Hydrogen gas is supplied directly from H2 generator to power plant.
Extra gas production should be stored at high pressure in pressure vessels which are 2 types:
1-Fixed type named as Modular sieve.
2-Mobile type referred to as H2 racks.
Usually both types exist in power plants.
The mobile type will serve the same as the fixed one but they have the advantage of possible filling outside the power station in emergency case when the generator is not working properly.
The hydrogen compressor will allow storage of H2 at 165 bar or 200 bar according to design required.
