As new CO2 sources and demand centres emerge across North America, the ability to connect the two is becoming increasingly important. For Kari Wagner of Greenbrier, rail could provide one of the missing links.
Speaking to gasworld at the North American CO2 Summit 2026, Wagner discussed the growing opportunity to transport CO2 by rail, particularly over longer distances where pipeline infrastructure is unavailable.
Wagner explains how rail can help overcome the regional nature of today’s CO2 supply, allowing product from new capture projects to reach markets further afield. With new sources emerging across areas including ethanol, power generation and data centres, she sees rail as a way of connecting that supply with both established CO2 demand and emerging applications such as e-methanol and sustainable aviation fuel (SAF) production.
One of the challenges of transporting CO2 by rail has been product loss but Wagner explains how Greenbrier has applied technology from other railcar types to extend the time CO2 can be transported without product loss.
The conversation also explores what companies need to consider when looking to move CO2 by rail, from working with local railroads to securing the necessary railcars and logistics support.
