Aluminum fuel converts scrap metal into 2 MW of clean, firm power on demand

Voya Energy's aluminum-fueled system is designed to generate up to 2 MW of power in a 20-foot container.Voya Energy Hayward, California-based firm Voya Energy has unveiled an aluminum-based power system that can generate electricity without combustion, while aiming to provide large energy users with power independent of the utility grid. The company combines a proprietary aluminum fuel with a purpose-built electrochemical generator. Instead of burning fuel to produce electricity, the system uses a low-temperature electrochemical process to convert aluminum into power. Voya says its fuel can be made from low-grade scrap aluminum, giving the system a potential route to turn an abundant waste material into a source of firm electricity. The company is targeting data centers, industrial facilities and other large power users facing grid-access, permitting or fuel-logistics constraints. The company also announced a $35 million Series A funding round led by Energy Impact Partners. The financing includes participation from John Doerr, Mantis VC, StepStone, Founders Fund, Overmatch, Seven Stars and other institutional investors. Aluminum turns waste into power At industrial scale, Voya’s system is designed to produce up to 2 megawatts from a standard 20-foot container. The company says its technology could eventually deliver about 100 megawatts of generation capacity and 10 gigawatt-hours of stored energy per acre. That footprint could make the technology particularly relevant where space is limited. Voya estimates that its system could be about four times more compact than diesel generator fleets and 100 times more compact than grid-scale battery installations. The company says its approach can provide “clean, firm” electricity without combustion or air emissions at the point of use. That could give operators an alternative to conventional diesel generators for backup and off-grid power, while avoiding direct combustion emissions. “America needs dramatically more electricity to power our industries, strengthen our communities, and support continued economic growth,” said John Doerr, Founder at Doerr Capital and Chair at Kleiner Perkins. “Meeting that demand requires new technologies that can deliver clean, firm power at speed and scale. Voya is taking a bold approach to that challenge, turning abundant aluminum into a practical source of 24/7 power wherever it is needed.” Two megawatts inside one container The system’s proposed scale is aimed at a growing problem for electricity-intensive facilities: getting enough power from the grid quickly. Rather than waiting for new grid connections or relying entirely on conventional generators, Voya wants its technology to provide power directly at the site. The company says nearly a dozen companies spanning data centers, industry, transportation, utilities and infrastructure are already working with it on pilot demonstrations. The initial deployments are planned for 2027, giving Voya an opportunity to test the system with commercial users before moving toward larger-scale manufacturing. The company plans to use the new financing for technology development, those early deployments, and manufacturing scale-up targeted for 2028. The aluminum fuel approach also gives the system an energy-storage component. Rather than generating electricity only when fuel is consumed, the material can serve as a stored energy source that is converted to electricity through the electrochemical generator when power is needed. Voya plans to use the new funding for further technology development and initial deployments in 2027, followed by manufacturing scale-up in 2028.Get the latest in engineering, tech, space & science - delivered daily to your inbox.With over a decade-long career in journalism, Neetika Walter has worked with The Economic Times, ANI, and Hindustan Times, covering politics, business, technology, and the clean energy sector.
