Voya Energy raised $35 million in a Series A financing round led by Energy Impact Partners, with participation from John Doerr, Mantis VC, StepStone, Founders Fund, Overmatch, Seven Stars and other institutional investors.
The Hayward, California-based company introduced an aluminum-based fuel system integrated with an electrochemical generator designed to produce electricity without combustion or air emissions at the point of use. The technology converts low-grade scrap aluminum into electricity through a low-temperature electrochemical process.
At an industrial scale, the system is engineered to generate up to two megawatts from a standard 20-foot container. Voya Energy projects that, at full deployment, each acre of installation could support approximately 100 megawatts of generation capacity and 10 gigawatt-hours of stored energy. The company claims this configuration requires roughly four times less space than diesel generator fleets and 100 times less than grid-scale battery installations.
The system operates independently of the utility grid, targeting large energy users such as data centers, industrial operators and other facilities constrained by grid access, permitting or fuel logistics. Nearly a dozen companies across data centers, industry, transportation, utilities and infrastructure have partnered with Voya Energy to conduct pilot demonstrations in the near term.
Capital from the financing will fund technology development, initial deployments planned for 2027 and manufacturing scale-up targeted for 2028.
