A zero-emission process of hydrogen production from fossil fuel through a system of reactions involving hydroxide, carbon, CO, CO2 and water is described here. it provides for a complete sequestration of carbon (CO2 and CO) from coal/natural-gas burning plants, The CO and or CO2 produced in coal or natural gas burning power plants and the heat may be used for producing hydrogen. Economically hydrogen production cost is less than the current price of fossil-fuel produced hydrogen with the added benefit of carbon sequestration. The reduced cost of the hydrogen may aid in making a hydrogen fueled automobile economically viable. (C) 2008 International Association for Hydrogen Energy. Published by Elsevier Ltd.
