“And cement, just the process of making it fundamentally results in CO₂ emissions, even if you did full energy switching, efficiency, all that kind of thing. Basically you're cooking limestone that drives off CO two.”

Opinion
Emily Grubert: Cement may be the only sector where CCS is indispensable
“I think with regard to this category of CCS, I sometimes can convince myself that cement might be the only thing in this category where you need CCS to mitigate emissions from something.”

Emily Grubert: Carbon removal is a depletable resource due to physical constraints
“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 idea of maximizing now because you're going to need the infrastructure anyway fails, I think, in one major way, which is that it's not conscious of where that infrastructure needs to go. And in a situation where you're designing linear infrastructure like …”

“We don't really have the structures in place to ensure that that
Accounting is really happening, and looking at some of the project announcements or ideas that I've seen where both ends of the spectrum are kind of claiming the mitigation is challenging, especi…”

Opinion
Emily Grubert: Climate policy should minimize overall carbon capture and storage deployment
“So in my view, I think we need to at least try to get to a world that minimizes the amount of CCS that we're doing, whether that is for mitigation or removal, and basically just because it's infrastructurally intensive, it's energy intensive, all of these kind…”

“In practice, because this is mostly fossil stuff, I think that ends up looking a lot like lifespan extension or some way to keep using fossil fuels into a decarbonized future.”
