Energy Storage
Technology that stores electrical energy through means such as lithium batteries and flow batteries and releases it when needed. It can provide second-level backup power for data centers and participate in ancillary services such as grid frequency regulation and peak shaving.

Directions for easing the conflict between data center expansion and emissions reduction include: improving chip energy efficiency, optimizing cooling technology, siting in clean-energy-rich regions, and investing in low-carbon power sources such as energy storage and nuclear power.
The 24/7 carbon-free energy goal requires that electricity use be matched hour by hour with local carbon-free power sources, placing higher demands on grid structure and energy storage, and is difficult to fully implement in the short term.
Energy storage installations are growing quickly, but the adaptation speed of interconnection approvals, transmission capacity, and dispatch mechanisms may not keep pace, which will delay the conversion of installed capacity into actual regulation capability.
The grid connection of gigawatt-scale data center clusters requires supporting energy storage, reactive power compensation, and dynamic voltage restorers to smooth voltage fluctuations and frequency disturbances.
Texas is one of the fastest-growing energy storage markets in the United States.
Texas storage duration is generally on the order of 2-4 hours, which is still difficult to fully cover Dunkelflaute caused by multiple consecutive days of low wind speeds or overcast skies.
At a stage when large-scale energy storage deployment is not yet in place, natural gas generation, with its flexible start-stop capability and relatively low unit cost, has become the most realistic option for filling the baseload and peak-shaving gap.
Estimating a large data center at a continuous power consumption of 100 MW, if it needs to run on energy storage alone for 10 hours without sunlight, it would require about 1 GWh of energy storage capacity.
Energy storage is eroding the market share of gas peaking rather than fully replacing dispatchable power sources in the short term, and the two will have a complementary relationship in the future.
Energy storage can simultaneously participate in multiple markets including energy arbitrage, frequency regulation, and reserve capacity, with stacked revenues amortizing costs.
