AFAIK, 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.)

Which 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.

I suspect the chemistry of it requires as much energy put into sequestering as is captured by releasing it. But... I could be wrong.
