Hydrogen Cars vs Electric Cleanliness
The debate on the cleanliness of hydrogen cars and trams
In recent years, the debate between hydrogen cars and trams has gradually arisen, and people disagree on the cleanliness of the two.
When it comes to trams, when they are running, they have no exhaust emissions, are quiet and silent, and seem to be extremely pure. Because they are powered by electricity, if the electricity is taken from clean energy such as water power, wind power, and photovoltaics, the tram trip is almost zero pollution, which is very environmentally friendly. However, it also has hidden concerns. The manufacture of batteries requires mining and metallurgy, which requires a lot of energy consumption and generates a lot of pollution. Furthermore, the battery life is over, and improper disposal will become a new source of pollution, and chemical leakage can harm water and soil.
In contrast to hydrogen vehicles, hydrogen is used as a material, and only water is produced after the reaction, which can be described as clean. The production of hydrogen, if it is derived from renewable energy electrolysis of water, can also achieve the standard of low carbon. However, the reality is not satisfactory. At present, most hydrogen production still relies on the reforming of fossil fuels. This process not only consumes a lot of energy, but also emits greenhouse gases such as carbon dioxide. The storage and transportation of hydrogen is not easy, and it requires high pressure or low temperature conditions. The technical requirements are strict. If there is a little carelessness, it will cause safety risks.
To sum up, the cleanliness of hydrogen vehicles and trams cannot be broken solely by running time. It is necessary to monitor the whole life cycle, from energy extraction to vehicle scrap disposal. To achieve true cleanliness, both require advanced technology in order to go further in the path of environmental protection.
