what does hydrogen gas do?
1. What does hydrogen do?
Hydrogen has many important uses and functions. It can not only be used as an industrial raw material and special gas, but also be used in the field of biomedicine to exert its antioxidant and anti-inflammatory effects. With the continuous development of science and technology, hydrogen is expected to play a greater role in future research and applications.
2. Is hydrogen harmful to the human body?
Hydrogen has no direct harmful effects on the body under suitable conditions.
Hydrogen is a colorless, odorless, non-toxic gas. Under normal circumstances, the human body is exposed to a moderate amount of hydrogen and will not cause harmful effects on the body. In fact, hydrogen is widely used in medicine and science, for example, hydrogen can be used as a medical gas to treat some diseases.
It should be noted that if the hydrogen concentration is too high and exceeds the normal range, or in special environments, such as high-concentration hydrogen leakage in a closed space, it may cause danger to the body. High concentrations of hydrogen may lead to dangerous situations such as suffocation and hypoxia. Therefore, when using hydrogen or in an environment where hydrogen may leak, it is necessary to strictly control the concentration of hydrogen to ensure safe use.
3. Why is hydrogen so important to life?
Hydrogen can eliminate toxic free radicals, hydrogen can activate the endogenous antioxidant system, and hydrogen can activate the expression of anti-aging factor SIRT, which proves that hydrogen may play an important role in anti-aging
4. Which products are made from hydrogen?
Basic hydrogen products have been perfected in the market, including hydrogenated food, hydrogen water, hydrogen water machine, hydrogen water cup, hydrogen bubble bath machine, hydrogen absorption machine, etc. Since the public’s awareness of hydrogen is far from enough, hydrogen The promotion of the industry will take some time, and the development of the hydrogen industry has just started.
5. Will hydrogen replace natural gas?
As far as the current situation is concerned, hydrogen cannot replace natural gas. First, the hydrogen content is low, and the hydrogen content in the air is quite small. The degree of enrichment is low, and it cannot be compared with natural gas at all. Second, the storage of hydrogen is very difficult, and the traditional high-pressure storage method is adopted. Not to mention light and energy consumption, the requirements for the material strength of the storage container are quite high. Hydrogen can only be liquefied at minus 250 degrees Celsius. It is conceivable that it is more difficult to solidify. Because there is still no material that can maintain high strength below minus 250 degrees. This is a bottleneck.
6. Why is hydrogen production so difficult?
1. High production cost: At present, the production cost of hydrogen is relatively high, mainly because a large amount of electricity is required to electrolyze water or extract hydrogen from natural gas. At the same time, storage and transportation of hydrogen also require a certain amount of cost.
2. Difficulty in storage and transportation: Hydrogen is a very slight gas that requires high pressure or low temperature for storage and transportation, and the leakage of hydrogen will also cause certain harm to the environment.
3. High safety risk: Hydrogen is an extremely flammable gas. If there is leakage or accident during storage, transportation, filling or use, it may cause serious safety accidents.
4. Insufficient market demand: At present, the scope of application of hydrogen energy is relatively narrow, mainly used in transportation, industrial production, energy storage and other fields, and the market demand is relatively low.
