Levistor develops inherently safe flywheel technology to reduce the costs of high-power, short-duration energy storage. Our inherently safe flywheels require little containment and no safety enclosures or bunkering that flywheels traditionally require to protect people and property in the event of a mechanical fault. This brings down the cost and makes flywheels a viable technology for supply bursts of energy, as in EV charging or regenerative braking. Our patented laminated flywheel uses sheets of high-strength, low-cost steel to allow higher speeds, lower costs and a structure than ensures a crack can never pass from one sheet to the next. We can thus achieve a high energy density, lower cost and safer flywheel than competitors.
