Certain Energy is a UK long-duration energy storage (LDES) company that rebranded in August 2026 from its previous name, RFC Power. Founded in 2017 as a spin-off from Imperial College London, it develops a patented manganese-based flow battery designed for a 20-year operating life, a 75% round-trip efficiency and marginal storage costs targeted at roughly one-tenth those of comparable vanadium flow batteries. The £10 million Series A round in August 2026 will fund a grid-connected MWh-class system in India, an expanded UK research facility and the supply-chain build-out for replicable projects.
