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.
