Joining forces to deliver clean energy to the grid

There's something poetic about the Mammoth Solar project in Kanawha County, West Virginia, being built on a reclaimed coal mine. True to its name, the massive project is designed to send clean energy to the grid to power Google's data centers in the area.

The utility-scale solar project will feature new, long-duration energy storage equipment that will help to better match intermittent renewable power generation with data center usage requirements.

The solar project, which will be owned and operated by MN8 Energy, is projected to launch commercial operations in 2028, with its storage solutions coming online in 2029 and 2030.

A vote of confidence for Eos Energy's tech

Google's stamp of approval is a big deal for Eos' Z3 zinc-based long-duration energy storage technology. One that could drive significantly more business to the high-performance battery maker.

Eos' system can provide 10 hours of storage, thereby enabling solar power to be delivered long after it's produced. In turn, Eos says the project will show that its aqueous zinc chemistry can become a valuable component of future grid infrastructure.

"Our work with Google is focused on deploying American-made long-duration storage where it solves real grid reliability challenges," Eos chief commercial officer Nathan Kroeker said. "Z3 extends the value of clean generation across more hours, strengthens the overall portfolio, and delivers more dependable capacity when it's needed most."
