A few days ago, Tesla CEO Musk announced on social media that the first Tesla hydrogen energy car will be launched in 2024 and named Model H, but whether this is really yet to be examined, after all, two years ago it publicly opposed hydrogen energy, and said that hydrogen energy is a "fool", plus the tweet was released on April Fool's Day, the authenticity is more of a question, but this also makes hydrogen energy reappear in the public eye, today we will talk about hydrogen energy.
In fact, the topic of hydrogen energy has been raised for a long time, and has always been known as the ultimate energy source for mankind, and hydrogen energy seems to have better development opportunities. The first is that the price of electric vehicles is now rising, and the national subsidies for electric vehicles are not as large as before, on the contrary, in the second half of 2023 or 2024, the state will begin to subsidize hydrogen energy.
Another reason is that on March 23, the National Development and Reform Commission and the Energy Bureau jointly issued a series of policies such as the "Medium and Long-term Planning for the Development of hydrogen energy industry (2021-2035)", and the hydrogen energy strategy was upgraded to a national strategy for the first time, which further determined the status of hydrogen energy in the future and provided a guarantee for the development of hydrogen energy.
Regarding the use of hydrogen energy in automobiles, there are currently two main types, one is a hydrogen internal combustion engine car, which generates power by burning hydrogen, similar to fuel vehicles; the other is a hydrogen fuel cell vehicle, which generates electricity in the battery through hydrogen and oxygen in the air, which is converted into kinetic energy.
The reason why hydrogen energy will become the focus of everyone's attention is mainly due to the advantages of hydrogen energy itself. The first is more environmentally friendly, hydrogen energy vehicle exhaust only emits water, no other pollutants, and will not involve greenhouse gases, which is a great benefit to protect the environment, but also more in line with the mainland's environmental protection policies.
Secondly, hydrogen energy is more efficient, and high efficiency here refers to the high efficiency of charging. At present, a pure electric vehicle to fill the power may take several hours, the mileage anxiety of electric vehicles should be more accurate to say that it should be charging anxiety, especially during the holidays, the number of people traveling becomes larger, and if you want to charge the car, you have to queue up for a long time, and before the technology is not much improved, if you want to improve the efficiency of charging, there will be other safety hazards. In contrast, hydrogen energy vehicles only take a few minutes to fill up with hydrogen, which is very similar to fuel vehicles.
The third point is about the safety of hydrogen energy. Based on the current means of storage, hydrogen energy is actually very safe, before the Internet has been on the gasoline car and hydrogen energy car leakage ignition test, hydrogen energy battery car flame is only from the trunk upward channeling, a minute later the change is not much; and the fuel car first caught fire at the bottom, a minute later there is only an empty shelf left.
Of course, hydrogen energy also has a lot of dilemmas. For example, the way to make hydrogen is not environmentally friendly, although hydrogen itself is very environmentally friendly, but the production process can only be through chemical reactions, this process will produce some greenhouse gases, if it is the use of electrolysis, it is necessary to consume a lot of electricity, it is estimated that a kilogram of hydrogen needs to consume 48 degrees of electricity.
In addition, the cost of hydrogen energy is also very high, and the current cost of a hydrogen fuel cell vehicle is about 1.5-4 times that of lithium-ion electric vehicles and fuel vehicles. And although the above mentioned the safety of hydrogen energy, but this is more refers to the storage of hydrogen energy, which requires a lot of technical investment to ensure, the production cost of the container is quite high, and the current hydrogen refueling station revenue and expenditure is still in a state of loss, but also need a larger market size to support its development, which may not be easy to achieve in a short period of time.
summary:
In any case, the development of hydrogen energy is already a certain fact, but hydrogen energy wants to have a better development, stepping up to overcome the technical problems in manufacturing, storage, transportation and other aspects is a key, and from the current situation, hydrogen energy wants to become the mainstream energy in the future under the wind outlet of new energy development There is still a long way to go.
