Hydrogen production using inorganic membrane reactors

Current hydrogen production processes, which depend upon the use of fossil fuels, are discussed. The means which can be used to increase efficiency, and to enable both up-and down-scaling, are considered, in particular the use of catalysts and inorganic membranes. Biomass as an alternative energy source for the production of biohydrogen through both aerobic and anaerobic fermentation has the potential to make hydrogen a truly environmentally friendly fuel.
