Heat transfer fluid and material selection for an innovative Pumped Thermal Electricity Storage systemENERGY -OXFORD-BenatoAlbertoStoppatoAnna
Here we formulate a simple thermodynamic model that predicts the efficiency of PHES as a function of the temperature of the thermal energy storage at maximum output power. The resulting equation is free of adjustable parameters and nearly as simple as the well-known Carnot formula. Our theory ...
