Moxion Power was a Richmond, California manufacturer of mobile battery energy storage systems: towable, zero-emission units sold as a replacement for diesel generators on construction sites, at live events, in film production and for disaster response. Its flagship MP-75/600 delivered 75 kilowatts of continuous power at 480 volts from a pack of more than 600 kilowatt-hours. Backed by Amazon's Climate Pledge Fund and Microsoft's Climate Innovation Fund, it shipped over 400 first-generation units before a failed fundraise forced it to close on 26 July 2024 and file for Chapter 7 liquidation.
