With the use of two fuels in the automotive industry, which environmental protection is hydrogen energy fuel cell vehicle and pure electric vehicle?
1. The principle of use of power and energy raw materials
The hydrogen energy fuel cell vehicle can achieve zero pollution for the environment. The use of solar energy to break down water. The hydrogen fuel cell first consumes a lot of electrical energy. Under the action of a catalyst, the hydrolyzed Replace fossil fuels to minimize the greenhouse effect. However, the produced hydrogen needs to be transported by high -pressure hydrogen tanks or low -temperature technology, which is not only dangerous, but also costs higher cost.
Pure electric vehicles in the development direction of many car companies, mainly consisting of three major parts of motor, electrical control, and battery. Its working principle is to provide current from the battery to the electrical control system. The wheels let the car drive. Pure electric vehicles have a stronger Well -to Wheel "oil well to wheel" efficiency, which is about 2-3 times that of gasoline vehicles, and power plants can also centrally deal with pollution emissions. The emission is obviously much lower, but it will not "zero emissions emissions emissions "".
In terms of the principle of power energy raw materials, the basic energy raw material of hydrogen energy is hydrogen, which can be extracted from water. The heat is large and the discharge is still water. One characteristic of hydrogen energy is to control and utilize the source at the source and do not increase the burden of other industrial chains.
2. In terms of energy raw materials reserves
It is estimated that it constitutes 75%of the quality of the universe, and it is mainly stored in water in the morphology of compounds, and water is the widest material on the earth. According to calculations, if all the hydrogen in the seawater is extracted, the total heat generated by it is 9,000 times larger than the heat released by all fossil fuels on the earth.
The production of electric vehicle batteries requires one -performance energy. The power generation technology relied on electric vehicles has also been upgraded and innovated with the changes in the times. Although thermal power has always dominated, in recent years, the improvement of renewable energy power generation has been very fast. Essence As the proportion of renewable energy in the use of generators continues to increase, the proportion of "clean energy" in electric vehicles will continue to increase in the future.
It can be seen that hydrogen energy fuel batteries and pure electric vehicles have long -term development prospects.
3. In terms of energy consumption and waste treatment
The heating value of the hydrogen energy fuel cell is 142351 KJ/KG, which is 3 times the heat -feeding value of gasoline. It is the highest among all fossil fuels, chemical fuels and biofuels except nuclear fuel. Electric vehicles take Tesla as an example. Its maximum battery life is about 430km. It can be charged through Tesla super charging piles. It can provide about 300 kilometers of mileage in 30 minutes. The maximum range of Clarity hydrogen fuel vehicles launched by Honda can reach 700km, which can be fully fulfilled in only 3 minutes. In addition, hydrogen energy vehicles can be charged quickly, and Japan's research test states that the hydrogen fuel cells in the scrapped hydrogen energy fuel cell vehicles can be removed and installed in the new car to continue to use it.
However, for electric vehicles, the current technology of electric vehicles clean energy is constantly developing, but the processing problem of the later period of battery is still a very difficult problem. The toxic waste produced by the battery production process, a large number of waste battery treatment methods, facing the face of the method of processing the battery, facing the face of the method of processing the battery, facing the face of the method of processing it. The battery is a problem of heavy metal pollution source. Under normal circumstances, heavy metals themselves are almost insoluble in water, and it is not easy to pollute the soil through rust. However, when attached to the battery, the heavy metals inside the battery after the battery are in a soluble -soluble state or simply ion. Essence Even if there are some pollution in part of the hydrogen manufacturing, "green hydrogen" exists objectively.
In general, for the three levels of waste discharge, energy raw materials, and waste treatment, hydrogen energy fuel cell vehicles are relatively environmentally friendly.
