Customer ServiceOne of the most critical factors for consumers is driving range—the distance a vehicle can travel on a full charge or tank. Hydrogen cars have an advantage here, with ranges typically between 300 and 400 miles.
Customer ServiceDavid Cebon, a professor of mechanical engineering at the University of Cambridge, said: If you use green hydrogen it takes about three times more electricity to make the hydrogen to power a car than it does just to charge a battery. That could improve slightly but not enough to challenge batteries.

Figure 3 shows the different stages of losses leading up to the 30% efficiency, compared to the battery’s 70-90% efficiency, since the stages of losses are much lower than hydrogen. Since this technology is still under development and improvement, it is lagging in streamlining its production.
For hydrogen fuel vehicles, the hydrogen in the tank must be reconverted into electric power, which is done through fuel cell. According to the U.S. Department of Energy, the fuel cell technology has the potential of achieving 60% of efficiency, with most of the rest of the energy lost as heat (U.S. Department of Energy, 2011).
