Trucks reduce pollution and carbon, and China presses the fast forward button?

During the "Fourteenth Five-Year Plan" period, we should continue to dig deep into the potential of reducing pollution and carbon in the truck industry and enhance the green competitiveness of trucks.

The heavy truck charging station on Hu Lin Road in the western suburb of Zhengzhou is open to the public, and more than ten heavy trucks are charging.

Transportation industry is the key field of pollution reduction, carbon reduction and synergy in China. Among them, trucks with small volume and high emissions cannot be ignored. It is understood that trucks only account for 1 1% of the car ownership, but their emissions of carbon dioxide, nitrogen oxides and particulate matter account for more than 50%, 80% and 90% of the total car emissions respectively. How to reduce the road freight emission of trucks has become the key to achieve the goal of "double carbon" in China's freight industry and even the transportation industry.

"2023 China Green Freight Pioneer" Forum was held in Beijing. The latest report "Research on the Progress of Reducing Pollution and Carbon in China Truck Green Card List" jointly released by Asian Clean Air Center, Tsinghua University Environmental Research Institute and National Big Data Alliance for New Energy Vehicles points out that China's diesel vehicle pollution control battle has achieved phased results, diesel vehicle pollutant emissions have continued to decline, and new energy trucks have entered the fast lane. During the "Fourteenth Five-Year Plan" period, we should continue to dig deep into the potential of reducing pollution and carbon in the truck industry and enhance the green competitiveness of trucks.

Diesel vehicle emission reduction effect appears

The director of the transportation project of the Asian Clean Air Center said: China has gradually promoted the emission reduction of freight trucks by upgrading the standards of new cars. During the' Thirteenth Five-Year Plan' period, the pollution reduction and carbon reduction of trucks ushered in a key development node, and the Ministry of Ecology and Environment and other 1 1 departments jointly issued the Action Plan to Combat Diesel Truck Pollution. With the support and guidance of this plan, China's truck pollution reduction and carbon reduction work has achieved phased results. "

The report shows that diesel trucks are still the main force of new truck sales, accounting for more than 90%. The number of trucks in China increased by 20%, while the emissions of nitrogen oxides and particulate matter decreased by 7.5% and 6.5% respectively. The emission level of diesel trucks is obviously reduced.

The upgrading of fuel consumption standards continues to reduce the fuel consumption level of new cars, and the strengthening of emission supervision and the improvement of emission supervision system have played an important role in reducing pollution and carbon of diesel vehicles. "Thanks to the upgrade of new car standards, especially the implementation of the national six standards, the emission reduction effect of diesel vehicles is more significant than before. The annual inspection and on-board inspection data show that the emission concentration of nitrogen oxides of the National Sixth Vehicle is 56%-73% lower than that of the National Fifth Vehicle, and the emission reduction advantage is obvious. "

Professor Tsinghua University Institute of Environment gave accurate data. "After three years of action, the emission of nitrogen oxides from diesel vehicles in China decreased by 14% and the emission of fine particles decreased by 23%."

The chief engineer of the Institute of Environmental Resources of the Environmental Planning Research Institute of the Ministry of Transport pointed out that the adjustment of transportation structure is also one of the main measures in the first phase of diesel vehicles. The Ministry of Transport makes full use of vehicle purchase tax funds to support the adjustment of transportation structure. The national railway freight volume increased to 4.9 billion tons, an increase of nearly 50% compared with 20 16. The proportion of railway freight volume has increased by three percentage points, and the adjustment of transportation structure has achieved remarkable results. "

New energy trucks become weather vanes.

On the one hand, it promotes the transformation by reducing the emission and use of diesel trucks, on the other hand, it accelerates the electrification process of trucks and sets a new trend for the development of trucks. "While effective progress has been made in diesel vehicle emission reduction, the new energy truck market is booming. Entering the' 14 th Five-Year Plan', the development of new energy trucks presses the acceleration button. "

The Executive Secretary of the National New Energy Vehicle Big Data Alliance said that in 2022, the sales volume of new energy trucks in China reached1720,000, an increase of about 4.6 times compared with the end of the Thirteenth Five-Year Plan. Among them, the sales of pure electric trucks and hydrogen fuel cell trucks reached168,000 and 30.74 million respectively, which were about 4.5 times and 37.9 times higher than those at the end of the 13th Five-Year Plan.

The report points out that the electrification of trucks in China presents three characteristics. First, the number of cities that promote the electrification of trucks continues to increase, and second-and third-tier cities have entered the fast lane, and fourth-and fifth-tier cities have also begun to become important positions for promotion; Second, the number of enterprises deploying new energy trucks is growing rapidly, and the products are blooming, and the competition is becoming increasingly fierce; Third, the application scenarios of new energy trucks are constantly expanding, and the models are diverse, covering different configurations.

Behind the rapid development of new energy trucks are favorable policies and rapid upgrading of technology. "Take the new energy heavy truck as an example. From 2020 to 2022, the sales volume of new energy heavy trucks increased by 7.7 times, and the penetration rate increased from 0.2% to 7.8%. In 20021year, the Ministry of Industry and Information Technology started the pilot application of the new energy vehicle power exchange mode, and the publication of the Medium and Long-term Plan for the Development of Hydrogen Energy Industry (20021-2035) promoted the development of power exchange technology and hydrogen fuel cell technology, and promoted the breakthrough of self-exchange heavy trucks and hydrogen fuel cell heavy trucks. "

It also affirmed the positive role of the policy in promoting new energy trucks. "Up to now, the Ministry of Transport has released three batches of green freight distribution demonstration projects to create a list of cities, and 77 cities have been selected, and the number and proportion of new energy logistics vehicles have increased significantly."

Expect a technological breakthrough

In June, 2022, 1 1, the Ministry of Ecology and Environment and other 15 departments jointly issued the Action Plan for Pollution Control of Diesel Freight Cars, which clearly stated that by 2025, the clean and low-carbon degree of transportation structure and vehicle and boat structure will be significantly improved, and the fuel quality will continue to improve. The qualified rate of diesel vehicle emission testing in China will exceed 90%, and the emission of nitrogen oxides from diesel vehicles in China will be reduced by 12.

"In the previous emission control system, the action plan set a clearer emission reduction target. In the process of zero-emission cleaning, the freight industry still needs to accelerate its transformation. " At present, it is in a period of connecting the preceding with the following. How to continue to dig deep into the potential of pollution reduction and carbon reduction in the truck industry, broaden the use scenarios of new energy vehicles and enhance green competitiveness are the key issues to be considered in the next stage. "

Liu, deputy director of the Green and Low Carbon Department of the Standard Institute of China Automotive Technology and Research Center, believes that technological upgrading is an important way to reduce the carbon content of trucks, and the fuel consumption of commercial vehicles at the technical level still has the potential to reduce 12%- 15%. However, in order to reduce the consumption of trucks in the future, it is necessary to do a good job in internal resource planning and cooperate with multi-departments to innovate. In addition, for different application scenarios and models of trucks, systematic consideration and targeted analysis are needed.

The report pointed out that the truck industry needs to make continuous breakthroughs in exhaust emission control technology, energy-saving technology and new energy technology. The strengthening of relevant environmental protection standards will help to promote technology research and development, industrial promotion and application, and promote the development of truck industry to ultra-low emission and zero emission. Especially in the field of new energy trucks, the level of new energy trucks is still relatively low, and there is great room for development in terms of market scale, utilization rate, use intensity and scene adaptability. Enterprises can focus on battery energy density, energy saving and energy supplement technology to enhance users' recognition of new energy trucks.
