$FCEL: The Carbon Capture Trade Nobody’s Modeling Correctly

9 Ventures Equity Research · June 2026

$FCEL’s molten carbonate fuel cells have a property that almost nobody outside of technical circles understands: they can pull CO2 out of an industrial emitter’s exhaust stack and concentrate it for sequestration, while simultaneously generating more electricity than they consume. Not as a theoretical claim. As a documented result, independently confirmed by the IEA, the UK government, and in a peer-reviewed paper co-authored by ExxonMobil’s own engineers.

The market continues to price FuelCell as a subscale power generation company, even though we know that business is inflecting soon with a 5.5 GW data center pipeline and a 500 MW capacity expansion underway. The carbon capture business, which just shipped its first commercial modules to ExxonMobil’s Rotterdam refinery this month, is priced at roughly zero. The serviceable addressable market for this technology is $380-440 billion in installed equipment. At base case penetration, the annual revenue run-rate by 2040 is in the billions. FuelCell Energy did $158 million in total revenue last year.

The full analysis, including a decade of study results, the competitive picture, the Exxon commercial arrangement, all four revenue levers, and the capacity-constrained model we built from the ground up, is below for paid subscribers.
