  It's not entirely dishonest, but it's a huge caveat that their process has 2 parts with an intermediate, so comparing just one part to other processes doesn't make sense. E.g. in one section, they mention that DAC to CO2 is targeted at $100/ton, but their process is only $36/ton. However, that's only the first half of the process. If you calculate for the whole process and assume they can produce a standard gallon of gas for $3 and 8.9 Kg CO2/gallon: ($3/gallon) / (8.9 Kg/gallon) * (907 Kg/ton) = $306/ton I.e. their goal is 3x more expensive at capturing CO2 than DAC. If you want to sequester carbon (e.g. by filling a cavern with this fuel), this is not the technique to use. The only reason to pursue this is to use zero carbon electricity to produce nearly net-zero carbon fuel.

      And it's pretty much good enough; 90% of carbon emissions are from fossil fuels, 90% of that is petroleum products. If we could get half of our gasoline to come from Prometheus in the next ten years, that would be the EU emissions goal. Done. That's it.
