Aaron Goodman doesn't oversell it. The Petra Power CEO, who studied plasma physics as part of his PhD work, knows that promising cleaner energy and cutting emissions by 90% is the easy part. Actually delivering at scale? That's where most fuel cell ventures have stumbled.
Still, the Ohio startup has assembled an intriguing hand: technology licensed from NASA Glenn Research Center back in 2017, $9 million in non-dilutive Department of Defense funding secured in 2023, and a market that suddenly seems willing to write billion-dollar checks for alternative power sources. Whether that's enough to break through in an industry littered with unfulfilled expectations remains an open question.
What's changed, perhaps more than the technology itself, is the urgency. Data centers can't expand fast enough to keep pace with AI workloads, and conventional grid connections aren't materializing quickly enough. Oracle didn't mess around—the company expanded its fuel cell procurement with Bloom Energy to 2.8 gigawatts in April 2026, a commitment that would have seemed fantastical a few years earlier. American Electric Power followed with its own deal for up to one gigawatt of solid oxide capacity late in 2025.
Those aren't pilot programs. They're infrastructure bets.
The Defense Angle
Petra's path has leaned heavily on government support, which in the fuel cell world is neither unusual nor disqualifying. The $9 million in non-dilutive DoD funding arrived in 2023, according to an Ohio Third Frontier Commission presentation dated April 2025. That same state document noted the company was raising a $1 million SAFE round at the time—modest by venture standards, but potentially sufficient for a team that's already working with government contracts.
The startup recently registered as a federal vendor, activating its UEI and CAGE codes as of January 8, 2026. That administrative milestone positions Petra to pursue additional defense contracts, which makes sense given the Pentagon's dual interest in operational resilience and decarbonization at remote installations.
Goodman, who studied plasma physics at Princeton before pivoting to fuel cells, presented at a NASA Startup webinar in late January 2025. The company has grown to somewhere between 11 and 50 employees, according to its LinkedIn profile, and relocated its headquarters to Solon, Ohio after incubating at BRITE Energy Innovators in Warren.
Small teams with government backing can move faster than people expect. Or they can get bogged down in bureaucracy. The trajectory of Petra, based on its government contracts and funding, remains a point of industry speculation.
What They're Claiming
The pitch revolves around solid oxide fuel cells that can run on eight different fuel types—hydrogen, natural gas, diesel, and others—while operating in reversible mode. That means the same unit can function as a fuel cell generating electricity (SOFC) or switch to electrolysis mode to produce hydrogen (SOEC). Flexibility like that appeals to operators juggling fluctuating energy prices and uncertain fuel availability.
Petra frames its technology as addressing what it calls the historic barriers to commercialization: cost, durability, impurity tolerance, and scalability. The 90% emissions reduction figure, prominently featured on the company's LinkedIn page, compares its systems to conventional combustion generators. Target applications include auxiliary power units, backup systems, data centers, and those defense installations.
The claims are compelling. They're also unverified by independent third parties, at least publicly. That's not unusual for early-stage companies, but it does mean buyers are taking performance on faith until proven otherwise.
A Crowded Field, Finally
Competition in the solid oxide space has thickened considerably. Bloom Energy dominates the commercial deployment landscape, with those massive Oracle and utility contracts as proof. Ceres Power, a UK firm with licensing partnerships across Asia, launched its "Ceres Endura" platform targeting cost reductions and longer operational lifetimes. Germany's Reverion raised funding in 2024 for containerized systems it claims can hit 80% electric efficiency. Serenity Power, a Canadian newcomer, announced pre-seed funding in late April 2026 for compact fuel cell systems aimed at similar markets.
Market forecasts from early 2024 are probably already stale given the pace of procurement announcements since then. What seems clear is that the conversation has shifted from megawatts to gigawatts—a jump that demands scalable manufacturing, not just clever engineering.
Whether Petra can translate NASA-licensed technology and DoD support into commercial traction at that scale is the real test ahead. The market appetite appears to be there, which is more than could be said five years ago.
Now comes the harder part: building the systems, hitting the specs, and convincing buyers to bet on the new entrant when established players are already signing contracts. Goodman and his team have the credentials and the backing. What they need next are reference customers and production volume.
That's where the story gets interesting.
