US Navy 'game-changer': converting seawater into fuel

I didn't see a post about this, so I apologize if I missed it.

Very interesting if it turns out to be worth while. I wonder what kind of energy needs to go into the process and if it's at least neutral in that respect.

The US Navy believes it has finally worked out the solution to a problem that has intrigued scientists for decades: how to take seawater and use it as fuel.
The development of a liquid hydrocarbon fuel is being hailed as "a game-changer" because it would significantly shorten the supply chain, a weak link that makes any force easier to attack.

The ultimate goal is to eventually get away from the dependence on oil altogether, which would also mean the navy is no longer hostage to potential shortages of oil or fluctuations in its cost.

We do something similar right now in my family's recycling business. We turn discarded hydrocarbons into liquid and gaseous fuel.
Ten years is nothing.

Drawbacks? Only one, it seems: researchers warn it will be at least a decade before US ships are able to produce their own fuel on board.

Wonder if Snowden has turned this over to the Russian's yet?

The real game-changer is when that hits the civilian market. Within 50 years the Middle East will be fairly irrelevant.

Don't have time to research the energy technology.
Are they using hydrolysis to separate the water molecules into the base H2 & O atoms?

there was at least one hydrogen car that got through production, got good reviews (may have gotten bad ones as well, but I didn't hear any) but was scrapped before it made it to the showroom.

The US Navy is really on a PR/Marketing push these past two days.
They must need more/want to keep their funding.

This will never make it to the civilian world.
Governments cannot tax water like they can oil and gas.

This technology will never enter the civilian market. Big oil would never let it

How do you people even get out of bed in the morning?
IF this tech becomes cost effective..it WILL enter the market.

Using sea water would bring out the Greenies, and save the Whale type like never before, I mean why take water away from marine life?

This is a bit off-topic, but U.S. aircraft carriers and submarines can go 25 years before needing to be refueled. It's powered by uranium only the size of a fist. I thought that was incredible.

Pffft...think about the reduction of the "rising sea level due to GW"...this could be what saves our coastlines and all those island peeps

Be pretty hard to keep it out imho.
I suspect there are some devils in the details though.

But, the other vessels are not nuclear powered. Those vessels need this tech

annnnnnd - we could balance off GW with nuclear winter scenarios - seems like we got all the controls we need.

For sure.

OK, then it's perfect...lol!

Well,the USN now has 280 ships and only about 1/3 can be deployed at one time...we had around 600 in the height of the Reagan military buildup...

The NRL process begins by extracting carbon dioxide and hydrogen from seawater. As seawater passes through a specially built cell, it is subjected to a small electric current. This causes the seawater to exchange hydrogen ions produced at the anode with sodium ions. As a result, the seawater is acidified. Meanwhile, at the cathode, the water is reduced to hydrogen gas and sodium hydroxide is formed. The end product is hydrogen and carbon dioxide gas, and the sodium hydroxide is added to the leftover seawater to neutralize its acidity. In the next step, the hydrogen and carbon dioxide are passed into a heated reaction chamber with an iron catalyst. The gases combine and form long-chained unsaturated hydrocarbons with methane as a by-product. The unsaturated hydrocarbons are then made to form longer hydrocarbon molecules containing six to nine carbon atoms. Using a nickel-supported catalyst, these are then converted into jet fuel.
