Abstract
A system including: a pumped-heat energy storage system ('PHES system'), wherein the PHES system is operable in a charge mode to convert electricity into stored thermal energy, wherein the PHES system comprises a working fluid path circulating a working fluid through, in sequence, at least a compressor system, a hot-side heat exchanger system, a turbine system, a cold-side heat exchanger system, and back to the compressor system; and (ii) a fluid path directing a hot fluid from a heat source external to the PHES system through a reheater, wherein a portion of the working fluid path through the turbine system comprises circulating the working fluid through a first turbine, the reheater, and a second turbine, and wherein the working fluid thermally contacts the hot fluid in the reheater, thereby transferring heat from the hot fluid to the working fluid.
