Let's say I want to dump renewable surplus during peak (wind on a gushy day or a sunny midday) into methane (via Sabatier) or methanol. Nothing against plants (I heat with seasoned hardwood) but they don't harvest themselves, reseed themselves, deliver themselves as gas or liquid so that I can feed them to a plant (the chemical kind). So energy-efficient CO2 scrubbers from air or flue gas are quite interesting. Particularly, if you want to push for higher efficiencies (plants are typically less than 1% efficient in terms of biomass fixation).
