Debating California's 'Hydrogen Highway'

"The artery of fuel stations known as the hydrogen highway that Gov. Arnold Schwarzenegger predicts will take California motorists to the environmental future is already taking shape. Twenty-one of the 200 stations are scheduled to be in operation by year's end. With the public sector pledging to pick up most of the $100 million cost, meeting the governor's 2010 target date will be the easy part. Much more difficult than building stations at 20-mile intervals along California's interstate highways will be providing consumers with hydrogen-powered vehicles and fuel at prices they can afford."
