Challenges and Opportunities in CO2 Sequestration

An "impressive" 500 million tons/year of capacity for carbon capture utilization and sequestration (CCUS) projects in the United States are on the drawing board, designed to trap emissions from natural gas and oil projects. Those ambitions, though, have been tempered by uncertainties that include permitting challenges and public opposition. NGI's Carolyn Davis, managing editor of news, discussed the status of the domestic CCUS sector with Enverus Intelligence Research's CCUS expert Graham Bain, who leads the subsurface group for the energy transition team. The supermajors – including ExxonMobil, Chevron Corp., Equinor SA and TotalEnergies SE – are bankrolling several big projects, mostly in Louisiana and Texas. As Bain explained, if all the U.S. projects now in the queue were to be sanctioned, it would require an overall investment of $73 billion, with nearly one-half poured into carbon technologies and nearly one-third into carbon dioxide pipelines. The challenges are big, but the opportunities are too, he explains.
