2. HOW DOES PUMPED HYDRO STORAGE WORK IN PRACTICE?

Pumped hydro storage operates through a dynamic process involving two water reservoirs positioned at different elevations. During periods of low energy demand or when renewable energy generation exceeds consumption, electricity is utilized to pump water from the lower reservoir to the upper one. This conversion of electrical energy into gravitational potential energy allows for energy to be stored effectively.

When demand on the energy grid increases, the stored water is released from the upper reservoir back down to the lower one. As it descends, the potential energy is converted back into kinetic energy, driving turbines that generate electricity. The efficiency of this system is particularly noteworthy, with many pumped hydro facilities exhibiting round-trip efficiencies of over 70%.

This form of energy storage plays a critical role in stabilizing the electricity supply for Hainan as it transitions to renewable energy sources. By storing excess energy during sunny or windy periods, pumped hydro systems facilitate a sustainable approach to energy management. They enable electric grids to balance fluctuating supply with variable demand levels throughout the day.
