Abstract: A method including: (i) operating a pumped-heat energy storage system (“PHES system”) in a charge mode to convert electricity into stored thermal energy in a hot thermal storage medium (“HTS medium”) by transferring heat from a working fluid to a warm HTS medium, resulting in a hot HTS medium, wherein the PHES system is further operable in a generation mode to convert at least a portion of the stored thermal energy into electricity; and (ii) heating the hot HTS medium with an electric heater above a temperature achievable by transferring heat from the working fluid to the warm HTS medium.

Abstract: The present disclosure provides pumped heat energy storage systems that can be used to store and/or extract electrical energy. A pumped heat energy storage system of the present disclosure can store energy by operating as a heat pump, whereby net work input can be used to transfer heat from the cold side to the hot side. A working fluid of the system is capable of efficient heat exchange with heat storage fluids on a hot side of the system and on a cold side of the system. Such pumped energy storage systems can be beneficially integrated with steam plants to provided heating to the steam cycle.

Abstract: The present disclosure provides pumped heat energy storage systems that can be integrated with a Coal Fired Energy Generation Unit (CF-EGU) to repurpose CF-EGUs as thermal energy storage systems. A pumped heat energy storage system of the present disclosure can store thermal energy by operating as a heat pump with heat discharge occurring as a result of heat engine operation of the pumped heat energy storage system and/or a steam cycle of the CF-EGUs to provide heating thereto. For example, thermal energy can be exchanged via working fluids flowing between the pumped heat energy storage systems and the CF-EGUs to drive turbines that provide power to generators while repurposing equipment from the CF-EGUs to create energy.

Abstract: The present disclosure provides pumped thermal energy storage systems that can be used to store and extract electrical energy. A pumped thermal energy storage system of the present disclosure can store energy by operating as a heat pump or refrigerator, whereby net work input can be used to transfer heat from the cold side to the hot side. A working fluid of the system is capable of efficient heat exchange with heat storage fluids on a hot side of the system and on a cold side of the system. The system can extract energy by operating as a beat engine transferring heat from the hot side to the cold side, which can result in net work output.

Abstract: A method including: operating a pumped-heat energy storage (“PHES”) system in a generation mode to generate electricity; and responsive, at least in part, to a determination that a power generation plant will reduce supply of electricity to an electrical grid by a reduction amount of electricity, changing modes of the PHES system from the generation mode to operate in a charge mode. Operating in the charge mode can include receiving a charge amount of electricity, at least equal to the reduction amount of electricity, into the PHES system from the power generation plant and converting at least a portion of the charge amount of electricity to stored thermal energy.
