Known as the world’s ‘water batteries’, pumped storage hydropower is the cleanest and most cost-effective form of energy storage existing today. It makes up more than 95 per cent of global energy storage, next to less than five per cent combined for thermal, electromechanical and electrochemical storage, including lithium batteries.

One of the most promising materials is Graphene. It has a theoretical tensile strength of 130 GPa and a density of 2.267 g/cm3, which can give the specific energy of over 15 kWh/kg, better than gasoline (13 kWh/kg) and Li-air battery (11 kWh/kg), and significantly higher than regular Li-ion batteries.

Pumped storage hydropower is the world's largest battery technology, with a global installed capacity of nearly 200 GW – this accounts for over 94% of the world’s long duration energy storage capacity, well ahead of lithium-ion and other battery types. Water in a PSH system can be reused multiple times, making it a rechargeable water battery.

Pumped storage plants can operate with seawater, although there are additional challenges compared to using fresh water, such as saltwater corrosion and barnacle growth. Inaugurated in 1966, the 240 MW in France can partially work as a pumped-storage station. When high tides occur at off-peak hours, the turbines can be used to pump more seawater into the reservoir than the high tide would have naturally brought in. It is the only larg.

In 2009, world pumped storage generating capacity was 104 , while other sources claim 127 GW, which comprises the vast majority of all types of utility grade electric storage. The had 38.3 GW net capacity (36.8% of world capacity) out of a total of 140 GW of hydropower and representing 5% of total net electrical capacity in the EU. had 25.5 GW net capacity (24.5%.
