[Ocean Hydrogen Energy] Is hydrogen energy safe?

Thread Content

Is hydrogen safe? Since hydrogen energy has so many advantages, everyone may ask, is it dangerous to use hydrogen energy now? In fact, hydrogen energy as a fuel always has certain dangers, and its smell after burning is not poisonous. We often see fire and explosion scenes. The toxic gas has knocked people down before they come into contact with the fire. But hydrogen does not have this problem. In addition, in terms of the explosiveness of fuel, the diffusion speed of hydrogen is 12 times that of gasoline. It can spread quickly and may cause a fire, but it will not cause other more serious consequences. When gasoline and hydrogen fuel vehicles are caught in fuel fire conditions respectively, hydrogen fuel vehicles will emit a fire as soon as the hydrogen burns and spread quickly. ； As for gasoline cars, there is nothing they can do. They can only burn, and the gasoline has no time to spread. In the end, all gasoline cars were burned down to their skeletons, while hydrogen fuel cars did not present any other dangers and could not hurt anyone. So in fact, in terms of safety, hydrogen fuel is slightly safer than gasoline. We have used hydrogen before, and everyone has been exposed to hydrogen. When hydrogen is used as a reducing agent, the dosage is small and there is nothing unsafe. But now that hydrogen needs to be used as an energy source, it needs to be used in large quantities and it can enter the common people. The common people are afraid that this hydrogen may explode, and even hydrogen balloons will explode. For example, there was a hydrogen refueling station built in a place before, but now it is no longer in use. If the hydrogen refueling station needs to be moved, no one dares to move it, and no one dares to approve it. Seven years later, this hydrogen refueling station has not been moved, but the place to be moved * * I don’t agree, and I don’t know who will approve it. In fact, hydrogen is not that dangerous. China’s pipeline network for transporting hydrogen is about 400 kilometers long. In the future, the pipeline network will be very long. When transporting hydrogen on the road, we used to go to hydrogen refueling stations to refuel. After the hydrogen arrived, we were not allowed to refuel during the day. We were only allowed to refuel at 12 o'clock in the middle of the night, for fear of safety problems. The establishment of a hydrogen system is to formulate absolutely safe hydrogen operating rules. Of course, since it is fuel, we must set rules, but it is still quite dangerous, especially during the initial promotion period, so special attention must be paid. Just like when we used oxygen in the 19th century, it was very dangerous at first. After all the rules are set, you won't feel nervous even if you sleep on an oxygen pillow at night. Therefore, if hydrogen standards are set well and the entire hydrogen usage rules are followed, there will be no danger. It turns out that there is a certain reason why we regard it as a hazardous chemical, because its usage is not large, people do not have a unified understanding of it, and there are no systematic standards. If it is used as a large energy source, it can actually re-formulate the rules for use and formulate rules and standards for hydrogen transportation, hydrogenation, hydrogen storage, and hydrogen production. This is actually safe. What I see now is a picture of a Japanese hydrogen fuel cell vehicle being refueled at a hydrogen refueling station. The hydrogen refueling station and the gas station are only separated by a wall. This is the gas station, this is the hydrogen refueling station. A Honda car is refueling, and behind it is the community. There is nothing dangerous.
