“…It concluded that hydrogen was the most environmentally efficient fuel with global warming potential as 0.04 kg CO 2 eq/kWh Siddiqui and Dincer, 2019 The water electrolysis route, coal gasification and biomass gasification routes showed global warming potential of 28.6, 23.7 and 4.4 kgCO 2 eq/kg H 2 , respectively. In addition to this, the ethanol, methanol and methanebased hydrogen production routes are estimated to have 12.2, 17.9 and 13.8 kgCO 2 eq/kg H 2 of global warming potential, respectively Valente et al, 2019 In terms of global warming potential, biomass hydrogen was a better option than conventional hydrogen, however, to a lesser extent for acidification potential Karaca et al, 2020 Nuclear-based hydrogen production methods caused global warming potential from 0.48 to 0.71 kgCO 2 eq/kg H 2 high specific energy and non-CO 2 emission after combustion. The challenge is to find hydrogen storage materials with high capacity.…”

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.

“…The difference from conventional electrolysis to nuclear high temperature electrolysis (HTE), is that the later uses heat from nuclear power plants to moderate electricity consumed for electrolysis. In general, nuclear HTE occurs at 800-1000 o C and an yttria-stabilised zirconia is used as an electrolyte [41]. A solar-based electrolysis consists of a concentrating collector, a heat engine, an electrical generator, and electrolyser.…”
