“If somebody tells you that we absolutely need CCS for steel, that's just not the case.”

Bataille: Enhanced oil recovery is the first major use for captured CO2
“The first biggest use if you're going to do CCU is actually enhanced oil recovery in place of other higher emitting oil sources as we climb down from a hundred million barrels a day down to zero sometime mid-century. But, you know, obviously that's a contentio…”
Bataille: Over 90% of captured CO2 must be permanently stored, not utilized
“The numbers I typically see is we will utilize less than 10% of it. Most of it has to go into deep storage, be it depleted oil and gas reservoirs with tight overseal, or into deep saline aquifers. Like, the vast majority has to go into permanent storage withou…”
Bataille: CCS is essential for cement due to lack of alternative chemistries
“We're going to need it for cement because there are no alternative chemistries coming down the pipe anytime soon, and there's a lot of buildings that need to be built.”
Bataille: Permian methane leak rates make natural gas as dirty as coal
“In places like the Permian where, you know, the number is seven percent, then eight percent, then nine percent, those are tragically high fugitive, fugitive, fugitive levels. You might as well be doing coal.”
Bataille: Carbon removal is an admission we will miss net-zero targets
“We're probably going to blow past the deadline by about two decades, which means, you know, CDR is basically an admission of failure. That we did not mitigate fast enough.”
Bataille: Technical carbon dioxide removal will reach 1 to 5 gigatons annually
“The key CDR technologies, in my mind, will be direct air capture with CCS, because what CCS does is it takes the CO₂ taken by the direct air capture unit and pushes it back underground, and probably some forms of geological weathering, and it's going to be a b…”
