Scope

This Horizon Innovation Action supports system-level demonstrations of innovative long-duration battery storage (more than 8 hours) for utility-scale energy systems or industrial consumers.

Expected activities

• Demonstrate advanced long-duration storage technologies not yet on the market, such as novel redox flow, high-temperature, metal-air or multivalent chemistries.
• Define use cases (grid-scale storage, large industrial consumers, firming of renewable generation) with quantified impact on resilience, emissions, safety and storage cost.
• Assess hybridisation with complementary storage technologies.
• Use abundant, low-cost, sustainable materials with reliable European supply chains, and show pathways to large-scale production.
• Integrate digital tools for state-of-charge, state-of-health and lifetime prediction and for battery and energy management.
• Carry out techno-economic analyses based on measured performance and a system-level safety assessment, with Safe and Sustainable by Design as a reference.

Expected outcomes

Demonstrated long-duration storage that improves grid stability and flexibility, less dependence on critical raw materials, input for an EU-wide stationary storage strategy, and reliable operational data for techno-economic analysis. Exploitation plans should include scalability, commercialisation and deployment, indicating possible funding sources such as the Innovation Fund. Activities are expected to reach TRL 6-7 by the end of the project.

Qu’attend-on des propositions ?

• Projects are expected to cover all listed points, including demonstration of technologies not yet on the market.
• Funded projects are expected to report results to the Batt4EU partnership.
