The same solid oxide cells that made oxygen on Mars are now being scaled to produce green hydrogen on Earth.

Summary
North Salt Lake-based OxEon Energy makes solid-oxide electrolysis systems for hydrogen, synthetic fuels, energy storage, and oxygen production. Its hardware links Utah to industrial decarbonization and Mars resource systems; if deployed at scale, that capability changes more than a single product market.
Impact
The impact case rests on solid oxide electrolyzer cells being among the most thermodynamically efficient pathways to green hydrogen. SOEC systems operating at 700–900°C can achieve system efficiencies of 80–90%, outperforming low-temperature alternatives (PEM, alkaline) when paired with industrial waste heat. If green hydrogen reaches cost parity with fossil-derived hydrogen — a goal multiple national energy policies are funding — SOEC technology is likely to be part of that stack.
OxEon's Mars heritage is not merely a branding asset: extreme-environment validation in a closed-loop, no-maintenance context provides reliability data that Earth-side competitors lack. The DOE $36M hydrogen manufacturing grant (2024) signals that federal funders believe OxEon can scale beyond laboratory MOXIE-sized cells to industrial production volumes.
What They Are Building
OxEon builds SOEC stacks and complete systems for hydrogen production, carbon monoxide production, and co-electrolysis (simultaneous hydrogen and CO, enabling synthetic fuel pathways). Their cells use ceramic materials that operate at high temperature and pressure. The Mars application required cells that could start from a cold state, operate autonomously, and survive dust, radiation, and thermal cycling — constraints that drove robustness into the core design.
Current scale-up work is focused on high-volume manufacturing: reducing per-cell cost and improving durability over thousands of operational hours, which is the primary commercial challenge for all solid oxide systems.
What They Need Now
Hiring frames around manufacturing scale-up — engineering, manufacturing, operations, and business development as capacity ramps. That aligns with the longer-standing need for electrochemists, ceramics and materials scientists, thermal systems engineers, and manufacturing process engineers who can take small-batch SOEC production to factory scale; industrial-hydrogen chemical engineers remain relevant given DOE manufacturing grants.
Who Could Help
Useful helpers include DOE national laboratory partners (Idaho National Lab, National Renewable Energy Lab), hydrogen offtake partners in industrial chemicals or refining, aerospace customers evaluating in-situ resource utilization (ISRU) for lunar or Mars applications, and investors with deep-tech energy patience (SOEC commercialization is a multi-year capital cycle).
Utah Context
North Salt Lake is not a traditional clean-energy hub, but OxEon's presence reflects the University of Utah's strength in materials science and electrochemistry. The company's DOE funding profile is consistent with other Utah deep-tech firms that grow on federal grants rather than venture capital, giving founders more autonomy and longer time horizons at the cost of slower scale.
