The Society of Automotive Engineers (SAE) projects that in roughly 10 years, highways around the world will be home to over 2 million methanol-powered cars, with that number exploding to 35 million by 2020.

Examining how those millions of vehicles will get access to methanol is the focus of a paper to be presented by the American Methanol Institute at next month's SAE International Congress and Exhibition in Detroit.

The authors estimate that installing methanol pumps at one of every 10 existing fueling stations in the five states that will require zero-emissions vehicles by 2003 should cost $500 million.
