From lab research to real energy systems.
Engineers and scientists and operators; the team behind iron-based thermochemical storage, developed at McGill and built for industrial deployment.
From a McGill laboratory to commercial energy systems.
FeX Energy’s technology was developed at McGill University’s Alternative Fuels Laboratory, where Professor Jeffrey Bergthorson spent over fifteen years researching iron-based thermochemical energy storage.
FeX was founded to bring that research out of the laboratory and into real industrial energy systems.

Impact
Our business is a gateway to a sustainable planet for future generations. We build technology that reduces industrial emissions while solving real operational constraints — chosen because our innovations and attitude meet customer needs.
Care
We've tailored our product to meet the unique energy needs of industrial process applications — moving beyond one-size-fits-all. We treat each other and our partners with deep respect, and actively seek out opportunities to learn and grow.
Trust
We are committed to consistency and stability in everything we build and every relationship we keep. Energy infrastructure should be reliable, clean, and built to last — for our customers, for each other, and for the world.
Frequently Asked Questions
Who founded FeX Energy and what is the team's background?
FeX Energy was founded by executive entrepreneurs, engineers, scientists, and operators with backgrounds spanning McGill University's Alternative Fuels Laboratory, Siemens Energy, Rolls-Royce, Caltech, and the University of Cambridge. The leadership team combines deep thermochemical research expertise with commercial energy deployment experience, bridging the gap between lab-proven science and industrial-scale systems.
What is the scientific basis behind FeX Energy's technology?
The Iron Arc Reactor technology originated from over fifteen years of research at McGill University's Alternative Fuels Laboratory, led by Professor Jeffrey Bergthorson, one of the world's leading researchers in alternative fuels and combustion science. FeX was built to translate that peer-reviewed, institutionally validated research into commercial energy infrastructure.
Who backs FeX Energy institutionally?
FeX is supported by research and industrial partners including McGill University, Fathom Fund, Antares Ventures, Amplify Capital, Hard Climate, the Canadian Department of National Defense, Exergy Solutions, and others. This mix of academic, industrial, and investment partners reflects the breadth of validation the technology has received across scientific and commercial domains.
Is FeX Energy actively hiring?
FeX Energy is building the team required to take iron-based thermochemical storage from pilot to commercial deployment. The company is looking for engineers, commercial leads, and operators who want to work on one of the harder, more consequential problems in industrial decarbonization. Details are available through the contact page.
How does FeX's team approach the challenge of industrial decarbonization?
The FeX team operates under four core principles: Impact, building technology that reduces industrial emissions while solving real operational constraints; Care, designing systems for demanding industrial environments; and Trust, treating relationships as something that must be honored, delivering dependably, and built to last. The team draws on hands-on field experience alongside research credentials.
What makes FeX Energy credible as an early-stage energy company?
FeX's technology is grounded in over fifteen years of peer-reviewed university research, validated through techno-economic analyses across multiple industrial verticals, and supported by institutional partners with deep energy sector experience. The Development Partnership program, partially financed by FeX with a host site already secured, provides a structured, low-risk path for early adopters to validate the technology against their specific operational needs.
