Scientists of the Moscow Physics and Technology institute have developed an innovative concept for environmentally friendly transport for quarries. They presented a detailed design of a powerful hydrogen fuel cell dump truck and a special refueling station for it. This development could revolutionize the mining industry.
The engineers took as a basis the well-known model of the mining giant – BelAZ-75306. The key change is the complete abandonment of the diesel engine. A modern hybrid system will take its place. It is based on hydrogen fuel cells, which are complemented by lithium-ion batteries and a supercapacitor. The total capacity of such a power plant will be a record 1 MW.
The new power plant will also require a modern transmission. The machine will be equipped with an electromechanical system that provides smooth and flexible power control. This will not only increase driver control over the truck, but will also significantly reduce wear on key components, reducing the frequency of costly repairs.
To refuel equipment, scientists have proposed two “green” methods for producing hydrogen: through electrolysis of water or by capturing and processing by-product gases at metallurgical plants. The compressed gas will be stored in a purpose-built hydrogen filling station.
The main advantages of switching to hydrogen are a dramatic reduction in harmful emissions and improvement working conditions for drivers. In addition, economic efficiency will also increase: more powerful and reliable vehicles will be able to transport more cargo, which will reduce the fleet without losing overall performance.
It is expected that the first tests of the prototype will begin within the next two years. According to calculations by MIPT specialists, the use of hydrogen fuel can increase the overall energy efficiency of quarry equipment by almost three times, while maintaining a zero emission level.
The material was prepared with the support of the Russian Ministry of Education and Science as part of the Decade of Science and Technology.
