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 flywheel systems would eliminate many of th.

Some forecasts predict a 40-50% reduction in average solar costs by 2030. After a period of inflation-driven price hikes, module prices have recently fallen to historic lows due to the polysilicon supply glut and expanded manufacturing capacity.

Vanadium redox flow batteries are the most commercially mature LDES technology available in 2026. VRFBs store energy in liquid electrolytes containing vanadium ions in different oxidation states — V²⁺/V³⁺ at the anode, V⁴⁺/V⁵⁺ at the cathode — separated by an ion-exchange membrane.
