This must rank among the most exciting weeks as far as energy-related news worthy items are concerned in the popular and academic press. I just got done writing about the potential health concerns with widespread use of ethanol E-85, when I read this news report on a Honda diesel car that could be introduced in the US by 2010. This car can get an unbelievable 62.8 miles per gallon on US highways. That is certifieably better than most hybrids, even a Prius. This is fascinating and only proves what I have been saying for a while. Diesel has tremendous potential, especially now that technologies for making diesel as clean as, or cleaner than, gasoline cars are becoming real and commercially viable.
According to the article in CNet news:
Honda expects to bring the clean-diesel car to the U.S. by 2010. It gets 62.8 miles a gallon on the highway, but otherwise looks and feels like a regular Accord. At that mileage level, the car is about as “clean” as a new Toyota Prius. But if you run it on biodiesel, a form of diesel made from vegetable oil or animal fat, it would be even cleaner than a Prius (Priuses get 60 in the city).
The advantage of diesel cars, however, is that they pack a lot of power.
The car was shown off with a number of other cars in Sacramento, Calif., earlier this month as a way to promote clean diesel cars and technology. In the ’90s, California passed strict emission controls that restricted the amount of sulfur a car could emit. As a result, diesel manufacturers curbed sales to California and the U.S. in general.
Since then, petroleum manufacturers have devised cleaner diesels that only emit about 15 parts per million of diesel, down from hundreds of parts per million. That satisfies the California law. Manufacturers, meanwhile, have come out with more efficient and powerful diesel engines that get 20 to 40 percent better mileage than their older cars.
“A lot of changes have taken place in the engine, all thanks to electronics,” said Allen Schaeffer, executive director of the Diesel Technology Forum, which helped organize the Clean Diesel Technology Tour. (Cars from Audi and a tractor trailer rig from Caterpillar were also shown). “Half the cars in Europe are diesel.”
Thus, diesels, usually thought of as smelly, are now environmentally somewhat sound.
Quite interesting to note that the author calls them only “somewhat” sound. What does that mean? A rather sloppy job writing it up…
