New energy vehicle hydrogen power
Hydrogen-powered vehicles are a truly zero-emission means of transportation, which emits pure water, which has the advantages of no pollution, zero emissions, and abundant reserves. Therefore, hydrogen-powered vehicles are the most ideal alternative to traditional vehicles. Hydrogen-powered vehicles cost at least 20 percent more than conventionally powered vehicles. China Changan Automobile completed the ignition of China's first high-efficiency zero-emission hydrogen internal combustion engine in 2007, and exhibited its self-developed China's first hydrogen-powered concept sports car "Hydrogen Journey" at the 2008 Beijing Auto Show.
With the gradual formation of the "automobile society", the number of automobiles continues to show an upward trend, while resources such as oil are stretched. On the other hand, vehicles that swallow a lot of gasoline continue to emit harmful gases and pollutants. The ultimate solution is of course not to restrict the development of the automobile industry, but to open up new energy sources that can replace oil. The four wheels of the fuel cell vehicle roll quickly and quietly across the road, rutting out the name of the new energy source—hydrogen.
Almost all the world's auto giants are developing new energy vehicles. Electricity was once considered the future power of the car, but the long charging time and weight of the battery has made people gradually lose interest in it. In 2009, the hybrid electric vehicle that combined electricity and gasoline could only temporarily alleviate the energy crisis, and could only reduce but not get rid of the dependence on oil. At this time, the emergence of hydrogen-powered fuel cells is like rebuilding a Noah's Ark, allowing people to see infinite hope from the crisis.
The idea of using hydrogen as a fuel for cars was scary when it first came out, but it actually has some truth to it. Hydrogen has a high energy density, and the energy released is enough to run a car engine, and the chemical reaction between hydrogen and oxygen in a fuel cell produces only water and no pollution. Therefore, many scientists predict that the fuel cell using hydrogen as energy is the core technology of automobiles in the 21st century, and its revolutionary significance to the automobile industry is as important as the microprocessor to the computer industry.
Advantages: The discharge is pure water and does not produce any pollutants while driving.
Disadvantages: The cost of hydrogen fuel cells is too high, and the technical conditions for the storage and transportation of hydrogen fuel are very difficult, because the hydrogen molecules are very small and can easily escape through the shell of the storage device. In addition, the most deadly problem is that the extraction of hydrogen requires electrolysis of water or the use of natural gas, which also consumes a lot of energy. Unless nuclear power is used to extract it, carbon dioxide emissions cannot be fundamentally reduced.
