Carbon capture for vehicles
Backed by Y Combinator · Neo
We're building carbon capture for trains and trucks. We generate revenue for railroads and trucking companies by extracting, purifying, and selling CO2 from their exhaust. Our technology can capture up to 90% of the CO2 in the vehicle's exhaust while reducing soot, particulate matter, and NOx. We've partnered with Union Pacific, Norfolk Southern, Ryder, and Werner, and raised $117 million from Lowercarbon Capital, Valor Equity Partners, Union Square Ventures, and Y Combinator.
Remora retrofit systems enable carbon capture on locomotives and semi-trucks, extracting and purifying CO2 from exhaust and selling it to end-users while sharing revenue with operators. The approach aims to monetize vehicle emissions by turning CO2 into a revenue stream for railroads and trucking companies. The company envisions future sequestration of CO2 underground or in end-user applications.
Remora retrofits locomotives and semi-trucks with zero-backpressure carbon capture. The system extracts and purifies up to 90% of the CO2 from the exhaust, while reducing soot, particulate matter, and NOx to meet Tier 4 standards. The purified CO2 is sold to end-users, and revenue is shared with the railroad or trucking company. When CO2 offloads at a distribution center or truck stop fills up, Remora transports the CO2 with tanker trucks to concrete producers or other end-users for permanent sequestration, with a target that the device pays for itself in a few years. In the future, Remora plans to underground storage in EPA-certified injection wells.
Who it’s for: Railroads and trucking companies operating locomotives and semi-trucks that emit CO2 and are seeking to monetize or reduce emissions.

Before Remora, I ran large-scale randomized experiments that uncovered new ways to increase political participation and bipartisanship. I first experienced the joys of carbon-neutral transportation during a solo bicycle trip across the US before college.
