“…This is equivalent to 30 weeks' output from a large offshore wind farm which is far more than is needed to eliminate the intermittency issues associated with such a facility. Hence, it was proved that only a few offshore gas fields are required to store enough energy as hydrogen to balance the entire seasonal demand for UK domestic heating (Mouli-Castillo et al 2021).…”

Dihydrogen (H2), commonly named ‘hydrogen’, is increasingly recognised as a clean and reliable energy vector for decarbonisation and defossilisation by various sectors. The global hydrogen demand is projected to increase from 70 million tonnes in 2019 to 120 million tonnes by 2024. Hydrogen development should also meet the seventh goal of ‘affordable and clean energy’ of the United Nations. Here we review hydrogen production and life cycle analysis, hydrogen geological storage and hydrogen utilisation. Hydrogen is produced by water electrolysis, steam methane reforming, methane pyrolysis and coal gasification. We compare the environmental impact of hydrogen production routes by life cycle analysis. Hydrogen is used in power systems, transportation, hydrocarbon and ammonia production, and metallugical industries. Overall, combining electrolysis-generated hydrogen with hydrogen storage in underground porous media such as geological reservoirs and salt caverns is well suited for shifting excess off-peak energy to meet dispatchable on-peak demand.

“…This is within reasonable distance of Yorkshire salt deposits as can be seen in Figure 8a and thus will depend on functional purpose and economic factors. In the recent publication by Mouli-Costillo et al, offshore gas reservoirs off the coast of the UK were mapped and assessed for hydrogen storage [85]. Mouli-Costillo et al calculates through a box conversion a potential 2661.9TWh of hydrogen could be stored off the coast of the UK [85].…”

It is further suggested that aquifers in this region could potentially surpass this is capacity; however, measuring such is made difficult through unavailable information [85].…”

“…The storage of surplus electrical energy could increase the utility of renewable energy sources thereby reducing the environmental impact of energy generation 1,2 . Storage mediums like batteries, compressed air, capacitors, or flywheels are only applicable for the short-term and small-scale electricity storage 3 . The use of hydrogen (H2) as an energy vector however could provide long-term storage to balance the intermittent demand and supply challenges affecting renewable methods 3 .…”

Considering the low energy density of H2 4 , storage of H2 in large storage sites is the only solution for economical, gigawatt to terawatt-scale H2 storage.…”

Hydrogen can act as an energy store to balance supply and demand in the renewable energy sector. Hydrogen storage in subsurface porous media could deliver high storage capacities but the volume of recoverable hydrogen is unknown. We imaged the displacement and capillary trapping of hydrogen by brine in a Clashach sandstone cylinder at 2-7 MPa pore fluid pressure using X-ray computed microtomography. Hydrogen saturation obtained during drainage at capillary numbers of <10-7 was ~50% of the pore volume and independent of the injection pressure. Fluid configuration in the pore space was indicative of a water wetting system at all conditions. Capillary trapping of hydrogen via snap-off during secondary imbibition at a capillary number of 2.4x10-6 systematically increased with pressure, 20%, 24% and 43% of the initial hydrogen trapped at 2, 5 and 7 MPa, respectively. Injection of brine at increasing capillary numbers up to 9.4x10-6 reduced capillary trapping. Based on these results, we recommend more shallow, lower pressure sites for future hydrogen storage operations in porous media.
