5.5.Eu supported actions for development of Energy Saving Technologies
The main, but not unique European program for development and promotion of Energy Saving Technologies [http://cordis.europa.eu/fp7/energy/home_en.html]. The objective of energy research under FP7 is to aid the creation and establishment of the technologies necessary to adapt the current energy system into a more sustainable, competitive and secure one. It should also depend less on imported fuels and use a diverse mix of energy sources, in particular renewables, energy carriers and non polluting sources.
Growing global demand for energy to power economic development and growth demands the development of cost-effective technologies for a more sustainable energy economy for Europe (and world-wide) to ensure that European industry can compete successfully on the global stage.
The EU Member States and the European Parliament have earmarked a total of € 2.35 billion for funding this theme over the duration of FP7 (2007-2012).
Emphasis is be given to the following activities:
Hydrogen and fuel cells
Renewable electricity generation
Renewable fuel production
Renewables for heating and cooling
CO2 capture and storage technologies for zero emission power generation
Clean Coal Technologies
Smart energy networks
Energy efficiency and savings
Knowledge for energy policy making
Within the frame of FP7 the project calls as well as research topics, and expected impact where defined with the cooperation of DGs of European commission, with participation of technological platforms.
Calls of the FP7 Energy Theme include some 30 topics on renewable energies (PV, CSP, wind energy, bioenergy, solar heating and cooling), CCS, smart electricity networks as well as on energy efficiency. The whole spectrum from fundamental research to applied research and demonstration activities is covered. A special focus is on international cooperation where, for the first time, Marie-Curie-type researchers exchange actions with the US and Japan are supported. The great majority of the FP7 Energy topics are in line with the Implementation Plans of the Industrial Initiatives of the SET-Plan. Energy research is also supported in other FP7 Themes and Programmes. The Technology Roadmaps are a basis for planning and decision-making, and define the European The technology roadmaps serve as a basis for strategic planning and decision making. They have been drawn up by the Commission services from the ongoing work to define the proposed European Industrial Initiatives. This has been a collective endeavour that started in 2008 based on industry proposals, and has advanced through continuous discussions, workshops, multilateral meetings and expert consultations between the Commission services and the European energy technology platforms, the relevant sector associations, the research community, Member States and other stakeholders. In this framework, the information system of the SET-Plan (SETIS) [http://setis.ec.europa.eu/about-setis/technology-roadmap/Complete%20report.pdf/view] has provided valuable data and analysis on the current state of the art of the individual technologies and their anticipated technological development and market potential through its Technology Map; and on the ongoing private and public R&D investments in these technologies through its Capacities Map. Significant steps have been taken to define measurable and suitably ambitious technological objectives and of the required research, development and demonstration activities for each EII. Consultations with the European Community Steering Group on strategic energy technologies have also been initiated via dedicated workshops to agree on the scope and content of each EII and the appropriate implementation methods. Industrial Initiatives (EIIs). These Roadmaps put forward action plans aimed at raising the maturity of technologies to a level that will enable them to achieve large market shares in the period up to 2050.
