What Are the Pros and Cons?Air pollution. Vehicles that run on pure hydrogen are true zero-emission vehicles. Some vehicle manufactures, however, are developing fuel-cell vehicles that can run on hydrocarbons, such as methanol (a liquid fuel derived most commonly from natural gas) or gasoline. Using hydrocarbons to operate fuel-cell vehicles would result in tailpipe air pollutant emissions, reducing fuel cells' overall environmental benefits.
Global-warming pollution. Run on pure hydrogen, fuel cells consume no fossil fuels and emit no heat-trapping gases (which contribute to global warming). However, it is extremely important to factor in any global warming emissions associated with the production of hydrogen. Pure hydrogen gas does not occur in nature in concentrated amounts, meaning that hydrogen must be produced. A number of various technologies exist to extract hydrogen from sources such as water, natural gas, coal, and biomass, among others. The different hydrogen sources and production methods determine the amount of heat-trapping gases and other environmental issues associated with hydrogen production. Advances in hydrogen production are needed to minimize and eliminate global warming emissions. Research needs to continue on producing hydrogen from renewable resources, including wind and solar power and more advanced technologies.
Cost. Today's fuel-cell vehicles are mostly produced as prototypes or in very small quantities. As mass production often correllates to cost competitiveness, current costs are quite high. But the interest of automakers worldwide in developing these vehicles signals their belief that fuel cells will be competitive with conventional-technology vehicles. Increasing experience with advanced hybrid-electric vehicle technology and production will help lower the cost of future fuel-cell vehicles. Hybrid-electric vehicles use electric motors and advanced battery technology, both of which will be beneficial in fuel-cell vehicle development.
Performance and range. As with other electric-drive vehicles, fuel-cell cars are quiet, smooth, and fun to drive. A remaining challenge for fuel-cell vehicle developers is storing hydrogen onboard the vehicle. Because hydrogen is a gas, as opposed to a liquid fuel, a larger volume of it is needed to travel the same distance as with a tank of gasoline. A number of hydrogen storage technologies are being pursued to provide fuel-cell vehicles with a driving range equivalent to today's cars.
