The rise of water batteries: a new era of hydroelectric energy storage
Water batteries like Nant de Drance and ''Hollow Mountain'' hold great potential for energy storage and grid resilience. They can store excess energy when it is not needed and release it to generate electricity when demand is high.
Pumped storage-based standalone photovoltaic power generation system
As illustrated, when solar power generation is higher than energy demand, the surplus of energy is used to pump water from a low reservoir to a high reservoir, storing energy in the form of gravitational potential energy of the water (charging/pumping mode, Fig. 1 a). When power needs to be dispatched, water is allowed to flow back downhill
