"Complementation of hydrogen energy and electricity is an important part of the energy strategy, and the heavy truck of fuel cells is a breakthrough." On September 3, the 2022 Taiyuan Energy Low Carbon Development Forum "Hydrogen Energy Economic Development Forum" held in Shanxi. Lin Zhongqin, an academician of the Chinese Academy of Engineering and president of Shanghai Jiaotong University. He believes that promoting "hydrogenation Shanxi", fuel cell heavy trucks will be the first to be economical in the country.

In the keynote speech entitled "Double Carbon" strategy under the development of hydrogen energy and fuel cell vehicles, Lin Zhongqin said: At present, the total discharge of carbon dioxide in my country is 12.5 billion tons/year; it is expected to reach 13 billion tons/year by 2030; By 2060, it will not exceed 1.5 billion tons/year in the carbon neutralization. In the process of changing from 13 billion tons to 1.5 billion tons, economic and social development will face severe challenges.

He pointed out that carbon tax will seriously restrict my country's sustainable economic and social development. To achieve carbon peaks and carbon neutrality is a wide and profound energy system change. It is necessary to coordinate the development of fossil energy and renewable energy, and gradually realize low -carbon transformation of energy.

There are five major trends: new energy gradually moves from supplementary energy to main energy sources, fossil energy from main energy to guarantee energy energy, and then electrification is expected to become an important path of carbon neutrality. Renewal fuels and zero carbon power form an important combination. Towards the development of technological innovation.

He believes that the implementation of the "double carbon" strategy is inseparable from the complementary complementary of hydrogen energy and power, which is an important part of the energy strategy. By 2030, the demand for hydrogen in my country will exceed 37 million tons, accounting for about 5%of terminal energy consumption. In 2060 carbon neutralization, my country's hydrogen demand will reach 130 million tons, accounting for about 20%of terminal energy consumption.

The expansion of hydrogen can gradually advance from four links: hydrogen -making, storage and transportation, hydrogenation stations, and automobiles. Lin Zhongqin predicts that by 2030, the hydrogen -making method will develop from the current non -green, light green hydrogen production to the dark green hydrogen -making stage; the cost of storage and transportation will gradually decrease, the safety is steadily improved, and the hydrogen gas pipeline transportation technology, long distance high pressure Hydrogen pipeline technology is mature; in terms of hydrogenation stations, the national hydrogen energy supply and use of infrastructure grids are built; fuel cell vehicles will reach 2 million vehicles from demonstration operation to market -oriented operation.

Lin Zhongqin urged to accelerate the commercialization of fuel cell vehicles.

Data show that in 2021, my country's truck reserves 32.42 million vehicles, of which 8.5 million were heavy trucks, only 2.6%of the heavy trucks with a total amount of 47%of the carbon dioxide. Car.

At present, the demonstration areas such as Beijing, Shanghai, Guangdong, and non -demonstration areas such as Shanxi and Inner Mongolia are actively promoting fuel cell vehicles. A total of about 10,000 fuel cell vehicles have been promoted, and about 44%of commercial vehicles.

Lin Zhongqin believes that there are both technical factors and market factors that restrict the development of fuel cell vehicles in my country. The price of 49 tons of fuel cells in 2019 is about 1.8 million yuan/vehicle, and about 1.5 million yuan/vehicle in 2022. The purchase cost is still high. The cost of domestic hydrogen injection is also high. It is 2 to 3 times that of the same type of diesel heavy card, and the operating cost is high.

The weight card equipped with a 250kWh lithium battery is only 130 kilometers, and the heavy card battery life with a 240kW fuel cell system+hydrogen system can reach 700 kilometers. The middle and long -distance logistics routes such as ports, mining, and residue transportation are long and relatively fixed. The layout of the hydrogenation station is relatively easy, and the development of fuel cell heavy trucks is more advantageous.

Therefore, he suggested to accelerate the commercialization process of the heavy truck of fuel cells, adopt the national demonstration urban agglomeration subsidy model, and provide financial subsidies for vehicle purchase and hydrogen prices; the use of wind power photovoltaic resource subsidies to realize the pure hydrogen supplement and use low -cost hydrogen pure pure pure hydrogen, and use low -cost hydrogen pure pure pure hydrogen. Commercial models make up for the purchase fee with low cost.

Shanxi is the largest coking coal production base in the world. The reserves of coking coal reserves accounted for 60%of the country, and the potential for hydrogen production of industrial by -production was about 2.6 million tons/year. The hydrogen production capacity of renewable energy was 1.1 million tons, accounting for 9.25%of the country. Moreover, the five major industries of coal, coke, aluminum, smelting, and electricity in Shanxi can jointly drive the application scenarios of about 400,000 heavy trucks.

In this regard, Lin Zhongqin suggested that the Shanxi hydrogen energy industry should play the two cards of "the most advantageous hydrogen prices in the country" and "the largest heavy truck application base in the country" to gather national wisdom, introduce high -quality enterprises, and build a high -level "technical chain" And "Industrial Chain"; Give fuel cell heavy truck purchase subsidies, and control the hydrogen injects to 20 yuan/kg. By 2024, the cost of heavy cards of fuel cells can be the same as that of diesel vehicles. The heavy card will be the first to be economical in the country; give hydrogen energy encouragement+punishment measures, guide enterprises to consciously use hydrogen energy cards, promote "hydrogenation Shanxi", and build the country's largest hydrogen energy card application base.
