We're commercializing the most efficient and first truly fuel flexible power systems, starting with Diesel-APUs for long-haul and refrigerated trucking

We took our advanced Solid-Oxide technology and designed it specifically for the environmental and performance needs of long-haul trucks. Petra Power is building an APU for long-haul and reefer trucks that works with existing fuel supply chains while immediately improving fuel-efficiency, increasing power output, and reducing total cost of ownership. Our vision is to deploy environmentally impactful technology that trucking operators choose because our APU performs better at a lower cost.
Auxiliary Power Applications



The Benefits
leveraging power & versatility
Efficiency
Our solutions boast high efficiency levels, converting fuel into electricity with minimal wasted energy. This efficiency can lead to cost savings for businesses over time, especially in industries with high energy demands.
Reliability
We’ve made our proprietary systems known for durability and long lifespan compared to other types of fuel cells, making them a dependable choice for continuous power generation in an array of applications.
Sustainability
Petra-Powered systems offer significant environmental benefits, producing electricity through electrochemical reactions rather than combustion, immediately resulting in lower carbon emission levels
Versatility
Whether used for stationary power generation in buildings, distributed energy systems, or as a backup power source in remote locations, SOFCs can provide a flexible solution to meet diverse energy needs.
Size
Petra Power’s solid oxide fuel cells are razor-thin and highly efficient allowing them to pack a larger punch in a smaller package. The reduction in volume when transitioning from a combustion system to a Petra Power system is critical for industries such as defense and aerospace.
Weight
The weight of power systems is a limiting factor for the development of advanced technologies in shipping, aerospace, defense, and space applications. Petra Power’s fuel cell and electrolyzer systems are powered by lightweight ceramics that can help customers reduce their system weights and operate more efficiently.
