In order to meet GB''s needs in 2050, construction of large hydrogen stores must begin in the near future. There is also a need for large-scale demonstrations of other storage technologies. If the incentives that will be required to catalyse the necessary investments are not in place soon, GB will not have the storage that will be required when it is needed.

In the process of building a new power system with new energy sources as the mainstay, wind power and photovoltaic energy enter the multiplication stage with randomness and uncertainty, and the foundation and support role of large-scale long-time energy storage is highlighted. Considering the advantages of hydrogen energy storage
Hence, a simple reactor design with reasonably higher reaction rates for medium to large-scale hydrogen storage applications must be developed. In this perspective, an annular MH bed that is cooled/ heated on both the inner and outer surfaces is designed, fabricated and experimented.
Pure hydrogen can be stored as a liquid and gas in many ways. These are physical, chemical and adsorption methods (Andersson and Grönkvist 2019 ). Physical methods; pressure can be stored in large steel tanks and underground geological structures. These structures include depleted oil and gas aquifers and salt caverns.
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.
The large-scale storage of hydrogen plays a fundamental role in a potential future hydrogen economy. Although the storage of gaseous hydrogen in salt caverns already is used on a full industrial
