High initial costs, specific applications, limited energy density, short discharge duration: Flywheel energy storage systems are characterized by their innovative design for energy storage and release; however, they also come with significant drawbacks.
Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in , and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. The first pumped hydroelectricity was constructed at the end of the 19th century around in Italy, Austria, and Switzerland. The technique rapidly expanded during the 196. Energy storage can save operational costs in powering the grid, as well as save money for electricity consumers who install energy storage in their homes and businesses.

A 2023 study revealed that projects requiring **10+ hours of storage duration** achieve up to 40% lower levelized cost of storage (LCOS) with VRFBs compared to lithium-ion alternatives, making them economically viable for grid stabilization in regions with high renewable penetration.

In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity. It is hoped that flywheel systems can replace conventional chemical batteries for mobile applications, such as for electric vehicles. Proposed flywhe.
Cornex New Energy Co.,Ltd. is a globally-oriented new energy innovation and technology company of lithium-ion battery, which focuses on the development, manufacturing and sales of traction battery and energy management system which includes electrochemical energy storage, electric vehicle, commercial vehicle, construction machinery and others.
Energy storage could save taxpayers in Germany some €3 billion (US$3.3 billion) in subsidies for renewable energy assets by 2037, simply by increasing demand in the wholesale electricity market.
