I wouldn't call Fischer-Tropsch a "high temperature" process at least compared to other processes that run at an oil refinery. A big problem with it (unless you're making methane) is that high temperatures break hydrocarbons down.

Low temperature processes run at a low rate so you have a huge machine and large quantities of catalysts tied up to make just a trickle of fuel.

Nice to see the F-T process bypassed because the high capital cost makes it the last refuge of the desperate.

Prometheus should be laser focused on being first to market in commercial quantities. There are people who want carbon neutral fuels today even if they are more expensive than fossil fuels. Capture that entire market with v1 of the process even if it's $10/gallon. Take everything learned to make v2 at $7/gallon and v3 at $5/gallon etc...

The goal of $3/gallon is pushing Prometheus down the rabbit hole. Waiting for the perfect factory, with the manufacturing methods, to produce the perfect machine that will immediately go into large scale production, and operate on an automated basis. I expect the company aiming at 10-7-5-3 will reach 3 there faster than the company aiming at 3 to start out with.

Can someone explain how this is carbon neutral? It sounds like it produces regular gas, but using electricity instead of extracting petroleum. Wouldn't burning the gas produced still be a problem?

They acquire the carbon using direct air capture[1]

Due to Russian oil drying up volatile high prices globally will be the norm until technology like this comes into play and at least puts a ceiling on the price. So, the real question is how quickly and how cheaply can they reach 4 million barrels per day of production?

They catch CO2 from air. They make fuel only from this and electricity. Then once someone burns the fuel, it produces the same or less CO2.

This seems like a plan that's contingent on the moonshot of extremely cheap and scalable carbon capture. So far, effective carbon capture has remained elusive. "Carbon offsets" really means signing papers where a country says "we would have cut down this forest, but we won't now that you paid us." Actually taking carbon out of the atmosphere and burying it is the stuff of prototypes.
