Petra Power Targets Data Centers and Military Vehicles With Solid Oxide Fuel Cells

As expanding artificial intelligence workloads drive up electricity consumption across computing infrastructure, energy startup Petra Power is pitching solid oxide fuel cells as a compact, low-emission power source for data centers and military equipment. Founded in 2017 by Aaron Goodman, the company designs ceramic devices that convert fuels such as natural gas directly into electricity without combustion.

According to an interview Goodman gave to TechCrunch Startups (https://techcrunch.com/2026/10/10/petra-power-looks-to-modernize-energy-for-data-centers-and-defense-vehicles/), the company's fuel cells yield lower fuel costs and emissions compared to conventional thermal generation while occupying a smaller physical footprint. Traditional power plants rely on multiple mechanical steps—burning fuel to create heat, converting heat to motion, and using motion to drive a generator—each introducing energetic losses. Petra Power's ceramic cells instead strip electrons directly from the fuel in a single electrochemical reaction.

Petra Power is focusing on two primary customer segments: commercial data center operators and the U.S. Department of Defense. On the commercial side, Goodman said the company is currently working with neoclouds and mid-tier digital infrastructure providers, targeting initial commercial deployments in 2028 and full-scale manufacturing by 2029. While hyperscale cloud providers represent the company's ideal customer profile given their power demands, Goodman noted that discussions remain exploratory without firm agreements.

For defense applications, the startup is developing auxiliary power systems designed to operate electronics and onboard equipment in land vehicles when the primary combustion engine is switched off. The hardware is not yet in operational field service; it remains in government testing as military evaluators decide whether to advance the program.

Operating with a team of roughly 15 employees, Petra Power has received nearly $9 million in Department of Defense contracts to date. The startup was also selected for the TechCrunch Startup Battlefield 200 cohort ahead of its planned manufacturing expansion.
