Texas Regulator Approves ExxonMobil Rose CCS Project with 5 Million Tonne CO2 Storage Capacity

Texas regulators approved ExxonMobil's Rose carbon capture and storage project, a 5 million metric ton per year CO2 storage operation in Jefferson County. The Railroad Commission voted 2-1 in favor, with one commissioner citing unresolved safety questions. The project will use three Class VI injection wells and includes a monitoring, reporting, and verification plan approved by the EPA. ExxonMobil plans to store CO2 between 0.5 and 1.5 miles underground in the Fleming and Upper Frio formations, with an 18-mile pipeline to connect captured emissions. The project is set on 13,000 acres and includes water monitoring wells. The EPA's approval notes the formations have suitable porosity and sealing layers, and corrective actions were taken on legacy wells to protect groundwater. This approval is a significant step for CCS deployment in Texas, but questions about long-term safety and economic viability remain. The dissenting commissioner's concerns highlight the ongoing debate over the role of carbon capture in emissions reduction. The project's success will depend on actual injection performance and cost.

Texas just approved ExxonMobil's Rose CCS project, up to 5 million tonnes of CO2 per year. That's a big number but the real test is whether the stored CO2 stays underground and if the economics hold without subsidies. Worth reading the MRV plan details.

The 2-1 vote is interesting. One commissioner voted no, citing safety concerns. The MRV plan mentions fixing legacy wells and monitoring, but I want to see actual injection data once it runs. Also, who pays for the 18-mile pipeline? That's a key cost.

This sets a precedent for Class VI permits in Texas. The EPA approved the MRV plan, but the dissenting commissioner's question about the point of CCS shows public trust is still shaky. The incentives and liability framework will decide if CCS scales or stays niche.

Approval for a 5 Mtpa CCS project in Southeast Texas. The plan includes three injection wells and monitoring, with storage between 0.5 and 1.5 miles deep. Good to see legacy wells addressed. But the real impact depends on how much of that capacity gets used.
