FREQUENTLY ASKED QUESTIONS

WHAT IS PUMPED HYDRO STORAGE?
Pumped hydro storage is an energy storage method that utilizes gravity to generate electricity. In its operation, water is pumped from a lower reservoir to an upper reservoir during periods of low electricity demand, primarily when energy costs are cheaper. Conversely, during high-demand periods, the stored water is released back to the lower reservoir through turbines, generating electricity in the process. This system can provide significant energy storage capacity and is particularly effective in areas with geographical features supportive of such installations. The technology not only allows for energy balancing but also aids in maximizing the use of renewable energy sources, supporting grid stability, and providing an efficient means of responding to sporadic energy usage patterns.

HOW DOES THERMAL ENERGY STORAGE WORK?
Thermal energy storage systems capture excess heat produced from renewable energy sources and store this energy for later use. These systems typically employ materials that can absorb and retain heat for extended periods. One commonly used method involves molten salts that are heated and stored until energy is needed. When the demand arises, the stored thermal energy is converted to electricity by generating steam to drive turbines. The technology is particularly beneficial for solar energy applications, as it helps to mitigate the inherent intermittency of solar power generation. By enabling the continued supply of energy even after daylight hours, thermal storage enhances the overall effectiveness of solar energy systems, contributing to a more reliable power supply and facilitating the transition to sustainable energy solutions.
