“According to Exxon’s own disclosures and an analysis conducted by IEEFA in 2022, only around 3 percent of the carbon captured there (roughly 6 million tonnes) has been permanently sequestered underground. Of the rest of the 240 million tonnes of carbon emitted over the facility’s first 35 years in operation, half has been sold to various oilfield operators for enhanced oil recovery, or EOR — a process by which oil companies inject carbon underground to get more oil out — and approximately 120 million tonnes has been vented into the atmosphere.”

“When CO2 is actually sequestered underground, there’s no guarantee it stays there. “CO2 has a way of moving through the air, of leaking through pipelines, and because we have no cradle-to-grave tracking, we have no way of actually knowing how much is leaking, how much is really being collected, how much is hitting the wellhead, and how much is really staying underground,” Raffensperger said.
That’s not just concerning from a climate perspective, but from a public health perspective as well. Raffensperger notes that the pipelines built to transport condensed carbon from oil fields to storage facilities, or to other oil fields for EOR, are surrounded by “kill zones.”

“These are not your grandmother’s pipelines,” Raffensperger said. “They could be lethal. We talk about the kill zone or a fatality zone around a CO2 pipeline. We don’t talk about that with oil and gas pipelines. These are uniquely dangerous and underregulated.”

Following a 2020 CO2 leak and explosion in Satartia, Mississippi, that abruptly stopped cars on roadways, caused widespread dizziness and nausea, and sent several residents to the hospital, the federal Pipeline and Hazardous Materials Safety Administration began looking into rules for CO2 pipelines. They were set to finalize that rule this summer, pending review by the Office of Management and Budget and the Office of Information and Regulatory Affairs, but that deadline has been extended to fall 2024. The lack of finalized safety regulations has not stopped the permitting of CO2 pipelines, though. The Summit pipeline, a massive project that would carry carbon across five states, just got the go-ahead in June for the first step of its construction process in Iowa: seizing land through eminent domain to make way for the pipeline.”

“Fatih Birol, executive director of the International Energy Agency, has called the industry’s plan to offset its emissions with carbon capture “fantasy.”

But the US government is all in on that fantasy now.

“[The carbon capture tax credit] 45Q is not based on net climate benefit or net CO2 reductions, it’s based on gross CO2 capture,” Blackburn, the environmental lawyer, said. “Why would you think making carbon a commodity would reduce CO2 emissions? It’s like the opposite of carbon tax, we’re actually paying them to produce more of it.””
