Grid benefits, in particular, are amazing for a grid that needs to grow. Energy storage provides really fast frequency response (sub 4 seconds) that far exceeds the value and stability of conventional central plants. By the way, grid growth has many components -- electrification (heating, EVs, buildings), cryptocurrency, and AI.

Pumped hydro makes up 152 GW or 96% of worldwide energy storage capacity operating today. Of the remaining 4% of capacity, the largest technology shares are molten salt (33%) and lithium-ion batteries (25%). Flywheels and Compressed Air Energy Storage also make up a large part of the market.

In leading states like Texas and California, battery energy storage installations are driven by a desire to store excess power generated by abundant wind and solar PV resources.
