Where a suitable geologic formation for secure CO2 storage does not underlie an emissions source, captured CO2 will need to be transported to a separate location for injection underground.Transporting CO2 from a capture facility to a sequestration site is the easiest part of the CO2 emissions mitigation challenge. Pipelines appear to be the best and cheapest way to transport CO2 at substantial volumes. CO2 pipelines are already in commercial use, with about 3500 miles of underground pipe in North America used to transport CO2 from natural reservoirs to oil fields to enhance production (EOR). These pipelines have operated for years without significant safety incidents. CO2 pipeline technology is similar to that used for natural gas; accordingly, a robust construction, operation, and maintenance infrastructure is in place. And because of EOR applications, many pipeline-related regulatory issues have been addressed.
