Hydrogen can be used in fuel cells and is being explored as an alternative to gasoline, and has been for a number of years. The problems associated with hydrogen fuel cells are high fuel cost, low fuel availability (only sold in some places, and mostly in California), high vehicle cost (fuel cell vehicles are much more expensive than traditional gasoline-powered cars), low vehicle availability and onboard fuel storage, because hydrogen fuel cells only last about 300 miles. Some other challenges facing these fuel cells include low customer acceptance, safety hazards, low fuel cell performance and transport/bulk storage.
True enough, the hydrogen fuel cell has a long road ahead of it. Though efficient enough, it has been difficult to develop on the mass scale, due to high cost. These high coast stem from the components needed to make the fuel cell, a feasible storage system for on-board hydrogen, and making the system small enough for a commuter car. Also, a bigger problem is obtaining hydrogen without burning fossil fuels. Although hydrogen is the most abundant element in the known universe, its out there…outside our atmosphere. Hydrogen in its natural state is hard to come by on Earth, and so supply presents a problem, if the intent is to move away from fossil fuels.
