Integration of Heat Pumps With Solar Thermal Systems for Energy Storage

Joshua McTigue, Pau Farres-Antunez, Christos Markides, Alexander White

Research output: Chapter in Book/Report/Conference proceedingChapter


This chapter considers the combination of solar thermal systems with an energy storage device known as a Carnot Battery which charges thermal storage with a heat pump or electric heater. Integrating these systems can provide a variety of advantages, such as dispatchable renewable power generation and electricity storage services. In this chapter a variety of methods for hybridizing these systems are described, and ideal cycle analysis is used to assess their relative merits.
