A CO2 capture solvent with exceptionally low total costs of capture
For making a dent in global warming we'll need to have billions of tonnes of this "N-(2-ethoxyethyl)-3-morpholinopropan-1-amine (2-EEMPA)" stuff..I wonder if this won't be an environmental hazard in itself. What do we do with it after it's captured its CO2? We can't just dump that stuff in the sea.I wonder if CO2 capture does not cause more problems than it solves. Even if we magically could capture CO2 as pure carbon and let the O2 back into the air, we'd end up with enough carbon to fill all the mines we've emptied over the years. Where are we going to leave all that without making a huge environmental mess? And how do we transport all that there? And that's not even considering the energy usage and possible reagents.I think we should really reduce our energy usage instead. Every tonne of CO2 not emitted does not have to be captured, and the effects of not producing it are positive for the environment in more ways than just global warming.Of course we're already on a path for significant global warming, but I think we'll just have to deal with that as we go. I don't think we'll manage to do significant CO2 capture before the effects are irreversible anyway.
