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.
Peak-shaving with photovoltaic systems and NaS battery storage. From the utility''s point of view, the use of photovoltaic generation with energy storage systems adds value by allowing energy utilization during peak hours and by modeling the load curve. An example of this application can be seen in Fig. 9.
