How It Works
Storing electrical energy as a differential of temperature.
Zero Charge
System at a fully discharged state where LTR has chilled water and HTR has warm oil/concrete media.
Charging
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.
Fully Charged
System at a fully charged state where water has frozen in the LTR and oil/concrete media is hot in the HTR.
Discharging
sCO2 equipment is operated as a heat engine: temperature differences between the energy storage reservoirs drive expansion across a turbine-generator, producing electricity.
