Presented at: STORE 2003: Storage for Renewable energies, Aix-en-Provence, France, 20-21 oktober 2003.


For evaluating energy storage technologies, economical parameters are of considerable importance. A qualitative assessment is given of storage technologies in general, contributing to success or failure of their use. Based on data of nine storage technologies that are defined in the INVESTIRE Network, results of a quantitative cost analysis are presented, based on device-specific key parameters. The costs have been defined as additional costs, effected by the required investments and operation and maintenance expenditures, the efficiency of a device and its lifetime. In order to compare the technologies properly, categories of typical use have been defined, ranging from stand-alone small applications (typical storage capacity of 0.1 kWh) to levelling of power production (approximately 1 MWh). The outcome is presented in such a way that for each category of typical use, the best technological options are identified, based on a cost analysis.
