Abstract

An apparatus for a method using hydrogen-occluded alloy for recovering power from waste heat includes first and second heat exchangers containing hydrogen-occluded alloy, a first selector valve for alternating introduction of waste heat fluid between the first and second heat exchangers, a second selector valve for alternating introduction of cooling fluid between the first and second heat exchangers, a turbine associated with the heat exchangers, and a power generator connected to the turbine. The hydrogen-occluded alloy in the first and second heat exchangers is in the form of a multiplicity of stages that release the hydrogen gas at different temperatures, with the hydrogen gas being produced at a prescribed pressure by contact with waste heat fluid.
