Utilizing Bio-fuel Beyond Experimental Use

grumpyman writes "A C$14 million factory near Montreal started producing biodiesel fuel two weeks ago from the bones, innards and other parts of farm animals. At full capacity plant will produce 35 million liters (9.2 million U.S. gallons) of biodiesel a year, the greenhouse gas equivalent of removing 16,000 light trucks or 22,000 cars from the roads."

    For some time I've thought the future of automotive fuel lies in biodiesel rather than hydrogen. Hydrogen is just very hard to work with because of its low energy density and the fact it is normally a gas. Generation, transportation, storage and utilization all face large challenges.
    For biodiesel, all the steps except generation are already solved and the infrastructure in place, and the generation problems do not seem large. (Even without the existing infrastructure, I suspect biodiesel wins economically.)

    Generation from algae is particularly promising, as it doesn't require arable land, and can use salt water.

      I call bullshit on at least one claim. The primary greenhouse gas is CO2 and biodiesel is still carbon based so it still produces CO2. If that claim is wrong, what about the others?

      Alright, genius, what do you think is going to happen to the carbon in the waste products used here if it isn't used to make fuel?

      A damn lot (all?) of it is going to end up back in the environment anyway as it decomposes. That's why this is "carbon neutral."

      It may be true that biodiesel reduces our consumption of fossil fuels, but that depends on how much fossil fuel is consumed to produce biodiesel.

      If more usable energy comes out of that process than went in, the increase in CO2 in the environment has been reduced.

      Biodiesel emits CO2, this is true.

      However, that CO2 was trapped by plants in the last year or two. Any large extent to which we switch to biodiesel will dramatically reduce net CO2 emissions.

      Petroleum based diesel emits CO2 that was trapped by plants tens of thousands of years ago (or more). This causes a shift in greenhouse gases. By and large, B100 biodiesel does not.

      The real problem, however, is cost. Yellow grease produced biodiesel has a wholesale cost 2-3 times greater than petroleum based diesel, and plant-based biodiesel costs 3-4 times more wholesale. Unless there is a tax or government subsidy for recyclable diesel (diesel in which the CO2 was trapped by plants recently), biodiesel will never take off b/c few consumers will double or triple their fuel costs to use a sustainable energy source.

    Premptively, let me make this very clear so we don't need to have the same discussion everytime biodiesel comes up.

    First, biodiesel has a positive energy balance, to the tune of about 3.2 units out for every unit you put in. http://www.nrel.gov/docs/legosti/fy98/24089.pdf

    Second, biodiesel is 78% carbon neutral with regard to greenhouse gas emissions (see previous pdf). That is because the majority of the carbon emitted when you burn a gallon of biodiesel was captured from the atmosphere when you grew the plant to make the vegetable oil. However, the methanol used to make the biodiesel (fatty acid methyl ester) is made from natural gas, at least in the US. You could make 100% renewable ethyl ester biodiesel from ethanol, or make methanol from landfill recovery biogas, but we don't currently.

    Third, soy and corn oil are crummy crops to make biodiesel from. But that's where the lobbying money is right now. Other plants have much higher yields.
    http://journeytoforever.org/biodiesel_yield.html

    Forth, no, it isn't a question of "food or fuel"? We can do both! Whenever you hear that argument ask yourself whether the person is well meaning but misinformed, or as been happening recently, is part of astroturf campaign to preserve the status quo of the petroleum economy.

    I've posted this before, but I've been using straight waste veg oil in diesel cars for years. Some older diesels don't need any modifications - the PSA diesels found in Volvos and pretty much any French car (Peugeot, Renault, Citroën) run quite happily. You *do* need to find one that has a Bosch-type pump, otherwise you'll get about 1000 miles out of it before the pump seals break up. If it's very cold (over here in Scotland very cold is below 4C for more than a few days) you can chuck a gallon of unleaded in on top to thin it out a little.


    I found that in my Citroën CX 25DTR T2 (2.5 litre turbodiesel) I had quieter, smoother running, less exhaust emissions and a small increase in power. I could increase the boost (and thus excess fuelling) quite a bit without hitting the smoke point or cooking the turbo. All this from (effectively) free fuel.

    I have seen them. I don't see what you describe.

    I live in Denton, TX. The City has it's own Biodiesil Plant, one of the first. All the city vehicles run on B20; all the city trucks, heavy equipment, garbage trucks, etc...

    Even though, its not 100% biodiesil (B20 is 80% diesel 20% biodesieal) they use a remarkable amount of it. There are a few more public biodiesel pumps in DFW area, and I think one other city around here uses it for thier equipment.

    Ours plant is out by the land fill, and basicly all the vegetable oils, from restaruants and farms etc.., get processed. Pretty cool, and not experimental at all.

    Unless there is a tax or government subsidy for recyclable diesel (diesel in which the CO2 was trapped by plants recently)

    Motor vehicle fuels are already taxed. Drastically cutting taxes on biofuels compared to petrofuels can subsidize them without "subsidizing" them, although European countries generally have more room to cut taxes than North American countries do.

    few consumers will double or triple their fuel costs to use a sustainable energy source.

    Unless worldwide crude oil extraction peaks and the supply curve moves so as to double or triple petrodiesel prices anyway. Then biodiesel will become even more attractive.
