HORIZON-CL5-2027-07-D3-27
Scope. Projects should demonstrate innovative or improved energy storage technologies that can be integrated into existing, obsolete or underused infrastructure. Solutions should increase energy storage capacity and efficiency, improve electricity grid flexibility and energy security, and reduce the costs and environmental impacts associated with building new facilities. Suitable locations may include former hydropower dams and reservoirs, decommissioned power plants, industrial sites, coal mines and existing fossil-fuel infrastructure. Projects should assess technical feasibility, economic viability, circularity, environmental impacts and socioeconomic benefits, engage relevant stakeholders, and incorporate security-by-design principles.
Sectors. Energy storage, renewable energy, electricity grids, hydropower, industrial infrastructure, circular economy and energy efficiency.
Eligible applicants Legal entity (including from Türkiye).
Key requirements. Projects should demonstrate cost-effective and sustainable storage solutions, reuse existing infrastructure, assess environmental and socioeconomic impacts, apply security-by-design principles and contribute to the BRIDGE initiative. Projects are expected to reach Technology Readiness Levels (TRL) 6–8.
Funding & duration. Funding rate up to 100% under Horizon Europe rules. Total indicative budget: EUR 22.5 million. Expected EU contribution: approximately EUR 7.5 million per project, with three projects expected to be funded. Action type: Innovation Action (IA).
