Abstract:
This invention relates to hydrogen production using combined heat pumps and a thermochemical cycle. Low grade waste heat can be upgraded to higher temperatures via salt/ammonia and/or MgO/vapor chemical heat pumps, which release heat at successively higher temperatures through exothermic reactions, or vapor compression heat pumps that upgrade thermal energy with phase change fluids. Using this new approach, low grade heat or waste heat from nuclear or other industrial sources can be transformed to a useful energy supply for thermochemical hydrogen production.
