    It doesn’t matter, it’s carbon capture (from the stack, or air directly). These require energy we don’t have, even where there are smoke stacks.

      It absolutely does matter. This article is not about DAC, it is about carbon capture. They are entirely different processes.

      What goes into capturing and storing all of the concentrated GHG at the time of combustion at the site of energy production is entirely different than what goes in to pulling already-dispersed CO2 directly from the air. For one thing, carbon capture is necessarily powered by fossil fuels. DAC is virtually always renewable-powered because it makes zero sense otherwise.

      These terms have meaning. I understand they are confusing, which is why I clarified for you. When you said that carbon capture may “work eventually”, I now know you were talking about DAC. But that’s an entirely different thing that isn’t relevant.

      Carbon capture is a process for using fossil fuels without releasing GHG. It is not pulling CO2 from the atmosphere; that is a different thing. Almost certainly a total technological dead end not worth pursuing.

        Bro way to come in late to the conversation like anybody was talking to you.

        I responded to a comment that was talking about the technology itself, not the article. What I said still stands, go be pedantic somewhere else.

          You didn’t reply to a comment. Your post is top-level.

          You’re confused and defensive and don’t know what is going on here.

          And the “technology itself” is CCS, not DAC. It’s not the technology you think it is. Try to learn instead of being a jerk.

              What are you talking about, dude? This thread is about US Steel wanting to use CCS. Your post is top-level, you’ve been talking to me the whole time, and the only other thread here is the guy talking about Swiss steel projects that don’t use CCS nor DAC.

              Your original comment doesn’t mention DAC. It mentions carbon capture. I replied to you basically agreeing and saying I really didn’t think carbon capture has any actual application, at which point your reply showed you didn’t know that DAC and CCS/carbon capture are different things and has been using carbon capture to talk about DAC, so I explained the difference for you – because I know the terms confuse a lot of people. And you got defensive.

              Seriously, I encourage you to take a moment and look through this exchange from the beginning. Clearly it’s not worth continuing, but this is incredibly frustrating for me.
