Ultra-low sulfur diesel

Last Thursday, June 1, was the first step towards having cleaner diesel in the US. ULSD is now hitting the refineries and should be available to consumers in October. While current diesel engines will see a reduction in emissions (10%?), the real gain, a 90% reduction in emissions, will come when the next generation of diesel engines become available in the US.

It's about time that the US became serious about cleaner diesel. Why has it taken so long? The trucking industry. They wanted cheaper diesel. Well, I want a diesel that doesn't spew soot in the air and is a viable, more efficient alternative to gasoline. So there!

In the meantime, we may see less diesel cars available. VW is dropping its TDIs until 2008. And Chrysler has just announced that it is dropping the Jeep Liberty diesel. But expect to see a lot more diesel cars made available once our diesel matches Europe's. Car companies have known for a while how to make cleaner diesel engines, they've not been able to implement them in the US due to our dirty diesel.
