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 flywh. Flywheel systems excel in frequency regulation, capable of second-to-second adjustments to stabilize the grid. As frequency fluctuates, flywheels can either absorb energy, thus reducing overall generation levels, or release energy during instances of excess demand. [pdf]
