hydrogen

Fifteen years ago, the California and British Columbia governments sketched bold plans for a "hydrogen highway" for clean cars stretching from Whistler, B.C., to the Mexican border. California's then-governor Arnold Schwarzenegger drove a Hummer converted to run on hydrogen. Vancouver city officials pictured travelers to the 2010 Winter Olympics leaving only water vapor exhaust in their wake.

But Oregon and Washington state didn't warm to the idea. There are still no public fueling stations for hydrogen cars in either state. (Schwarzenegger replaced his hydrogen-fueled Hummer with an electric Mercedes-Benz SUV in 2017.)

An electric utility in north central Washington wants to branch out into hydrogen fuel production. It would be the first of a group of power companies in the Pacific Northwest to use their dams to make "renewable hydrogen."
