I have been thinking along the same lines (same process for CO2 capture and natural gas as output). The thing that kills it is energy requirements, in this scenario 1 MW of solar panels would cost about 1 million USD + 100k USD for the plant. In theory it could be profitable within 7-8 years - possibly sooner if built in Africa or some other country with infinite solar (just napkin math).

Another thing that might make it more profitable is extra conversion to SAF (Sustainable Aviation Fuel).

Long term in this type of tech is crucial to stop burning up carbon stored in the ground for use cases that require more energy density (like flight).
