Default Navy Claims It Can Turn Sea Water Into Jet Fuel

For 3-6 dollars a gallon. Maybe this is just propaganda?

The 3-6 dollars a gallon sounds like pie in the sky to me. The chemistry is out there to do this, but the amount of steps involved make it a fairly involved process. Gov agencies are not exactly known for their ability to streamline, optimize and economize things.

Hydrolysis of sea water is nothing new. Nor are catalytic reactions to cause H2 and CO2 to combine into hydrocarbons. So, I'm wondering what is the specific innovation here. Historically, hydrolysis has required more energy input than the amount of energy gained. If it didn't, we could just use hydrolysis all day to produce H2, which is much more energy dense as a fuel than hydrocarbons. The amount of CO2 in seawater is fairly small, so being able to liberate it as feedstock wouldn't really have much of an overall impact on things. Something does not add up here. There is zero coverage of this on Science Daily.
