I just finished watching “Modern Marvels” on the History channel, where they did a special on truck stops and truckers. They finished the show talking about biodiesel and Willy Nelson. “Great,” I thought, “some good press about biodiesel in the media”. Except, once again as happens way too many times, the reporter equates straight vegetable oil with biodiesel.
To the layman, I can see why it’s easy to confuse. Rudolf Diesel first invented his engine to run on Peanut oil, as the reporter accurately claimed. However, for a reporter, who is suppose to research things before he reports them, even an extra 10 minutes using Google or Wikipedia in his investigation would have told him that the modern engine looks almost nothing like Rudolf Diesel’s engine, and that while it’s true that they can run straight vegetable oil, almost none do because it’s harmful for the engine.
The other thing he would have found, as posted other places on this blog and our corporate website, is that straight vegetable oil (SVO) and Biodiesel are not the same thing.
I’ll say it once more in more simple format: “Vegetable Oil Is Not Biodiesel“.
So, what do biodiesel and straight vegetable oil have in common? Biodiesel is usually made from vegetable oil. But, in truth, biodiesel can be made from animal fats too, or people fat, for that matter. Through a process called transesterification, vegetable oil is stripped and converted into Biodiesel (which is technically called a mono-alkyl ester). This new chemical, trade named “Biodiesel”, is now more chemically similar to petroleum diesel, and has many of the same characteristics of it’s petroleum cousin. It is even accepted by the EPA as an approved fuel and fuel addative, and has an ASTM standard (D-6751). Vegetable Oil doesn’t have any of that.
See, Vegetable Oil is food, Biodiesel is fuel.
So, get it right next time, Mr. Reporter. I bet I’ve heard this mistake five or six times in the media over the last two years. You’re not helping our industry by adding to the confusion that the average consumer already has about biofuels.
