Hydrogen Pros and Cons
The pros and cons of hydrogen energy
Hydrogen energy has become more and more important to the world in recent years. Because of its many advantages and advantages, it also has some drawbacks. The following analysis is as follows.
Its advantages are first and foremost clean and pollution-free. The combustion of hydrogen produces only water, and there is absolutely no discharge of substances that pollute the environment such as carbides and nitrides. In the current world of environmental worries and serious pollution, it is an ideal clean energy source, which can help reduce the greenhouse effect and maintain the purity of the atmosphere.
Second, the energy density is high. Compared with traditional fossil fuels, the energy contained in hydrogen is particularly considerable. In terms of unit mass, the energy released by combustion far exceeds that of gasoline, diesel, etc., which can provide longer power for power vehicles and improve the efficiency of energy utilization.
Furthermore, there are a wide range of sources. Water is an extremely abundant resource on the earth, and hydrogen can be produced by electrolysis of water; and progress has also been made in biological hydrogen production and other fields, such as hydrogen can be produced during the metabolism of some microorganisms, which is a source of hydrogen energy and a broad path.
However, hydrogen energy is not perfect, and its drawbacks are also obvious. First, the production cost is high. The current common electrolysis of water to produce hydrogen requires a lot of electricity. If this electricity comes from traditional thermal power, it will not only fail to show the advantages of hydrogen cleanliness, but also increase energy consumption and pollution. Other hydrogen production methods, such as coal gasification to produce hydrogen, also face the problem of cost and pollution.
Second, storage and transportation are difficult. The boiling point of hydrogen is extremely low, and it is gaseous at room temperature and pressure. To store it efficiently, it needs to be liquefied at high pressure or low temperature. This requires extremely high storage equipment and increases the cost of equipment. Moreover, during transportation, due to the special nature of hydrogen, special facilities and technologies are required, and safety risks cannot be ignored.
Third, infrastructure is lacking. To widely use hydrogen energy, infrastructure such as hydrogen refueling stations is indispensable. However, the number of hydrogen refueling stations is scarce today, which is far less common than that of gas stations. This poses a great obstacle to the promotion and application of hydrogen energy, causing consumers to have more inconvenience when using hydrogen energy vehicles.
In summary, although hydrogen energy has a bright future and is the hope for energy transformation, it is still necessary to overcome many technical and cost difficulties and improve the infrastructure in order to enjoy its benefits, avoid its drawbacks and promote the sustainable development of the energy system.
