What this means for investors The collaboration among the three companies will be owned and operated by power platform MN8 Energy, which will use Eos Energy's zinc-based and lithium-ion storage energy solutions to power Google's data centers. In a press release, MN8 went on to explain: The integrated portfolio adds new clean, dispatchable capacity to the grid serving Google's data centers in the region, including a planned project in West Virginia. The solar project is expected to reach commercial operation in 2028, with lithium-ion storage and long-duration storage following in 2029 and 2030, respectively.

In less than a year, EOSE stock has plummeted from $18 to $3. 61 amid earnings misses, a lack of progress toward profitability, and manufacturing delays, but today's news may offer a lifeline for the once-promising energy storage company. That said, Eos has burned $422 million in FCF while earning $214 million in sales over the last year, so it is far from out of the woods, even with this deal.

Investors should be prepared for volatility if they are interested in the stock, as equity and debt raises will be likely. Should you buy stock in Eos Energy Enterprises right now?
