Tom Albert drove his loaner Chevrolet Equinox like any other car. He took it to work during the week, picked up groceries, and loaded up the back with bags of soil at the garden store. When his infant son was fussy, Albert drove the newborn around the block to calm him down. The normal driving experience ended, however, when it came time to fuel the car. Aboard the silent vehicle, Albert had two filling stations to choose from in the Washington, D.C., area, and the fuel—hydrogen—was anything but typical.
