Thermodynamic analysis of pumped thermal electricity storage

The thermal stores are arranged vertically, as shown, so as to prevent buoyancy-driven instabilities of the thermal fronts. The energy is stored as ''sensible heat'', enabling efficient integration with the thermodynamic cycle and avoiding the ''pinch-point'' difficulties associated with phase-change storage methods.

Thermal energy storage

Thermal energy storage ( TES) is the storage of thermal energy for later reuse. Employing widely different technologies, it allows surplus thermal energy to be stored for hours, days, or months. Scale both of storage and use vary from small to large – from individual processes to district, town, or region.
