Carbonate Thermochemical Cycle for the Production of Hydrogen

The subject invention disclosed herein is a new process for producing hydrogen at a much lower temperature (375°C) than that reported in the currently used sulfur-iodine process. The present invention avoids the use of electrolysis and employs no toxic gases. Since the process of the subject invention has a peak temperature (760°C) that matches temperatures of current (gas-cooled) nuclear reactors under serious consideration for construction in the U.S., the development of radical new reactors concepts and designs may not be necessary for the process of the present invention. The present invention could largely displace carbon-based fuels (e.g. gasoline) within the world economy.
