Moreover, flow batteries can be cycled indefinitely, meaning they are less prone to capacity fade compared to their lithium-ion counterparts.

2.2 PUMPED HYDRO STORAGE

Pumped hydro storage constitutes another essential technology within the energy storage landscape. This method involves transferring water between two reservoirs situated at different elevations. During periods of excess energy generation, water is pumped from the lower reservoir to the upper reservoir, thus storing gravitational potential energy. When energy demand rises, this stored energy is released by allowing water to flow back down, driving turbines to generate electricity.

This technology has been widely utilized across various regions, providing substantial capacity for bulk energy storage. Furthermore, pumped hydro offers significant advantages, such as a long operational lifespan and relatively low maintenance costs. However, the ecological impact and geographical constraints can pose substantial implementation challenges. Environmental considerations must be at the forefront of planning these facilities to ensure sustainability and minimal disruption to surrounding ecosystems.
