Advantages and disadvantages of hydrogen powered vehicles
Advantages: Emissions are pure water and do not produce any contaminants when driving.
Disadvantages: Hydrogen fuel costs are too high, and the storage and transportation of hydrogen fuel is very difficult according to technical conditions, because the hydrogen molecules are very small and easily escape through the outer casing of the storage device. In addition, the most deadly problem is that hydrogen extraction requires electrolysis of water or the use of natural gas. As a result, it also consumes a lot of energy. Unless it is extracted by nuclear power, it cannot fundamentally reduce carbon dioxide emissions.
