Yeah, concentrating CO2 from atmospheric concentrations is not easy. The benefit is that it actually removes carbon from the atmosphere. Whether it can ever be done on a large scale is a question, though. Is there any work on doing that, at a low energy cost? (I mean concentrating CO2, not removing it by weathering rocks?) Yeah, ships are not really weight constrained, unlike airplanes, really cheap sodium batteries should be feasible. |
