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.
