STUTTGART, Germany — At the Mercedes-Benz headquarters here, a showroom display illustrates the rapid evolution of the iconic luxury brand’s hydrogen-fueled cars.
In a 1992 prototype, the fuel cell takes up the entire cargo area of a delivery van. Across the room, today's model — now merely the size of an average television set — is displayed in front of a neon-lit outline of a compact passenger car. This “zero emission” engine, it appears, is ready for prime time. With the aid of government spending and joint efforts by Ford and Nissan, Daimler — Mercedes’s parent corporation — aims to start selling hydrogen-fueled cars to the public as early as 2017. If they take off, the biggest impact may be felt not in the car industry but in wind energy. Experts say a large commercial market could enable green energy producers to use their excess power to make clean hydrogen instead of storing it in costly batteries.
The selling points for consumers are strong. That doesn’t mean the going will be easy. Symmetry Magazine.
