Abstract

A method for operating a pumped thermal energy storage (PTES) system involves circulating a working fluid through a working fluid circuit. The working fluid has a mass flow rate and a specific heat capacity, and the product of the mass and specific heat capacity of the working fluid is balanced on the high-pressure side and the low-pressure side of a heat exchanger as the working fluid flows through the working fluid circuit. The PTES system includes a bypass in the working fluid circuit whereby a first portion of the working fluid bypasses the high-pressure side of the heat exchanger while a second portion of the working fluid flows through the high-pressure side of the heat exchanger.
