WebBy storing the hydrogen and oxygen in tanks, you can later create energy by burning it, or (more efficiently) by running it through a fuel cell (see How Fuel Cells Work). You can use the energy to spin up a flywheel and then later extract the energy by using the flywheel to run a generator. This patent has lots of information. WebApr 7, 2024 · A flywheel battery stores electric energy by converting it into kinetic energy using a motor to spin a rotor. The motor also works as a generator; the kinetic energy can be converted back to electric energy when needed. While the interest in flywheels soared in the late 1990s and 2000s, it had shortcomings.
WebSep 29, 2024 · Flywheel Energy Storage is a form of kinetic energy storage that uses rotating discs to store and release rotational energy. While the technology has been around for decades as a form of Uninterrupted Power Supply (UPS) to provide power when main sources fail, it has more recently begun to be refined and developed. WebSep 23, 2024 · A flywheel system stores energy mechanically in the form of kinetic energy by spinning a mass at high speed. Electrical inputs spin the flywheel rotor and keep it …
