This post looks at fifteen kinds of utility or grid scale energy storage solutions that are either in wide use or have significant potential to supply the energy storage capacity that will help make the grid both more efficient and more robust. These range from pumped hydro, which is by far the most prevalent form of energy storage at this scale to compressed air, thermal storage, advanced batteries, fuel cells and purely electric storage systems.
The U.S. Department of Energy (DOE) has announced $104.7 million in funding for seven new research and testing facilities located in DOE national laboratories. The announced projects will support the development and improvement of clean energy and efficiency technologies that are in the US strategic national interest. The new funding is supporting research in techniques to reduce the cost to manufacture carbon fiber on a large scale; finding ways to improve efficiency and lower costs for car batteries; and for developing net-zero energy building technologies.
