Cost-effective next-generation batteries for long-duration stationary storage
Funds research into next-generation battery chemistries for long-duration and seasonal stationary energy storage, at costs below 50 euros per kWh.
Proposals must show a credible path to an energy storage system costing under 50 euros per kilowatt-hour, a projected 20-year lifetime with minimal self-discharge, and a round-trip efficiency of at least 50% at system level and 75% at cell level, while working on chemistries that currently sit at a low technology readiness level rather than incremental tweaks to what's already commercial. Dependin…
The call wants research into low-Technology-Readiness-Level battery materials for storage durations from 10 hours to seasonal storage, aiming for energy storage system cost below EUR 50/kWh, a 20-year lifetime, and minimum round-trip efficiency of 50% at system level. Lithium-ion, vanadium redox flow, sodium-ion with liquid electrolyte and molten sodium-sulphur are explicitly excluded as already-commercialised technologies.
