Electric Vehicles Take Center Stage at Auto Show, But Other Technologies Not Forgotten

As the 2009 North American International Auto Show comes to a close this weekend, there’s no doubt it has been decidedly about electric propulsion this year, especially for GM with the production Chevy Volt, the concept Cadillac Converj and battery pack manufacturing in Michigan.

Which leads to a fair question of contrast with the 2008 auto show: Where is ethanol? Last year’s press days largely revolved around the promise of cellulosic ethanol with GM’s investment in Coskata.

But when you think about it, the technology news at the auto show rarely has the same emphasis in back-to-back years any more than the Super Bowl features the same teams from one year to the next. GM has multiple approaches to advanced propulsion, including improved internal combustion engines, flex-fuel, hybrids, battery-electric, and hydrogen fuel cells. All have significant dedicated engineering resources, and the best stories – like the best football teams playing on Super Bowl Sunday – are told at the auto shows.

In 2006, ethanol made it big with the “Live Green, Go Yellow” commercials that kicked off during Super Bowl XL, followed by heavy promotion of corn-based ethanol for flex-fuel vehicles the next week at the Chicago Auto Show.

In 2007, electrification was the buzz word as GM showcased the Volt concept for the first time with what we now call the Voltec electric propulsion system. The Volt concept highlighted both battery-electric and hydrogen fuel cell sources because both will be integral in the future. And the Volt production vehicle will also be available with a flex-fuel engine.

You’ve heard the GM mantra that “there is no silver bullet” for advanced propulsion. Technology is not forgotten because it doesn’t get a huge push during auto show season.

Removing the automobile from the energy debate will require multiple energy pathways because some propulsion technologies are simply better suited to certain types of vehicles and driving activities.

As for ethanol, most of the effort by producers today is focused on biomass – plants, grasses and wood waste that are not used for food. Two commercial plants are on target for 2011 startup and a handful of others are reaching the pilot stage. Corn is still the primary source for ethanol, which is blended at 10 percent into most gasoline and mixed with 15 percent gasoline to be sold as E85.

Despite the recent price inversion which has made wholesale gasoline cheaper than ethanol, the number of fueling stations offering E85 or installing pumps to handle it is growing – recently passing 1,900 according to the National Ethanol Vehicle Coalition. In Illinois alone, there are 205 stations offering E85 compared with 166 a year ago.
