The idea with a flywheel for power storage is that a small amount of electricity is used to keep a heavy mass rotating at a very high speed — 10,000 revolutions per minute (rpm) or faster. Then when power interruptions happen or some extra power is needed to stabilize the grid, that flywheel generates power, gradually slowing down in the process.

Thermal energy storage (TES) is the storage of for later reuse. Employing widely different technologies, it allows surplus thermal energy to be stored for hours, days, or months. Scale both of storage and use vary from small to large – from individual processes to district, town, or region. Usage examples are the balancing of energy demand between daytime and nighttim.

In the storing cycle, liquefied air is stored at low pressure in an insulated tank, which functions as the energy store. A cold box is used to cool compressed air using come-around air, and a cold storage tank can be filled with liquid-phase materials such as propane and methanol, as well as solid-phase materials such as pebbles and rocks.

Soda ash demand is dominated by glass with flat glass the single biggest end-use. In terms of demand growth, environmental sectors are contributing very positively with solar glass set to be the single biggest driver for soda ash demand by 2027. Lithium carbonate, a material used in some electric batteries, will also be an important demand driver.

When it is cheaper (usually at night), electricity is used to cool air from the atmosphere to -195 °C using the to the point where it liquefies. The liquid air, which takes up one-thousandth of the volume of the gas, can be kept for a long time in a large at . At times of , the liquid air is pumped at high pressure into a

General Atomics is developing a flow battery technology based on chemistry similar to that used in the traditional lead-acid battery found in nearly every car on the road today. Flow batteries store energy in chemicals that are held in tanks outside the battery. When the energy is needed, the chemicals are pumped through the battery.

In November 2019, Tesla used a Megapack to power a mobile recharging station for Tesla electric vehicles in California. The mobile Supercharger delivered 125 kW, and was transported on a flat trailer attached to a truck between deployment locations. In December 2019, Tesla delivered a 1.25 MW/2.5 MWh Megapack to the Substation in , Canada for . The battery is estimated to save owner Saint John Energ.

Energy storage can provide multiple benefits to the grid: it can move electricity from periods of low prices to high prices, it can help make the grid more stable (for instance help regulate the frequency of the grid), and help reduce investment into transmission infrastructure. Any must match electricity production to consumption, both of which vary significantly over time. Any combination of energy storage and demand response has these advantages:

As the world increasingly swaps fossil fuel power for emissions-free electrification, batteries are becoming a vital storage tool to facilitate the energy transition. Lithium-Ion batteries first appeared commercially in the early 1990s and are now the go-to choice to power everything from mobile phones to electric vehicles and drones.

Storage helps solar contribute to the electricity supply even when the sun isn’t shining. It can also help smooth out variations in how solar energy flows on the grid. These variations are attributable to changes in the amount of sunlight that shines onto photovoltaic (PV) panels or concentrating solar-thermal power (CSP) systems.

Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 to 13.
