ExxonMobil has won approval for a Texas carbon capture permit, clearing a regulatory hurdle for injecting CO2 underground. The permit matters because large-scale CCS projects need storage rights and monitoring plans before they can operate. For carbon markets, the question is whether stored CO2 gets measured and verified in a way that supports credits or 45Q tax incentives. Texas has become a test bed for carbon capture because of its geology and existing oil and gas infrastructure. But a permit does not guarantee a project moves forward. Capture costs, energy use, and long-term liability still determine whether the project makes economic sense. Investors should watch for details on injection rates, monitoring frequency, and who assumes responsibility for leaks.
