Storing electrical energy as a differential of temperature.
System at a fully discharged state where LTR has chilled water and HTR has warm oil/concrete media.
sCO2 equipment is operated as a heat pump: electricity is consumed as high temperature heat of compression is extracted and stored in HTR oil media while low temperature turbine expansion converts water to ice in LTR.
System at a fully charged state where water has frozen in the LTR and oil/concrete media is hot in the HTR.
sCO2 equipment is operated as a heat engine: temperature differences between the energy storage reservoirs drive expansion across a turbine-generator, producing electricity.
Lower Capex, no augmentation costs => Lower LCOS
One of the most compact LDES footprints at ~5 acres for +GWh
From 8 hours to multiple days of stored capacity & other ancillary services
Maximize capacity factor by enhancing load following with reactor at ~100% MWt
