Form Energy will receive $147 million to build a facility in Maine capable of storing enough energy to provide 85 megawatts of power for up to 100 hours.

    very cool, iron-air not lithium ion. good to see less energy dense batteries getting used for grid storage.

    next I’d like to see up-cycled car batteries converted to grid storage.

    From what I can gather, the proposed battery will have a capacity of 8.5GWh with a nominal output of 85MW. But it can store 85MW (not MWh) for 100 hours? Either that article is written by someone who doesn’t really know what they’re relaying, or that’s some serious standby power dissipation.

    Anybody here who passed high school physics and have some insights?

      It can store enough energy to output 85MW for 100 hours, which is 8.5GWh. That’s also probably very optimistic math, unless it actually stores more than 8.5GWh, and that’s the reduced value accounting for losses
