Electricity Storage Technology Review
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.
Thermal energy storage capacity configuration and energy
Clearly, CO 2 thermal energy storage directly reduces the mass flow rate in the energy storage process, which also leads to a reduce in the system''s efficiency. As the second stage of thermal energy, CO 2 in the power plant has a lower temperature and energy grade compared to flue gas. The rated temperature at turbine inlet is 630 °C.

EPRI, Palo Alto, CA: 2019. 3002013868. Self-management found to increase costs when storage deployed. Greatest cost reduction and profits observed when ISO manages state of charge and optimizes to lower costs. Self-management still benefits efficiency if feasibility checked, allowing greater flexibility for participant.
