    There is biochar which can be scaled by providing cheap pyrolysis retorts and training how to bioactivate it. Incentive is increased agriculture productivity long-term. Capture should be done directly from flue gas since not needing enrichment. There are also carbon-negative concretes which have good potential for capture.

    Synfuels from 100% renewable are at least carbon neutral, which is as good as it gets.

      that’s not taking carbon from the atmosphere, that’s just carbon left behind from burning organic materials. That’s emitting CO2.
