Demonstration for Long-duration Battery Energy Storage Systems (BATT4EU Partnership)
European Commission · Horizon Europe Framework Programme (HORIZON)
Posted 5 May 2027 · About 12 months left
Summary
Expected Outcome:
Projects are expected to contribute to all of the following outcomes:
Demonstrated system-level long-duration energy storage (LDES) solutions, explicitly aimed at enhancing grid stability, resilience, and flexibility in Europe.
Substantial reduction of Europe's dependence on critical raw materials through the use of abundant, low-cost, and sustainable materials.
Contribute to strategic insights for a coherent EU-wide stationary storage deployment strategy, enhancing European energy autonomy and sustainability.
Sufficient and reproducible operational data and insights to serve as reliable input towards detailed technoeconomic analyses.
Scope:
Proposals should focus on system-level demonstrations of innovative long-duration (> 8 hours) battery storage concepts that can effectively support utility-scale energy systems or industrial consumers in achieving energy security and operational sustainability.
Projects are expected to cover all the following points:
Demonstration of advanced long-duration storage technologies not yet on the market such as novel redox flow batteries (standard or mediated), high-temperature systems, metal-air systems, multivalent chemistries…
