The advantages of LH 2 storage lies in its high volumetric storage density (>60 g/L at 1 bar). However, the very high energy requirement of the current hydrogen liquefaction process and high rate of hydrogen loss due to boil-off (∼1–5%) pose two critical challenges for the commercialization of LH 2 storage technology.

Compressed air and hydrogen energy storage hybridized with solar energy to supply electricity and hot water for a residential settlement. Xiang Li, M. Siavashi. Published
The operation of a conventional compressed air energy storage system is described as follows: excess electricity during off-peak hours is used to drive a 2-stage compressor with intercooling. After the compression, the compressed air (40–70 bar) is led to an after-cooler before it gets stored in an underground storage reservoir.
