The Cost of Hydrogen Vs. Gas

BY MICHAEL BAKER

Constant fluctuations in the price of gasoline as well as environmental concerns in burning fossil fuels leads more drivers to consider vehicles that use alternative fuels. Hydrogen is one such fuel that has the potential to be a cheaper, more efficient and cleaner alternative to gasoline. Although hydrogen-powered fuels have been under development for decades, they still remain in the short-term a much more expensive option than gasoline-powered cars.

Identification

While gasoline remains the predominant fuel source for automobiles, hydrogen-fueled vehicles already are available for consumer use. Most of these are in California, where as of 2009, about 300 hydrogen-fueled vehicles are in use. Fuel cell tester Powertech estimates there will be more than 4,000 such vehicles in use as of 2014. GM, Honda, Hyundai and Nissan all have hydrogen-fueled cars in some phase of development. Because of the high cost and time involved in developing these vehicles, however, many manufacturers have scaled back research and development on them as they struggle with their own solvency.

Features

Pound for pound, hydrogen fuel cells contain three times the energy of gasoline, according to the U.S. Department of Energy. Were hydrogen fuel widely produced, it would cost the equivalent of $2 per gallon, according to U.S. News & World Report. This is well below the average price of gasoline in the United States as of 2010. High efficiency--current models can get about 70 miles per gallon--and low emissions further enhance the value of hydrogen-fueled cars.

Considerations

While hydrogen is a cheaper fuel than gasoline on paper, the reality is, as of 2010, it is much more expensive. The few models of hydrogen-fueled cars that are commercially available generally cost more than $100,000. Researchers are still tweaking the technology to produce and transport hydrogen fuel. Thus, fueling stations are limited, making the cost of hydrogen fuel vary widely

Answer 2

Well the simple answer is that hydrogen is expensive and difficult to obtain also it has low ignition temperature and so is highly flammable and dangerous and difficult to use and transport
