In fact, to vigorously develop hydrogen energy, we must solve these three problems.
First, the manufacturing cost.
At present, the cost of hydrogen production from synthetic ammonia is quite high, whether it is hydro-hydrolysis or ammonia synthesis. Instead of using electrolyzed water to produce hydrogen, it is better to get rid of middlemen and use electricity directly.
Second, danger.
We have learned in junior high school physics that hydrogen is flammable and explosive, and its flammable and explosive degree is much higher than that of natural gas, so storage and transportation are extremely dangerous. At present, LNG filling stations are all built in suburbs, not to mention urban areas.
Third, patented technology.
At present, 80% of the patented technology of hydrogen energy is monopolized by Japan and South Korea. If we vigorously develop hydrogen energy, we will continue to harvest our wool for them, just like the current fuel trucks.
Therefore, it is hard to say whether electric vehicles will be in the future, but the next 20 or 30 years that can be seen will definitely be the world of electric vehicles.
And those who say we give up hydrogen energy research and development, take a good look at the policy. At present, our policy is to encourage cars to develop pure electric vehicles and encourage large transport trucks to switch to hydrogen energy. Therefore, the policy should understand that the future is not the world of hydrogen energy vehicles!
