The studies showed that the hydrogen withdrawal rate increased with the number of storage cycles while the amount of water extracted declined with each storage cycle [15]. Used the ECLIPSE 100 Solvent Model and conducted numerical simulations of seasonal hydrogen storage in the Norne hydrocarbon field, offshore Norway.

For seasonal storage of renewable energy, large-scale storage of hydrogen is one strategy to help ensure that energy supply can always meet the energy demand. Hydrogen has the highest gravimetric energy density of all known substances (120 kJ g −1 ), but the lowest atomic mass of any substance (1.00784 u) and as such has

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.
