Shell, Air Liquide and BASF have become the latest major companies to join the CCS Innovation Zone project, which could become the world’s largest carbon capture and storage scheme. Based in the Houston area, the project envisages collecting carbon dioxide from sources such as power plants, plastic manufacturing facilities, and refineries along the Houston Ship Channel and the wider Texas Gulf Coast, injecting it offshore. Up to 50 million tonnes per year could be collected by 2030, and 100 mtpa by 2040, according to the planning for the project, which is in the evaluation stage. The Zone was first announced by ExxonMobil in April 2020, and has since been joined by Chevron, Marathon Petroleum, Phillips 66, Dow, INEOS, Linde, LyondellBasell, NRG Energy, and Calpine. As the Journal of Petroleum Technology notes, Shell’s entry into the project comes a few months after it learned it would not be the recipient of government funding for a CCS project in the state of Louisiana. There is at present no timeline for the rolling out of the next stages of the Zone.
