Development of a High Specific Energy Flywheel Module,

a rapidly spinning wheel - with 50 times the Storage capacity of a lead-acid battery As the flywheel is discharged and spun down, the stored rotational energy is transferred back into electrical

Flywheel Energy Storage System: What Is It and How Does It

In essence, a flywheel stores and releases energy just like a figure skater harnessing and controlling their spinning momentum, offering fast, efficient, and long-lasting energy storage.

In the 1950s, flywheel-powered buses, known as gyrobuses, were used in Yverdon (Switzerland) and Ghent (Belgium) 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
