Project description

Innovative seasonal energy storage system on the path to commercialisation

The aim of the EU-funded Powerbox project is to commercialise the innovative energy storage solution developed by Solenco. Solenco Powerbox allows homes and businesses to cheaply store their own generated energy, for hours or whole seasons, with over 90 % conversion efficiency. The system combines an electrolyser and a fuel cell in one unit which transform electricity into hydrogen, store it indefinitely and then convert hydrogen back into electricity and heat with minimal losses. Heat output takes the form of hot water at a rated temperature of 80 °C. The system has zero-carbon footprint and works anywhere, allowing homes and businesses to be heated and powered with intermittent energy sources and even feed excess power into city grids.
