"The Hydrogen-Powered Era Is Almost Upon Us. But Is There A Market?"

"GOLDEN, Colo. -- Two months ago, the Department of Energy trailered in a white, fish-shaped, 210-square-foot house and a dark jeeplike vehicle to put them on display here. The vehicle had an electric motor, a battery and a small gas-fired generator that could power the house, and the house had solar panels integrated into its rooftop that could power the car.

Arriving with the exhibit at the National Renewable Energy Laboratory (NREL) was David Danielson, an assistant secretary for DOE, who explained that the vehicle and the house were meant to stimulate thought among the agency's network of 17 research laboratories and among its industry and university partners that are working on various projects to promote renewable energy, including the overhaul of the American power grid.

Danielson outlined various national challenges, beginning with the fact that the United States will have 33 percent more electricity users by 2050 and that it has pledged to cut greenhouse gas emissions 80 percent by then to limit the threats of global warming."
