The Railroad Commission of Texas (RRC) has approved Class VI injection permits for ExxonMobil ’s Rose carbon capture and storage (CCS) project in a 2-1 vote, overcoming internal dissent over long-term geological safety and project economics.
Located in Jefferson County, approximately 15 miles southwest of Beaumont, the Rose project targets the permanent underground injection of 53 million metric tons of CO2 over a 13-year period. ExxonMobil plans to inject roughly 4 million tons annually from surrounding industrial sources into the regional Fleming and Upper Frio rock formations.
The approval includes three Class VI injection wells and requires active site monitoring throughout the 13-year operational window and for 50 years post-injection, or until regulators confirm nearby drinking water sources remain protected.
Technical Dissent and Subsidy Pushback
Despite the majority vote, Railroad Commissioner Wayne Christian voted against the permit, citing unresolved technical risks regarding potential groundwater contamination and CO2 migration through unmapped subsurface faults.
Christian pointed to proceeding testimony questioning whether interbedded sand zones in the project’s upper confining layer could ensure a secure seal, while arguing that the proposed groundwater monitoring framework left critical depth intervals exposed.
“I remain unconvinced that the record adequately establishes the project’s long-term safety,” Christian stated following the vote. “I still have not heard a convincing answer to a basic question: What is the point of permanently injecting carbon dioxide underground?”
Christian also criticized the federal 45Q tax credit, arguing that government subsidies distort energy markets to support projects that fail to compete on independent economics.

In response, ExxonMobil maintained that extensive geological modeling and site characterization confirm the location’s structural integrity, noting that identified risks are fully mitigated through the project’s engineering design and operational monitoring plan.
“Today’s decision is a major milestone for the state of Texas,” Exxon said in an official statement.
“The Railroad Commission clearly recognizes the important role carbon capture and storage can play in meeting growing global demand for lower-carbon products while supporting new jobs and economic growth. We look forward to building on this momentum as we continue expanding our CCS business across the US Gulf Coast.”
