> Using CO2 from an industrial point source is more efficient; however, it has potential legislative issues when it comes to certification of sustainable fuels, emission certificate trading... it's a fairly complicated topic.

I can imagine! Considering lots of the co2 in air has fossil fuel origin, not putting the co2 capturing at a high volume co2 source seems rather dim. Regulators gonna regulate!

Maybe site the direct air capture in the middle of a german industrial city with coal plants all around...

Or even better, at an airport. Then you have nil transportation cost for delivery too.

Something like this could create a large market for CO2. If the market was hot enough, fossil fuel plants might capture and sell their own emissions.
