Not sure if it's the same stuff exactly or if the cost includes reprocessing but there's an amine cycle that seems to be mostly closed that's used for CO2 removal on submarines. So it's just used to separate CO2 from the rest of the output. I think that's what this sentence is talking about: > Notably, it is projected that this solvent can operate at a regeneration heat rate of 2.0 GJ per tonne CO2 for post-combustion capture Smarter Every Day did a video on it and atmosphere management on a submarine more generally which is pretty neat. The CO2 scrubbing is around 20 minutes. https://www.youtube.com/watch?v=g3Ud6mHdhlQ https://www.youtube.com/watch?v=g3Ud6mHdhlQ
