Norfolk Southern announced a groundbreaking pilot project using a rail car to capture emissions.

The railroad company will partner with start-up Remora in a project that places a tender car behind a locomotive to scrub emissions, preventing them from entering the atmosphere.

The first car could reach the tracks by late summer and full production could start in 2026, according to a press release. The project will help Norfolk Southern achieve its sustainability targets, including a 42% reduction in scope 1 and 2 emissions by 2034.

The new technology is built to capture 70% of carbon dioxide and reduce other air pollutants by 90% without affecting the train’s power. With it, locomotive exhaust enters a containment system allowing CO2 to be stored as liquid and is easily offloaded when the locomotive refuels. The carbon is transported to end-users like concrete, fuel, and chemical producers for purchase.

Remora, a carbon capture company, is working with Norfolk Southern and companies such as Union Pacific and Pacific Harbor Line, with revenue from carbon sales shared with the group.

By 2030, Remora plans to produce 500 units annually or lower 714,000 metric tons of CO2 annually.

Transportation is the largest contributor to emissions. Shipping by rail versus truck can reduce emissions on average by 75%.
