1. CEA/DRT/DTEN/SCSE/GENECCIRED 2003 Barcelona May13th N°1999/12442c INVESTIRE Investigation on Storage Technologies for Intermittent Renewable Energies Power supply Load profile Increased value of energy higher buy-back rates for predictable energy sources Increased penetration of RES store power when in excess for later use

2. CEA/DRT/DTEN/SCSE/GENECCIRED 2003 Barcelona May13th N°1999/12442c INVESTIRE Description of the project  Thematic network ( data gathering but no R&D work )  33 Partners  0.8 M€  30 month duration (finished in October 2003)  9 technologies addressed Lead-acid batteries Lithium batteries Double layer capacitors Nickel based batteries Electrolyser, H 2 storage, fuel cell Flywheels Redox-flow batteries Compressed air Metal/air batteries

3. CEA/DRT/DTEN/SCSE/GENECCIRED 2003 Barcelona May13th N°1999/12442c INVESTIRE Objectives  To propose technology neutral evaluation criteria that are suited for the renewables applications  Technical ( lifetime, energy efficiency, self discharge …)  Economical (investment cost, operating cost, cost of delivered kWh …)  Environmental (use of scarce resources, recycling …)  To determine the needs in R&D  Based on the various applications  For each storage technology  For the storage systems (possible hybridation …)

4. CEA/DRT/DTEN/SCSE/GENECCIRED 2003 Barcelona May13th N°1999/12442c INVESTIRE Technical criteria  Requirements on the storage function based on questionnaires about existing and future applications ( mostly stand-alone )  Clustering is technology neutral

5. CEA/DRT/DTEN/SCSE/GENECCIRED 2003 Barcelona May13th N°1999/12442c INVESTIRE Self discharge  Large dispersion of the self discharge values  Technologies decoupling power and energy are suited for long term storage

6. CEA/DRT/DTEN/SCSE/GENECCIRED 2003 Barcelona May13th N°1999/12442c INVESTIRE Energy efficiency –Large dispersion of the energy efficiency values –Low efficiency technologies suited only for seasonal storage in stand-alone applications

7. CEA/DRT/DTEN/SCSE/GENECCIRED 2003 Barcelona May13th N°1999/12442c INVESTIRE Economics  Investment cost of the only installed technology ( no periphery )

8. CEA/DRT/DTEN/SCSE/GENECCIRED 2003 Barcelona May13th N°1999/12442c INVESTIRE Further work and Conclusions  Further work:  Finalisation of publishable technology reports  Transversal analysis and further data gathering  Definition of an R&D roadmap  Finalisation of a mapping of centres of excellence  Information on www.investire-network.com  Conclusions:  INVESTIRE allows the gathering of manufacturers, research structures and professional associations  Lack of validated data for emerging technologies
