Is it not possible that we find a way to scrub carbon straight out of the atmosphere and trap it underground? I don't know, and would be happy to pointed towards research on this, but it doesn't strike me as a simple energy-in-energy-out situation. There seems to be the potential for a brilliant technological solution.
- gshdg 6y agoThey’re called trees.
- FooHentai 6y agoNot really - By converting pasture back to woodland you could potentially restore some of the released carbon from agriculture-driven destruction of old forest land. But it won't make up for the vast reserves of carbon that have been dredged up from deep underground and released to the atmosphere. If it's necessary to re-balance that withdrawal we're going to need to put something back down there, or come up with something novel.
- gshdg 6y agoAFAIK, every other method requires massive electricity input; and we’re still not getting enough energy from renewables for that not to mean spewing more additional carbon than we sequester for each unit sequestered. (Of course, trees also require massive energy input. The difference is that we don’t have to supply that energy.)
- n4r9 6y agoWhich leads back to my question: is it not possible that we may find a technological alternative to trees which scales better and does not require us to supply so much energy.
- gshdg 6y agoI suspect the chemistry of it requires as much energy put into sequestering as is captured by releasing it. But... I could be wrong.
