ExxonMobil's sponsored post explains the basics of carbon capture and storage (CCS). It covers how CO2 is captured, transported, and injected into deep rock formations for permanent storage. The article emphasizes that CCS is a proven and regulated process that helps reduce emissions from essential industries like steel, cement, and fertilizer while supporting economic growth. The post also addresses monitoring and regulation, noting that Louisiana received EPA authority to regulate Class VI wells in 2023. It explains the Underground Injection Control program and the safety measures in place, including multiple layers of steel and cement to prevent leaks. Groundwater protection and property rights are covered, with CO2 injected far below drinking water aquifers. This is a sponsored explainer from ExxonMobil, so it presents a favorable view of CCS. It's useful for understanding the industry's perspective on CCS technology and regulatory frameworks.

This is a sponsored explainer, but it does cover the basics of CCS. The part about Louisiana getting EPA authority for Class VI wells is interesting. I'd like to see actual numbers on storage capacity or cost per ton, but that's not in this piece. Worth reading if you're new to CCS.

The article says CCS is 'proven' but doesn't talk about long-term liability or monitoring after injection ends. Who is responsible if a leak happens decades later? That's a key gap for me. Also, it doesn't mention the energy penalty of capture.

They say CO2 is injected far below drinking water and separated by impermeable layers. But how do they verify no leakage over time? Monitoring is mentioned but not the specifics. Also, what's the injection pressure and how does that affect seismic risk? Seems like a high-level overview.

The regulatory section is thin. Louisiana got primacy for Class VI, but the EPA still has oversight. The article makes it sound simple, but the permitting process is complex. Also, it doesn't address how CCS fits into carbon accounting or if it gets tax credits. That's a big piece missing.

For industrial heat, CCS is one option but it's expensive. The article mentions steel, cement, and fertilizer, but doesn't say anything about retrofitting existing plants. Payback periods matter. This reads like a PR piece, not a technical deep dive.
