Hydrogen Fuel Limitations
On the Limitations of Hydrogen Fuel
In recent years, those who use hydrogen fuel have been looked up to as new energy. However, upon closer inspection, its existing limitations have not been able to replace all old energy sources.
The first word on the difficulty of making. Although hydrogen is widely distributed in the world, it is mostly found in water, fossil fuels and other materials. If you want to obtain pure hydrogen, you must use chemical methods, electrolysis methods, etc. to make it. Chemical methods rely more on fossil fuels and are used in hydrogen evolution. This does not get rid of the dependence on traditional energy sources, and generates greenhouse gases, which is contrary to the purpose of low carbon. Although the method of electrolyzing water can obtain high-purity hydrogen, it consumes a lot of electricity, and if the power consumption is taken from traditional thermal power, it is not a clean energy way.
The second discussion is the difficulty of storage. Hydrogen has the characteristics of small molecules, easy to escape, and wide range of explosion. To store it, high pressure and low temperature methods must be used. High-pressure hydrogen storage requires special high-pressure vessels, which are expensive and safe. If you are not careful, hydrogen will leak out and explode in case of an open flame, which is very dangerous. Low-temperature hydrogen storage needs to be reduced to extremely low temperature to liquefy hydrogen. This requires strict requirements for refrigeration equipment and heat insulation technology, and high energy consumption. In practical applications, it is not easy.
Furthermore, talk about the difficulties of transportation. Due to the special physical properties of hydrogen, its transportation is inconvenient. Pipeline transportation requires special pipelines, which require high leakage-proof, pressure-resistant and corrosion-resistant requirements, and the construction cost is not cheap. Vehicle transportation, whether it is high-pressure gas hydrogen or low-temperature liquid hydrogen, faces problems such as high energy consumption and low safety on the way, making it difficult to transport a large amount over long distances.
The end and the lack of supporting facilities. If hydrogen fuel is to be widely used, hydrogen refueling stations and other supporting facilities are indispensable. However, under today's circumstances, the number of hydrogen refueling stations is scarce, the cost of construction is high, and the technology is complicated. It is not easy to build alone, and the operation also requires a professional team and a mature system, which is an obstacle to the promotion of hydrogen fuel.
To sum up, although hydrogen fuel has potential, it has significant limitations in the production, storage, transportation and supporting facilities. To make it a mainstream energy source, it still needs scientific and technological breakthroughs to overcome these difficulties before it can be widely used.
