Tomorrow, let's "hydrogen in the battlefield" together!

After watching the first episode of "Exploring the" Better "of" Detective "Carbon", many people can't help asking: How will hydrogen energy affect our lives? Will hydrogen vehicles replace electric vehicles? Below, let's find out the shots of Xinhua Daily · Jiao Dian Journalists.

The reporter experienced "hydrogen energy riding" on the spot

In the product exhibition hall of Ji Cui Antai Chuangming Advanced Energy Materials Research Institute in Changzhou, there is a row of the latest type of hydrogen -sharing motorcycles. After scanning the QR code to unlock the motorcycle on the body, the reporter experienced a "hydrogen energy cycling" on the road. Compared with traditional electric bicycles, hydrogen energy motorcycles are light and clever, very easy to control. It is convenient to use brakes, starting and other links, and the speed is consistent with the national standard.

"Its shape is indeed not much different from ordinary electric vehicles. Many people think that they are ordinary lithium batteries or lead -acid battery electric vehicles." Zhang Bao, director of the Hydent Energy Division of the Institute, told reporters. "But hydrogen energy motorcycle There are only two mineral water bottles in the battery. Whether it is weight or volume, it is much lighter than lithium batteries or lead -acid batteries. "

Seeing that the reporter was suspicious, Zhang Bao opened the motorcycle seat and revealed two small metal bottles, which filled with alloy powder. "There are 110 grams of hydrogen reserved in these two small cans, which can be used for bicycles for 120 kilometers. After the hydrogen is used, it is necessary to replace the hydrogen tank."

Hydrogen energy is leading to a new round of "revolution"

In addition to the small weight and light weight, what are the benefits of using hydrogen energy batteries to replace lithium batteries or lead -acid batteries? Zhou Shaoxiong, general manager of the Research Institute Co., Ltd., introduced that hydrogen is easy to make, and in the process of preparation and conversion, the source is water, and the discharged products are also water. Essence In the universe, whether it is the sun or other stars to glow and heat, it must be supported by hydrogen through the energy generated by nuclear fusion.

At the same time, the solid -state hydrogen storage tank used by hydrogen energy batteries, the metal alloy materials used in are very environmentally friendly and easy to recycle. Because its raw materials are titanium, magnesium, iron, nickel and other elements, it can be 100 % recovered and melted, which will not cause pollution to the environment. "If the electrolyte of lithium batteries is not handled properly, it is easy to cause environmental pollution." Yuan Jianguang, deputy director of the Hydrological R & D Center of Research Institute Co., Ltd., told reporters.

Driven by the "double carbon" target, hydrogen energy is triggering a new round of energy revolution. At present, my country is the largest hydrogen -making country in the world, with an annual hydrogen production output of about 33 million tons, of which about 12 million tons reached the quality standard of industrial hydrogen gas. There is huge potential. The International Hydrogen Energy Commission predicts that global hydrogen energy will reach US $ 2.5 trillion (about 16 trillion yuan) by 2050, accounting for 18%of global energy consumption.

Can hydrogen vehicles replace electric vehicles

It is understood that the solid car hydrogen storage system has been successfully used in fuel cell buses. It does not require high -pressure hydrogenation stations. It can be fully fulfilled in about 15 minutes, and the vehicle can operate 15,000 kilometers. In the field of heavy trucks, this year, my country has developed a 4.5 -ton solid -state hydrogen storage fuel cell refrigerator. As a spare power supply for communication base stations, it can continue to run for more than 16 hours.

In the field of new energy vehicles, electric vehicles can be seen in the streets and alleys, but there are not many cars using hydrogen as fuel. Why can't solid -state hydrogen storage technology still be applied to new energy vehicles on a large scale? The original Jianguang told reporters that an important reason is that when solid hydrogen storage is released, a certain heat is required when the hydrogen is released, and the temperature must reach 250 ° C. This high -temperature environment has become a bottleneck restricting the development of solid hydrogen storage technology. Therefore, Chinese researchers are trying to add catalysts to reduce the environmental temperature required for hydrogen can release.

In addition, the hydrogen fuel electric pile power generation system equipped with solid hydrogen storage technology, the film electrode material used is now mainly imported, the cost is high. However, the reporter learned in the interview that domestic enterprises have produced film electrode materials that can replace foreign products, so the reduction of cost is only a matter of time. The reporter noticed that on March 23 this year, my country issued the "Long -term Plan for the Development of the Hydrogen Energy Industry", which is for the first time that hydrogen energy is an important part of the future national energy system. Hydrogen energy, as a rich, green and low -carbon, widely used secondary energy, is of great significance for achieving carbon peaks and carbon neutrality.

Wei Suo, President of the Hydrogen Energy Branch of the China Industry Development Promotion Association, said that the use of hydrogen energy is very wide: fuel can replace fuel and achieve clean transportation; it can be used as fuel raw materials and additives to replace coal and oil; Synthetic methanol and metal smelting.

It is reported that there are more than 300 industrial enterprises in the entire industry chain of hydrogen fuel cell vehicles in my country, which are concentrated in the Yangtze River Delta, the Guangdong -Hong Kong -Macao Greater Bay Area, Beijing -Tianjin -Hebei and other areas. In the future, solid hydrogen storage tanks are likely to become products like ordinary dry batteries, which can be purchased everywhere in convenience stores or supermarkets. Place the use of hydrogen energy bottle to the specified storage box, and the staff replace the new hydrogen energy bottle every day.

During the interview, the reporter also learned that with the breakthrough and localization of hydrogen -energy fuel battery technology, hydrogen energy will be industrialized in the fields of cars, ships, rail transits, garbage transport vehicles, heavy trucks, motorcycles, bicycles, etc. Thousands of households.
