Germany breaks ground on world’s largest green H₂ storage facility

Hydrogenious is building an 1,800t/yr plant to store green hydrogen using liquid oils and is already eyeing exports to Rotterdam

Construction has started in Germany on the world’s largest project storing green hydrogen using liquid organic hydrogen carriers (LOHC). It is set to start operating in 2023. An industrial site owned by domestic polymer producer Covestro in Dormagen, in Germany’s western state of North Rhine-Westphalia, will become home to a plant capable of storing around 1,800t of green hydrogen a year using benzyltoluene as an LOHC medium, says Hydrogenious LOHC Technologies, the company leading the project. LOHC technology is widely seen as an efficient way to store and transport hydrogen. Liquid oils have high storage density, do not require extreme cooling or heating conditions and are barely flammable
