One note about Climeworks is that Climeworks only operates the carbon capture part of CCS. Climeworks can not store the carbon themselves so they rely on re-use of the carbon, or buying storage from other companies, mostly Carbfix (afik). Carbfix, has been researching the storage part for a while now, and they plan to import CO2 to their facilities in Iceland with tankers from European polluters (crazy idea, but apparently works out).
