The pipelines are dominant mode of transporting CO2 in US and account for 90% of CO2 transported in dense state. it is therefore first compressed as a gas and then pumped in a super-critical state (Temperature ~ 88 oF & Pressure ~ 1070 psia)  at significantly higher pressures than natural gas.  Transportation of CO2 through pipeline is established in USA

What Are the Issues & Challenges in Transporting CO2 in CCS projects?

We can provide a transportation overview to demystify the challenges before you start CCS project

​

• There are 50+ CO2 pipelines operating in USA currently pumping about 68 mtpa

• Most of CO2 pumped in US is sourced from natural CO2 reservoirs in Colorado, N Mexico & Wyoming

• US has nearly 5000 miles of CO2 pipeline Newark compared to 800,000 miles of natural gas

• CO2 pipeline are dedicated and cost & design depends on volume, pressure and distance

• CO2 PL cost account as much as 25% of total CCS project cost (pipeline, compression & pumping)

• CO2 tariffs are rarely quoted and most often negotiated between parties

• Infrastructure projects, linking hub & clusters of sources & sinks can reduce transportation cost
