What is the nature of the "Pumped thermal grid storage with heat exchange?"

  • Quantum Mechanics

  • Gravity

  • Thermodynamics

  • Particle Physics

Answer

The nature of pumped thermal grid storage involves storing thermal energy by exploiting temperature differences between two water reservoirs at different elevations. When there is excess electricity, water is pumped from the lower reservoir to the upper one, storing energy in the form of potential energy.
