Hydrogen Vehicles Pros Cons
On the advantages and disadvantages of hydrogen energy vehicles
Hydrogen energy, the energy that has been developed in modern times, is also used for vehicles, and the advantages and disadvantages coexist as follows.
1. The advantages of hydrogen energy vehicles
(1) Clean and environmentally friendly
When hydrogen energy vehicles are in operation, their only emitter is water. Unlike traditional fuel vehicles, they emit pollutants such as carbon oxides, nitrogen oxides, and particulate matter, which harm the atmosphere, cause frequent smog, and harm human health. The promotion of hydrogen energy vehicles can make the sky bluer and the gas cleaner, which is greatly beneficial to the environment.
(2) High energy efficiency
Compared with traditional fuel oil, hydrogen has a high energy density. Although hydrogen energy vehicles have losses in the energy conversion process, the overall energy utilization efficiency is still considerable. And the fuel cell system can efficiently convert hydrogen energy into electric energy to drive the vehicle. Compared with the internal combustion engine, the energy conversion path is simple and efficient.
(3) Good battery life
Many electric vehicles today are often trapped in short battery life. And hydrogen vehicles, when the hydrogen storage is sufficient, can rival traditional fuel vehicles. When refueling, it is also fast, unlike electric vehicles, which take a long time to charge. This characteristic makes hydrogen vehicles quite advantageous in long-distance travel or operation vehicles.
Second, the disadvantages of hydrogen vehicles
(1) High cost
The first one is the high cost of hydrogen production. The current mainstream hydrogen production methods, such as fossil fuel reforming, although the technology is mature, it requires a lot of fossil energy and is accompanied by carbon emissions; while water electrolysis hydrogen production, although clean, but the cost of electricity remains high. Secondly, the cost of the vehicle itself is also high. Core components such as fuel cell systems and hydrogen storage devices are technically complex and expensive to develop and produce. The price of hydrogen vehicles is much higher than that of traditional fuel vehicles and electric vehicles, which discourages consumers.
(2) Lack of infrastructure
The construction of hydrogen refueling stations is difficult and expensive. Professional equipment is required, such as hydrogen compression, storage devices, etc., and huge investment is required in the early stage. And the location of hydrogen refueling stations, safety regulations and other issues also need to be properly resolved. At present, the number of hydrogen refueling stations is scarce, far less than the popularity of gas stations and charging piles, which seriously restricts the promotion of hydrogen vehicles. Without complete infrastructure, hydrogen vehicles can travel like boats without water, and it is difficult to move an inch.
(3) The safety is questionable
Hydrogen, flammable and explosive gases. Although the vehicle is designed with multiple safety protection measures, such as special design of hydrogen storage tanks, leakage detection devices, etc. However, in the process of hydrogen refueling, hydrogen storage and vehicle operation, once the protection fails, hydrogen leakage, exposure to open flames or static electricity, can easily cause explosions, threatening personal and property safety. This safety issue is a concern for the public, and it also requires continuous technological improvement to solve it.
To sum up, although hydrogen vehicles have the advantages of clean and environmental protection, high energy efficiency, and good battery life, the drawbacks of high cost, lack of facilities, and safety concerns are also significant. To make hydrogen vehicles popular in the world, researchers need to make unremitting efforts to reduce costs, build facilities, and improve safety in order to open up their broad prospects.
