So, I think you hit the nail on the head, Gabe, is there's a lot of people looking at various types of CCUS from ranging from air capture to stack capture, to almost things dealing with some conventional recycling of tertiary recovery type of project. So, it's kind of across the map. It's very early in the project development. We remain somewhat guarded as to the feasibility of this. To compress CO2, requires some technical changes. Typically, you're looking at some higher pressures instead of a three-stage unit. You might need a five-stage unit because you're injecting gas at a significantly higher discharge pressure, you need single steel on a lot of the piping. You can't have any what we call yellow metal or red metal -- brass and bronze and things like that because the CO2 will unbridle and the equipment will fail. CO2, with any kind of water vapor, formed carbonic acid, which is highly corrosive. So, you have to take all of that in your design consideration. So, we're starting to see more and more interest, but have they actually moved forward to FID, Final Investment Decision. Jury is still out yet. It's very early. I mean, we're kind of in the beginning of the first inning, not even mid-innings, as to the -- is this really going to occur? So, like everything ESG-driven, we think a lot of it is going to be regulatory driven, and obviously, here, over the last year or so, there have been some significant alteration in the current regime's outlook on carbon and CO2 and carbon taxes and incentives or disincentive. So, economics aren't quite there yet. And I think that's what people are waiting to see is, let's test the waters, let's be ready to move, if it makes sense. And until it makes economic sense, there probably will be some continued can taking, so to speak.
