CO2 removal (and storage) at scale is impossible. We would basically have to recreate the Azolla event: https://en.wikipedia.org/wiki/Azolla_event https://en.wikipedia.org/wiki/Azolla_event We already have condensed carbon - in the ground, stable, in the form of coal, natural gas, and oil. We need to just stop digging it out and burning it. There's really no getting around the need for a direct and transparent price on carbon. The health benefits from lower air pollution alone would probably pay for the transition itself. For example, at just about $15/tonne, coal is immediately dead (doubled in price) as an electricity source: https://www.resources.org/common-resources/calculating-various-fuel-prices-under-a-carbon-tax/ https://www.resources.org/common-resources/calculating-vario... Whereas current techniques are coming in at about $500/tonne for CO2 removal.
