Fuel-cell startup Petra Power targets data centers and military vehicles

Petra Power sells solid oxide fuel cells that turn fuels such as natural gas into electricity without burning them, aiming to lower fuel costs and emissions for data centers and large vehicles. Founder Aaron Goodman said the cells are more compact and efficient than combustion-based generation because they remove electrons directly from fuel. The company is working with neoclouds and other infrastructure providers toward a first deployment in 2028 and full-scale production in 2029, while also targeting the Defense Department and eventually hyperscalers.

Petra Power, formed in 2017, develops ceramic solid oxide fuel cells that generate electricity from fuels such as natural gas without combustion. Founder Aaron Goodman says the approach cuts fuel costs and emissions while requiring less space and weight than conventional generation.

The company is pursuing data-center operators and the Defense Department. It is working with neoclouds and infrastructure providers toward a first deployment in 2028 and full production in 2029. Hyperscalers remain a goal without a firm agreement. Defense work is in testing for auxiliary vehicle power; Petra has about 15 staff and nearly $9 million in Defense Department contracts. It was also selected for TechCrunch’s Startup Battlefield 200.
