They envision a growing use of electricity from wind and solar energy, which can separate hydrogen and oxygen in water. Yet proponents of hydrogen-powered transportation say that in the long run, hydrogen production is destined to become more environmentally safe. Indeed, a new study by researchers from Cornell and Stanford universities found that most hydrogen production emits carbon dioxide, which means that hydrogen-fueled transportation cannot yet be considered clean energy. That process pollutes the air, warming the planet rather than saving it. For now, the hydrogen that is produced globally each year, mainly for refineries and fertilizer manufacturing, is made using natural gas or coal.

To be sure, hydrogen remains far from a magic solution.

contributor to climate change, which is why hydrogen power, in the long run, is seen as a potentially important way to help reduce carbon emissions. Transportation is the single biggest U.S. So are makers of planes, trains and passenger vehicles. Manufacturers of large trucks and commercial vehicles are beginning to embrace hydrogen fuel cell technologies as a way forward. Hydrogen, the most abundant element in the universe, is increasingly viewed, along with electric vehicles, as one way to slow the environmentally destructive impact of the planet’s 1.2 billion vehicles, most of which burn gasoline and diesel fuel. They emit nothing but harmless water vapor. In place of pollution-belching diesel fuel, one-fourth of the agency’s buses run on hydrogen. Yet collectively, they reflect the cutting edge of a technology that could play a key role in producing cleaner inter-city transportation. The buses - made by El Dorado National and owned by the Stark Area Regional Transit Authority - look like any others. CANTON, Ohio - Each morning at a transit facility in Canton, Ohio, more than a dozen buses pull up to a fueling station before fanning out to their routes in this city south of Cleveland.
