When it comes to new energy electric vehicles, the first thing that comes to mind is lithium battery electric vehicles, and everyone is still very unfamiliar with hydrogen battery vehicles. But in terms of environmental protection and energy conversion efficiency, hydrogen battery vehicles are stronger than lithium batteries! But hydrogen batteries have been developed for a long time and have not replaced lithium batteries for a long time.
First, the cost of hydrogen power production is high
The raw materials of hydrogen electricity are mainly hydrogen atoms and compounds, and hydrogen atoms are combined with oxygen atoms to decompose into water through combustion, and there are no carbon atoms in the middle, so it is very environmentally friendly. But since hydrogen is a reactive element, it is also flammable and explosive. Although there are many in nature, it is difficult to produce, and the cost of hydrogen batteries is very high.
Second, it is very difficult to store hydrogen electricity
Hydrogen atoms are also very difficult to store because of their liveliness, and they are more likely to explode if they encounter open flames, or high temperature and high pressure. Hydrogen batteries stored at the same time require special storage or space. Therefore, it is relatively difficult to promote and apply it on a large scale
Third, the advantages of hydrogen power exchange are gradually being lost
The way to replace the battery of hydrogen battery is as simple as refueling, but with the development of lithium battery fast charging technology, lithium batteries can also achieve hundreds or even thousands of kilometers of energy replenishment within 5 minutes in the future. Especially after the launch of the 800V platform, everyone is no longer so anxious about the battery life of electric vehicles, so that its only shortcoming has been made up!
Fourth, the hydrogen power infrastructure is relatively backward
From a global point of view, most countries are studying lithium battery routes, and a large amount of infrastructure is carried out around lithium batteries, such as charging piles distributed across the country, electric vehicle swap stations, etc. However, there is very little infrastructure for hydrogen batteries, and even if people buy hydrogen electric vehicles, it is very troublesome to recharge them.
Summary:
In the foreseeable 30 to 50 years, lithium batteries will still play a major role in the electric vehicle market, hydrogen electric vehicles can only be a supplementary energy method, and it is very difficult to become a mainstream new energy. However, there is no substitute for the environmental friendliness of hydrogen batteries. Guys, what do you think about this?
