New energy water fuel, also known as water-based fuel or vegetable oil fuel, is a new energy substitute. The principle is that fatty glycerides in vegetable oil react with water to produce glycerol and sodium fatty acid, and then the sodium fatty acid is converted into fuel through a catalyst.

Water-based fuel has the characteristics of environmental protection, safety, high calorific value, energy saving and renewable. Compared with traditional petroleum fuel, water-based fuel produces less pollutants such as sulfur dioxide, nitrogen oxides and particulate matter, and has less impact on the environment. At the same time, because of its renewability, water-based fuel has advantages in resource utilization and environmental friendliness.
