Voya Energy closed a $35 million Series A financing round to advance its aluminum based metal fuel energy system toward commercial deployment.
Voya Energy secured $35 million in Series A funding, led by Energy Impact Partners, to commercialize its scrap-aluminum electrochemical generators for clean, grid independent power at data centers and industrial sites starting with 2027 deployments.
What is Voya Energy?
The Hayward, California-based company, founded in 2025, develops an integrated platform that pairs proprietary aluminum based fuel (produced from low grade scrap aluminum and formed into pellets) with purpose built electrochemical generators. These convert the fuel directly into electricity via a low temperature electrochemical process involving reaction with air and water, enabled by a proprietary electrolyte and metal-air cell technology. The system produces no combustion, no air emissions (zero criteria pollutants or carbon emissions) at the point of use, operates independently of the utility grid, and yields a recoverable aluminum trihydrate (ATH) byproduct that can be sold as an industrial feedstock (e.g., for water treatment, flame retardants) or eventually recycled in a closed loop system.
The Series A was led by Energy Impact Partners (EIP), with participation from John Doerr (Founder at Doerr Capital and Chair at Kleiner Perkins), Mantis VC, StepStone, Founders Fund, Overmatch, Seven Stars, and other institutional investors. This follows a $13 million seed round (announced around November 2025, with some references to July 2025), also led by EIP, bringing total capital raised to approximately $48 million.
Proceeds will fund continued technology development, initial product deployments and site testing targeted for 2027, and manufacturing scale-up in 2028. The platform is expected to qualify for the federal clean electricity investment tax credit under Section 48E for eligible fuel cell systems.
Technology and System Performance
Voya’s modular design centers on 50 kW power modules. Configurations include:
- Commercial generators (up to five modules, ~250 kW) in compact form factors.
- Industrial generators (40 modules, up to 2 MW) housed in a standard 20 foot container.
These pair with separate 10 foot fuel containers (~100–104 MWh of stored energy from aluminum pellets) and byproduct containers for ATH. At scale, the system targets approximately 100 MW of generation capacity and 10 GWh of stored energy per acre, described as about four times more compact than diesel generator fleets and 100 times more compact than grid scale battery installations. Fuel is stable for long term (potentially decades) storage and transport via standard logistics, non flammable, and energy-dense. Conversion efficiency is indicated at around 57%, compared with ~35% for conventional diesel generators. Generators are designed for ultra silent operation (~60 dBA at 3 m), instant dispatchability, battery like power quality, and exemption from typical air quality permits or runtime restrictions.
Core technologies include pelletized metal fuel optimized for handling and density; unique metal-air cell design; advanced proprietary electrolyte; and ATH recovery/recycling processes.
Primary near term focus is data centers and other large energy users facing grid constraints, delayed interconnections, limited local capacity, permitting hurdles, or community concerns over noise and emissions from conventional backup generation (such as diesel). The system aims to provide firm, on-site power for backup, bridge capacity during grid delays, peak support, demand response, and flexible generation, potentially reducing reliance on fossil fueled options while enabling faster deployment without fuel pipelines.
Additional applications include commercial and industrial facilities, energy infrastructure (distributed generation where transmission or capacity is constrained), off-grid or remote sites, and longer term opportunities in heavy transport (e.g., marine and rail) where high energy density and logistics compatibility matter. Nearly a dozen partners across industrial manufacturing, data centers, utilities, real estate, emergency response, energy infrastructure, and related sectors are engaged for pilot demonstrations to refine the technology for commercial use.

Community and permitting advantages are highlighted: zero local emissions and quiet operation address backlash against data center projects (with reports of significant delays or cancellations tied in part to conventional generation impacts). The system can also serve as distributed grid resources for peak reduction or emergency capacity.
Who are Voya Energy’s leaders?
Co-founders are Richard Wang (CEO; previously founded Cuberg, an advanced battery company acquired by Northvolt, and later served in leadership there), Matt Horton (Chief Commercial Officer; prior CEO roles at Voltera and others, plus leadership in EV charging and energy at Rivian and Proterra), and Steven Kaye (CTO; extensive experience in energy storage materials, with prior CTO/VP roles and more than 60 patents). Shayle Kann of Energy Impact Partners played a key role in conceiving and building the company alongside the founders. The firm has roughly 36–39 employees.
The funding and product unveiling position Voya to commercialize a novel energy storage and generation category based on abundant, recyclable metals. Aluminum’s established global supply chains (including scrap streams), high energy density, safety profile, and compatibility with existing logistics differentiate it from liquid fuels or batteries for long duration, transportable, firm power. Near term milestones center on 2027 pilots and deployments, with manufacturing ramp in 2028. Longer term vision includes establishing metal fuels as a scalable alternative for on-site critical power and broader energy delivery unconstrained by traditional grid or fossil infrastructure limitations.
Investor backing from climate/tech focused firms and prominent individuals underscores confidence in the technology’s potential to address rising electricity demand, particularly for data centers and industrial growth constrained by grid timelines and environmental permitting.
