Gas pipelines, CO2 pipelines, hydrogen pipelines?

economics of CO2 and hydrogen pipelines

This model captures the energy economics of gas pipelines, CO2 pipelines and hydrogen pipelines. Specifically, we have modelled energy requirements using simple fluid mechanics, and modelled capex costs using past…

CCS: what CO2 purity for transport and disposal?

CO2 purity required for various purposes. The highest purities are required by food, beverage, and medical purposes, as well as shipping and liquefaction. CO2 disposal has the highest variability. For any purpose the purity must still be at least 90%.

…CO2. But impurities require higher pressures before CO2 reaches supercriticality. Larger pipelines are also required to move larger quantities of gas at higher pressures. This matters because larger pipelines with…
