New energy hydrogen fuel is a kind of liquid hydrogen fuel. The new energy hydrogen fuel has the characteristics of high energy density and environmental protection. The main advantage of new energy hydrogen fuel is that its combustion product is water, and it will not produce substances that pollute the environment, such as carbon dioxide, carbon monoxide or particulate dust. In addition, hydrogen fuel is light in weight and relatively convenient to carry and transport. However, the use and storage of hydrogen fuel still need to be safe, because hydrogen is flammable and explosive. The production methods of hydrogen energy mainly include electrolytic water, natural gas reforming and biomass fermentation, in which electrolytic water decomposes water into hydrogen and oxygen, which requires a lot of electricity, while natural gas reforming and biomass fermentation convert natural gas or plants, wood and other biomass into hydrogen and carbon dioxide. Hydrogen energy is also used in hydrogen fuel cell technology, which converts hydrogen into electric energy to drive the motor to work, thus driving the vehicle.
