- Single-stage application, due by the deadline below.
This Horizon Europe Cluster 5 topic funds system-level demonstration of long-duration electricity storage technologies — over 8 hours of discharge — that are not yet on the market, such as flow batteries, high-temperature systems, metal-air and multivalent chemistries. Projects are expected to use abundant, low-cost materials with European supply chains, cutting reliance on critical raw materials. The scope also requires a full techno-economic analysis (CAPEX/OPEX) and a system-level safety assessment. The budget is €9.4 million per project, with 2 projects expected, for €18.8 million in total. The expected outcome by project end is TRL 6 to 7.
