WebAmmonia borane, with a hydrogen content of 19.6% by weight, is a promising hydrogen storage material – with the major drawback that hydrogen release is irreversible. ‘Despite the common thinking those materials will never reversibly store hydrogen, we can generate a compound that can reversibly store hydrogen,’ he says. WebHydrogen. Bengt Sundén, in Hydrogen, Batteries and Fuel Cells, 2024. 3.4.3.2 Compressed cryogenic gas. Cooling down compressed hydrogen gas means increasing the density and more stored gas in the tank. The system is often cooled down to 77 K with liquid nitrogen, increasing the volumetric capacity by three times compared to non-cooled …
