Hydrogen fuel characteristics

Hydrogen is a colorless gas. Burning one gram of hydrogen can release 142 kilojoules of heat, three times that of gasoline. The product of its combustion is water, without ash and waste gas, and will not pollute the environment. The weight of hydrogen is very light, it is much lighter than gasoline, natural gas, and kerosene, so it is less convenient to carry and transport, but hydrogen as a fuel is still considered to be the most ideal energy source in the 21st century. The outstanding features of hydrogen fuel as an energy source are pollution-free, high efficiency, and recyclable utilization.
