Zinc-based battery energy storage system provider Eos Energy Enterprises has secured a US$85 million loan facility with Atlas Credit Partners (ACP).

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.

When most people think of the metals that power today’s energy storage systems, vanadium and lithium are at front of mind. Ron MacDonald, president and CEO of Zinc8, argues the case for another metal playing an important role.
