How does the technology from Prometheus count as carbon recapture? We end up taking a (relative to the size of the problem) small amount of the 'extra' carbon out of the atmosphere... and then proceed to burn it and put it right back in. IMO carbon recapture only counts if the carbon gets removed permanently. But Prometheus's technology is problematic for other reasons. Let's say that all of the $3/gallon which was quoted can be attributed to electricity cost and nothing else. At $0.12/kWh that would be turning 25kWh of electrical energy into ~36kWh of chemical energy (gasoline). Now it needs to be transported to the gas station, which costs something like 10% of the total energy content. So now we're back to ~32kWh of chemical energy delivered to the customer. They convert it into mechanical energy at 20% efficiency [1]. So you've converted 25kWh of electrical energy into 6.5kWh of mechanical energy at the customer's wheels. Meanwhile, we would be using a fuel that is interchangeable with carbon we dig out of the ground. What are the chances we limit ourselves to only the "green gasoline" and ignore the stuff in the ground? Meanwhile electric vehicles convert ~60% [1] of the electrical energy used to charge them into mechanical energy. So you convert that 25kWh into 15kWh of mechanical energy. Energy can be generated in many ways, many of them not very green at all. Let's assume both the "green gasoline machine" and the EV charging box are powered by the same grid. You could go 2.3x as far with the EV for the same energy input. Now if Prometheus is making "green jet fuel" I'd be interested because there isn't any obvious electrification solution to long distance air travel that seems close to commercialization.
