On Methods for the Large-Scale Production of Hydrogen from Water

  • J. O’M. Bockris


Off-peak power would give sufficiently cheap hydrogen with classical electrolyzers. Emerging technology could produce it at between $0.85 and $2.90 (106 Btu)-1 for electricity costs (bulk purchase) between 2 and 7 mils. High temperature electrolyzers are less advantageous than thermal assisted electrolysis of cuprous chloride ($2.08). Photoelectrochemical methods project costs at less than $0.70; photosynthetic at $0.40. Research stress should be on: use of off-peak power, cuprous chloride electrolysis, photo-oriented methods. The latter could offer hydrogen cheaper than from present natural gas.
