| Abstract: | Hydrogen (H₂), an environmentally clean energy-carrier gas, is produced mainly from fossil fuel, biomass and water.
H2 (90%) is produced at high temperature by the reactions of natural gas or light oil fractions with steam, besides coal
gasification and electrolysis of water. Among biological production of H₂, direct and indirect biophotolysis, fermentation,
photosynthetic production and in vitro enzymatic conversion of biomass are important. H₂ is a substance with high energy
content compared to its weight, however, energy content compared to volume is rather low. This poses challenges with
respect to storage compared to storage of gasoline, a liquid. Current H₂ storage approaches involve compressed H₂ gas
tanks, liquid H₂ tanks, metal hydrides, carbon-based materials/high surface area sorbents, and chemical H₂ storage. This
paper reviews various production and storage strategies of H₂. |
