having, as coolant and moderator, deionized light water and beryllium and graphite, as reflectors. Until about 1988, the reactor safety systems received power from only one source of energy. As an example, it may be cited the control desk that was powered only by the vital electrical system 220V, which, in case the electricity fails, is powered by the generator group: no-break 220V. In the years 1989 and 1990, a reform of the electrical system upgrading to increase the reactor power and, also, to meet the technical standards of the ABNT (Associacao Brasileira de Normas Tecnicas) was carried out. This work has the objective of showing the relationship between the electric power system and the IEA-R1 reactor security. Also, it demonstrates that, should some electrical power interruption occur, during the reactor operation, this occurrence would not start an accident event. (author)

This technology brief on gas-fired power is part of a series produced by the IEA called the energy technology data source (E-Tech-DS). The E-Tech-DS series consists of a number of 5-10 page technology briefs similar to the IEA Energy Technology Essentials. Based on the data collected for the models that the Energy Technology Systems Analysis Programme (ETSAP) is known for, ETSAP also prepares technology briefs, called E-TechDS. The E-TechDS briefs are standardized presentations of basic information (process, status, performance, costs, potential, and barriers) for key energy technology clusters. Each brief includes an overview of the technology, charts and graphs, and a summary data table, and usually ending with some key references and further information. The E TechDS briefs are intended to offer essential, reliable and quantitative information to energy analysts, experts, policymakers, investors and media from both developed and developing countries. This specific brief focuses on the state of combined-cycle gas turbines (CCGT). CCGT's have become the technology of choice for new gas-fired power plants since the 1990's.

Integrating global energy and climate governance: The changing role of the International Energy Agency

International Nuclear Information System (INIS)

Heubaum, Harald; Biermann, Frank

2015-01-01

Despite the long-recognized interlinkages between global energy consumption and climate change, there has historically been only limited policy interaction, let alone integration, between the two fields. This compartmentalization is mirrored in scholarship, where much research has focused on the fragmentation of, respectively, global energy and global climate governance, but only little has been said about how these fields might be integrated. Our analysis of the International Energy Agency’s (IEA) changing activities in recent years shows that governance integration – both within global energy governance and between global energy and climate governance – is now happening. The IEA has broadened its portfolio to embrace the full spectrum of energy issues, including renewable energy and climate change; it has built and is expanding key partnerships with both the UN climate convention and the International Renewable Energy Agency (IRENA); and it has become an authoritative advocate for the inter-related goals of a low-carbon transition and climate change mitigation. We show that these developments are not the result of a top-down plan, but have rather emerged through the Agency’s various efforts to pursue its energy-centric mandate in a fast-changing global policy environment. - Highlights: • Assesses integration between global energy and global climate governance. • Analyzes organizational change in the IEA and its impact on governance integration. • Discusses recent activities and advocacy by the IEA in relation to climate change.

Gruber, P.

2000-10-15

This report for the Swiss Federal Office of Energy (SFOE) discusses the results of tests made with two expert systems used for error-detection and diagnosis in existing buildings. These expert systems were developed within the framework of the International Energy Agency's (IEA) Annex 25 Project entitled 'Real Time Simulation of Heating, Ventilation and Air-conditioning (HVAC) Systems for Building Optimisation, Fault Detection and Diagnosis'. The aim of using these tools was to help detect planning, installation and commissioning errors. These cannot only affect system performance but also can cause increased energy consumption and a reduction of the working life of the system's components. The tests of the tools took place within the framework of the IEA's Annex 34 'Computer-aided Evaluation of HVAC System Performance: the Practical Application of Fault Detection and Diagnosis Techniques in Real Buildings'. Experience gained with the two tools is presented and discussed. The quality of the results and the use of the systems in practice are discussed and commented on. They strongly differ from one tool to the other.

In this paper the main features of the reliability database being developed at Ipen-Cnen/SP for IEA-R1 reactor are briefly described. Besides that, the process for collection and updating of data regarding operation, failure and maintenance of IEA-R1 reactor components is presented. These activities have been conducted by the reactor personnel under the supervision of specialists in Probabilistic Safety Analysis (PSA). The compilation of data and subsequent calculation are based on the procedures defined during an IAEA Coordinated Research Project which Brazil took part in the period from 2001 to 2004. In addition to component reliability data, the database stores data on accident initiating events and human errors. Furthermore, this work discusses the experience acquired through the development of the reliability database covering aspects like improvements in the reactor records as well as the application of the results to the optimization of operation and maintenance procedures and to the PSA carried out for IEA-R1 reactor.

Innovation in the energy sector: Lessons learnt from R and D expenditures and patents in selected IEA countries

International Nuclear Information System (INIS)

Bointner, Raphael

2014-01-01

Long time series of the IEA and international patent offices offer a huge potential for scientific investigations of the energy innovation process. Thus, this paper deals with a broad literature review on innovation drivers and barriers, and an analysis of the knowledge induced by public research and development expenditures (R and D) and patents in the energy sector. The cumulative knowledge stock induced by public R and D expenditures in 14 investigated IEA-countries is 102.3 bn EUR in 2013. Nuclear energy has the largest share of 43.9 bn EUR, followed by energy efficiency accounting for 14.9 bn EUR, fossil fuels with 13.5 bn EUR, and renewable energy with 12.1 bn EUR. A regression analysis indicates a linear relation between the GDP and the cumulative knowledge, with each billion EUR of GDP leading to an additional knowledge of 3.1 mil EUR. However, linearity is not given for single energy technologies. Further, the results show that appropriate public R and D funding for research and development associated with a subsequent promotion of the market diffusion of a niche technology may lead to a breakthrough of the respective technology. - Highlights: • The cumulative energy knowledge stock in 14 IEA-countries is 102.3 bn EUR in 2013. • Each billion EUR of GDP lead to an additional knowledge of 3.1 mil EUR. • Medium IEA-countries may compete with large ones by promoting a niche strategy. • Patent knowledge grew 5.9 times in medium and 5.6 in large IEA-countries since 1990

This work introduces the Diagram of Emergency Exercise Coordination designed by the Nuclear Safety Team for better Emergency Exercise coordination. The Nuclear Safety Team was created with the mission of avoiding, preventing and mitigating the causes and effects of accidents at the IEA-R1. The facility where we conduct our work is located in an area of a huge population, what increases the responsibility of our mission: conducting exercises and training are part of our daily activities. During the Emergency Exercise, accidents ranked 0-4 on INES (International Nuclear Events Scale) are simulated and involve: Police Department, Fire Department, workers, people from the community, and others. In the last exercise held in June 2014, the scenario contemplated a terrorist organization action that infiltrated in a group of students who were visiting the IEA-R1, tried to steal fresh fuel element to fabricate a dirty bomb. Emergency procedures and plans, timeline and metrics of the actions were applied to the Emergency Exercise evaluation. The next exercise will be held in November, with the simulation of the piping of the primary cooling circuit rupture, causing the emptying of the pool and the lack of cooling of the fuel elements in the reactor core: this will be the scenario. The skills acquired and the systems improvement have been very important tools for the reactor operation safety and the Nuclear Safety Team is making technical efforts so that these Emergency Exercises may be applied to other nuclear and radiological facilities. Equally important for the process of improving nuclear safety is the emphasis placed on implementing quality improvements to the human factor in the nuclear safety area, a crucial element that is often not considered by those outside the nuclear sector. Surely, the Diagram of Emergency Exercise Coordination application will improve and facilitate the organization, coordination and evaluation tasks. (author)

Technology status of hydrogen road vehicles. IEA technical report from the IEA Agreement of the production and utilization of hydrogen

Energy Technology Data Exchange (ETDEWEB)

Doyle, T.A.

1998-01-31

The report was commissioned under the Hydrogen Implementing Agreement of the International Energy Agency (IEA) and examines the state of the art in the evolving field of hydrogen-fueled vehicles for road transport. The first phase surveys and analyzes developments since 1989, when a comprehensive review was last published. The report emphasizes the following: problems, especially backfiring, with internal combustion engines (ICEs); operational safety; hydrogen handling and on-board storage; and ongoing demonstration projects. Hydrogen vehicles are receiving much attention, especially at the research and development level. However, there has been a steady move during the past 5 years toward integral demonstrations of operable vehicles intended for public roads. Because they emit few, or no greenhouse gases, hydrogen vehicles are beginning to be taken seriously as a promising solution to the problems of urban air quality. Since the time the first draft of the report was prepared (mid-19 96), the 11th World Hydrogen Energy Conference took place in Stuttgart, Germany. This biennial conference can be regarded as a valid updating of the state of the art; therefore, the 1996 results are included in the current version. Sections of the report include: hydrogen production and distribution to urban users; on-board storage and refilling; vehicle power units and drives, and four appendices titled: 'Safety questions of hydrogen storage and use in vehicles', 'Performance of hydrogen fuel in internal production engines for road vehicles, 'Fuel cells for hydrogen vehicles', and 'Summaries of papers on hydrogen vehicles'.

Every year Policy of IEA Countries includes a forecast of the energy consumption in the member countries. Forecasts concerning the years 1985,1990 and 1995 can now be compared to actual values. The second oil crisis resulted in big positive forecast errors. The oil price drop in 1986 did not have...... the small value is often the sum of large positive and negative errors. Almost no significant correlation is found between forecast errors in the 3 years. Correspondingly, no significant correlation coefficient is found between forecasts errors in the 3 main energy sectors. Therefore, a relatively small...

The dispatch and load duration curve of the interconnected electrical system, in the hypothetical context of the 450ppm scenario of the Iea; El despacho y la curva de duracion de carga del sistema electrico interconectado, en el contexto hipotetico del escenario 450 ppm de la IEA

The concept of the annual load duration curve of the national interconnected system is presented, which by means of a quadrature procedure becomes a 3-block diagram: one for the base load that occurs at 8,760 hours of the year; another for intermediate load, above the minimum that occurs in a variable number of hours of the year, and another for the peak demand that only happens a few hours of the year. The data of the table of capacity and generation of electric power in 2014, according to Annex A of the Mexico Energy Outlook document of the International Energy Agency (Iea), are converted into a block diagram adjusted to the annual curve of load duration of that year. The procedure is repeated with the capacity and electric power generation data projected by the Iea at 2030 and 2040, according to the 450ppm scenario, which is considered necessary to stabilize the concentration of CO{sub 2} in the atmosphere at 450 parts per million and ensure that the increase in the global temperature of the planet does not exceed 2 degrees Celsius, compared to pre-industrial levels. Then, the same capacity and generation data projected by the Iea by 2040 are tabulated by technology type, grouped now within the base, intermediate and peak blocks of the annual load duration curve for that year, and ordered from according to its plant factor, indicative of its availability to be dispatched. The above, in order to estimate the aggregate result of the annual dispatch that could be made by CENACE, if the projections of electric power generation to the year 2040 foreseen in the ambitious 450ppm scenario were given. Finally, an exercise is carried out to estimate, at 2015 prices, the unit costs of technologies generation in the year 2040, expressed in US D (2015)/ MWh and broken down into fixed and variable reference costs.

2010-05-15

This technology brief on conventional oil and gas technologies is part of a series produced by the IEA ETSAP agreement called the energy technology data source (E-Tech-DS). The E-Tech-DS series consists of a number of 5-10 page technology briefs similar to the IEA Energy Technology Essentials. Based on the data collected for the models that the Energy Technology Systems Analysis Programme (ETSAP) is known for, ETSAP also prepares technology briefs, called E-TechDS. The E-TechDS briefs are standardized presentations of basic information (process, status, performance, costs, potential, and barriers) for key energy technology clusters. Each brief includes an overview of the technology, charts and graphs, and a summary data table, and usually ending with some key references and further information. The E TechDS briefs are intended to offer essential, reliable and quantitative information to energy analysts, experts, policymakers, investors and media from both developed and developing countries. This specific brief focuses on the state of oil and gas exploration, development, and production/recovery technologies.

IEA HPP Annex 29 - ground-source heat pumps overcoming technical and market barriers. Status report Norway

2004-12-01

Norway is a member of Annex 29, 'Ground-Source Heat Pump Systems Overcoming Technical and Market Barriers' (2004-2006), organized under the umbrella of the International Energy Agency (IEA) and the IEA Heat Pump Programme (HPP). The 7 participating countries are Austria (Operating Agent), Canada, Japan, Norway, Spain, Sweden and the USA. The Norwegian participation is financed by ENOVA SF, and SINTEF Energy Research is responsible for planning and carrying out the Norwegian activities. This report provides a status for ground-source heat pump (GSHP) systems in Norway with regard to state-of-the-art technology, installation examples, geological data, costs and market opportunities. A Norwegian Internet home page for ground-source heat pump systems (www.energy.sintef.no/prosjekt/Annex29) is also presented. GSHP systems in Norway are classified as direct systems (groundwater and soil/ground) and indirect closed-loop systems (vertical-rock and horizontal-soil/ground). The vast majority of the installations are indirect closed-loop systems utilizing vertical boreholes in rock as a heat source, heat sink and thermal energy storage. GSHP systems are relatively capital intensive installations, but they achieve high energy efficiency due to the relatively high and stable heat source temperature and the fact that a considerable share of the cooling demand in non-residential buildings can be covered by means of free cooling. In order to obtain energy efficient and reliable GSHP installations, it is important to implement a total quality concept where focus is on quality and system integration during all stages of the project. A life cycle analysis (LCA) will be an important tool in such a concept, since both the investment costs as well as the lifetime operational and maintenance costs are included (author) (ml) Litt usikker pae tag 620- ikke en vanlig sintef rapportkode

Characterization of filters cartridges from the water polishing system of IEA-R1 reactor: radiometric methods

International Nuclear Information System (INIS)

Tessaro, Ana Paula G.; Vicente, Roberto

2015-01-01

The acceptance of radioactive waste in a repository depends primarily on knowledge of the radioisotopic inventory of the material, according to regulations established by regulatory agencies. The primary characterization is also a fundamental action to determine further steps in the management of the radioactive wastes. The aim of this work is to report the development of non-destructive methods for primary characterization of filters cartridges discarded as radioactive waste. The filters cartridges are used in the water polishing system of the IEA-R1 reactor retaining the particles in suspension in the reactor cooling water. The IEA-R1 is a pool type reactor with a thermal power of 5 MW, moderated and cooled with light water. It is located in the Energy and Nuclear Research Institute (IPEN-CNEN), in São Paulo, Brazil. The cartridge filters become radioactive waste when they are saturated and do not meet the required flow for the proper operation of the water polishing system. The activities of gamma emitters present in the filters are determined using gamma spectrometry, dose rate measurements and the Point Kernel Method to correlate results from both measurements. For the primary characterization, one alternative method is the radiochemical analysis of slices taken from each filter, what presents the disadvantage of higher exposures personnel and contamination risks. Another alternative method is the calibration of the measurement geometry of a gamma spectrometer, which requires the production of a standard filter. Both methods are necessary but can not be used in operational routine of radioactive waste management owing to cost and complexity. The method described can be used to determine routinely the radioactive inventory of these filters and other radioactive wastes, avoiding the necessity of destructive radiochemical analysis, or the necessity of calibrating the geometry of measurement.

The dispatch and load duration curve of the interconnected electrical system, in the hypothetical context of the 450ppm scenario of the Iea

International Nuclear Information System (INIS)

Villanueva M, C.

2017-09-01

The concept of the annual load duration curve of the national interconnected system is presented, which by means of a quadrature procedure becomes a 3-block diagram: one for the base load that occurs at 8,760 hours of the year; another for intermediate load, above the minimum that occurs in a variable number of hours of the year, and another for the peak demand that only happens a few hours of the year. The data of the table of capacity and generation of electric power in 2014, according to Annex A of the Mexico Energy Outlook document of the International Energy Agency (Iea), are converted into a block diagram adjusted to the annual curve of load duration of that year. The procedure is repeated with the capacity and electric power generation data projected by the Iea at 2030 and 2040, according to the 450ppm scenario, which is considered necessary to stabilize the concentration of CO 2 in the atmosphere at 450 parts per million and ensure that the increase in the global temperature of the planet does not exceed 2 degrees Celsius, compared to pre-industrial levels. Then, the same capacity and generation data projected by the Iea by 2040 are tabulated by technology type, grouped now within the base, intermediate and peak blocks of the annual load duration curve for that year, and ordered from according to its plant factor, indicative of its availability to be dispatched. The above, in order to estimate the aggregate result of the annual dispatch that could be made by CENACE, if the projections of electric power generation to the year 2040 foreseen in the ambitious 450ppm scenario were given. Finally, an exercise is carried out to estimate, at 2015 prices, the unit costs of technologies generation in the year 2040, expressed in US D (2015)/ MWh and broken down into fixed and variable reference costs.

2008-12-15

An important part of the cooperation within the IEA (International Energy Agency) is organised through national contributions to 'Implementation Agreements' on energy technology and energy analyses. One of them is ETSAP (Energy Technology Systems Analysis Programme), started in 1976. Denmark has signed the agreement and contributed to some early annexes. This project is motivated by an invitation to participate in ETSAP Annex X, 'Global Energy Systems and Common Analyses: Climate friendly, Secure and Productive Energy Systems' for the period 2005 to 2007. The main activity is semi-annual workshops focusing on presentations of model analyses and use of the ETSAP tools (the MARKAL/TIMES family of models). The project was also planned to benefit from the EU project 'NEEDS - New Energy Externalities Developments for Sustainability'. ETSAP is contributing to a part of NEEDS that develops the TIMES model for 29 European countries with assessment of future technologies. An additional project 'Monitoring and Evaluation of the RES directives: implementation in EU27 and policy recommendations for 2020' (RES2020) under Intelligent Energy Europe was added, as well as the Danish 'Centre for Energy, Environment and Health (CEEH), starting from January 2007. This report summarises the activities under ETSAP Annex X and related project, emphasising the development of modelling tools that will be useful for modelling the Danish energy system. It is also a status report for the development of a model for Denmark, focusing on the tools and features that allow comparison with other countries and, particularly, to evaluate assumptions and results in international models covering Denmark.

Offshore wind turbines are designed and analyzed using comprehensive simulation codes that account for the coupled dynamics of the wind inflow, aerodynamics, elasticity, and controls of the turbine, along with the incident waves, sea current, hydrodynamics, and foundation dynamics of the support structure. This paper describes the latest findings of the code-to-code verification activities of the Offshore Code Comparison Collaboration, which operates under Subtask 2 of the International Energy Agency Wind Task 23. In the latest phase of the project, participants used an assortment of codes to model the coupled dynamic response of a 5-MW wind turbine installed on a floating spar buoy in 320 m of water. Code predictions were compared from load-case simulations selected to test different model features. The comparisons have resulted in a greater understanding of offshore floating wind turbine dynamics and modeling techniques, and better knowledge of the validity of various approximations. The lessons learned from this exercise have improved the participants' codes, thus improving the standard of offshore wind turbine modeling.

IEA-R1 primary and secondary coolant piping systems coupled stress analysis

Fainer, Gerson; Faloppa, Altair A.; Oliveira, Carlos A.; Mattar Neto, Miguel

2013-01-01

The aim of this work is to perform the stress analysis of a coupled primary and secondary piping system of the IEA-R1 based on tridimensional model, taking into account the as built conditions. The nuclear research reactor IEA-R1 is a pool type reactor projected by Babcox-Willcox, which is operated by IPEN since 1957. The operation to 5 MW power limit was only possible after the conduction of life management and modernization programs in the last two decades. In these programs the components of the coolant systems, which are responsible for the water circulation into the reactor core to remove the heat generated inside it, were almost totally refurbished. The changes in the primary and secondary systems, mainly the replacement of pump and heat-exchanger, implied in piping layout modifications, and, therefore, the stress condition of the piping systems had to be reanalyzed. In this paper the structural stress assessment of the coupled primary and secondary piping systems is presented and the final results are discussed. (author)

The need for combining IEA and IE tools. The potential effects of a global ban on PVC on climate change

International Nuclear Information System (INIS)

Kleijn, Rene; Van der Voet, Ester; Udo de Haes, Helias A.

2008-01-01

Over the last decades the concepts of Integrated Environmental Assessment (IEA) and Industrial Ecology (IE), both claiming to provide analyses and solutions for sustainability issues, have been developed separately as they emerged in response to questions from different policy-fields. In both fields, specific tools are used to support national and international environmental policy. The focus of IEA and IE tools, however, is different. IEA tools focus on one or a limited number of specific environmental issues. They often model the chain environmental processes with high spatial (and temporal) resolution, but have a low resolution for the material structure of the economy and only partly take into account indirect effects that occur via physical and socio-economic linkages. IE tools take into account all environmental issues related to a specific substance or product. They have a high resolution for the material structure of the economy and take into account indirect effects that occur via physical linkages, however, their environmental modelling is very limited. Both IE and IEA tools have proven to be very useful and neither is superior to the other. However, a combination of both can provide additional information that can be used for more effective policy making. We use the case of a hypothetical world-wide ban on PVC to show that a measure that is not directly related to climate change could still have significant climate effects. This indirect effect is a result of the linkages of material flows in society. We show that IEA tools are not well suited to include these types of effects and that IE tools can fill this gap partially. What is really needed is a broader systems perspective that takes into account the full range of possible side-effects of environmental policy measures. (author)

Future oil supply: The changing stance of the International Energy Agency

International Nuclear Information System (INIS)

Miller, Richard G.

2011-01-01

The IEA was established in 1974 with a mandate to promote energy security amongst its members, namely the states of the OECD, and to advise those members on sound energy policy. Its recent forecasts of the medium and long term prospects for oil supply, however, have wavered, alternating from optimistic to pessimistic and back again. For policy-makers, such inconsistency is difficult to deal with. Firstly we examine whether the changing outlooks seen in IEA forecasts made between 2007 and 2010 truly reflect a demonstrable, underlying change in the known facts, and we can find no such factual changes reported by the IEA. Secondly we examine whether the serious criticisms of the forecast made by other analysts have yet been addressed, and we conclude that they have not. Thirdly we consider the possible effects of the current economic downturn upon the IEA's assumptions and upon future oil supply. We conclude that all the forecasts made by the IEA appear to be too optimistic throughout this period. - Research highlights: → IEA forecasts of oil supply have changed from optimistic to pessimistic and back. → The reasons for the changes are listed, examined and found wanting. → The most appropriate IEA forecast is nevertheless the most pessimistic one. → Some criticisms of the forecast methodology and assumptions are described.

Characterization of the water filters cartridges from the iea-r1 reactor using the Monte Carlo method

International Nuclear Information System (INIS)

Costa, Priscila; Potiens Junior, Ademar J.

2015-01-01

Filter cartridges are part of the primary water treatment system of the IEA-R1 Research Reactor and, when saturated, they are replaced and become radioactive waste. The IEA-R1 is located at the Nuclear and Energy Research Institute (IPEN), in Sao Paulo, Brazil. The primary characterization is the main step of the radioactive waste management in which the physical, chemical and radiological properties are determined. It is a very important step because the information obtained in this moment enables the choice of the appropriate management process and the definition of final disposal options. In this paper, it is presented a non-destructive method for primary characterization, using the Monte Carlo method associated with the gamma spectrometry. Gamma spectrometry allows the identification of radionuclides and their activity values. The detection efficiency is an important parameter, which is related to the photon energy, detector geometry and the matrix of the sample to be analyzed. Due to the difficult to obtain a standard source with the same geometry of the filter cartridge, another technique is necessary to calibrate the detector. The technique described in this paper uses the Monte Carlo method for primary characterization of the IEA-R1 filter cartridges. (author)

Energy Policies of IEA Countries: European Union 2008 Review

Energy Technology Data Exchange (ETDEWEB)

2008-07-01

For the first time, the IEA has reviewed the energy policies of the European Union which shape the energy use of almost 500 million citizens in 27 EU member countries. A unique entity governed under complex and almost constantly evolving structures, the EU constitutes a challenge for energy policy makers. Its energy policy has a global impact, not only because of its 16% share of world energy demand, but also because of the EU leadership in addressing climate change. Strong policy drives are underway in the EU to achieve the completion of the internal energy market, increase renewable energy supply, reduce CO2 emissions and make the EU more energy-efficient. Concerns about security of supply have also led to a greater focus on improved energy relations with supplier countries, and new institutional structures are being put in place. How much progress has been made in the field of security, internal market and external energy policies? And in which of these areas has the EU already implemented a fully integrated policy? IEA Energy Policies Review: The European Union - 2008 addresses these questions and also analyses the impact of the most recent major EU policy measures, in particular the Energy & Climate Package of January 2008 and the 3rd Liberalisation Package of September 2007. This book finds that both of these proposals are highly ambitious. But implementing them and reviewing both volume and allocation of energy R&D will be necessary to achieve a sustainable energy future in a fully competitive integrated EU energy market.

Estimating the impacts of wind power on power systems—summary of IEA Wind collaboration

Adding wind power to power systems will have beneficial impacts by reducing the emissions of electricity production and reducing the operational costs of the power system as less fuel is consumed in conventional power plants. Wind power will also have a capacity value to a power system. However, possible negative impacts will have to be assessed to make sure that they will only offset a small part of the benefits and also to ensure the security of the power system operation. An international forum for the exchange of knowledge of power system impacts of wind power has been formed under the IEA Implementing Agreement on Wind Energy. The Task 'Design and Operation of Power Systems with Large Amounts of Wind Power' is analyzing existing case studies from different power systems. There are a multitude of studies completed and ongoing related to the cost of wind integration. However, the results are not easy to compare. This paper describes the general issues of wind power impacts on power systems and presents a comparison of results from ten case studies on increased balancing needs due to wind power.

Mello, Jose Roberto de; Madi Filho, Tufic

2015-01-01

The IEA-R1 research reactor at the Institute of Energy and Nuclear Research (IPEN) is a research reactor open pool type, built and designed by the American firm 'Babcox and Wilcox', having as coolant and moderator demineralized light water and Beryllium and graphite, as reflectors. The power supply system is designed to meet the electricity demand required by the loads of the reactor (Security systems and systems not related to security) in different situations the plant can meet, such as during startup, normal operation at power, shutdown, maintenance, exchange of fuel elements and accident situations. Studies have been done on possible accident initiating events and deterministic techniques were applied to assess the consequences of such incidents. Thus, the methods used to identify and select the accident initiating events, the methods of analysis of accidents, including sequence of events, transient analysis and radiological consequences, have been described. Finally, acceptance criteria of radiological doses are described. Only a brief summary of the item concerning loss of electrical power will be presented. The loss of normal electrical power at the IEA-R1 reactor is very common. In the case of Electric External Power Loss, at the IEA-R1 reactor building, there may be different sequences of events, as described below. When the supply of external energy in the IEA-R1 facility fails, the Electrical Distribution Vital System, consisting of 4 (four) generators type 'UPS', starts operation, immediately and it will continue supplying power to the reactor control table, core cooling system and other security systems. To contribute to security, in the electric power failure, starts to operate the Emergency Cooling System (SRE). SRE has the function of removing residual heat from the core to prevent the melting of fuel elements in the event of loss of refrigerant to the core. Adding to the generators with batteries group system, new auxiliary

This second part of a report for the International Energy Agency (IEA) made by Task 9 of the Photovoltaic Power Systems (PVPS) programme takes a look at the implementation of Solar Home Systems in developing countries. The objective of Task 9 is to increase the successful deployment of PV systems in developing countries. This summary outlines various models for the implementation of small domestic photovoltaic (PV) systems (Solar Home Systems, SHS) in developing countries. The first part of this two-part document discussed three generic models. Part 2 of the document is based on work prepared for the Renewable Energy Supply Models (RESUM) project. Examples are quoted which describe the operations of a number of companies supplying solar home systems in developing countries. These examples of practical experience provide a description of businesses, highlighting the success and failure factors of the organisations. They are only a sample of the many PV companies operating internationally and are not to be considered as a critical evaluation of the implementation models; they attempt to give the reader an idea of the realities of using the models in practice.

This report for the International Energy Agency (IEA) made by Task 9 of the Photovoltaic Power Systems (PVPS) programme takes a look at the role of quality management, hardware certification and accredited training in PV programmes in developing countries. The objective of this document is to provide assistance to those project developers that are interested in implementing or improving support programmes for the deployment of PV systems for rural electrification. It is to enable them to address and implement quality assurance measures, with an emphasis on management, technical and training issues and other factors that should be considered for the sustainable implementation of rural electrification programmes. It is considered important that quality also addresses the socio-economic and the socio-technical aspects of a programme concept. The authors summarise that, for a PV programme, there are three important areas of quality control to be implemented: quality management, technical standards and quality of training.

Various measures were implemented with the aim of realizing the 'longterm vision for international cooperation' in connection with hydrogen utilization international clean energy system technology (WE-NET) formulated in fiscal 1996. The English version of the 1998 annual summary report on results was distributed to approximately 170 pertinent organizations overseas. To develop understanding of the WE-NET project, presentations were given in numerous international conferences. In addition, as research cooperation in IEA (International Energy Agency), specialists were dispatched to the hydrogen implementation committee, the corresponding committee to hydrogen implementation agreement, and to each annex. In international exchange of technical information, each WE-NET task exchanged information with organizations abroad through overseas survey and conducted research on European hydrogen project, for example. With the purpose of developing understanding of WE-NET project activities, a preparatory work was done for participation in HYFORUM2000 (Germany) and World Hydrogen Energy Conference (Beijing) which will be held in 2000.

Development of a training simulator to operators of the IEA-R1 research reactor

International Nuclear Information System (INIS)

Carvalho, Ricardo Pinto de

2006-01-01

This work reports the development of a Simulator for the IEA-R1 Research Reactor. The Simulator was developed with Visual C++ in two stages: construction of the mathematics models and development and configuration of graphics interfaces in a Windows XP executable. A simplified modeling was used for main physics phenomena, using a point kinetics model for the nuclear process and the energy and mass conservation laws in the average channel of the reactor for the thermal hydraulic process. The dynamics differential equations were solved by using finite differences through the 4th order Runge- Kutta method. The reactivity control, reactor cooling, and reactor protection systems were also modeled. The process variables are stored in ASCII files. The Simulator allows navigating by screens of the systems and monitoring tendencies of the operational transients, being an interactive tool for teaching and training of IEA-R1 operators. It also can be used by students, professors, and researchers in teaching activities in reactor and thermal hydraulics theory. The Simulator allows simulations of operations of start up, power maneuver, and shut down. (author)

IEA-R1 research reactor: operational life extension and considerations regarding future decommissioning

International Nuclear Information System (INIS)

Frajndlich, Roberto

2009-01-01

The IEA-R1 reactor is a pool type research reactor moderated and cooled by light water and uses graphite and beryllium reflectors. The reactor is located at the Instituto de Pesquisas Energeticas e Nucleares (IPEN-CNEN/SP), in the city of Sao Paulo, Brazil. It is the oldest research reactor in the southern hemisphere and one of the oldest of this kind in the world. The first criticality of the reactor was obtained on September 16, 1957. Given the fact that Brazil does not have yet a definitive radioactive waste repository and a national policy establishing rules for the spent fuel storage, the institutions which operate the research reactors for more than 50 years in the country have searched internal solutions for continued operation. This paper describes the spent fuel assemblies and radioactive waste management process for the IEA-R1 reactor and the refurbishment and modernization program adopted to extend its lifetime. Some considerations about the future decommissioning of the reactor are also discussed which, in my opinion, might help the operating organization to make decisions about financial, legal and technical aspects of the decommissioning procedures in a time frame of 10-15 years(author)

2002-02-15

This report for the International Energy Agency (IEA) made by Task 5 of the Photovoltaic Power Systems (PVPS) programme takes a look at the power value and capacity value of photovoltaic power systems. The mission of the Photovoltaic Power Systems Programme is to enhance the international collaboration efforts which accelerate the development and deployment of photovoltaic solar energy. Task 5 deals with issues concerning grid-interconnection and dispersed PV power systems. This report summarises the results of a study aimed to assess the benefits that may be obtained when distributed PV production systems are present in a low-voltage grid. The basic aspects concerning the power-value and those related to the capacity-value are discussed. Data obtained from simulations are presented and discussed. A simple concept shows that great variation occurs if varying load patterns are taken into account. The power-value of PV generation in the grid varies instant by instant depending on the current level of power production and on the surrounding load conditions. Although the three case-studies considered do not cover all the possibilities of coupling between PV and loads, the results obtained show a good differentiation among users with PV production which leads to interesting conclusions.

The IEA-R1 reactor of IPEN/CNEN-SP in Brazil is a pool type research reactor cooled and moderated by demineralized water and having Beryllium and Graphite as reflectors. In 1997 the reactor received the operating licensing for 5 MW. A new research reactor is being planned in Brazil to replace the IEA-R1 reactor. This new reactor, the Brazilian Multipurpose Reactor (RMB), planned for 30 MW, is now in the conception design phase. Low enriched uranium (LEU) (<20% {sup 235}U) UAl{sub x} dispersed in Al targets are being considered for production of Molybdenum-99 ({sup 99}Mo) by fission. Neutronic and thermal-hydraulics calculations were performed, respectively, to compare the production of {sup 99}Mo for these targets in IEA-R1 reactor and RMB and to determine the temperatures achieved in the UAl{sub x}-Al targets during irradiation. For the neutronic calculations were utilized the computer codes HAMMER-TECHNION, CITATION and SCALE and for the thermal-hydraulics calculations was utilized the computer code MTRCR-IEAR1. (author)

This first part of a two-part report for the International Energy Agency (IEA) made by Task 9 of the Photovoltaic Power Systems (PVPS) programme takes a look at the implementation of Solar Home systems in developing countries. The objective of Task 9 is to increase the successful deployment of PV systems in developing countries. This summary outlines various models for the implementation of small domestic photovoltaic (PV) systems (Solar Home Systems, SHS) in developing countries. Part 1 of this two-part document discusses three generic models. The second, separate part of the document provides a number of examples demonstrating the models described. This report focuses on the implementation of SHS. However, a considerable amount of the PV market in developing countries is stated as consisting of large systems providing electricity for social services, such as light for schools, mosques, churches, communal centres, refrigeration for health centres and drinking water for communities. It is noted that there are considerable differences between the 'social market' and the 'private market' for SHS. The 'social market' generally consists of large systems but fewer in number. The guide does not cover the detailed technical aspects of a Solar Home System or the issue of recycling old batteries.

Application of nondestructive methods for qualification of high density fuels in the IEA-R1 reactor

International Nuclear Information System (INIS)

Silva, Jose E.R.; Silva, Antonio T.; Domingos, Douglas B.; Terremoto, Luis A.A.

2011-01-01

IPEN/CNEN-SP manufactures fuels to be used in its research reactor - the IEA-R1. To qualify those fuels, it is necessary to check if they have a good performance under irradiation. As Brazil still does not have nuclear research reactors with high neutron fluxes, or suitable hot cells for carrying out post-irradiation examination of nuclear fuels, IPEN/CNEN-SP has conducted a fuel qualification program based on the use of uranium compounds (U 3 O 8 and U 3 Si 2 dispersed in Al matrix) internationally tested and qualified to be used in research reactors, and has attained experience in the technological development stages for the manufacturing of fuel plates, irradiation and non-destructive post-irradiation testing. Fuel elements containing low volume fractions of fuel in the dispersion were manufactured and irradiated successfully directly in the core of the IEA-R1. However, there are plans at IPEN/CNEN-SP to increase the uranium density of the fuels. Ten fuel miniplates (five containing U 3 O 8 -Al and five containing U 3 Si 2 -Al), with densities of 3.2 gU/cm 3 and 4.8 gU/cm 3 respectively, are being irradiated inside an irradiation device placed in a peripheral position of the IEA-R1 core. Non-destructive methods will be used to evaluate irradiation performance of the fuel miniplates after successive cycles of irradiation, by means: monitoring the reactor parameters during operation; periodic underwater visual inspection of fuel miniplates, eventual sipping test for fuel miniplates suspected of leakage and underwater measuring of the miniplate thickness for assessment of the fuel miniplate swelling.

IEA-R1 research reactor at the Instituto de Pesquisas Energeticas e Nucleares (Nuclear and Energy Research Institute) IPEN, Sao Paulo, Brazil is the largest power research reactor in Brazil, with a maximum power rating of 5 MWth. It is being used for basic and applied research in the nuclear and neutron related sciences, for the production of radioisotopes for medical and industrial applications, and for providing services of neutron activation analysis, real time neutron radiography, and neutron transmutation doping of silicon. IEA-R1 is a swimming pool reactor, with light water as the coolant and moderator, and graphite and beryllium as reflectors. The reactor was commissioned on September 16, 1957 and achieved its first criticality. It is currently operating at 4.5 MWth with a 60-hour cycle per week. In the early sixties, IPEN produced {sup 131}I, {sup 32}P, {sup 198}Au, {sup 24}Na, {sup 35}S, {sup 51}Cr and labeled compounds for medical use. During the past several years, a concerted effort has been made in order to upgrade the reactor power to 5 MWth through refurbishment and modernization programs. One of the reasons for this decision was to produce {sup 99}Mo at IPEN. The reactor cycle will be gradually increased to 120 hours per week continuous operation. It is anticipated that these programs will assure the safe and sustainable operation of the IEA-R1 reactor for several more years, to produce important primary radioisotopes {sup 99}Mo, {sup 125}I, {sup 131}I, {sup 153}Sm and {sup 192}Ir. Currently, all aspects of dealing with fuel element fabrication, fuel transportation, isotope processing, and spent fuel storage are handled by IPEN at the site. The reactor modernization program is slated for completion by 2015. This paper describes 58 years of operating experience and utilization of the IEA-R1 research reactor for research, teaching and radioisotopes production. (authors)

Pneumatic Transfer Systems (PTS) are classified as mechanical equipment largely operated all over the world for transport of a huge sort of objects, samples and materials located at nearly terminals or even at separated ones. System applicability is often recognized in many activities, such as medicine (hospital settings, clinical analysis labs), industry (steel, automobiles, mining, chemical, food, construction), trading (gas station, movies, supermarkets, banks, e-commerce) and federal agencies (post services, federal courts, public enterprises). In the nuclear settings, PTS shows also a vast array of applications, being a part of radioisotope production, as well as short-lived radiopharmaceuticals, including 67 Ga, 201 Tl, 18 F and 123 I-ultra pure. Besides, PTS are also used at radioactive waste management plants and research institutes that apply neutron activation analysis (NAA). This work was directed toward the design and operation of a new PTS for the IEA-R1 nuclear research reactor settled at Instituto de Pesquisas Energeticas e Nucleares (IPEN) for NAA application. With this aim, it was calculated the charge of reactor core grid plate and sample transport testing. Neutron flux at irradiating position was determined as 3,70 {+-} 0,26 10{sup 12} n cm{sup -2} s{sup -1}. (author)

Measurements and calculation of reactivity in the IEA-R1 nuclear reactor

International Nuclear Information System (INIS)

Ferreira, P.S.B.

1988-01-01

Techniques and experimentals procedures utilized in the measurement of some nuclear parameters related to reactivity are presented. Measurements of reactivity coefficients, such as void, temperature and power, and control rod worth were made in the IEA-R1 Research Reactor. The techniques used to perform the measurements were: i) stable period (control rod calibration), ii) inverse kinetics (digital reactivity meter), iii) aluminium slab insertion in the fuel element coolant channels (void reactivity), iv) nuclear reactor core temperature changes by means of the changes in the coolant systems of reactor core (isothermal reactivity coefficient) and v) by making perturbation in the core through the control rod motions (power reactivity coefficient and control rod calibration). By using the computer codes HAMMER, HAMMER-TECHNION and CITATION, the experiments realized in the IEA-R1 reactor were simulated. From this simulation, the theoretical reactivity parameters were estimated and compared with the respective experimental results. Furthermore, in the second fuel load of Angra-1 Nuclear Power Station, the IPEN-CNEN/SP digital reactivity - meter were used in the lower power test with the aim to assess the equipment performance. Among several tests, the reacticity-meter were used in parallel with a Westinghouse analogic reativimeter-meter) to measure the heat additiona point, critical boron concentration, control rod calibration, isothermal and moderator reactivity coefficient. These tests, and the results obtained by the digital reactivity-meter are described. The results were compared with those obtained by Westinghouse analogic reactivity meter, showing excellent agreement. (author) [pt

1978-01-01

With the purpose to check the performance of IEA Triple Axis Spectrometer of which construction was recently finished, dispersion relation curves for copper at room temperature have been messured. The frequencies of phonons propagating along the three major simmetry directions [xi00] [xixi0] and [xixixi] have been determined. The measurements were carried out operating the Triple Axis Spectrometer in the 'Q constant' mode at neutron energy loss. An excellent agreement could be observed between the results obtained in the present experiment and the accurate data for copper presented in the litterature. In such way, we can conclude that the IEA Triple Axis Spectrometer is in good operational conditions and able to perform original experiments. In this report an outline of the theory of the spectrometer operation and details on the experimental procedures for the case of a Triple Axis Spectrometer operating in the 'Q constant' mode are also presented [pt

Combined photovoltaic and solar-thermal systems: overcoming barriers to market acceptance. Paper no. IGEC-1-136

International Nuclear Information System (INIS)

Collins, M.R.

2005-01-01

In 1997, the International Energy Association's (IEA) Photovoltaic Power Systems Program (PVSP) initiated IEA Task 7 to evaluate the technical status of combined Photovoltaic and Solar-Thermal systems (PV/T), and to formulate a roadmap for future development. Because the Task was initiated by the PVSP, however, individuals from the Solar Heating and Cooling Program (SHCP) were not invited to participate, and the Task Group lacked any significant expertise with solar-thermal systems. When the Task submitted its final report in 2002, it consisted of an accounting of existing systems and a list of the perceived market barriers. Without input from the SHCP, however, no move could be made to actually address those barriers. IEA Task 7, however, did recognize that the participation of the SHCP was needed, and in 1999 made an effort to initiate some discussion between the PVSP and the SHCP. The result was IEA Task 35 - PV/T Systems, which met for the first time in January of 2005. The new group intends to reevaluate the findings of Task 7, and to develop the means by which these market barriers can be overcome. The current discussion will provide an overview of existing and potential PV/T systems and their technical status. Further, it will report on the methodology established by the Task 35 work group to overcome the aforementioned market barriers. (author)

From Oil Crisis to Climate Change. Understanding CO2 Emission Trends in IEA Countries

International Nuclear Information System (INIS)

Unander, F.

2003-11-01

OECD CO2 emissions from fuel combustion increased 13% between 1990 and 2001. This signals an important shift since, over the 1973 to 1990 period, emissions only increased by 3.4%. As a result, CO2 emissions from energy use (fuel combustion) contributed 81.1% of total OECD greenhouse gas emissions in 2001 compared to 77.7% in 1990. As these figures make clear, reducing CO2 emissions from fuel combustion constitutes a key challenge to combat climate change. Developing and successfully implementing the most efficient policies for reducing CO2 emissions requires a good understanding of how factors such as income, prices, demography, economic structure, lifestyle, climate, energy efficiency and fuel mix affect energy use and resulting CO2 emissions. This paper presents selected results from the analysis of CO2 developments included in the IEA publication 'From Oil Crisis to Climate Challenge: 30 Years of Energy Use in IEA Countries'. The paper gives a brief overview of aggregate CO2 emission trends and of how recent developments in selected IEA countries compare to emissions levels implied by the Kyoto targets. A deeper understanding of the aggregate trends is provided by showing results from a decomposition analysis and by discussing developments in key end-use sectors. The full publication presents a more detailed analysis of how various factors have shaped energy use patterns and CO2 emissions since 1973. The analysis draws on a newly developed database with detailed information on energy use in the manufacturing, household, service and transport sectors. The database represents the most disaggregated information available on a consistent basis across countries and sectors. The study uses quantitative measures to illustrate the forces that drive or restrain energy use. These measures - or indicators - include: activities such as manufacturing output or heated-floor-area of homes; structural developments such as changes in manufacturing output mix or changes in the

Fernando, Alberto de Jesus

2011-01-01

Pneumatic Transfer Systems (PTS) are classified as mechanical equipment largely operated all over the world for transport of a huge sort of objects, samples and materials located at nearly terminals or even at separated ones. System applicability is often recognized in many activities, such as medicine (hospital settings, clinical analysis labs), industry (steel, automobiles, mining, chemical, food, construction), trading (gas station, movies, supermarkets, banks, e-commerce) and federal agencies (post services, federal courts, public enterprises). In the nuclear settings, PTS shows also a vast array of applications, being a part of radioisotope production, as well as short-lived radiopharmaceuticals, including 67 Ga, 201 Tl, 18 F and 123 I-ultra pure. Besides, PTS are also used at radioactive waste management plants and research institutes that apply neutron activation analysis (NAA). This work was directed toward the design and operation of a new PTS for the IEA-R1 nuclear research reactor settled at Instituto de Pesquisas Energeticas e Nucleares (IPEN) for NAA application. With this aim, it was calculated the charge of reactor core grid plate and sample transport testing. Neutron flux at irradiating position was determined as 3,70 ± 0,26 10 12 n cm -2 s -1 . (author)

A review of the IEA/NEA Projected Costs of Electricity – 2015 edition

International Nuclear Information System (INIS)

Khatib, Hisham

2016-01-01

The IEA/NEA recently issued their eighth edition of the Study on the “Projected Costs of Generating Electricity” – 2015 edition. The Study is mainly concerned with calculating the levelised cost of electricity (LCOE). The LCOE calculations are based on a levelised average life time cost approach using the discounted cash flow (DCF) method. The analysis was this year, and for the first time, performed using three discount rates (3%, 7%, and 10%). The LCOE can serve as a tool for calculating the cost of different generation technologies. However the Study's usefulness is affected by its narrow base of a limited set of countries that are not necessarily representative. It ignored the negative role of subsidies and did not provide a methodology for selective application of the discount rates and costing of carbon. The global power generation scene is changing. Generation growth in OECD countries has become very limited; simultaneously there is rapid growth of varying renewables (VRE) generation which needs special criteria for assessing its system cost. All this demands a rethinking of the application and usefulness of the LCOE in future generation planning. - Highlights: • LCOE is a useful tool for economics of generation technologies. • The IEA/NEA study did not cover fully the required criteria for assessment. • It ignored interpretation of: the discount rate, carbon costing and subsidies. • The world energy scene is changing, this requires reassessment of LCOE.

Energy markets in the 1990's and beyond: A comparison of energy intensity in the United States and Japan

Science.gov (United States)

McDonald, S. C.

1989-10-01

A comparative analysis is provided of energy intensity in the U.S. and Japan. According to aggregate International Energy Agency (IEA) data, the U.S. has one of the most energy-intensive economies while Japan has one of the least. Energy-intensity measures are constructed and examined which that are more detailed than aggregate measures used by the IEA to see if they can better explain these differences. The year chosen for this analysis is 1985. The issue of energy intensity may become particularly critical if scientific findings on global climate change and greenhouse emissions lead to negotiations on restricting carbon emissions. The burning of fossil fuels is the most important anthropogenic source of carbon emissions. As shown by this analysis, developing a consistent and fair set of goals for each country for carbon emissions, which are interlocked with energy intensity, may be a difficult task.

IEA HPP Annex 32 - Economical heating and cooling systems for low-energy houses. State-of-the-art report Norway

International Nuclear Information System (INIS)

Stene, Joern

2007-04-01

Norway is a member of Annex 32, 'Economical heating and cooling systems for low-energy houses' (2006-2008), organized under the umbrella of the International Energy Agency (IEA) and the IEA Heat Pump Programme (HPP). The 9 participating countries are Switzerland (Operating Agent), Austria, Canada, Germany, Japan, the Netherlands, Norway, Sweden and the USA. The Norwegian participation is financed by Enova SF, and SINTEF Energy Research is responsible for planning and carrying out the Norwegian activities. Task 1 of the project is a state-of the art analysis of the low-energy building market and heat pump technologies applied in this type of buildings. Heating demands for low-energy houses and passive houses in Norwegian climate are characterized as follows: The ratio of the annual heating demand for hot water heating and the total annual heating demand of the houses typically range from 40 to 85 percent, and the heating season for space heating and heating of ventilation air range from about 5-7 and 4-6 months per year for semi-detached houses and flats, respectively (Oslo climate). In comparison, the heating season for semi-detached houses and flats constructed in accordance with the Norwegian building codes of 1997 is 8 and 9 months, respectively. Development companies for residential properties, co-operative building societies as well as housing manufactures are now showing great interest in low-energy houses and passive houses. According to The Norwegian State Housing Bank, almost 10.000 residences with low-energy or passive house standard are now being planned, constructed or have been completed. The projects include single-family houses, semi-detached houses, row houses, block of flats and apartment buildings. The main focus in these projects has been on the architectural design, building construction and efficient ventilation systems, and less on the heating (and cooling) systems. The heat pump market in this market segment is regarded to be promising due to

Energy security and the IEA ExCo on combustion

Energy Technology Data Exchange (ETDEWEB)

Hutchinson, P. [Hutchinson Consultant (United Kingdom)

2009-07-01

Energy security is an issue for those nations which consume more energy than is available from indigenous sources. A failure to secure adequate energy supplies at an acceptable price prejudices both national and economic security. Energy security is therefore a significant policy issue. A discussion of energy security and the International Energy Agency ExCo on combustion was offered in this presentation. The purpose of the discussion was to determine if a task or set of tasks on combustion research related to energy security should be launched; the structure of such a task; topics of interest; who would wish to participate; who would lead the collaboration; and the next steps. The presentation discussed the proper understanding and analysis of energy security and the interactions between international politics; defence; economics and economic development; present and future technologies; national infrastructure; resource distribution; and environmental science and politics. The presentation also discussed whether there was a shortage of energy, world reserves of crude oil, coal, and hydrocarbons. Oil supply disruptions and nominal and real world oil prices were also discussed. Options for addressing energy security were presented, with particular reference to increasing the energy intensity of the economy; using a wide range of different fuels such as coal; developing indigenous supplies such as renewables; and developing a reliable long life energy source. It was concluded that imports of energy can be reduced when energy security improves. tabs., figs.

CSP electricity cost evolution and grid parities based on the IEA roadmaps

International Nuclear Information System (INIS)

Hernández-Moro, J.; Martínez-Duart, J.M.

2012-01-01

The main object of this paper consists in the development of a mathematical closed-form expression for the evaluation, in the period 2010–2050, of the levelized costs of energy (LCOE) of concentrating solar power (CSP) electricity. For this purpose, the LCOE is calculated using a life-cycle cost method, based on the net present value, the discounted cash flow technique and the technology learning curve approach. By this procedure, the LCOE corresponding to CSP electricity is calculated as a function of ten independent variables. Among these parameters, special attention has been put on the evaluation of the available solar resource, the analysis of the IEA predicted values for the cumulative installed capacity, the initial (2010) cost of the system, the discount and learning rates, etc. One significant contribution of our work is that the predicted evolution of the LCOEs strongly depend, not only on the particular values of the cumulative installed capacity function in the targeted years, but mainly on the specific curved time-paths which are followed by this function. The results obtained in this work are shown both graphically and numerically. Finally, the implications that the results could have in energy planning policies and grid parity calculations are discussed. - Highlights: ► A mathematical closed expression has been developed for calculating the evolution of CSP electricity costs. ► Our technique for the prediction of CSP electricity costs and grid parities is based on IEA Roadmaps. ► The time-table (2010–2050) of cumulative installed CSP capacity is key to electricity cost predictions. ► CSP grid parities can occur within next decade for sites with proper solar resources.

In 1999, the management of the IEA-R1 Research Reactor (pool type - 5 MWth), located at IPEN/CNEN-SP, started the evaluation of the Reactor Pool Water Retreatment System to identify operational aspects, which could compromise the operators safety. The purpose was to identify and propose enhancements to the system which would be installed to substitute for the existing one. This process was conducted through a qualitative study of the system in operation. This study was carried out by a team composed of specialists in reactor operation, systems maintenance and radiological protection, and one safety analyst. The study consisted, basically, in local inspections to verify the physical and operational conditions of each equipment / component as well as aspects related to maintenance activities of the system. The process control and the operator procedures associated with the retreatment of the reactor pool water were also reviewed. The methodology adopted to develop the study was based in process hazard analysis technique named Safety Checklist. This paper presents a summary of this study and the main results obtained. Some operational and safety problems identified, the prevention and/or correction means to avoid them, and the recommendations and suggestions that have been implemented to the new design of the IEA-R1 Reactor Water Retreatment System, whose installation was concluded in 2003, are also presented.

Energy policies of IEA countries: Denmark 2006 review

Energy Technology Data Exchange (ETDEWEB)

NONE

2006-12-18

Denmark has had a very pro-active energy policy in both energy efficiency and renewable energy while at the same time opening its gas and power markets to competition. The share of renewable energy has increased dramatically, going from 3% of all electricity generation in 1990 to 25% in 2004. At the same time, the government's renewable support policies up to the early 2000s came with a high cost for consumers and taxpayers. However, the current government is very attentive to cost-effectiveness and inclined to market-based approaches. Greater use of cost-benefit analysis, including for offshore wind plants, is crucial in shaping future policies. The review indicates that energy efficiency programmes have historically been more cost-effective than renewable energy programmes in lowering emissions and enhancing energy security. Denmark's energy intensity is 35% below the IEA average, due in substantial part to the government's efforts to improve efficiency. This policy provides an excellent example for other countries, although the review notes that more should be done for transport efficiency.

1997-12-31

This IEA report provides a comprehensive in-depth assessment of the energy policies of Turkey, including recommendations on future policy developments. The report highlights the rapid increase in Turkey`s energy consumption and the large investments needed to meet the demand growth. Turkey has sought to attract private inward investment in the energy sector, in particular in electricity, through build-own-operate and build-operate-transfer schemes and transfers of operating rights. Turkey needs to set up a stable legal framework to continue this policy. It needs to push forward with market reforms, as well as to create a level playing field for competition, with energy prices reflecting the true costs of various fuels. Natural gas consumption is also expected to continue to increase. The new regulatory framework should be designed to encourage more rapid increase in the use of gas and more corresponding investments. Turkey is situated near the Caspian Sea, where natural gas and oil production are expected to increase substantially. The report describes projects for oil and natural gas pipelines. 33 figs., 31 tabs., 4 apps.

Application of non-destructive methods for qualification of the U3O8-Al and U3Si2-Al dispersion fuels in the IEA-R1 Reactor

International Nuclear Information System (INIS)

Silva, Jose Eduardo Rosa da

2011-01-01

IPEN/CNEN-SP manufactures fuels to be used in its nuclear research reactor - the IEA-R1. To qualify those fuels, it is necessary to check if they have a good performance under irradiation. As Brazil doesn't have nuclear research reactors with high neutron fluxes, or suitable hot cells for carrying out post-irradiation examination of nuclear fuels, IPEN/CNEN-SP has conducted a fuel qualification program based on the use of uranium compounds, internationally tested and qualified to be used in research reactors, and has gotten experience in the technological development stages for the manufacturing of fuel plates, irradiation and non-destructive post-irradiation testing. Fuel elements containing low volume fractions of fuel in the dispersion were manufactured and irradiated successfully directly in the core of the IEA-R1. However, there are plans to increase the uranium density of these fuels. The objective of this thesis work was to study and to propose a set of non-destructive methods to qualify the dispersions fuels U 3 O 8 -Al e U 3 Si 2 -Al with high uranium density produced at IPEN/CNEN-SP. For that, the irradiation resources in the IEA-R1, and the application of non-destructive methods in the reactor pool available in the Institution were considered. The proposal is to specify, manufacture and irradiate fuel mini plates in IEA-R1 at the maximum densities, qualified internationally, and to monitor their general conditions during the period of irradiation, using non-destructive methods in the reactor pool. In addition to the non-destructive visual inspection and sipping methods, already used at the Institution, the infrastructure for dimensional sub-aquatic testing to evaluate the swelling of irradiated fuel mini plates was completed. The analyses of the results will provide means to assess and decide whether or not to continue with the irradiation of mini plates, until the desired burnup for the irradiation tests at IEA-R1 are reached.

Thirty-five years after the Agency's founding, the IEA responsibility for ensuring access to global oil supplies is still a core mandate -- but new energy-related concerns have arisen. Energy security is no longer only about oil. And the industrialised nations of the world are no longer the only major consumers of energy. Climate change driven by greenhouse gas emissions -- 60% of which derive from energy production or use -- is a growing threat. So energy policy was tasked with a new objective: to cut greenhouse gas emissions while maintaining economic growth.

Norwegian contribution to the IEA Annex 24 - Absorption Machines for Heating and Cooling; IEA annex 24. Absorpsjonsmaskin for oppvarming og kjoeling

This report summarizes the Norwegian contribution to the IEA Annex 24 - Absorption Machines for Heating and Cooling in Future Energy Systems. Thermally operated heat pumps and coolers have not been widely used in Norway. They are not economically competitive compared to compression heat pumps because of Norway's cheap hydroelectric power. If the present trend in Norway's use of electricity persists, Norway will soon be dependent on imported electric power. This calls for measures to reduce the consumption of electricity, and the role of absorption heat pumps will be of increasing importance, especially for cooling purposes. For larger commercial buildings that require climate cooling, absorption coolers based on waste heat may have a good total economy. Industrial processes that have an excess of heat at a high temperature and which need cooling, may profit from the use of this type of cooler. Information dissemination is important for efficient use of this technology. The research work done at Institute of energy technology, Kjeller, Norway, is an important contribution to this end.

1996-01-01

As part of the IEA's on-going analysis of Member countries' energy policies, this review assess the Netherlands and offers recommendations taking account of major reforms announced by the Dutch Government in December 1995. The prominence of environmental objectives in Dutch energy policy and the widespread use of voluntary long-term agreements with industry provide constructive lessons for other countries. Targets for energy efficiency and renewability are especially ambitious. Moreover, the Dutch Government has made an important contribution to environmental policy by striving for a combination of market liberalization and a sustainable energy economy. The review recommends that market reforms be further developed, if necessary in the context of developments in European energy market policy. Gas pricing and a tendency for over-capacity to develop in the electricity sector are particular areas of discussion in the report. The review also draws attention to potentially high economic costs which may arise form energy-environment policies and affect the competitiveness of Dutch industry. (author). 18 figs., 13 tabs

IPEN’s research reactor, IEA-R1, an open pool type research reactor moderated and cooled by light water. High quality water is a key factor in preventing the corrosion of the spent fuel stored in the pool. Leaching of radionuclides from the corroded fuel cladding may be prevented by an efficient water treatment and purification system. However, as a safety management policy, IPEN has adopted a water chemistry control which periodically monitors the levels of uranium (U) and silicon (Si) in the pool’s reactor, since IEA-R1 employs U3Si2-Al dispersion fuel. An analytical method was developed and validated for the determination of uranium and silicon by ICP OES. This work describes the validation process, in a context of quality assurance, including the parameters selectivity, linearity, quantification limit, precision and recovery.

This report for the International Energy Agency (IEA) made by Task 10 of the Photovoltaic Power Systems (PVPS) programme takes a look at urban photovoltaic electricity policies. The mission of the Photovoltaic Power Systems Programme is to enhance the international collaboration efforts which accelerate the development and deployment of photovoltaic solar energy as a significant and sustainable renewable energy option. The objective of Task 10 is stated as being to enhance the opportunities for wide-scale, solution-oriented application of photovoltaics in the urban environment. The goal of the study presented was to evaluate a standardised basis for urban policies regarding photovoltaic integration in a set of cities in the countries participating in the IEA's Task 10, Urban Scale PV. The investigation was focused on three topics: the present state of the policies, the prospects for future policies fostering photovoltaic deployment and the prospects for future policies to cope with large-scale photovoltaic integration. The first section analyses the state of the policies; this analysis is then confirmed in section 2, which deals with present obstacles to PV deployment and solutions to overcome them. The third section investigates future prospects for PV deployment with the question of mastering large scale integration. The report concludes that cities could formulate urban solutions by developing integrated, specific provisions for PV deployment in their urban infrastructure planning.

Characterization of cartridge filters from the IEA-R1 Nuclear Reactor

The management of radioactive waste ensures safety to human health and the environment nowadays and for the future, without overwhelming the upcoming generations. The primary characterization of radioactive waste is one of the main steps in the management of radioactive waste. This step permits to choose the best treatment for the radioactive waste before forwarding it to its final disposal. The aim of the present work is the primary characterization of cartridge filters from the IEA-R1 nuclear reactor utilizing gamma-ray spectrometry, and the method of Monte Carlo for calibration. The IEA-R1 is located in the Nuclear and Energy Research Institute (IPEN - CNEN) in the city of Sao Paulo, Brazil. Cartridge filters are used for purification of the cooling water that is pumped through the core of the pool type nuclear research reactors. Once worn out, these filters are replaced and then become radioactive waste. Determination of the radioactive inventory is of paramount importance in the management of such radioactive waste, and one of the main methods for doing so is the gamma-ray spectrometry, which can identify and quantify high energy photon emitters. The technique chosen for the characterization of radioactive waste in the present work is the gamma-ray spectrometry with High purity Germanium (HPGe) detectors. From the energy identified in the experimental spectrum, three radioisotopes were identified in the cartridge filter: 108m Ag, 110m Ag, 60 Co. For the estimated activity of the filter, the calibration in efficiency was made utilizing the MCNP4C code of the Monte Carlo method. Such method was chosen because there is no standard source available in the same geometry of the cartridge filter, therefore a simulation had to be developed in order to reach a calibration equation, necessary to estimate the activity of the radioactive waste. The results presented an activity value in the order of MBq for all radioisotopes. (authors)

In 1999, the management of the IEA-R1 Research Reactor (pool type - 5 MWth), located at IPEN/CNEN-SP, started the evaluation of the Reactor Pool Water Retreatment System to identify operational aspects, which could compromise the operators safety. The purpose was to identify and propose enhancements to the system which would be installed to substitute for the existing one. This process was conducted through a qualitative study of the system in operation. This study was carried out by a team composed of specialists in reactor operation, systems maintenance and radiological protection, and one safety analyst. The study consisted, basically, in local inspections to verify the physical and operational conditions of each equipment / component as well as aspects related to maintenance activities of the system. The process control and the operator procedures associated with the retreatment of the reactor pool water were also reviewed. The methodology adopted to develop the study was based in process hazard analysis technique named Safety Checklist. This paper presents a summary of this study and the main results obtained. Some operational and safety problems identified, the prevention and/or correction means to avoid them, and the recommendations and suggestions that have been implemented to the new design of the IEA-R1 Reactor Water Retreatment System, whose installation was concluded in 2003, are also presented.

Highlights: • A set of advanced system thermal hydraulic codes are benchmarked against IFA of IEA-R1. • Comparative safety analysis of IEA-R1 reactor during LOFA by 7 working teams. • This work covers both experimental and calculation effort and presents new out findings on TH of RR that have not been reported before. • LOFA results discrepancies from 7% to 20% for coolant and peak clad temperatures are predicted conservatively. - Abstract: In the framework of the IAEA Coordination Research Project on “Innovative methods in research reactor analysis: Benchmark against experimental data on neutronics and thermal hydraulic computational methods and tools for operation and safety analysis of research reactors” the Brazilian research reactor IEA-R1 has been selected as reference facility to perform benchmark calculations for a set of thermal hydraulic codes being widely used by international teams in the field of research reactor (RR) deterministic safety analysis. The goal of the conducted benchmark is to demonstrate the application of innovative reactor analysis tools in the research reactor community, validation of the applied codes and application of the validated codes to perform comprehensive safety analysis of RR. The IEA-R1 is equipped with an Instrumented Fuel Assembly (IFA) which provided measurements for normal operation and loss of flow transient. The measurements comprised coolant and cladding temperatures, reactor power and flow rate. Temperatures are measured at three different radial and axial positions of IFA summing up to 12 measuring points in addition to the coolant inlet and outlet temperatures. The considered benchmark deals with the loss of reactor flow and the subsequent flow reversal from downward forced to upward natural circulation and presents therefore relevant phenomena for the RR safety analysis. The benchmark calculations were performed independently by the participating teams using different thermal hydraulic and safety

Task 15 of the Hydrogen Implementation Agreement of the International Energy Agency is to advance the science of biophotosynthesis of hydrogen, which is the biological production of hydrogen from water and sunlight using microalgal photosynthesis. A practical process for biophotolysis would result in an innovative biological source of sustainable and environmentally benign renewable energy source. Japan, Norway, Sweden and the United States initially committed to the project. Since then Canada, the Netherlands and the United Kingdom have joined. The current task is to produce hydrogen from both green algae and cyanobacteria with focus on early-stage applied research on biophotolysis processes with intermediate carbon dioxide fixation. Significant advances have also occurred in the scientific field of cyanobacterial biohydrogen. Cyanobacteria has enzymes that metabolise hydrogen. Photosynthetic cyanobacteria have simple nutritional requirements and can grow in air, water, or mineral salts with light as the only source of energy. This research will help provide the advances needed to achieve practical efficiencies and cost objectives of biological hydrogen production. tabs., figs.

Slovakia has implemented impressive energy reforms over the recent past, a unique performance in Central and Eastern Europe. The 2000 energy policy prioritised market reforms and sectoral policies, notably on energy security and environment, in order to comply with EU requirements, which were largely met at the time of the country’s EU accession in 2004. Also, Slovakia established new regulations, notably cost reflective pricing enforced by an independent energy regulator, thereby attracting significant foreign direct investment. Notably, this rapid transition has occurred without disruption in this key energy transit country. New challenges ahead include strengthening energy security by diversification, opening energy markets and integrating them into the EU, strongly increasing energy efficiency to offset the high economic burden of energy prices and to help better controlling pollution and CO2 emissions in line with EU and international obligations. This review analyses the Slovak energy sector and policies, and provides recommendations for the government. It is a comprehensive assessment of what constitutes a remarkable case study of effective energy reforms in an economy in transition, which has applied for IEA membership.

It also looks at the benefits of increased RD&D funding in terms of technological advancement and cost improvement. It covers renewable energy technologies in the early research stage through to those that have reached a level of maturity. It also lists national renewable energy RD and D trends in IEA member countries.

Impact of uranium concentration reduction in side plates of the fuel elements of IEA-R1 reactor on neutronic and thermal hydraulic analyses; Impacto da reducao na concentracao de uranio nas placas laterais dos elementos combustiveis do reator IEA-R1 nas analises neutronica e termo-hidraulica

This master thesis presents a study to verify the impact of the uranium concentration reduction in the side plates of the reactor IEA-R1 fuel elements on the neutronic and thermal-hydraulic analyses. To develop such study, a previous IPEN-CNEN/SP research was reproduced by simulating the fuel elements burn-up, with side plate uranium density reduced to 50, 60 and 70% of the standard fuel element plates. This research begins with the neutronic analysis using the computer code HAMMER and the first step consists in the calculation of the cross section of all materials presented at the reactor core, with their initial concentration; the second step consists in the calculation of the fast and thermal neutron group fluxes and power densities for fuel elements using the computer code CITATION. HAMMER output data is used as input data. Once the neutronic analysis is finished and the most critical fuel elements with highest power density have been defined, the thermal-hydraulics analysis begins. This analysis uses MCTR-IEA-R1 thermal-hydraulics model, which equations are solved by commercial code EES. Thermalhydraulics analysis input is the power density data calculated by CITATION: it is considered the highest power density on each fuel element, where there is a higher energy release and, consequently, higher temperatures. This data is used on energy balance equations to calculate temperatures on critical fuel element regions. Reactor operation comparison for three different uranium densities on fuel side plates is presented. Uranium density reduction contributes to the cladding surface temperature to remain below the established limit, as reactor operation safety requirement and it does not affect significantly fuel element final burn-up nor reactor reactivity. The reduction of uranium in the side plates of the fuel elements of the IEA-R1 showed to be a viable option to avoid corrosion problems due to high temperatures. (author)

Application of TEMPPC code to the IEA-R1 nuclear reactor core hydrothermal calculations operating at 2 MW for determining the minimal coolant flow

A thermohydraulic study of the IEA-R1 nuclear reactor core on steady-state operating condition and forced convection, is presented. The objective of this calculation is to obtain the minimal flow rate of coolant necessary at the reactor core, limited by the temperature associated to the beginning of nucleate boiling over the fuel plates at a normal operating power (2MW) for a certain inlet coolant temperature. The coolant system safety level is also calculated in this paper, which is divided in three steps: thermohydraulic calculation, without using the uncertainty factors and, after that, considering these factor by two methods: the statistical and the conventional ones. Whichever the method accepted, the results obtained by the program TEMPPC show a great safety margin with respect to the termohydraulic parameters from the IEA-R1 nuclear reactor. (Author) [pt

Thermochemical conversion in this study is limited to fast pyrolysis, upgrading of fast pyrolysis oils, and gasification. Environmental impacts of all types were considered within the project, but primary emphasis was on discharges to the land, air, and water during and after the conversion processes. The project discussed here is divided into five task areas: (1) pyrolysis oil analysis; (2) hydrotreating of pyrolysis oil; (3) gas treatment systems for effluent minimization; (4) strategic analysis of regulatory requirements; and (5) support of the IEA Environmental Systems Activity. The pyrolysis oil task was aimed at understanding the oil contaminants and potential means for their removal. The hydrotreating task was undertaken to better define one potential means for both improving the quality of the oil but also removing contaminants from the oil. Within Task 3, analyses were done to evaluate the results of gasification product treatment systems. Task 4 was a review and collection of regulatory requirements which would be applicable to the subject processes. The IEA support task included input to and participation in the IEA Bioenergy activity which directly relates to the project subject. Each of these tasks is described along with the results. Conclusions and recommendations from the overall project are given.

Analysis of the IEA-R1 reactor start-up procedures - an application of the HazOp method

International Nuclear Information System (INIS)

Sauer, Maria Eugenia Lago Jacques

2000-01-01

An analysis of technological catastrophic events that took place in this century shows that human failure and vulnerability of risk management programs are the main causes for the occurrence of accidents. As an example, plants and complex systems where the interface man-machine is close, the frequency of failures tends to be higher. Thus, a comprehensive knowledge of how a specific process can be potentially hazardous is a sine qua non condition to the operators training, as well as to define and implement more efficient plans for loss prevention and risk management. A study of the IEA-R1 research reactor start-up procedures was carried out, based upon the methodology Hazard and Operability Study (HazOp). The analytical and qualitative multidisciplinary HazOp approach provided means to a comprehensive review of the reactor start-up procedures, contributing to improve the understanding of the potential hazards associated to deviations on performing this routine. The present work includes a historical summary and a detailed description of the HazOp technique, as well as case studies in the process industries and the use of expert systems in the application of the method. An analysis of 53 activities of the IEA-R1 reactor start-up procedures was made, resulting in 25 recommendations of changes covering aspects of the project, operation and safety of the reactor. Eleven recommendations have been implemented. (author)

Measurement and calculation of spatial and energetic neutron flux in the IEA-R1 reactor core

Bittelli, U.D.

1988-01-01

This work presents spatial and energetic flux distribution measured in the IEA-R1 reactor core. The thermal neutron flux was measured by gold activation foils (bare and covered with cadmium) in the fuel element number 108 (reaction: 197 Au(n,γ) 198 Au) at 451W overall reactor power. The fast neutron flux was measured by indium activation foils (reaction: 115 In(n,n') 115m In) in the fuel elements number 94 at 4510W overall reactor power. The neutron energy spectrum was adjusted by SAND II code with the data produced by the irradiation of seven activation detectors in the fuel element number 94 at 4510 W overall reactor power. The following reactions were used: 58 Fe(n,γ) 59 Fe, 232 Th(n,γ) 233 Th, 197 Au(n,γ) 198 Au, 59 Co(n,γ) 60 Co, 54 Fe(n,p) 54 Mn, 24 Mg(n,p) 24 Na, 47 Ti(n,p) 47 Sc, 48 Ti(n,p) 48 Sc and 115 In(n,n') 115m In. The experimental results compared to those obtained by CITATION (spatial distribution flux) and HAMMER (energetic distribution flux) code, showed good agreement. The results presented in this work are a good contribution for a better knowledge of spatial and energetic neutron flux distribution in the IEA-R1 reactor core, besides that the experimental procedure is easily applicable to another situations.

Use of self powered neutron detectors in the IEA-R1 reactor

International Nuclear Information System (INIS)

Galo Rocha, F. del.

1989-01-01

A survey of self-powered neutron detectors, SPND, which are used as part of the in-core instrumentation of nuclear reactors is presented. Measurements with Co and Er SPND's were made in the IEA-R1 reactor for determining the neutron flux distribution and the integral reactor power. Due to the size of the available detectors, the neutron flux distribution could not be obtained with accuracy. The results obtained in the reactor power measurements demonstrate that the SPND have the linearity and the quick response necessary for a reactor power channel. This work also presents a proposed design of a SPND using Pt as wire emissor. This proposed design is based in the experience gained in building two prototypes. The greatest difficulties encountered include materials and technology to perform the delicate weldings. (author)

2009-07-01

Neutronic, thermal-hydraulics and accident analysis calculations were developed to estimate the safety of an irradiation device placed in the IEA-R1 reactor core. The irradiation device will be used to receive miniplates of U{sub 3}O{sub 8}-Al e U{sub 3}Si{sub 2}-Al dispersion fuels, LEU type (19.9% of {sup 235}U), with uranium densities of, respectively, 3.0 gU/cm{sup 3} and 4.8gU/cm{sup 3}. The fuel miniplates will be irradiated to nominal {sup 235}U burnup levels of 50% and 80%, in order to qualify the above high-density dispersion fuels to be used in the Brazilian Multipurpose Reactor, now in the conception phase. For the neutronic calculation, the computer code CITATION was utilized. The computer code FLOW was used to calculate the coolant flow rate in the irradiation device, allowing the determination of the fuel miniplate temperatures with the computer model MTRCR-IEA-R1. A postulated Loss of Coolant Accident (LOCA) was analyzed with the computer codes LOSS and TEMPLOCA, allowing the calculation of the fuel miniplate temperatures after the reactor pool draining. The calculations showed that the irradiation of the fuel miniplates will happen without any adverse consequence in the IEA-R1 reactor. (author)

Nuclear Energy Agency task group on Radiological Characterisation for Decommissioning of Nuclear Installations

International Nuclear Information System (INIS)

Larsson, Arne; Weber, Inge

2016-01-01

Radiological characterisation plays a significant role in the process of decommissioning of shut-down nuclear facilities in order to ensure the protection of the environment and radiation safety. At all stages of a decommissioning programme or project, adequate radiological characterisation is of crucial importance, not least from a material and waste perspective. The radiological characterisation is a key element for planning, controlling and optimising decommissioning and dismantling activities. Experience has shown that data and information from the operation of a facility can - supplemented by recently collected and analysed data and information - be of crucial importance for decisions on waste management and for characterisation of radioactive waste. Once the dismantling has been done, some information may be hard, costly or even impossible to obtain later in the waste management process. This was the reason why the Working Party on Decommissioning and Dismantling (WPDD) of the OECD Nuclear Energy Agency (NEA) decided in late 2013 to extend the mandate of the Task Group on Radiological Characterisation and Decommissioning (TGRCD) for a second phase focusing on nuclear facility characterisation from a waste and material end-state perspective whereas the first phase focused on overall strategies of radiological characterisation. This paper gives an overview of the activities and findings within both phases up to now. (authors)

NONE

2002-09-15

This Practice Guide issued by the Photovoltaic Power Systems (PVPS) group of the International Energy Agency (IEA) summarises how insufficient financing, the low incomes of the potential clients in remote rural areas and the high initial investment costs for the Solar Home System (SHS) are the factors responsible for insufficient progress in this area. The findings of the study such as access to finance, subsidies, formal and informal intermediaries and alternative financing solutions are discussed. SHS operating costs, possible higher priorities for other commodities and other market-driven factors are discussed. The report notes that most other reports concentrate more on technical and institutional rather than on the underlying financing schemes and associated data. Recommendations made deal with political aspects as well as technical, financial and awareness issues.

Constructing agency: The role of language

Directory of Open Access Journals (Sweden)

Caitlin M Fausey

2010-10-01

Full Text Available Is agency a straightforward and universal feature of human experience? Or is the construction of agency (including attention to and memory for people involved in events guided by patterns in culture? In this paper we focus on one aspect of cultural experience: patterns in language. We examined English and Japanese speakers’ descriptions of intentional and accidental events. English and Japanese speakers described intentional events similarly, using mostly agentive language (e.g., She broke the vase. However, when it came to accidental events English speakers used more agentive language than did Japanese speakers. We then tested whether these different patterns found in language may also manifest in cross-cultural differences in attention and memory. Results from a non-linguistic memory task showed that English and Japanese speakers remembered the agents of intentional events equally well. However, English speakers remembered the agents of accidents better than did Japanese speakers, as predicted from patterns in language. Further, directly manipulating agency in language during another laboratory task changed people’s eye-witness memory, confirming a possible causal role for language. Patterns in one’s linguistic environment may promote and support how people instantiate agency in context.

We keep on truckin': Trends in freight energy use and carbon emissions in 11 IEA countries

International Nuclear Information System (INIS)

Eom, Jiyong; Schipper, Lee; Thompson, Lou

2012-01-01

Based on detailed national and international data on freight transportation, we analyze trends in freight CO 2 emissions in 11 IEA countries from the earliest year of data availability to 2007–2010. The cross-country comparison of the freight transportation sector indicates that per capita CO 2 emissions span a wide range and are mostly determined by local needs without full knowledge or coordination with policies and practices in other countries. Over the last several decades, while many developed countries have experienced decreased coupling between total freight activity (measured in tonne-km) and income, no major indication of decreased coupling between trucking and income was found. Rather, the coupling has been strengthened in many countries due to a continued increase in the share of trucking in total freight activity. The energy intensity of trucking has exhibited very large variation among the countries, and its recent international trends are mixed, providing greater challenges to reduce freight CO 2 emissions. Modal shift toward rail away from truck presents a sizeable opportunity to reduce freight CO 2 emissions, although the potential gain varies widely among the countries. - Highlights: ► We analyze trends in freight CO 2 emissions in 11 IEA countries. ► Many of them experienced decreased coupling between freight and income. ► No major indication of decoupling was found between trucking and income. ► The energy intensity of trucking exhibited very large variation. ► The trends of trucking energy intensity are mixed. ► There is a huge opportunity of reducing emissions by shifting toward rail.

Uncovering effects of self-control and stimulus-driven action selection on the sense of agency.

Science.gov (United States)

Wang, Yuru; Damen, Tom G E; Aarts, Henk

2017-10-01

The sense of agency refers to feelings of causing one's own action and resulting effect. Previous research indicates that voluntary action selection is an important factor in shaping the sense of agency. Whereas the volitional nature of the sense of agency is well documented, the present study examined whether agency is modulated when action selection shifts from self-control to a more automatic stimulus-driven process. Seventy-two participants performed an auditory Simon task including congruent and incongruent trials to generate automatic stimulus-driven vs. more self-control driven action, respectively. Responses in the Simon task produced a tone and agency was assessed with the intentional binding task - an implicit measure of agency. Results showed a Simon effect and temporal binding effect. However, temporal binding was independent of congruency. These findings suggest that temporal binding, a window to the sense of agency, emerges for both automatic stimulus-driven actions and self-controlled actions. Copyright © 2017 Elsevier Inc.

Impact of uranium concentration reduction in side plates of the fuel elements of IEA-R1 reactor on neutronic and thermal hydraulic analyses

International Nuclear Information System (INIS)

Rios, Ilka Antonia

2013-01-01

This master thesis presents a study to verify the impact of the uranium concentration reduction in the side plates of the reactor IEA-R1 fuel elements on the neutronic and thermal-hydraulic analyses. To develop such study, a previous IPEN-CNEN/SP research was reproduced by simulating the fuel elements burn-up, with side plate uranium density reduced to 50, 60 and 70% of the standard fuel element plates. This research begins with the neutronic analysis using the computer code HAMMER and the first step consists in the calculation of the cross section of all materials presented at the reactor core, with their initial concentration; the second step consists in the calculation of the fast and thermal neutron group fluxes and power densities for fuel elements using the computer code CITATION. HAMMER output data is used as input data. Once the neutronic analysis is finished and the most critical fuel elements with highest power density have been defined, the thermal-hydraulics analysis begins. This analysis uses MCTR-IEA-R1 thermal-hydraulics model, which equations are solved by commercial code EES. Thermalhydraulics analysis input is the power density data calculated by CITATION: it is considered the highest power density on each fuel element, where there is a higher energy release and, consequently, higher temperatures. This data is used on energy balance equations to calculate temperatures on critical fuel element regions. Reactor operation comparison for three different uranium densities on fuel side plates is presented. Uranium density reduction contributes to the cladding surface temperature to remain below the established limit, as reactor operation safety requirement and it does not affect significantly fuel element final burn-up nor reactor reactivity. The reduction of uranium in the side plates of the fuel elements of the IEA-R1 showed to be a viable option to avoid corrosion problems due to high temperatures. (author)

IEA energy policies review: the European Union

Energy Technology Data Exchange (ETDEWEB)

NONE

2008-09-04

For the first time, the IEA has reviewed the energy policies of the European Union which shape the energy use of almost 500 million citizens in 27 EU member countries. A unique entity governed under complex and almost constantly evolving structures, the EU constitutes a challenge for energy policy makers. Its energy policy has a global impact, not only because of its 16% share of world energy demand, but also because of the EU leadership in addressing climate change. Strong policy drives are underway in the EU to achieve the completion of the internal energy market, increase renewable energy supply, reduce CO2 emissions and make the EU more energy-efficient. Concerns about security of supply have also led to a greater focus on improved energy relations with supplier countries, and new institutional structures are being put in place. How much progress has been made in the field of security, internal market and external energy policies? And in which of these areas has the EU already implemented a fully integrated policy? This publication addresses these questions and also analyses the impact of the most recent major EU policy measures, in particular the Energy and Climate Package of January 2008 and the 3rd Liberalisation Package of September 2007. This book finds that both of these proposals are highly ambitious. But implementing them and reviewing both volume and allocation of energy R and D will be necessary to achieve a sustainable energy future in a fully competitive integrated EU energy market.

Music is known to be capable of reducing perceived exertion during strenuous physical activity. The current interpretation of this modulating effect of music is that music may be perceived as a diversion from unpleasant proprioceptive sensations that go along with exhaustion. Here we investigated the effects of music on perceived exertion during a physically strenuous task, varying musical agency, a task that relies on the experience of body proprioception, rather than simply diverting from it. For this we measured psychologically indicated exertion during physical workout with and without musical agency while simultaneously acquiring metabolic values with spirometry. Results showed that musical agency significantly decreased perceived exertion during workout, indicating that musical agency may actually facilitate physically strenuous activities. This indicates that the positive effect of music on perceived exertion cannot always be explained by an effect of diversion from proprioceptive feedback. Furthermore, this finding suggests that the down-modulating effect of musical agency on perceived exertion may be a previously unacknowledged driving force for the development of music in humans: making music makes strenuous physical activities less exhausting.

Tackling investment challenges in power generation - in IEA countries

In most IEA countries a new investment cycle in power generation is looming. A window of opportunity now exists to push for a cleaner and more efficient generation portfolio that could transform the power sector and help to build a more sustainable infrastructure lasting over the next 40-50 years. What are the recent trends and prospects for investment in power generation? What are the main drivers and barriers? This book assesses these issues and gives special emphasis to the question of how uncertainties may affect investment decisions. Uncertainties on CO{sub 2} constraints, on power plant licensing, on acceptability of nuclear power, on local opposition to any new energy infrastructure, on government support for specific generation technologies and on government policies on energy efficiency are particularly disturbing. Market liberalisation can also be a key uncertainty, but this may be greatly reduced and deliver considerable benefits if liberalisation is implemented whole-heartedly and backed by on-going government commitment. Government action is urgently needed: to reduce regulatory uncertainty for investors, to establish effective competitive markets and to give firm policy directions in those areas where markets fall short, such as in taking environmental costs and security of supply into account.

Multivariate statistics comprise a set of statistical methods used in situations where many variables are database space subsets. Initially applied to human, social and biological sciences, these methods are being applied to many other areas such as education, geology, chemistry, physics, engineering, and many others. This spectra expansion was possible due to recent technological development of computation hardware and software that allows high and complex databases to be treated iteratively enabling further analysis. Following this trend, the neural networks called Self-Organizing Maps are turning into a powerful tool on visualization of implicit and unknown correlations in big sized database sets. Originally created by Kohonen in 1981, it was applied to speech recognition tasks. The SOM is being used as a comparative parameter to evaluate the performance of new multidimensional analysis methodologies. Most of methods require good variable input selection criteria and SOM has contributed to clustering, classification and prediction of multidimensional engineering process variables. This work proposes a method of applying SOM to a set of 58 IEA-R1 operational variables at IPEN research reactor which are monitored by a Data Acquisition System (DAS). This data set includes variables as temperature, flow mass rate, coolant level, nuclear radiation, nuclear power and control bars position. DAS enables the creation and storage of historical data which are used to contribute to Failure Detection and Monitoring System development. Results show good agreement with previous studies using other methods as GMDH and other predictive methods. (author)

Rath-Nagel, S.

1981-03-01

Systems analyses were carried out by the International Energy Agency for the participating 15 countries in order to work out strategies and scenarios for lessening the dependence on imported oil and for developing new energy technologies. MARKAL model computations show the technology and energy mixes necessary for achieving a reduction of oil imports by two thirds over the next 40 years. The scenario 'high social security' examines the projected rise in energy consumption, the development of oil substitutes, the increase in alternative heating sources, the development of markets for liquid energy products, the demand for gas, and the relative usage of various energy generation methods. The recommended strategy involves as the most important points an increase in coal consumption, greater nuclear energy reliance and development of alternative technologies.

Energy policies of IEA countries: Luxembourg -- 2008 Review

Energy Technology Data Exchange (ETDEWEB)

NONE

2009-03-20

Luxembourg has reformed its energy policies across all sectors since the last IEA in-depth review in 2004. The country has fully liberalised its electricity and natural gas markets, and is actively participating in the development of the evolving Central West European regional electricity system. Luxembourg has also prepared a broad action plan on energy efficiency, improved the support system for renewable energy sources and revised taxes to mitigate climate change. The country's energy policy in the coming decade will be shaped by the EU 2020 targets that call for substantial reductions in greenhouse gas emissions, and strong increases in renewable energy and energy efficiency. These targets will be hard to meet, given that roughly half of energy-related CO2 emissions come from transport fuel use by foreign truckers and motorists, and that Luxembourg's potential for producing much more renewable energy is limited. Luxembourg is heavily dependent on oil. Although oil sources are well diversified by country of origin, more than 85% of oil stocks are held in neighbouring countries and often based on short-term leasing contracts. This leaves the country vulnerable to potential oil supply disruptions. Luxembourg should swiftly implement a plan to improve the security of oil supply. This review analyses the energy challenges facing Luxembourg and provides critiques and recommendations for further policy improvements. It is intended to help guide the country towards achieving its sustainability targets.

Divided Attention and Processes Underlying Sense of Agency

Directory of Open Access Journals (Sweden)

Wen eWen

Full Text Available Sense of agency refers to the subjective feeling of controlling events through one’s behavior or will. Sense of agency results from matching predictions of one’s own actions with actual feedback regarding the action. Furthermore, when an action involves a cued goal, performance-based inference contributes to sense of agency. That is, if people achieve their goal, they would believe themselves to be in control. Previous studies have shown that both action-effect comparison and performance-based inference contribute to sense of agency; however, the dominance of one process over the other may shift based on task conditions such as the presence or absence of specific goals. In this study, we examined the influence of divided attention on these two processes underlying sense of agency in two conditions. In the experimental task, participants continuously controlled a moving dot for 10 s while maintaining a string of three or seven digits in working memory. We found that when there was no cued goal (no-cued-goal condition, sense of agency was impaired by high cognitive load. Contrastingly, when participants controlled the dot based on a cued goal (cued-goal-directed condition, their sense of agency was lower than in the no-cued-goal condition and was not affected by cognitive load. The results suggest that the action-effect comparison process underlying sense of agency requires attention. On the other hand, the weaker influence of divided attention in the cued-goal-directed condition could be attributed to the dominance of performance-based inference, which is probably automatic.

Heat storage is essential for the reconciliation of heat supply and demand. The earth has already proved to be an excellent medium for storing large amounts of heat over longer periods of time, for instance during the cold and hot season. The efficiency of the storage is the better the lower storage losses are at high temperature levels. Unfortunately this can not be easily achieved. While thermal underground stores, which are widely used for cold storage, have proved to perform quite well at temperatures between 10 C - 40 C, it has been rather difficult to achieve similar results at higher temperatures up to 150 C as test and demonstration plants of the 1980s proved. This issue has again attracted so much interest that the IEA launched a project on high temperature underground storage in December 1998. (orig.) [Deutsch] Waermespeicherung ist von entscheidender Bedeutung, wenn es darum geht, ein Waermeangebot mit einer Waermenachfrage zeitlich zur Deckung zu bringen. Der Untergrund hat sich schon seit vielen Jahren als ein geeignetes Medium erwiesen, groessere Waermepumpen ueber laengere Zeitraeume wie etwa die kalten und warmen Jahreszeiten zu speichern. Die Effizienz eines solchen Speichers steigt mit der Hoehe des erreichten Temperaturniveaus und mit sinkenden Speicherverlusten, was leider eher gegenlaeufige Erscheinungen sind. Waehrend thermische Untergrundspeicher im Temperaturbereich von 10-40 C inzwischen erfolgreich demonstriert wurden und vor allem zur Kaeltespeicherung auch bereits vielfach eingesetzt werden, haben hoehere Temperaturen bis etwa 150 C in den Versuchs- und Demonstrationsanlagen der 80er Jahre vielfaeltige Probleme bereitet. Im Gefolge eines erneuten Interesses an unterirdischer thermischer Energiespeicherung wurde im Dezember 1997 ein Vorhaben des IEA Energiespeicherprogramms zu Untergrund-Waermespeichern hoeherer Temperatur eingerichtet.

Development of methodology for characterization of cartridge filters from the IEA-R1 using the Monte Carlo method; Desenvolvimento de uma metodologia para caracterizacao do filtro cuno do reator IEA-R1 utilizando o Metodo Monte Carlo

The Cuno filter is part of the water processing circuit of the IEA-R1 reactor and, when saturated, it is replaced and becomes a radioactive waste, which must be managed. In this work, the primary characterization of the Cuno filter of the IEA-R1 nuclear reactor at IPEN was carried out using gamma spectrometry associated with the Monte Carlo method. The gamma spectrometry was performed using a hyperpure germanium detector (HPGe). The germanium crystal represents the detection active volume of the HPGe detector, which has a region called dead layer or inactive layer. It has been reported in the literature a difference between the theoretical and experimental values when obtaining the efficiency curve of these detectors. In this study we used the MCNP-4C code to obtain the detector calibration efficiency for the geometry of the Cuno filter, and the influence of the dead layer and the effect of sum in cascade at the HPGe detector were studied. The correction of the dead layer values were made by varying the thickness and the radius of the germanium crystal. The detector has 75.83 cm{sup 3} of active volume of detection, according to information provided by the manufacturer. Nevertheless, the results showed that the actual value of active volume is less than the one specified, where the dead layer represents 16% of the total volume of the crystal. A Cuno filter analysis by gamma spectrometry has enabled identifying energy peaks. Using these peaks, three radionuclides were identified in the filter: {sup 108m}Ag, {sup 110m}Ag and {sup 60}Co. From the calibration efficiency obtained by the Monte Carlo method, the value of activity estimated for these radionuclides is in the order of MBq. (author)

Heavy-duty vehicles in Europe and North America will require incylinder measures or exhaust gas after-treatment technology to control emissions and meet ever stringent emission requirements. Alternatively, manufacturers can choose clean burning alternative fuels such as natural gas. Although there are no international standards for heavy-duty vehicle chassis dynamometer testing at present, the IEA Implementing Agreements offer excellent platforms for international collaborative research. Harmonization of test methods for vehicles and fuels is one important task. This paper reported on the work of 3 laboratories that have produced emission results for complete heavy-duty vehicles. VTT Technical Research of Finland, Environment Canada and West Virginia University measured standard size urban buses driving various duty cycles on chassis dynamometers. The number of transient test cycles per laboratory varied from 6 to 16. European and North American diesel and natural gas vehicles were included in the vehicle matrix. The objective was to demonstrate how the driving cycle affects the emission performance of conventional and advanced urban buses. Several driving cycles were run on urban buses to better understand the characteristics of different duty cycles; produce a key for cross-interpretation of emission results generated with different cycles; and study the interaction between vehicle, exhaust after-treatment and fuel technologies and test procedures. Fuel consumption and exhaust emissions were measured. The results varied significantly not only by test cycle, but also by vehicle technology. In general, vehicles emissions were directly proportioned to the amount of fuel consumed, with the exception of NOx-emissions from SCR-vehicles. There was a clear difference in the emission profiles of European and North American vehicles. In Europe, fuel efficiency was emphasized, while in North America, more focus was given to regulated exhaust emissions, especially low

A three-dimensional distribution of the neutron flux in IEA-R1 reactor, obtained by activating gold foils, is presented. The foils of diameter 8mm and thickness 0,013mm were mounted on lucite plates and located between the fuel element plates. Foil activities were measured using a 3x3 inches Nal(Tl) scintilation detector calibrated against a 4πβγ coincidence detector. Foil positions were chosen to minimize the errors of measurement; the overall estimated error on the measured flux is 5%. (Author) [pt
