USA: The start-up Remora, founded in 2020, and operator Pacific Harbor Line (PHL) have signed an agreement to jointly develop this technology.
PHL expects it to enable older locomotives to comply with the Tier 4 environmental standard and to sell the captured carbon dioxide to third-party clients.

The technology involves a special tender, which is connected to the locomotive’s exhaust pipe via a flexible hose. Inside, CO₂ is captured using a solid sorbent and then liquefied into a 20-foot tank container. The system is forecast to reduce emissions by 85%. CO₂ extraction is planned to be performed simultaneously with refuelling, and the servicing schedule of the tender will be synchronised with the locomotives’ operating cycles. A total of $117 mln has been raised for development, which also includes solutions for road vehicles. Prototype trials are planned for 2026.
In 2022, another American start-up, CO2Rail, presented a concept for a wagon to absorb CO₂ emissions, but the project has not yet been implemented.
