Breakthrough in Biodiesel Production

MGR writes "National Geographic is reporting that Japanese scientists have discovered a way to convert vegetable oil into biodiesel with a much less expensive catalyst (between 10 and 50 times cheaper) than what is currently used. From the article: 'Any vegetable oil can become fuel, but not until its fatty acids are converted to chemical compounds known as esters. Currently the acids used to convert the fatty acids are prohibitively expensive. Michikazu Hara, of the Tokyo Institute of Technology in Yokohama, Japan, and his colleagues have used common, inexpensive sugars to form a recyclable solid acid that does the job on the cheap.'"

  1. Biodiesel more at the pump? by Darlantan · · Score: 5, Interesting

    Err, this seems backwards to me. Everytime I've seen bio available, it's been below standard diesel prices. Perhaps it's just a regional thing where I'm at, but I've been under the impression that the real problem with biodiesel was A) older fuel lines may be degraded more quickly by biodiesel, and B) producing enough to fuel the world's fuel needs was a big issue.

    Of course, I'm no biodiesel guru, but it is of some interest to me -- I drive an older diesel (which I plan on converting to run on SVO, as soon as I get the facilities to make this feasible.)

  2. Cheap Fuel by Thunderstruck · · Score: 3, Interesting

    I was unable to tell from TFA, though I did not read it closely, whether this will make soy biodiesel as cheap or cheaper than standard diesel is now.

    Not that it matters, I just bought a nice, fuel efficient gasoline powered car... It should be wearing out about the time the patent expires on this new process.

    It isn't going to solve the world's dependence on oil overnight, but it's perhaps a step forward.

    The next problem will be a shortage of arable land due to land used to produce the vegetables that are then going to become diesel. This could solve one problem and lead straight into another

  4. That's not the problem. by Jaywalk · · Score: 4, Interesting
    The problem with biodiesel isn't that it's too expensive to produce. The problem is that there simply isn't enough oil to replace significant amounts of fossil fuel. And there is the issue of what happens to the price of food oil if too much vegetable oil is converted to fuel usage. According to this study by the University of New Hampshire, it is possible to make the necessary oil using oily varieties of algae which can be produced on non-arable land.

    Making soybean biodiesel cheaper won't solve the problem because the limited supply will only meet so much of the required energy needs. It might even cause more problems by creating economic pressure to convert food oils into fuels.

    Since this is an accomplishment not by American Industry and is contrary to the current powerbrokers of Dino-fuels it won't mean shit in America.

    2005: law is passed giving a tax credit for bio-diesel mixes. But this eliminates all B-100 biodesiel because it's not a mix. Tax rebates are not made available to the consumer.

    2006: law goes into effect which raises the bar on small diesel engine emissions (commercial vehicles excluded) making it impossible to sell a new diesel car in the United States because the fuel used in the Unites States is too dirty to pass the emissions test. It is not the engine, it is the fuel that fails the test. There are no American automotive manufacturers selling a diesel engine in the United States.

    2007: law is supposed to go into effect to introduce low sulphur dino-diesel which should permit diesel sales to go into effect. I'm a little suspicious that this law isn't currently under assault. But we won't know for another year.

    Go search the internet. The technology for production of bio-diesel and the studies identifying the environmental benefits have been in publication, on the internet of all places, since 1998. And what has been done about it?

    1000 w/m^2 is still 4047 kw/acre - even at 1% efficiency on 2 dozen acres you're talking a megawatt per car!

    With some additional data:

    20 horsepower (average use) * 746 watts/hp = 14920 watts for a car to run all the time - so say an average of 1500 if it's used 10% of the time

    Even at 1% solar to fuel efficiency and 33% car efficiency, that's 450 kw or 450 m^2 per car

    an acre is about 4047 meters => 9 cars/acre

    A different way (I know it's only Wikipedia, but if these numbers are right...):

    Algae: 10,000 to 20,000 US gal/acre

    Let's see: I use about 15 gal/week * 52 weeks = 780 gal/year - let's make it 1000 - so I'd need up to 1/10 of an acre.

    Since it takes about an acre of farmland to feed a person, this seems quite reasonable. Even better, algae can be grown in the desert using seawater, so land and water that is useless for most other purposes can be used for biodiesel.

    Not really. The Saudis are more aware than most that their oil domination is rapidly going to run out. They even have a saying on the matter. "My father rode a camel. I ride a car. My son flies a jet. His son will ride a camel."

    No, what I would expect more than anything is the Saudis to invest heavily in BioD and other alternative energies once they see a winner and corner that market as it emerges.

  8. necessity of exporting? maybe not... by zogger · · Score: 5, Interesting

    The development of other fuels will not negate the usefullness or use of traditional petroleum. Nations that are oil rich will continue to use the fuel,especially if it is their primary natural resource, even if their export market diminishes. And especially then, with no imported cash from exported oil, they would be literally forced to directly use the oil themselves to the best of their ability. And it is quite possible that as the islamic world (if we want to limit the discussion to there) matures (most are under the age of 30 right now), they will want their own manufacturing and other islamo-centrist based business, rather than purchasing products from other areas. Necessity *and* desire at that point. You have to remember, petroleum is not only a transporation medium, it is also critical -today at least- for manufacturing.

    With that said, I heartily welcome more R and D and deployment of biofuels. But older fuels are still used, I am using "stored solar"-wood-as my primary residential heating source, same as humans have been doing for millenia. We have a "domestic supply" and it is quite significant enough for our needs, hence no need to "export cash" to purchase someone elses developed energy product, nor do we need to "export the raw materials" for anyone else to use. That's a micro scale, macro between nations is just "larger".

    Humans will use up the available petroleum, biofuels becoming massively more available or not. The use will only drop when it gets closer to a stasis point, when it takes one "barrel of energy" to produce an identical barrel of energy. Then it will stop.
