Bush: ‘Hydrogen is the Fuel of the Future’

President Bush had an Earth Day message for drivers worried about soaring gasoline prices: The nation must move more quickly toward widespread use of hydrogen-powered cars.

Running vehicles on hydrogen fuel cells would help reduce oil consumption, as the technology does not require gasoline, and lower pollution, as water is the only emission. But the technology is far from being a reality in the marketplace: The cells are prohibitively expensive and require a new distribution system to replace today’s gas stations.
