Reliable renewable power for hydrogen and clean fuel production

Producing green hydrogen and synthetic clean fuels requires stable and continuous power, while renewable electricity is inherently variable. The costs of renewable energy contribute for approximately 65% to the LCOH (Levelized Cost Of Hydrogen), intermittency is one of the root causes.

Elestor’s hydrogen-iron flow battery addresses intermittency by delivering long-duration energy storage that stabilizes renewable power, enables economically viable hydrogen production, and supports efficient operation of electrolysers and downstream clean fuel production plants.

A hydrogen-iron flow battery replaces the traditional set-up using short-term batteries and a hydrogen storage. Elestor's battery enables low-cost buffering of electricity, making it possible to run the electrolyser on par with a downstream clean fuel plant. With cost-effective storage durations of 15–30 hours in this application, more renewable energy can be utilized while maintaining stable plant operation.

During periods of low renewable generation, the battery acts as a resilience buffer, allowing electrolysers and fuel synthesis plants to continue operating stable capacity instead of shutting down.
