If I read this correctly, this is mostly aimed at the smoke-stacks of fossil fuel plants. Great for reducing their harm before we phase them out, and valuable especially if it is cheap enough to actually be plausible. Cheap here matter more than perfect, since the problem of emitting CO2 from fossil fuel plants is better (but more slowly) solved by phasing out fossil fuel.
But how does this work for scrubbing CO2 from general atmosphere, is it anywhere close to an option? Once we have 'solved' the problem of no longer emitting CO2, we will almost certainly still have way more CO2 in the atmosphere than we want. Does this new scrubber material make it feasible to reduce the CO2 from the atmosphere, or will it be more economical to deal with the symptoms of high CO2 levels?
