Petra Power Targets Data Centers and Defense With Solid Oxide Fuel Cells
Petra Power targets data centers and defense vehicles with solid oxide fuel cells, nearly $9 million in Defense Department contracts, and 2028 deployment plans.
Summary
Petra Power, founded in 2017 by Aaron Goodman, sells compact, lightweight solid oxide fuel cells for data centers and large vehicles. The ceramic devices convert fuels such as natural gas directly into electricity without combustion, bypassing the heat and motion stages that waste energy. Goodman says the approach can reduce fuel costs, emissions and physical footprint, although its efficiency advantage remains theoretical until demonstrated at scale.
The 15-person company is working with neoclouds and other infrastructure providers below hyperscaler scale, targeting its first customer deployment in 2028 and full-scale production in 2029. Petra considers hyperscalers its ideal customers because they consume the most power, but it has no firm agreements with them.
The Defense Department has awarded Petra nearly $9 million in contracts and is testing its cells as auxiliary power for onboard equipment when land vehicle engines are off. No live vehicle has deployed the technology, and the government has not decided whether to proceed. Petra hopes to expand the defense work and was selected among 200 companies for Startup Battlefield 200, held October 13 to 15 at Moscone West in San Francisco.
Positives
- Nearly $9 million in Defense Department contracts gives Petra funding and a government testing pathway.
- A 2028 first deployment target gives neoclouds and infrastructure providers a defined commercialization milestone.
- Solid oxide fuel cells could reduce fuel costs, emissions, weight and footprint by converting fuel directly into electricity.
- Full-scale production is targeted for 2029 if customer deployments and testing progress.
- Startup Battlefield 200 selected Petra among 200 participating startups.
Risks & concerns
- No firm hyperscaler agreement exists despite those companies being Petra’s ideal and highest-impact customers.
- No live defense vehicle has deployed Petra’s fuel cells, which remain in government testing.
- The Defense Department has not decided whether to move beyond the current evaluation phase.
- A 15-person team must advance customer deployments by 2028 and reach full-scale production one year later.
- Claims of lower costs, emissions and energy losses have not yet been demonstrated at commercial scale.
