The Beijing 2022 Winter Olympics came to an end recently, and a new energy application news attracted attention: during the Winter Olympics, the organizing committee invested more than 700 hydrogen fuel buses in Yanqing and Zhangjiakou to provide transportation service guarantee.
This is an epitome of the increasingly wide application of hydrogen energy. In recent years, China has made breakthroughs in core technologies such as hydrogen fuel cell membrane electrode, and the layout of the whole hydrogen energy industry chain has become increasingly clear. With the gradual realization of hydrogen fuel cell from 0 to 1 in the automotive field, the construction machinery industry, which also takes internal combustion engine products as the main driving force, is also bound to usher in a dynamic change. What changes will this "whirlwind" of hydrogen energy bring to society? What is the development potential?
Trillion hydrogen energy tuyere attack
In the context of carbon neutralization, hydrogen energy has become an important solution for many countries in the world to achieve the goal of decarbonization and a key puzzle to solve the climate problem.
According to the white paper 2020 on China's hydrogen energy and fuel cell industry, at present, China's hydrogen production capacity is about 41 million tons per year and the output is about 33.42 million tons. It is the first hydrogen producing country in the world.
According to the blue book on infrastructure development of China's hydrogen energy industry, by 2030, the number of fuel cell vehicles in China will reach 2 million, and the industrial output value will exceed trillion yuan. Under the tide of "hydrogen heat", China's hydrogen energy and fuel cell industry cluster has been formed, the layout of the whole industrial chain is taking shape, and the industry is rapidly driving into the "fast lane".
Industry insiders generally believe that hydrogen, as an important industrial raw material and clean fuel, will form a competitive pattern in the coming decades. Fatih Birol, director of the International Energy Agency (IEA), said that at present, the global crude oil economy is experiencing a sharp shock, and "green hydrogen", as an emerging field of energy conservation and emission reduction targets, is becoming the focus of the industry. Now, many countries in the world have begun to explore green hydrogen, and China has also carried out 12 wind power hydrogen production projects and 7 photovoltaic hydrogen production projects. "Clean hydrogen" has also been set as a "priority development area" in the "green agreement" drawn up by the EU some time ago.
From the perspective of environment and ecology, hydrogen production from renewable energy such as wind power and photovoltaic can not only achieve "zero carbon emission" and obtain truly clean "green hydrogen", but also convert and store intermittent and unstable renewable energy into chemical energy and promote the digestion of new energy power. The resulting eco-environmental and economic benefits are immeasurable.
Accelerated layout in the field of construction machinery
Construction machinery is a famous "oil tiger". Under the dual wheel drive of national energy transformation and upgrading and environmental protection, accelerating the energy conservation and emission reduction of construction machinery has become the goal and task of the industry. Hydrogen fuel cell has the advantages of zero emission and zero pollution, and can adapt to high-intensity continuous operation. It is considered to be one of the most promising alternative power solutions.
In recent years, many enterprises have begun to try to apply hydrogen fuel cells to engineering machinery. Hydrogen forklifts, tower cranes, excavators, snow beauty machines and other equipment have been successfully applied.
In November 2020, XCMG released the first hydrogen fuel cell muck truck on Bauma China, which is equipped with Hongtu G110 fuel cell engine provided by Guohong hydrogen energy; In December, Zoomlion released the world's first hydrogen fuel sanitation dust suppression vehicle, which is equipped with a fuel cell system with a rated power of 63kw, provided by Hubei Haiyi; In the same month, Sany Heavy Industry hydrogen fuel cell engineering vehicle and the world's first hydrogen fuel cell mixer went offline. The vehicle is equipped with reshaping technology PRISMA Jingxing 110KW fuel cell system.
At the same time, many domestic and foreign enterprises have arranged hydrogen fuel heavy trucks. Overseas, American Nikolay, Japanese Toyota, Korean Hyundai and other auto enterprises have launched hydrogen fuel heavy trucks; In the domestic market, Jiefang, Dongfeng, Hongyan, Shaanxi Automobile, Jiangling, Universiade and other automobile enterprises have also developed relevant products.
The change of policy wind direction and the certain advantages of hydrogen fuel cell itself are the biggest motivation for enterprises to carry out layout in the field of hydrogen fuel cell engineering machinery. In addition, as a "means of production", the operating cost of hydrogen fuel cell is even lower than that of pure electric loading vehicle. This also makes hydrogen fuel cell expected to become one of the directions of power transformation in the field of construction machinery.
At present, passenger cars have not yet realized hydrogen energy on a large scale, but the field of construction machinery has long been hot. Not only in hydrogen energy, but also in the degree of automation, construction machinery is once again leading!
Unmanned construction machinery has realized overtaking at curve
Driverless driving has always been a hot topic, and it is no exception in the field of construction machinery. In recent years, with the acceleration of large-scale infrastructure construction, the requirements for equipment construction efficiency and mobility are higher and higher. Coupled with the popularization and application of intelligent, digital and 5g technology, domestic mainstream construction machinery manufacturers have launched driverless products and technologies, and some equipment have appeared on the construction site.
Trinity: realize unmanned driving in multiple scenes and all working conditions
On February 6, Sany ocean heavy industry's new driverless pure electric tractor sm4254tobev officially went offline, taking a new step in the R & D and manufacturing of logistics equipment in smart port. In addition to the pure electric port tractor delivered this time, Sany has also successively launched a series of intelligent equipment such as driverless wide body vehicle, excavator, paver and mixer.
Driverless excavator is an earlier driverless field developed in the construction machinery industry. Mining dump truck is the earliest field of driverless research and development and put into use. Sany driverless technology is involved in these fields. As early as 2018, Sany established a wholly-owned subsidiary Sany smart Mining Technology Co., Ltd. in Beijing, and launched the first generation of driverless pure electric wide body dump truck in 2019, which is only the tip of the iceberg of Sany driverless and intelligent industry.
From the initial remote control to driverless, and then to the remote control of driverless combined unit operation, Sany group has made a comprehensive layout in terms of intelligence, new energy, fuel cell and driverless, focusing on technology R & D and innovation in many fields, and gradually put it into application.
Zoomlion: Science and technology enables modern agriculture
On February 7, Zoomlion plans to acquire Luchang technology for 780 million yuan. The company is involved in the research and development of driverless solutions and intelligent travel solutions, which will greatly help Zoomlion's intelligent and driverless research and development.
In recent years, Zoomlion has taken building high-tech industry as the main line, enabled modern agriculture with science and technology, strengthened scientific and technological innovation in the intellectualization of agricultural machinery, and successively launched driverless seedling throwing machines and driverless combine harvesters. These intelligent products have achieved "self diagnosis, self adjustment and self adaptation", which can improve the harvest quality and yield of crops and greatly improve agricultural productivity.
In addition, Zoomlion also launched artificial intelligence products such as driverless sanitation vehicles and road sweepers to help the sanitation industry become intelligent and save environmental sanitation labor costs.
XCMG: unmanned cluster construction technology realizes normal construction
XCMG's unmanned cluster construction technology has successfully carried out normal construction in 12 provinces. In recent years, one belt, one road and the other is the construction of hydropower projects. The construction efficiency is increasing and the cost of labor is rising. It is also the reason for all industries to improve their construction efficiency and reduce their labor cost through technical means.
Since 2018, XCMG's unmanned cluster technology has been popularized and applied in major projects such as Shanghai Nanjing Expressway, Xinjiang a Wu Expressway and Beijing Xiong expressway, and the construction quality, efficiency and safety have been greatly improved. A series of driverless intelligent equipment such as XCMG double cylinder roller and large width paver participating in the construction can be controlled within 2cm based on Beidou high-precision positioning, inertial navigation and radar multi-sensor fusion technology, which can not only improve the construction efficiency, but also effectively ensure the construction quality.
Liu Gong: intelligent one-stop production product service
At last year's "11.26" global customer Festival, Liugong took the lead in releasing three intelligent equipment: driverless excavator, driverless loader and driverless roller. It is an driverless equipment developed and manufactured by Liugong for typical working conditions. It adopts the insight system and intelligent control system developed by completely independent innovation, and has the functions of environmental perception, path planning, active obstacle avoidance and independent operation, It is convenient for users to apply driverless equipment to more different working conditions.
Liugong intellectualization mainly covers three aspects: intellectualization of production line; Intellectualization of products; The intellectualization of post market services, as the forerunner of mastering a full set of 5g intelligent remote control technology from mechanical equipment, control system to communication integration, Liugong launched three unmanned equipment, key parts "lighthouse factory" and big data platform monitoring equipment operation, which shows that the enterprise's unmanned remote control operation technology has been integrated with the Internet of construction machinery and continues to move to high-end, intelligent Transformation and upgrading in the direction of green development.
Driverless technology in smart mine
The above-mentioned enterprises have different priorities in the research and development of driverless technology, but there is also a common field, that is, the introduction of a series of equipment such as mining machinery, driverless dump truck, excavator and loader, which has driven the development of energy conservation, environmental protection, intelligence and unmanned mining machinery.
In the field of construction machinery, mining machinery has always played an important role. With the continuous advancement of China's smart mine construction, the transformation from mine automation to digital mine and then to smart mine has been realized. Many enterprises have relatively mature R & D and technical application in mining machinery. Although mine driverless technology started late, it has a strong advantage of late development, and has realized curve overtaking on the track of mine intelligent transformation and upgrading.
