INVESTIRE

• Investigation on Storage Technologies for
  Intermittent Renewable Energies

INVESTIRE Description of the project

• Thematic network (data gathering but no RD 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 Electrolys
er, 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 RD
• Based on the various applications
• For each storage technology
• For the storage systems (possible hybridation )

4
INVESTIRE Technical criteria

• Requirements on the storage function based on
  questionnaires about existing and future
  applications (mostly stand-alone)
• Clustering is technology neutral

5
INVESTIRE Self discharge

• Large dispersion of the self discharge values
• Technologies decoupling power and energy are
  suited for long term storage

6
INVESTIRE Energy efficiency

• Large dispersion of the energy efficiency values
• Low efficiency technologies suited only for
  seasonal storage in stand-alone applications

7
INVESTIRE Economics

• Investment cost of the only installed technology
  (no periphery)

8
INVESTIRE Further work and Conclusions

• Further work
• Finalisation of publishable technology reports
• Transversal analysis and further data gathering
• Definition of an RD 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
