The possibility of home production and usage of fuel cell technology for high-efficiency, zero-emission electric vehicles has sparked interest in hydrogen as a fuel for transportation. A fuel cell has up to three times higher efficiency than a gasoline-powered combustion engine, as written in the journal Energies. Fuel cell technological advancements are mostly focused on the use of hydrogen in cars.

Several automobile manufacturers in the United States have begun to provide light-duty hydrogen-powered electric vehicles in areas where hydrogen fueling stations are available, such as Southern and Northern California.
