Parametric studies and optimisation of pumped thermal electricity storage

McTigue, Joshua D.; White, Alexander J.; Markides, … - In: Applied Energy 137 (2015) C, pp. 800-811

Several of the emerging technologies for electricity storage are based on some form of thermal energy storage (TES). Examples include liquid air energy storage, pumped heat energy storage and, at least in part, advanced adiabatic compressed air energy storage. Compared to other large-scale...
