The IEA provides support for international collaboration on energy technology R&D, deployment and information dissemination. These groups function within a framework created by the IEA - the International Framework for International Energy Technology Collaboration. The views, findings and publications of these international groups (formally called Implementing Agreements) do not necessarily represent the views or policies of the IEA Secretariat or of all its individual member countries. OECD Member countries, autonomous OECD non-member countries, intergovernmental organisations, non-governmental organisations and private sector entities may participate. For more information, see our Technology Agreements page.

Industrial Energy-Related Technologies and Systems

The IETS program focuses on energy use in a broad range of industry sectors, uniting IEA activities in this area. The program was established in 2005 as a result of a merger, revamping and extension of activities formerly carried out by separate individual programs. The former programs for Pulp & Paper and for Process Integration are now parts of the IETS. The new program is still under development, with several new activities starting up. The objective of IETS is to allow OECD Member countries and OECD non-Member countries to work together to foster international co-operation for accelerated research and technology development of industrial energy-related technologies and systems with main focus on end-use technologies, also taking into account other relevant IEA activities. Through its activities, the program will increase awareness of technology and energy efficiency in industry, contribute to synergy between different systems and technologies, and enhance international cooperation related to sustainable development. The participants will implement a wide range of co-operative activities in the fields of:

- Scientific research;

- Technology and systems research, development, demonstration and deployment;

- Technology and systems foresighting;

- Technology and systems assessment of policies and consequences;

- Information dissemination.

Current Projects (Annexes)

09. Energy Efficient Separations Systems: Methodological Aspects, Demonstration and Economics
The goal of the annex is to take stock of the state-of-the-art of separation systems analysis tools and concepts and: 1. Extend/combine previously developed methods and tools to address advanced separation systems design or retrofits 2. Automate or guide the design/retrofit process to the extent practicable 3. Quantify and improve the costs and benefits of these approaches. The Separation Systems annex is concerned with processes that use one or more forms of energy such as thermal, chemical or electrical to isolate and/or recombine selected constituents from an initial ensemble of materials or mixtures to produce a useful and improved end-product with an acceptable environmental footprint. More precisely it is concerned with the "systems" aspects of these separation activities. Since 2007 the participants of the annex have been working to enable effective and practical design/retrofit of separations systems. By the end of the project period, in January 2011, hopefully the annex will have succeeded in defining what is an optimal combination of physical/mathematical/engineering concepts and tools that will effectively guide the search for an appropriate separation system given an initial set of requirements.


11. Industry-Based Biorefineries
The general objective for this Annex is to provide a sound basis for the efficient integration of biorefinery concept in different industrial sectors where biomass is used as resource or biomass based waste is available, which could be used for fuel/energy production, also considering opportunities of bio-products generation with added value. The work to be developed has a technology component as well as a systems approach. Areas for international cooperation: Exchange of information on the optimization of energy efficiency in existing plants, to convert internal biomass and black liquor to energy and bioproducts Implementation of joint projects leading to engine fuels production connected to a pulp or pulp and paper mill R&D connected to pulp mill biorefineries to produce new materials and chemicals R&D associated to the integration of CO2 capture and sequestration at lower costs The scope of Annex XI is the integration of biorefinery concept in industry, integrating with an existing plant (e.g. pulp and paper mill) or other, either individual or a complex of industrial companies. It includes economic evaluation, energy efficiency and technical integration of processes that provide energy and higher value-added products.


12. Membrane Technologies
From both the technological and application points of view, separation technology is a very broad field. Molecular membrane separation (a membrane is a partically selective barrier for transport of matter) is seen as one of the most promising and energy-efficeint separation technologies. In practice a reduction of 40-60% of primary energy consumption is anticipated in key molecular separation. Task 12.1 Membranes as energy-efficient technologies for Separation of Hydrocarbons The urge for energy efficient separation technology highlights the need for dissemination of results from different research areas and different countries. Regular assessments of R&D priorities and gaps, as well as comparatie analysis of individual technologies are important to identifying the barriers that hamper implementation of these technologies. The task arims to be a facilitating platform for these activities. Objectives of the task: 1. The organisation of a discussion platform for the dissemination of results in membrane separation. To enhance focus and prioirites in the field of energy efficient membrane separations, road mapping exercises will be stimulated. This will lead to technology assessments and initial estimates of energy savings potential. 2. Oordination of research efforts. Based on an initial screening, olefin/paraffin separation and natural gas and biogas production were selected as focal point for this platform. The task is divided into three subtasks: Subtask A: Road mapping and focussing activities Subtaks B: Natural gas and biogas production Subtask C: Olefin/paraffin separation


13. Industrial Heat Pumps
The objective of this Annex is to reduce the use of energy and emissions of greenhouse gases by the increased implementation of heat pumps in industry, by: - generating information for policy makers - developing information for key stake holders in industry and its supply consulting chain and for policy makers - getting insight in business decision processes - increasing the knowledge and information about IHP's database and getting existing information available - applying new technologies and identifying the needs for technological development - creating a network of experts - finding a synergy with renewable energy production to increase flexibility of the grid The objectives will be achieved by common studies performed by the participants for each country. The main focus of the Annex will be on arranging the information on heat pumping technologies for industry in such a away that it will lead to better understanding of the opportunities and using these in the right way in order to reduce the use of primary energy consumption and the CO2 emissions as well as energy costs. The Annex commenced 1 January 2010 and will remain in force until December 2012.


14. Process integration in the Iron and Steel Industry
The objectives of this Annex are to reduce the use of energy and greenhouse gas emissions in the iron and steel industry by: - creation of a network of experts involved in projects with the iron and steel industry and the use of Process Integration methods as a common denominator; - Bringing together and sharing information on the present state of the art of methods as well as practical tools for systems optimisation with regard to energy and GHG emissions; and - Creation of guidelines for the application of Process Integration methods in the industry.


15. Industrial Excess Heat Recovery
This Annex will share information on state-of-the-art and emerging technologies on utilisation of excess heat that is available in the industry and identify technological and non-technological barriers (risk, economies of scale, decision maker not exposed to the technology). The Annex will also work on reducing process energy usage (specific energy consumption/energy intensity) and list gaps (possible failures due to non-availability in suppliers) in the form of case studies.


16. Energy Efficiency in SMEs
This Annex will be broken down into four Tasks: 1. Energy policies and programs towards industrial SMEs; 2. Energy efficiency technologies and their potentials and barriers to implementation in industrial SMEs; 3. Methods and tools to achieve energy efficiency in industrial SMEs; 4. Energy services towards industrial SMEs.
