Germany will soon have planes dropping out of the sky at the fastest rate since the Battle of Britain. Zing!
The Germans invented the means to make synthetic fuels. They are the world leaders in it. During WWII nearly every drop they used was synthetic millions and millions of gallons on a scale that humans had not seen and since. They export their technology the South Africans use it every day to make millions of gallons of jet fuel, diesel and petrol. This process adds a step to well established economically viable technology. Instead of using coal or natural gas to generate singed(CO,H2) in a one to two ratio they are using CO2 and cracking that to the carbon monoxide CO and then cracking water H2O to H2 the hydrogen they need from that point forwards it’s 1930s technology that the Germans rule the world in. The question is what’s the cost per gigajoule to crack CO2 , water electrolysis is well established industrial process with known cost metrics.
The Navy as in the U.S. Navy has been testing making fuels from seawater for the C,O2 and H2 for years they flew an F18 on it a few years ago. The plan is to use the carriers nukes to crack the seawater into fuel. They have the cost at $6 per gallon which is cheap compared to underway replenishment by a fleet oiler shipping fuel half way around the planet into a contested waters. The cost for oiler delivered fuels has hit $400 a gallon and avg over $25 all those numbers are available by the GAO.gov btw.
