The storing of electricity typically occurs in chemical (e.g., lead acid batteries or lithium-ion batteries, to name just two of the best known) or mechanical means (e.g., pumped hydro storage). Thermal energy storage systems can be as simple as hot-water tanks, but more advanced technologies can store energy more densely (e.g., molten salts
Pumped storage hydropower is the world''s largest battery technology, accounting for over 94 per cent of installed global energy storage capacity, well ahead of lithium-ion and other battery types.

Pumped hydro The total energy storage capacity of the U.S. grid is less than 1 percent, according to Barnhart. What little capacity there is comes from pumped hydroelectric storage, a clean
While battery storage is more flexible, pumped hydro energy storage is more cost-effective and has a longer lifespan. The decision of which technology to use depends on specific needs and geographic location. In the end, they both have a role to play in the transition to renewable energy and a sustainable future.
Energy storage systems (ESS) will become India''s most invested-in clean energy asset class during this decade, but it''s likely to be pumped hydro, not lithium-ion batteries, that see the most deployments.
