【Is Hydrogen energy not completely environmentally friendly? Is it all just a fake and promotional tactic? Can it have the same effect as trees? 】
Last time we talked about the history of hydrogen, I believe everyone has started to learn more about hydrogen, knowing that it is a new energy source and very environmentally friendly. But is this really the case? Let me guide you to uncover this mystery!
The impact of global warming is approaching us. Countries are starting to implement regulations targeting fossil fuel vehicles, and even ban them in the future. With the development of electric vehicles and hydrogen fuel cell vehicles, countries are moving towards a zero-emission world.
Hydrogen-powered vehicles are known as the ultimate environmentally friendly vehicles. The principle of hydrogen fuel cells obtaining power is not through burning hydrogen gas, but through a chemical reaction between hydrogen and oxygen, and producing energy, which is then converted into kinetic energy and transferred to the wheels. The by-product of this process is water. This means that hydrogen fuel cell vehicles do not emit any pollutants. Burning hydrogen is one of the directions for using hydrogen. Hydrogen gas produces gaseous water when burned, and hydrogen can be produced from water. It’s a continuous cycle that is inexhaustible. Although no pollutants are generated during use, the process of separating hydrogen may produce greenhouse gases and air pollutants. However, if renewable energy is used to produce electricity for hydrogen separation, it can help to achieve reduction of gas emissions at the source.
The use of hydrogen can also have air purification functions because the propulsion of hydrogen vehicles is based on the electrochemical reaction between hydrogen and oxygen to generate electrical energy. When the hydrogen fuel cell of a hydrogen vehicle is supplied with external air, 99.9% of carbon dioxide and particulate matter in the air are removed in advance. How is the effect? When 10,000 hydrogen vehicles are driving on the streets at the same time, it can achieve a purification quantity equivalent to 600,000 trees, providing fresh air for 40,000 adults to breathe. Not only do they not emit pollutants during use, but they can even purify the air during use.
Are you surprised that hydrogen-powered vehicles can also clean the air ? After learning about the benefits of hydrogen-powered vehicles, what will the situation be like when they are actually used ? I will explain the safety of hydrogen-powered vehicles in our next post. If you want to learn more about the small details of hydrogen energy, be sure to stay tuned with us.
