NASA’s Glenn Research Center developed a new flywheel-based mechanical battery system that redefined energy storage and spacecraft orientation. This innovative approach demonstrated the potential of ...

A flywheel is a very heavy wheel, formerly a large spoked wheel with a heavy metal rim but now more commonly made from a carbon-fiber composite material, with a smaller cylindrical form that is only ...

Energiestro co-founders Anne and André Gennesseaux (pictured) aimed to produce an affordable, scalable version of a flywheel energy storage system for use with renewable energy sources. The prototype ...

These systems offer high-efficiency, fast-response energy storage, and are gaining attention for grid stabilization, high-power applications, and renewable energy integration. The concept is not new.
