Advances in solid-state, sodium-ion, and flow batteries promise higher energy densities, faster charging, and longer lifespans, enabling electric vehicles to travel farther, microgrids to operate efficiently, and renewable energy to integrate seamlessly into the grid. . The Breaking It Down series aims to inform and inspire people by putting advanced manufacturing technologies and processes into simpler terms. With electric vehicles (EVs) that get us places, cell phones that connect us to others, and utility-scale electric grid storage that powers our homes. . Energy storage beyond lithium ion is rapidly transforming how we store and deliver power in the modern world. Battery storage is the fastest responding dispatchable. .

Currently, the most widely deployed large-scale mechanical energy storage technology is pumped hydro-storage (PHS). . Mechanical energy storage can be added to many types of systems that use heat, water or air with compressors, turbines, and other machinery, providing an alternative to battery storage, and enabling clean power to be stored for days. The energy industry as well as the U. Department of Energy are investing in mechanical energy storage. . Hence, mechanical energy storage systems can be deployed as a solution to this problem by ensuring that electrical energy is stored during times of high generation and supplied in time of high demand. While the physics of mechanical systems are often quite simple (e. These devices include technologies like pumped hydroelectric. .
