Google backed a West Virginia solar-storage project planned with 100 megawatt-hours of Eos zinc-based storage alongside lithium-ion batteries.

Utility Dive reports that Google is backing a solar-and-storage project at a former West Virginia coal mine. MN8 is developing the project, separating the developer’s role from Google’s reported backing.

The planned storage configuration includes 100 megawatt-hours of long-duration, zinc-based storage from Eos Energy Enterprises, alongside lithium-ion batteries. The 100-megawatt-hour figure applies to the Eos storage component, not necessarily to the combined storage installation.

Megawatt-hours measure stored energy, not the solar plant’s generating capacity or the batteries’ discharge-power rating. The supplied excerpt does not provide those power ratings, the lithium-ion storage capacity, an operating date, or the financial and contractual form of Google’s support.
