Capturing CO2 from semi truck emissions.

Big Picture

Heavy-duty trucks move 70% of goods shipped in the United States. All this driving around emits more than 7% of US greenhouse gas pollution and represents a big chunk of Scope 1, 2, and 3 emissions for all manner of companies. As a growing number of businesses declare carbon targets, they run into the possibility that hydrogen and electric trucks may never offer a path to bring down emissions in time. 

How it Works

Remora’s device mounts between the cab and trailer of semi trucks. They use a solid sorbent that selectively binds with CO2 molecules in the exhaust stream without clogging it up. The sorbent regenerates freely using exhaust heat, releasing high-purity compressed CO2 in the process. Trucks offload the gas in the time it takes to refuel, allowing it to be sold for use or pumped underground. 

Unfair Advantage

Their mobile carbon capture system reduces emissions from semi trucks by at least 80% with limited impacts on payload, range, or trip time. Using biofuel or synthetic fuels, trucks could even run carbon-negative. Other technologies may hold the promise of decarbonizing semi trucks, but they are far off and expensive. Remora offers customers a low-capex approach to decarbonize entire fleets today.

Christina invented Remora’s technology during her PhD at the University of Michigan, becoming one of the world’s leading experts on mobile carbon capture.


Eric earned his master’s degree in mechanical engineering from the University of Michigan, and has built hydrogen and battery electric semi trucks for some of the largest automotive companies in the world.
