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


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, H2 storage, fuel cell

Flywheels

Redox-flow batteries

Compressed air

Metal/air batteries


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 …)


INVESTIRE Technical criteria

Requirements on the storage function based on questionnaires about existing and future applications (mostly stand-alone)

Clustering is technology neutral

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
