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

Washington (AFP) - 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 signficantly shorten the supply chain, a weak link that makes any force easier to attack.

The US has a fleet of 15 military oil tankers, and only aircraft carriers and some submarines are equipped with nuclear propulsion.

All other vessels must frequently abandon their mission for a few hours to navigate in parallel with the tanker, a delicate operation, especially in bad weather.

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.

Vice Admiral Philip Cullom declared: "It's a huge milestone for us."

Dr. Heather Willauer explains how scientists at the Naval Research Laboratory in Washington, DC can …

"We are in very challenging times where we really do have to think in pretty innovative ways to look at how we create energy, how we value energy and how we consume it.

"We need to challenge the results of the assumptions that are the result of the last six decades of constant access to cheap, unlimited amounts of fuel," added Cullom.

"Basically, we've treated energy like air, something that's always there and that we don't worry about too much. But the reality is that we do have to worry about it."

US experts have found out how to extract carbon dioxide and hydrogen gas from seawater.

Then, using a catalytic converter, they transformed them into a fuel by a gas-to-liquids process. They hope the fuel will not only be able to power ships, but also planes.

That means instead of relying on tankers, ships will be able to produce fuel at sea.

- 'Game-changing' technology -

The predicted cost of jet fuel using the technology is in the range of three to six dollars per gallon, say experts at the US Naval Research Laboratory, who have already flown a model airplane with fuel produced from seawater.

Dr Heather Willauer, an research chemist who has spent nearly a decade on the project, can hardly hide her enthusiasm.

"For the first time we've been able to develop a technology to get CO2 and hydrogen from seawater simultaneously, that's a big breakthrough," she said, adding that the fuel "doesn't look or smell very different."

Now that they have demonstrated it can work, the next step is to produce it in industrial quantities. But before that, in partnership with several universities, the experts want to improve the amount of CO2 and hydrogen they can capture.

"We've demonstrated the feasibility, we want to improve the process efficiency," explained Willauer.

Collum is just as excited.

"For us in the military, in the Navy, we have some pretty unusual and different kinds of challenges," he said.

"We don't necessarily go to a gas station to get our fuel, our gas station comes to us in terms of an oiler, a replenishment ship.

"Developing a game-changing technology like this, seawater to fuel, really is something that reinvents a lot of the way we can do business when you think about logistics, readiness."

A crucial benefit, says Collum, is that the fuel can be used in the same engines already fitted in ships and aircraft.

"If you don't want to re-engineer every ship, every type of engine, every aircraft, that's why we need what we call drop-in replacement fuels that look, smell and essentially are the same as any kind of petroleum-based fuels."

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.

Crazy to think that it can run in existing engines already in place and even fuel Jets as well. Being that it's converted from the ocean, I wonder if it would even qualify as being carbon neutral? 'merica!!

:thumb:
 
This. Is. NUTS!!! if they could figure out how to make it work fully with no issues this could literally save our planet. also if it only produced water as a biproduct then that would be great as well.
 
Awesome !!
Though I'm not gonna take the time to read the whole article, I'll just go put seawater in my gas tank!
Should work just fine right? :thumb:

Being that the goal was to essentially make gasoline out of seawater, the byproduct would still be CO2. I'm not 100% sure on this but, being that it's made from seawater, it may qualify as being carbon neutral.
 
Saw this article yesterday. Clearly there is more going on in this process than is described because I can't for the life of me figure out how they are extracting CO2 from H2O without some other inputs. Would also be interesting to know the energy input/output of the process.

Either way, its damn cool and potentially gamechanging if the process can be scaled.

Of course, now we'll have to worry about the environmentalists screaming about us running out of seawater.
 
^^ that's what I've been scratching my head about.. H2O and NaCl (salt) where's the C carbon for CO2? (Yes I know there's other elements there like potassium, magnesium, sulfur, but just don't see a big Carbon source). Guess that's why I'm not a Navy Scientist! Lol
 
Very cool. I wonder what the ratio is of gallons of seawater necessary to make one gallon of finished useable fuel. In any event, the only way we will ever neuter the middle east is to make oil obsolete. Maybe this is finally a step in that direction.

The CO2 is dissolved in the seawater or can be derived from other dissolved carbon sources. Atmospheric CO2 dissolves in surface seawater. The useable carbon is present at dissolved CO2, carbonate CO3, and also as bicarbonate HCO3.

There are several ways to convert all that into CO2 which can be extracted from the remaining sea water

The ocean is basically a giant buffer of dissolved carbon. This is what allows sea creatures to make their shells (carbonate) and for reefs to form (carbonate). All the creature needs to do is find Calcium from somewhere. Also limestone is another source or carbon... in the form of carbonate as well.

GEEK!! :crazyeyes: :cheesy: :thumb:

I wonder how much energy it takes to facilitate the process? One thing is for sure is that they are not creating "new" energy.

I agree that the technology is cool, but it generally seems the solution for one problem creates another.

True!!!

I am a chemist... what can I say.

I also had to write a paper on something related to this in grad school. The idea was we could fertilize the algae in the ocean because they consume CO2 and turn it into solid carbon, end goal being to sequester the co2 as solid carbonate at the bottom of the ocean. Hahaham. That way we dont all have to drive hybrids haha.
