Converting sea water to Navy jet fuel

Navy scientists and researchers say they are close to a breakthrough toward turning seawater into jet fuel.

The U.S. Naval Research Laboratory is working to extract the carbon dioxide and produce hydrogen gas from the seawater. The key is then converting the carbon dioxide and hydrogen into hydrocarbons that can then be used to develop JP-5 fuel stock.

JP-5 is what fuels Navy jet fighters and results in multiple fuel transfers to aircraft carriers to maintain their onboard fuel stock. Producing that fuel from the abundant sea water would save the Navy from executing those sometimes risky transfers.

“The potential payoff is the ability to produce JP-5 fuel stock at sea reducing the logistics tail on fuel delivery with no environmental burden and increasing the Navy’s energy security and independence,” said Heather Willauer, a research chemist with NRL.

Navy officials estimate the process used to convert the seawater to fuel would cost the Navy between $3 and $6 per gallon.

Of course, this supposed breakthrough comes as the Republicans in Congress have fought against the efforts by the Navy to develop alternative fuels. Republicans claim the Navy can’t afford to attempt to create fuel out of seawater or cooking oil when the defense budget is getting slashed.

Navy and Marine Corps leaders have said they can’t afford not to considering the advances the Marine Corps has made in operational energy in Afghanistan.

    That would be awesome to have as a fuel source. That would have extreme tactical value as well. No underway replenishment for JP-5 creates much greater independence for our sea forces and the underway reps could then be used entirely for the purpose of transporting food and commodities. I usually vote red, but I think anyone who is against the Navy finding such technology must have some heavy stock in the oil industry and has their values misplaced. I love that picture too. Such a beautiful, well-designed machine.

      OK, I’m a lefty, semi-tree hugger. I walk and bike much more than I drive. But let me run this stat past you. The US has a horrible electric distribution grid and efficiency standards. If the US had the same standards as Europe does for his its home appliances and equal quality grid, we would not need to import a single ounce of oil. Its a national security issue, period. Getting off fossil fuels whenever possible, rebuilding the electric grid and increasing efficiency is the best long term thing we can do for the health of the nation.


      the reason republicans are hesitant when it comes to the research and development in the navy and elsewhere in the arms services is because the democrats are cutting funding to the military as a whole. when funding is cut then so is R&D. its not that the big bad republicans want the navy to continue using fossil fuels for their personal gain as much as it is a consequence to losing funding for this type of stuff across the board. if the money that would be used to develop sea water based JP-5 could be used in something more critical, like oh you know, ships, jets, personnel, ammunition, security ect. then why not put the money there? this is experimental and a long way from perfection to make it worth while. in a time of defense cuts we cannot afford to put money into an imperfect product. This is what the republicans are saying. they are trying to protect the remaining, limited funds the navy has left. keep voting Red, it may be the last hope for our military as we know it!

    • Richard Bunn

      The conservatives in Congress were upset at the $Kilo per gallon cost of biofuels for the tests the Navy did to varify that you could run a ship or fly an aircraft with the stuff. Congress is not populated by technically savy folks and when they see a program taht is spending 10 to 20 times the going rate of fuel for a biofuel project they believe it may be a waste of capital. Further, it would be in INDUSTRIES interest to develop biofuels or sea-water to fuel systems on the open market and sell it to us. Let industry take the risks and reap the rewards.

      • Jimbo

        Uh, it wasn’t the “conservatives” in Con-gress, it was their constituents that threw a fit over the price. We don’t want to pay exorbitant prices for faddish fuels.

    • Pat

      Do you know how much energy it takes to split hydrogen from water? It’s not easy or cost effective at all. If it was we’d all have hydrogen powered cars.

    • blight_

      If only we could go back to a nuclear navy…

    • FSalazar1962

      Yes, it is awesome, until Big Oil Lobbies Congress to put the technology under wrap and Congress does it.

  • Bob

    Does anyone understand what a game changer that would be, if true?

    If you can make a hydrocarbon-based fuel from seawater than the carrier in essence becomes an tanker for every ship in the battle group that uses a hydrocarbon based fuel for its engines. Like a Aegis cruiser which has jet turbines. Its just a jet fighter engine strapped to a chassis turning shaft to a gearbox.

    The question is the energy in equation. Does it require the reactor on the carrier to provide enough juice to operate the synthesizing machinery.

    Interesting on many fronts.

  • DougieR

    That’s great for the Navy…but screw them why can’t we have this too! As with so many other technologies passed from the military to the civilian world such a technology could have world changing effects if it could be made cheaply and distributed widely enough.

    I for one welcome our new low-sulfur diesel economy…an end to reliance on OPEC and a Passat TDI in every driveway!

  • IknowIT

    Yes- the amount of energy consumed will be the major issue and question. Doing things like this is usually total energy negative, at least so far. Also, I wonder how much space the distillation plant would take.

    On the other hand, if this is not energy negative, not sure why this wouldn’t have commercial implications outside of the military? Is this technology protected, and can the military lease it out?

  • DGR

    Kinda suprised at the cost, thats not all that big of a savings. Still valuable from a standpoint of not having to stockpile fuel and reducing logistical requirments, but if the estimate is $6 you can rest assured actual cost will be closer to $8-$10 a gallon.

  • Noha307

    Imagine what this could do from a damage control perspective as well.

    Enemy Ship Captain: Direct hit! Our missile has struck their aviation fuel supply! … What?! No explosion?!

    Enemy Lieutenant: Sir. It seems our missile impacted a compartment filled with seawater.

    ESC: I could’a sworn that’s where they’re fuel supply was. Hmmm…


  • Lance

    I dont trust this since sea water has too much junk and sea life to make it convert on the ship. I dont see it mostly environmental wish thinking.

  • Musson

    Seawater contains up to 200 times the amount of Carbon Dioxide as air. So, that is why this could actually work.

    And, if we build a network of Molten Salt Liquid Thorium reactors (a walk away safe design) we could create liquid hydrocarbon fuel around the seawater on any coast in the World.

  • Jeff

    Maybe they gt it “working”. But how much do they have to take in to get a usable quantity out? Is it 1 gallon in 1 gallon out or 1000 gallons in for 1 gallon out? Will we be creating new waerfront property by reducing sea levels? Maye they can tout it as a way to combat he rising sea level due to global warming :)

  • GET051

    Now if the Navy invests in fishing rods the Carrier Group will never have to come home!

  • Tad

    Perhaps even better is getting the hydrogen in the first place. That could be used in fuel cells to power the ships.

    Something tells me the devil’s in the details and this just won’t pan out, though, either as hydrogen for fuel cells or for JP-5 production. We’ll see.

  • Rip

    Show me the math guesstimate…how much volume per day @ how much energy in? Gallons seawater = barrels of JP-5? What would be the physical size of the machinery
    space to achieve a economic output? Gee, the mature plant will only take up 1/5th of the space available in a modern carrier.

    This will probably appear on a Popular Science cover soon….and be realized maybe in 2035, if ever.

    This is a typical, if wishes were horses, we all would ride, journalism story. There should be an annual award (like the Darwin) for the best tale of such ilk.

  • DShirley

    Hmmm….just like any other natural resource on this planet, sea water is “limited”…some may not think so in the short term, but the reality is….IT IS. We can convert sea water for drinking water, but in this instace how soon(if realized) before society becomes “wasteful”?? As indicated above, how much sea water would be consumed to get the energy required??? The sooner we get to renewable energy, the better. Let’s stop looking at ways to trash the environment, we should already be in a transition phase…let’s start pushing out more R&D $$$ to get there!!

  • Benjamin

    What chemicals would the ship need to carry to break down the water into hydrocarbons and make it into JP-5?

    Getting this done will drastically cut the costs of fuel for the Navy.

  • scooter

    Republicans are not deep thinkers and just live for the day and are selfish. Its like when you play chess certain people can only see one move ahead while some can see 5 to 6 moves ahead and already know what you would do in certain situation. Its sad to see that they let there primitive instinct for greed consume them. What is this world coming to.

  • Northener

    Okey this is only my estimate a educated ques in it’s best.Considering the fact that this ships has to distill it’s fuel on sight that would mean 3-4pieces at least 15 long distillation columns. (meaning easy to destroy target containing hydrocarbons).

    Cerium okside based reactor with FT process chambers can be fitted in couple of cargo containers easily. Electrolysis can can be done in space of your average car battery.That CO2 harvesting is still prototype phase but estimate is several cubic meters in second. However it can be stored so Co2 capture ratio can be reduced and produced in slower scale and taken use when needed.

    Economical = not in my life time
    Doable = depends about speed of development co2 separation from seawater
    Wise = Well let’s leave folks with uniform to decide.

      Fortunately we have a handful of posters that have knowledge of hard science (I’m a physics major).

      It’s humorous to see the bipolar nature of posts.
      One one hand you have people who believe in anything green.
      On the other we have people who understand the laws of thermodynamics.

      Sadly, both sides votes count equally.

    • SJE

      CO2 harvesting can be done through reduced pressure/ raised temperature, such as harvesting from the cooling stream out of the turbines. Alternatively, the USN could carry carbon, e.g. coal.

      A better source would be destructive carbonation of waste products generated on board, although you also have to deal with variable input streams and contaminants. Think of it: our jets run on sailor’s sh**t

      • Northener

        Well if you would know about FT process and how it works major cost is gas purification and that is if I correctly remember last budget meeting it was 2/3 of plants overall cost.

        And on more things that would require tons of hazardous chemicals to be stored on board. the beauty of this current system that as long as reactors keep producing power we would have hi-purity materials (altough in small quantities)

        • SJE

          Are you looking at the economics for FT process based on natural gas? Costs differ depending on feedstock. For gasified waste streams there is certainly a problem of variability and contaminants.. The question is the increased purification costs and complexity versus availability of feedstock. e.g., you can use thermal decomposition for direct production of CO and H2.

        • str8testshot

          Could it be possible to harvest the CO2 from gas turbine exhaust in the surface fleet? of course we would have to avoid over pressure of the exhaust but would see additional benefit from cooling it. if we are talking next generation why not power Jet turbines on hydrogen alone; by pushing forward the fuel cell issue.
          I’m no Chemist nor physicist just a Turbine Guy

    • joe from tampa

      you don’t know much apparently, because this is economical now; because it’s a nuclear reactor with nothing better to do anyway, it’s doable now because we can already purify seawater into hydrogen and oxygen at a rapid pace and our nuclear submarines do that every hour of every day, and it’s wise because it gives our ‘folks in uniform’ the flexibility to do ther jobs effectively.

    • Chris

      Did you see the pictures of the machinery they have already built? Looks to be pretty compact. The spec paper also claims only a small amount of electricity is required.

  • Andrew

    I imagine its doable, because they’ve got a nuclear reactor on-board. So even if its energy-negative, its not a problem as long as those fuel rods are working.

  • Jerry

    Game changer for the entire global economy, not just the Navy, if this can be done in a cost-effective manner. If you can make JP-5 out of seawater, surely you can make the military’s universal fuel–JP-8–out of seawater, too. For that matter, if it’s cheap enough, there’d be a huge incentive to convert all manner of civilian internal combustion engines to burn JP fuel, too.

  • Pit Snipe

    There is something most all of you are forgetting about the concept of utilizing sea water for fuel. One of the byproducts from production is pure H2O (either from production or as exhaust vapor). This is a good thing. A large portion of a Navy ship’s machinery rooms are utilized for producing potable water for the crew, steam for cooking in the galley’s and creating electricity for the ship’s functions. These systems already convert sea water for these uses and countless others. This concept could not only produce fuel for aircraft, the Marine’s landing craft, and for utilization of the ships themselves, but could improve the efficiencies of the already existing purification plants while utilizing many of the otherwise wasted byproducts.

    Hydrogen is the most abundant element known to man, its biggest problem is stability when it is not combined with another element (so throw the fuel cell idea out the window, to volatile for a war ship to store). But breaking down the hydrogen molecules out of sea water would be extremely effective because you would not have to add a catalyst to the mix, at the sodium in the salt water serves the same purpose. The incorporation of the proper amount of carbon molecules will be the tricky part that I am sure our government figured out how to do a long time ago. Make hydrogen from water? That’s so simple that is is taught in high school chemistry (sometimes as early as Jr. High). The biggest hold up is foreign oil. This concept could serve more of a purpose than just fueling our military fleet, it could also obliterate our dependance on foreign oil while supplementing the Defense Budget… Navy makes fuel for civilians. Navy sells fuel to civilians in USA only. Navy creates residual income of monumental proportions. Our defense budget is better off… less money out, more money in, win-win, you see?

    • DShirley

      Good laydown, but if this tech was developed on a global scale to revolutionize life for 6 plus billion people…..what is the demand on sea water????

    • Frnak

      I love it way to see it that way :)

  • indianmedicine

    It is only impractical if you are a Democrat, otherwise you would see it being pushed through. PIT SNIPE. thanks for the Explanation for us Non-Chemistry Types – makes sense & understandable.

  • dave

    Seems like this is just a story to slam Republicans. If this technology exists it won’t be the Navy, it will be civilian scientists finding the way to convert seawater.

  • votes blue and red

    Let’s be honest, both political parties are beholden to corporations that put their financial interests ahead of the security of the USA. When the power brokers who throw money at both parties have little personal investment in the services – how many bankers and Wall Street money men (and women) have combat tours on their personal resumes? – should we be surprised at their willingness to turn defense decisions into another stick with which to beat their political opponents. When business or political mythology clashes with science, engineering and technology, why is mythology champeoned? Because mythology drives emotional responses that are much more politically useful than analysis and rational thinking. It’s all fine and dandy to argue that we can just build wind mills, or that there is no global warming, but the scientifically evident truth is that we have a high energy economy that is reshaping the climate in ways that threaten our long-term security. If your mythology is threatened by alternatives to oil pumped out of the ground, you vote against development of technologies that are beneficial to both civilian and defense applications.

  • Civilian nuclear powerstations don’t respond well to peaks and troughs in demand. Might this technology allow a powerstation to switch its electricity output to a neighbouring fuel plant at times of low customer demand?

    It may not be cost-effective to set up commercial nuclear-powered sea-water refineries around a nation’s coasts, as has been suggested; but countries which produce a high proportion of their electricity from nuclear energy, such as France, could potentially use their network’s over-capacity at times of lower demand to power similar fuel plants.

  • Dfens

    There is no better way to fund terrorism than buying oil. It financed the war against us in Iraq and Afghanistan, and paid for the “Arab Spring” as well. Too bad oil dependence has become a political football. It is really an issue of patriotism.

  • PolicyWonk

    Wow – the republicans are openly standing in the way of our nations energy independence while openly claiming to support the military?

    It ironic that the Joint Chiefs of Staff and DoD consider energy independence to be a matter of national security – only to be opposed by the party that for decades tried to convince people of their superiority of leadership during wartime, etc (I suppose the botched Iraqi and Afghan campaigns put that to rest).

    I guess that article in last month’s issue of Forbes was right: the democrats are now the party to look to for leadership in matters of national security and defense.

    My, but how the world has changed.

  • mindmedic

    Gee! check out this article……. Several farmers and some agricultural companies have been developing hydrogen producing technology for the last several years. Remember (you old guys) the stories about someone developing a carb. that turned water into fuel. Well guesse what? Maybe those stories were or will become true. The theory is simple, run an electric current through water (with or without salt) and you split the H2O into its component atoms (oxygen and hydrogen.) It gets more complicated after that but it can and is being done. This is not new technology.

  • Roland

    This are old inventions. Some country already invented it. Country like the Philippines invented a water powered engine. Check :

  • MindMedic

    second comment….

    Why are they trying to create hydrocarbon fuel when pure hydrogen is not only a great fuel but is environmentally much cleaner (primary waste product is water.) My understanding is that the main issue remains compression for storage. There has also been some work around the use of Hydrogen Peroxide. Go do some reading about Germanies liquid fuel research in the 30’s and 40’s. H2O2 is a viable alternative but does have its environmental issues…

  • James T. Kirk

    Bah, enough with this Buck Rogers stuff! I’m sticking with my trusty dilithium crystals!

  • Curt

    Gee, how many ways to distort the truth in one article.
    1. It potentially supplements JP-5 supplies on the CVN. There is no where near enough power on the carrier to totally replace JP-5 from other sources. Read the quote.
    2. Although this iis alternate energy, it is not even slightly related to biofuel purchases (the topic of the linked article)! Being opposed to spending $24 gallon buying BIOfuels and basic research into liquid fuel from nuclear power that only makes sense in a naval application is completely different! Why should DoD be the lead for Biofuel purchases? Although it is the largest government user of fuel, it is a miniscule fraction of the market..
    3. This is converting nuclear power (no Bio here) to liquid fuel and more importantly it is basic research. And the $3-$6 per gallon? That assumes that the electricity (the most expensive part of the process by far) is free! The economics only makes sense for the Navy, and only on Carriers. That kind of research is why we have NRL.

  • L Berry

    What hogwash…Scientists have for years tried to find an economical way to produce Hydrogen. A lot of effort has been expended towards the end goal of clean and abundent fuel sources. The hydrogen engine to propel aircraft has been a dream product. But after billions, if not trillions in research, all of a sudden the navy has found the solution. They will extract teh nitrogen in sea water. Yes, we have oil leaks all under the sea, but the percentage of oil to water is so low it is mind boggling to think of how many millions of gallons would be required to extract just a gallon of JP-5.
    But the navy has been buying biofuel at $7-10 gallon so they aren’t dependent upon foreign oil. PS, JP5 was $3.50 at the same time.
    I guess common sense is one thing the Navy can’t buy.

    • Curt

      you obviously didn’t get the part about how you extract CO2 from seawater with a catalyst and electricity, then combine it with H2 from electrolysis (more electricity), a catalyst, and a bunch more electricity to form short chain hydrocarbons, then with still another catalyst and still more electricity, you form the short chain hydrocarbons into long chain hydrocarbons to make, for lack of a better term, synthetic kerosene. Blend in 2pct or so additives and voila, JP-5. Hydrocarbons from seawater!

  • Kevin

    Nothing like politicians putting the good of the defense of the Realm first. I mean, they wouldn’t be concerned about any loss of income to the oil compmanies ahead of an enormous advantage to the Navy would they! No politician would ever bow to big business and against the well being of the country!

  • Roland

    The country”s criteria for clean energy should be cost free, cost effective and environmentally friendly. These criteria for clean energy will help boost the country’s energy requirements and economy. It will substitute foreign oil dependency, create jobs, boost country’s security and help the economy.

  • Michael J. Keenan

    The entire process is energy negative, i.e., it will take more energy to make the fuel than we will get from the fuel. The main reason seems to be to avoid hazardous conditions during ship-to-ship fuel replacement. We have been doing this with carriers for 80 years without major incidents. There is no safety rationale for
    continuing this project that justifies the projected costs.
    This is interesting chemistry, but economically unsound.

  • conrad

    Anyone who thinks we can get enough ,affordable, JP5 from sea water to fuel the jets is someone I have a gold brick to sell. this is pure “Junk Science”!

  • RogCol

    Anyone that has served aboard a Nuclear submarine, knows that we have been turning sea water into hydrogen and oxygen for decades. if you have the excess power to do so, First you do not use sea water, you distill it into pure water. dumping the excess brine over board and using the pure water for a variety of purposes. Part of this pure water forms the acceptable form of water for the splitting process. The oxygen is kept on board and the hydrogen, due to its explosive nature is pumped overboard. Not to mean that oxygen is not dangerous in it’s own right. Check on the USS Sargo. If we can develop engines that can run on CNG, this should be a possibility, given the power to produce it.

    I would also suggest that harvesting biomass from the sea and converting it to carbon might be easier and cheaper than trying to extract a few hundred PPM from the atmosphere.

    If I remember my old schooling, water is a finite resource. It is cycled through the evaporation to rain process. If we convert significant amounts of sea water to other elements, we will untimately reduce the amount of water circulating through the earth’s ground and atmosphere. We can’t drink jet fuel! Carried to an extreme, our fleet would become small islands. The oceans seem endless, but they are not.

    well if an enemy submarine hit the tube leading to the water and they didn’t have any other fuel then they would run out of fuel and we would lose.

    I don’t see how you can make a fuel from salt water, considering the composition of it..

    O (oxygen) = 85.84%
    H (hydrogen)= 10.82%
    CL (chloride) = 1.94%
    Na (sodium) = 1.08%
    Mg (magnesium) = 0.1292%
    S (sulfer) = 0.091%
    Ca (calcium) = 0.04%
    K (potassium) = 0.04%
    Br (bromine) = 0.0067%
    C (carbon) = 0.0028%

  • When the writer of this article conflates the subject of the article and “fuel from cooking oil” it tells me all I need to know about his intelligence. They are two completely different subjects. One involves keeping warships at sea longer without resupply – a good thing leading to tactical advantages – while the other involves pie-in-the-sky greenie nonsense. Blaming Republicans for having common sense by resisting efforts to run military equipment on french fries shows how desperate the writer is to insinuate his political bias into his stories. As someone already pointed out, nobody is claiming that jet fuel from seawater will save money. It will cost more energy to produce the stuff than will be realized in the resulting fuel… but luckily aircraft carriers have a handy nuclear reactor on board. This isn’t “green” technology, dude.


    When I was in the navy on a destroyer we refueled a gun boat which was 150 feet with one 3 inch gun. I finished my “A” school in avionics and saw many jets refueled by GRAPES.
    I read about this development and it is ENGLISH. Sodium hydroxide and carbondioxide or monooxide is mixed to produce the fuel. During a 3 month period 20 gallons were produced. The next phase is to produce more fuel in a shorter time.
    The oil companies do not like this since who would need oil? Therefore by definition the right wing will not like a cheap fuel that makes everyone HAPPY. This would also level out an energy demand and the whole world would be HAPPY and the right wing would be so MAD with less sadness and hate in the world.

    Since this is a technical blog, I am surprised to see no real technical analysis of this idea. Assuming unlimited energy from a reactor, there is no doubt some way to use some of that energy to synthesize hydrocarbon fuel out of something. But this type of process always loses energy and has no particular commercial value unless all the recoverable geologic oil is gone – which is hardly the case. It could potentially save the Navy from schlepping oil around but I doubt if the reactors in a single carrier really have that much to spare. Sounds like a boondoggle to me.
