Underground hydrogen storage: a review
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 a …
