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. These mechanical marvels convert electricity into rotational kinetic energy, spinning a mass at up to 50,000 RPM in near-frictionless environments. "A 10 kWh flywheel unit can deliver 500,000 full-depth cycles – about 10× more than top-tier lithium batteries."
[pdf] Israeli renewable energy company Nofar Energy Ltd will develop over 1 gigawatt-hour (GWh) of energy storage capacity across 60 locations in Israel. These locations belong to the retail chain Machsanei HaShuk. The estimated investment for the project is 500 million Israeli shekels (USD 135.1 million).
