Iron electrolyte flow battery company ESS Inc has become the latest energy storage industry player to target public listing of its stock, announcing a merger with a special purpose acquisition company (SPAC).
Eos Energy Enterprises, the NASDAQ-listed designer and manufacturer of energy storage systems based on the company’s aqueous zinc battery technology, has announced three large-scale projects in the US and India.
A zinc-air energy storage system (ZESS) offering 10 hours of storage is being trialled in a New York Power Authority (NYPA) project, while a US Department of Defense-funded investigation into flow batteries has moved into a physical validation and evaluation phase in Colorado.
While lithium-ion continues to dominate big project announcements worldwide, three providers of long-duration non-lithium battery technologies have claimed various milestones in commercialisation.
