Hydrogen storage

Hydrogen is nowadays stored under the pressure of 200–250 bar in 50-L cylindrical tanks. However, the storage pressure as the gas can able to increase up to 600–700 bar. The volumetric energy density of the hydrogen is low due to the nature of being very light even if it is stored in the 50 L tank.
