On the Disadvantages of Hydrogen Energy Vehicles
In recent years, many people have studied the way of travel, and hydrogen energy vehicles have also become popular. However, after closer inspection, hydrogen energy vehicles have all the drawbacks, which is not an ideal choice.
Bearing the brunt, hydrogen production is difficult and consumes a lot. Today's hydrogen production relies more on fossil fuel reforming or water electrolysis. Although fossil fuel reforming is a common method, it is difficult to remove carbon emissions and does not meet today's low-carbon vision. Hydrogen production by water electrolysis, although pure and net, consumes a lot of energy, and it requires electricity or traditional energy, which also increases carbon emissions. And the construction and operation of hydrogen production equipment are expensive, resulting in high hydrogen production costs.
Second, the risk and complexity of hydrogen storage. The characteristics of hydrogen are very different, its ignition point is low, the explosion limit is wide, and storage and transportation require extremely high safety requirements. High-pressure gaseous hydrogen storage requires special high-pressure vessels, which are expensive and take up space; low-temperature liquid hydrogen storage, although the density increases, requires an extremely low temperature environment, which requires huge energy consumption and complex equipment. Furthermore, the construction of hydrogen storage facilities requires a large investment and long cycle, and the popularization of hydrogen refueling stations is far from easy to reach gas stations, which greatly hinders the battery life and convenience of hydrogen energy vehicles.
Again, hydrogen fuel cell technology is not yet complete. Its durability is insufficient. After repeated charging and discharging and working conditions change, the performance is easy to decline, resulting in short battery life, frequent replacement, and increased user costs. And the fuel cell starts slowly, especially in low temperature environments, making it difficult to cope with sudden travel needs. In addition, core materials such as proton exchange membranes and catalysts rely on imports, which makes the supply unstable and also hinders the development of the industry.
Finally, the economic benefits are not obvious. Hydrogen energy vehicles have high R & D and production costs, resulting in expensive prices. Compared with traditional fuel vehicles and pure electric vehicles, the cost performance is low. Although the government may have subsidies, it is difficult to survive without subsidies in the long run, and the market competitiveness is weak. And the industrial supporting facilities are not complete, the maintenance is inconvenient, and the supply of parts is in short supply, all of which increase the burden on users.
To sum up, hydrogen energy vehicles have many drawbacks in hydrogen production, hydrogen storage, technology and economy. At present, it is difficult to be the best option for travel. When technological breakthroughs, costs are reduced, facilities are complete, or improvements may be made, it is not an exaggeration to call it a bad idea.
