Storing green electricity under the sea.

The aim of H2-O is to compensate for the intermittent nature of renewable energy sources by storing and producing green electricity from green hydrogen.
Surplus renewable energies such as wind, photovoltaic or even nuclear power, in the meantime, will be converted into green hydrogen through a pressurized seawater electrolyser immersed at great depths.
The green hydrogen released will then be stored in very large-capacity tanks, themselves immersed in the immediate vicinity of the electrolyzer.
This stored hydrogen, under pressure under seawater, in very cheap concrete tanks will then be transformed locally into green electricity via a fuel cell or a hydrogen turbine coupled to a generator.
The green electricity thus produced will be redistributed via the same network according to needs and peak hours.
