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.
