carbon dioxide removal

“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…”

“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.”

“Some of the more expensive methods, like direct air capture, are gonna probably be easier to verify. And some of the potentially cheaper methods, especially those using biomass, are probably gonna be harder to verify.”

“Eventually it needs to get there, I think. It's going to be really bumpy and sloppy on the way. Long-term fullness of time, CDR needs to become a commodity market. I don't think there's a mechanism to scale it otherwise.”

“One thing that I found a little more useful is to kind of just think about like, what's the actual trapping mechanism for the CO two? Like where does the carbon actually end up? And there you can sort of think like, okay, well, it's leaving the air and another…”

“I do not think personally that in the 20 years are going to be enough to scale CDR solutions in a really, in a way that would really make an impact.”

“With CDR in particular, I think we would do well to really recognize this as essentially a depletable resource in some ways. You know, there's an amount of CO₂ in the atmosphere that means we're not going to run out anytime, you know, in the foreseeable future…”

“The reason for that is, the way that I Think about CDR is that you're looking, your mythical unicorn solution for removing CO two from the atmosphere has four characteristics. It is cheap, which is, you know, let's just call it sub a hundred dollars a ton, but…”

“Like, loudest, most conservative scientist in the room-based governance doesn't work for this. You actually do need to make something off-takeable and contractable, and the way you do that is for these emerging more uncertain approaches, or the approaches that…”
