original title: towards "hydrogen"! how will hydrogen energy enter our lives? let's find out together →
today we are focusing on a clean energy source, hydrogen.
in order to reduce carbon emissions, many factories are now using hydrogen as an alternative energy source, and some hydrogen-powered vehicles are also being put into use. my country has also made the development of hydrogen energy a focus of future clean energy.
not long ago, the longest hydrogen corridor in my country was officially put into use. it runs from beijing to shanghai, across five provinces and cities, with a total length of more than 1,200 kilometers. recently, cctv reporters also took a hydrogen truck from beijing and experienced the hydrogen truck and hydrogen highway throughout the journey.
unveiling the secrets of hydrogen-powered heavy trucks
what discoveries have been made along the way? what is the difference between a hydrogen truck and a regular truck? what is different about the hydrogen corridor?
cctv reporter zhang congjing: the biggest difference of this hydrogen heavy-duty truck is that there is a big box between the front of the truck and the cargo box, which is filled with hydrogen fuel.
cctv reporter zhang congjing: while this car is refueling, let's take a look at this hydrogen heavy truck. if it is an ordinary fuel vehicle, it will emit exhaust gas. but it actually emits water vapor here. let's look at a more intuitive one. there is also a drain in this part of the car, and water is dripping down now. as you can see, the cup in my hand is the product produced by the power generation of this hydrogen heavy truck. it looks colorless and transparent, very pure, and has no smell. this is actually a cup of pure water. this shows very intuitively that hydrogen heavy trucks are very environmentally friendly, clean, and pollution-free. the interior of this hydrogen heavy truck may not look much different from that of an ordinary truck, but the feeling of sitting in it is still very different. this position in the cab is actually the engine. because there is no fuel engine, there is no noise or oil smoke when the whole car is driven.
the latest data shows that in the first seven months of this year, sales of hydrogen fuel cell vehicles were 3,422 units, an increase of 25.5% year-on-year.
visit the hydrogen highway
in addition to large trucks like this one, hydrogen energy is also used in cars, buses, sanitation trucks, logistics trucks, etc. that are common in daily life. as the number of models increases and the number of application scenarios increases, how do these vehicles perform after they are on the road?
early in the morning, the reporter arrived at the beijing daxing angu hydrogen refueling station, which was already full of cars.
wang yi, an employee of sinopec angu hydrogen refueling station: the main thing is to eliminate static electricity in the hydrogen refueling vehicle first, and then the human body must also release static electricity. because we are using hydrogen, which is a compressed gas, the gun is heavy. the hydrogen detector detects whether there is a hydrogen leak, and then we turn on the machine to start it.
the staff told reporters that a large truck like this can be filled with nearly 60 kilograms of hydrogen in about 20 minutes. this amount of hydrogen costs about 2,000 yuan and can run more than 600 kilometers.
at the scene, reporters saw that, like oil storage tanks, the station also had large tanks for storing hydrogen. staff told reporters that these large tanks can fill dozens of vehicles with hydrogen every day.
along the way, the reporter saw many hydrogen trucks and hydrogen cold chain logistics vehicles. there are nearly 20 hydrogen refueling stations built on this hydrogen highway.
the hydrogen energy industry chain is accelerating its development
at present, most of the hydrogen used to fill vehicles is produced by industrial production. so what is the current development status of the hydrogen energy industry chain?
the reporter first came to yanshan petrochemical, which produces hydrogen. as soon as he entered the hydrogen supply center, he saw a huge facility full of storage tanks and pipes.
li junliang, chief expert of yanshan petrochemical: hydrogen mainly comes from industrial byproducts, which are byproducts of gasoline and diesel produced by refineries. to transport the hydrogen we produce, we have to use this long-tube trailer to transport it outside. it is equivalent to putting two swimming pools of hydrogen in this truck under strong pressure.
the key to hydrogen storage lies in the storage tank. the reporter saw that the staff at a hydrogen storage bottle manufacturer in jiangsu were using carbon fiber winding to make high-strength hydrogen storage bottles.
ding leizhe, executive vice president of jiangsu guofu hydrogen energy technology equipment co., ltd.: this is one of our core processes, carbon fiber winding. you can see the carbon filaments at the back joint, like a loom, weaving up layer by layer. carbon fiber is mainly used to bear pressure.
technicians told reporters that the liquid hydrogen storage and transportation technology they developed has also made new progress.
wang kai, general manager of jiangsu guofu hydrogen energy technology equipment co., ltd.: this is a liquid hydrogen storage bottle developed by our company. its hydrogen storage mass density is three times that of the conventional type iii bottle with a 35 mpa rating, which is very helpful for the vehicle's cruising range.
shandong was the first province in china to allow hydrogen-powered vehicles to travel on highways for free. the reporter learned here that shandong province has organized more than 30 hydrogen energy industry advantaged enterprises and universities and research institutes to carry out technical research in the four cities of jinan, qingdao, zibo and weifang, and the resource concentration development pattern of the hydrogen energy industry is becoming increasingly effective.
han shaohua, director of the major project office of the shandong provincial department of science and technology: from key materials and key components to complete vehicle equipment, nearly 200 companies in the core chain of the hydrogen energy industry chain have driven more than 1,000 related supporting companies. hydrogen energy communities, parks, ports, and docks are basically complete.
according to the "medium- and long-term plan for the development of the hydrogen energy industry (2021-2035)", by 2025, china will have basically mastered the core technology and manufacturing process of hydrogen energy, and the number of hydrogen fuel cell vehicles is expected to reach about 50,000, and a number of hydrogen refueling stations will be deployed and built. in addition, the amount of hydrogen produced by renewable energy will reach 100,000 to 200,000 tons/year, and it is expected to achieve a carbon dioxide emission reduction of 1 million to 2 million tons/year.
accelerating deployment in various regions
expanding hydrogen energy application scenarios
during the investigation, the reporter learned that in recent times, many places have introduced policies to support the hydrogen energy industry to accelerate the development of the hydrogen energy industry. my country has made progress in many aspects such as hydrogen energy preparation, storage and transportation, and infrastructure construction, and the development potential of the hydrogen energy industry is gradually being released.
at a hydrogen heavy-duty truck fuel cell system manufacturer in shanghai, the person in charge told reporters that they are the first company in china to mass-produce fuel cell systems equipped with domestically produced proton exchange membranes. proton exchange membranes are core components of hydrogen fuel cells and have long relied on imports.
liu yisu, director of strategy marketing department of reshape energy: this is the most critical material, so we use domestic proton exchange membranes in large quantities so that more people can enjoy the application of hydrogen energy technology. in addition, as a key technology, we can avoid dependence on the supply chain and achieve domestic independence.
at present, hydrogen heavy trucks equipped with domestic proton exchange membrane fuel cells can travel more than one million kilometers in their entire life cycle. in sichuan, the first large-scale commercial water electrolysis hydrogen production project in the southwest region was officially put into commercial operation a few days ago, with an annual hydrogen output of 1,860 tons. in shaanxi, the first fully automatic production line for hydrogen fuel cell stacks in the northwest is stepping up production of the first batch of orders this year. the hydrogen energy industry in the three major regions of the yangtze river delta, the guangdong-hong kong-macao greater bay area, and the bohai rim is showing a clustered development trend.
by the end of 2023, my country has built and operated 428 hydrogen refueling stations, and has built 58 renewable energy hydrogen production projects covering 21 provinces, autonomous regions and municipalities. it is predicted that by 2060, my country's hydrogen energy consumption will reach nearly 86 million tons and the industry scale will reach 4.6 trillion yuan.
