Abstract
Energy storage and retrieval systems are disclosed, along with methods of storing and retrieving the energy. One system includes a thermal energy storage subsystem and a trilateral cycle, with first and second heat exchangers. The first heat exchanger exchanges heat between the energy storage medium and the working fluid, and the second heat exchanger exchanges heat between the high- and low-pressure sides of the trilateral cycle. Another system includes a conduit fluidly connecting pressurized gas in low- and high-temperature thermal energy storage tanks and passing through a heat exchanger in which the gas in the conduit exchanges heat with the thermal energy storage medium and/or the working fluid, enabling recovery of heat lost to evaporation of the thermal energy storage medium during discharge of the stored thermal energy in the system. The methods relate to various operations of the systems.
