Petra Power bets on fuel cells for AI data centers
Original: Petra Power looks to modernize energy for data centers and defense vehicles
Why This Matters
Solid oxide fuel cells could offer data centers a lower-emission, off-grid power path as AI workloads surge.
Petra Power, founded in 2017, sells solid oxide fuel cells that convert natural gas to electricity without combustion. It targets data centers and U.S. defense vehicles, with first deployments planned for 2028 and full production in 2029.
As AI drives electricity demand higher, Petra Power is pitching solid oxide fuel cells as a cleaner, cheaper alternative to conventional power generation. Founded in 2017 by Aaron Goodman, the company makes ceramic devices that strip electrons directly from fuel — skipping the combustion-to-heat-to-motion chain that Goodman argues loses energy at every step. "It's one step, no loss," he told TechCrunch, adding that the result is substantially lower fuel costs and a smaller physical footprint than diesel generators or grid-tied systems.
Petra is chasing two customer segments. On the commercial side, it's in talks with neoclouds and infrastructure providers a tier below the major hyperscalers, targeting first deployment in 2028. Hyperscalers remain the long-term goal — "they're the largest consumers of power," Goodman said — but no firm agreements exist there yet. On the defense side, the company wants its cells to supply auxiliary power for land vehicles, running onboard electronics when the main engine is off. Full-scale production is targeted for 2029. No specific customer agreements have been disclosed.
