Company Overview
About Remora
Remora is a Detroit-based climate technology company building carbon capture devices that attach to semi trucks and freight trains — capturing CO2 from diesel exhaust while simultaneously reducing soot, particulate matter, and NOx by up to 90%, then purifying and selling the captured CO2 to industrial buyers. Founded and a Y Combinator W21 graduate, Remora raised $117 million from Lowercarbon Capital, Valor Equity Partners, Union Square Ventures, and Y Combinator (Series A in February 2024), with partnerships established with Union Pacific, Norfolk Southern, Ryder, and Werner Enterprises.
Business Model & Competitive Advantage
Remora's hardware device attaches to the exhaust system of diesel trucks and locomotives — as exhaust passes through the capture unit, CO2 is extracted through a chemical absorption process, compressed and stored on the vehicle, then offloaded at truck stops or rail facilities where the CO2 is purified for commercial sale. The commercial CO2 market ($3-7 per ton for industrial CO2) provides revenue that partially offsets the device cost, creating a business model where trucking fleets eventually profit from the carbon capture rather than treating it purely as a cost center. The simultaneous reduction in particulate emissions provides health benefits in freight corridors.
Competitive Landscape 2025–2026
In 2025, Remora competes in the carbon capture and industrial decarbonization market with CarbonCapture, Climeworks (direct air capture), and the nascent trucking electrification alternative (Tesla Semi, Daimler eActros) for long-haul freight decarbonization. The long-haul trucking market is one of the most difficult to decarbonize — battery-electric trucks lack the range and charging infrastructure for most freight routes, and hydrogen trucking is still early. Remora's approach of making existing diesel trucks cleaner while they remain in service addresses the practical reality that the current fleet will remain in operation for 15-20 years regardless of electrification trends. Union Pacific and Norfolk Southern partnerships validate the rail application alongside trucking. The 2025 strategy focuses on scaling device manufacturing and deployment, building out the CO2 offtake infrastructure, and demonstrating the economics of carbon capture as a profit center for fleet operators.
