Energy storage is facing an impressive growth mainly coming from renewable energy sources. Sun and wind do not always provide electricity when it is needed the most (peak periods). Electricity has then to wait for its consumption. Transforming the excess of electricity into hydrogen makes electricity easy to store for both long and short term period. McPhy has decided to focus on this opportunity and comes up on the market with a highly innovative energy storage system. On the other hand, hydrogen consumers need safe hydrogen storage, 300 bar pressure vessels and liquid hydrogen are in most cases issues. Metal hydrides allow low-pressure storage and are a solution for industries, which require safety hydrogen storage. While coupling hydrogen produce with water electrolysis from renewable energy and McPhy storage system, it brings today on the market breakthrough “green” hydrogen. Thus C02 emissions from hydrogen production can be heavily lowered.
