I understand you perfectly. I just don't agree with a single sentence of it. The semantics of carbon capture for you seem to mean to capture some (tiny) percentage of the absolutely epic levels of fossil carbon we put into it today.
The point of Prometeus is to take no fossil carbon whatsoever (0%) and create the fuel directly from the CO2 already in the air and indeed put it back there when it is burned. It's not capturing so much as reusing what is already there. It's by definition the most efficient way. It's 100% efficient.
None of the things you listed actually produce fuel. So they are 0% efficient. At best they offset some meaningless percentage of fossil fuels. Actually raising the cost of those fossil fuels to pay for more meaningful percentages (like more than 1 digit?), just strengthens the business case for Prometheus. The more costly fossil fuel gets, the more attractive Prometheus gets. As it is, they seem to be claiming to be cost effective as is.

Okay. Invest in Prometheus. I think the net result will be an increase in CO2 emissions, because all the activity will fail to deliver any viable atmospheric CO2 capture plants, ever. Let's check on this say 20 years from now. If I'm right, buy me a beer.
