Abstract

The disclosure provides a system and method for absorbing clean heat, storing it at ambient temperature for transport or delayed use, and regenerating with high exergetic efficiency. The system and method can capture high quality heat at high temperatures from a source such as nuclear, concentrated sunlight, or geothermal, store that energy in chemical bonds at ambient temperature, and regenerate the heat at the same or similar temperatures. By storing at ambient temperature, the process allows heat to be transmitted over great distances or held long term with minimal losses. The chemical reaction uses the Boudouard reaction with metal carbonate and catalyst to generate a higher heat than a typical Boudouard reaction. The sensible heat that is lost in conventional steam piping by heat transfer to the environment can be reduced or replaced with the present invention that transports chemical heat at ambient temperatures with little sensible heat loss.
