According to foreign media reports, at the BAUMA 2022 exhibition site, Hyundai Construction Equipment first demonstrated the company's first hydrogen fuel cell power wheel excavator for the first time. ) Technology in developing hydrogen power electric vehicles and heavy trucks.
The HW155h concept car is equipped with a hydrogen fuel battery -driven power transmission system, which realizes zero -exhaust emissions.
The fuel cell installed in the back of the upper part of the machine, and the chemical reactions between the stored hydrogen and the oxygen existing in the air generate electrical energy. Then, it converts this energy into available power to drive the hydraulic pump to provide power for the device.
The hydrogen storage is in the right side of the machine and opposite the cab. Water is the only discharge released by fuel cells.
Modern construction equipment has been developing this technology since 2020. At that time, it signed a memorandum of understanding with Hyundai Motors and Hyundai Mobis at MABUK Research Center, which is located in Longren City, Gyeonggi -do. These three companies are cooperating with the development of hydrogen fuel cells to provide motivation for forklifts and medium and large excavators. Hyundai Motors has previously listed 2023 as the target period for large -scale production and sales.
This technology has been used in the NEXO hydrogen fuel cell vehicle of modern cars. Hyundai cars said that the car uses the second -generation fuel cell of modern cars, which is smaller, lighter and stronger than the original fuel cells in modern IX35 hydrogen fuel cell vehicles.
NEXO consumes 2 pounds of hydrogen at 62 miles, with a range of 413 miles. According to data from replacement fuel data centers, the energy of 2.2 pounds of hydrogen is roughly the same as the energy of 1 gallon gasoline. Like fuel, it takes only a few minutes to add hydrogen. It takes a few hours to charge for a few hours like a battery electric vehicle.
Modern companies said that this technology will be transplanted to engineering machinery and equipment, enabling the company to provide customers with the power and performance required by customers, and achieve zero discharge on -site. When using renewable energy (such as offshore wind energy) to produce hydrogen, it creates a very low -carbon power system.
Gert Peeters, the product manager of modern construction machinery European company, said: "Because of our efforts to achieve a carbon -free world, the development of the first hydrogen power excavator is very exciting. In the next few months, modern engineering machinery It will continue to develop and further improve this technology to achieve our goal of leading the future transition of zero carbon. Although the electric vehicle technology has made great progress, we may still ignore that hydrogen as a way to reduce carbon emissions and improve air quality It is a very practical solution.
"Our predictions show that future fuel power vehicles will be more cost -effective than battery electric vehicles or diesel power vehicles. Modern engineering machinery firmly believes that from the long run, hydrogen will be at the forefront of renewable energy. And use it in a solution for practice. "
