Under the background of realizing the goal of "double carbon" and building a new development pattern of double cycle, electrification has become one of the important directions for the green development of construction machinery, including the electrification of overweight layout equipment of domestic construction machinery leaders such as Zoomlion (000157. SZ) and the launch of a variety of electrification products.
Some organizations predict that the pure electric construction machinery market will reach the breaking point in 2025, and the penetration rate of main products may reach 25%. Fu Ling, vice president and chief engineer of Zoomlion, told reporters that "by 2025, the company will realize a full range of new energy products, reduce carbon emissions during product use by 25% compared with 2020, reduce product energy consumption by 20% compared with 2020, and realize 100% green chemical plant. During the 14th Five Year Plan period, the proportion of motorized products will increase year by year".
Construction machinery electrification "blue ocean" market
In 2020, the Ministry of industry and information technology issued the action plan for promoting the electrification of vehicles in the public domain to promote the electrification of construction machinery and accelerate the transformation of construction machinery industry to new energy.
The iron and steel industry is not only a large energy consumer, but also a large carbon emitter. There is great pressure on emission reduction. The use of electric construction machinery is an important measure to reduce carbon emissions. Fu Ling, for example, said that the journey of engineering machinery following a steel plate, starting from the steel plate entering the processing and manufacturing link, has to go through multiple links such as blanking - Welding - processing - Coating - assembly - commissioning, which has become a mechanical product entering the market for 10 years, with a total carbon emission of about 1220 tons. In the manufacturing phase, carbon emissions accounted for only 1.8%, and in the 10-year use phase accounted for 95.5%.
In this regard, the green development strategy proposed by Zoomlion is to realize the greening of the whole product life cycle. In terms of green design, focus on new energy, new materials and new methods to realize low-carbon, low emission, high efficiency, energy saving and safety of products. The goal of the 14th five year plan is to reduce the comprehensive carbon emission of a single product by 25%.
"In terms of new energy, the company has successfully developed hybrid excavator in 2009 and launched new energy engineering machinery of the whole product line in 2021. For 2025, we have set an ambitious goal for green design. Taking concrete pump truck as an example, if we design future products integrating green technologies such as new energy + new materials, compared with fuel pump truck, the energy consumption cost will be reduced by 50% and the carbon emission will be reduced by 60 tons/ "For the annual platform, the use cost is saved by 250000 / year," Fu Ling said.
Hunan is the largest manufacturing base of construction machinery industry in China. On November 26, Zoomlion unveiled 16 new energy products in 8 series, and released the industry's first domestic carbon fiber boom pump truck. New energy products cover cranes, pump trucks, mixer trucks, aerial work platforms, emergency equipment, excavation machinery, mining machines, heavy chassis, etc; Compared with the high-strength steel boom, the lightweight carbon fiber boom is 35% lighter and the weight of the whole machine is reduced by 3 tons.
The relevant executives of the company calculated an account for the reporter. Customers are still concerned about the oil price. From the perspective of the 7.5-ton pure electric excavator currently launched by the company, on the one hand, it hardly needs to be maintained like a diesel excavator in the whole life cycle, and the maintenance cost will be greatly reduced; On the other hand, from the perspective of activity-based cost, electricity consumption only costs 15-20 yuan per hour, while the cost of using diesel is 35-40 yuan. It is expected that the replacement demand of mechanical equipment such as pure electric small excavators will be relatively fast in the future.
In 2025, the penetration rate of main products will be 25%
Facing the goal of "reaching the peak of carbon", major construction machinery enterprises such as Sany Heavy Industry, Zoomlion and XCMG have arranged new energy products one after another. In the product structure, excavators, loaders and cranes are the top three products in sales. There is a large demand for lithium batteries in the penetration of motorized products. Zoomlion is committed to independent research and development breakthroughs in system integration technology. Supporting domestic products such as batteries and motors have cooperated with major battery manufacturers including Ningde times.
During the two sessions last year, Zeng Yuqun, member of the National Committee of the Chinese people's Political Consultative Conference and chairman of Ningde times, submitted the proposal to fully promote the electrification of vehicles in public service fields such as construction machinery and heavy trucks, win the blue sky defense war and form a global industrial highland, focusing on accelerating the promotion of electrification of construction machinery and heavy trucks.
It is worth mentioning that the current electric construction machinery products are still in the initial stage. Unlike new energy passenger vehicles, there is still much room for improvement in policy support. Industry insiders appeal that construction machinery is a large fuel consumer, and also hope that relevant policies will be issued to support the development of new energy vehicles for construction machinery.
Brokerage institutions believe that from the perspective of technical path, the electrification of construction machinery first uses electric drive to replace conventional diesel engine drive, and then hydraulic actuator is replaced by electric actuator. Concrete mixer, muck truck, excavator and loader are the most easily motorized products in the future, especially small construction machinery.
It is expected that major construction machinery manufacturers will launch their main motorized products in 2023, and 2025 will usher in the first peak sales of motorized products. It is estimated that by 2025, the total sales volume of electric products for four types of engineering vehicles: concrete mixer, muck truck, excavator and loader will be 120000, with a penetration rate of 25%.
