Certain Energy Raises €11.6M for Flow Batteries
Certain Energy raised €11.6M to commercialise manganese flow batteries for long-duration grid storage.
Long-duration storage remains one of the key missing pieces for a more flexible electricity grid.
What happened
UK long-duration storage startup Certain Energy, formerly RFC Power, raised €11.6M / £10M Series A to commercialise manganese flow battery technology for grid-scale deployment.
Why it matters
AI data-centre growth, renewable generation and electrification are all putting more pressure on the grid. Batteries that can store power for longer than a few hours are important for reliability.
Certain Energy is targeting that long-duration storage gap.
The bigger picture
Climate tech and AI infrastructure are increasingly connected. As compute demand grows, grid stability and storage technologies become part of the AI supply chain.
