METHOD AND APPARATUS FOR PROVIDING PRESSURIZED HYDROGEN GAS

摘要

Apparatus and process for producing hydrogen gas at a desired pressure comprising feeding a hydrogen gas at a first temperature and first pressure from a hydrogen source to heat transfer means comprising cooling means and heating means; cooling the hydrogen gas with the cooling means to provide cooled hydrogen gas; feeding the cooled hydrogen gas to a metal hydride generator containing the metal; forming the metal hydride within the generator; heating the formed metal hydride to a temperature Tp and desired pressure; and releasing the pressurized hydrogen gas at the desired pressure from the generator and producing regenerated metal. Preferably, the apparatus comprises a plurality of generators linked to the heat transfer means to allow for continuous usage of both cooled hydrogen gas and generated heat from the heat transfer means to collectively provide a continuous pressurized hydrogen gas product supply.
