Organization Name:CHINESE INSTITUTE OF COAL SCIENCE

Project introduction:

Under the background of the national energy revolution and the realization of the double carbon target, the industry has put forward the development requirements of green low-carbon and intelligent coal mine in order to build a modern coal economic system. At present, the global mining equipment, especially the dump trucks used in large open-pit mines, all use diesel power system, which has great pollution and high fuel consumption. The electrification of large mining dump trucks has always been the direction of the industry efforts. Due to the practical needs of heavy load, bad working condition and long time operation of large mining trucks, pure electric mining dump trucks have disadvantages such as short driving range, long charging time, large battery size and heavy weight, which can not meet the use needs of large mining dump trucks. The project carried out research and development of hydrogen fuel cell mining dump trucks, and realized unmanned driving in the new models with hydrogen energy as the power architecture. The project carried out top-level planning for hydrogen fuel cell system and vehicle deployment, green hydrogen fuel supply chain and unmanned driving solutions. The team made key breakthroughs in technical difficulties such as high power of single storage, safety strategy, optimization of assembly system, energy distribution strategy, new hydrogen production and unmanned driving algorithm, established equipment manufacturing, fuel cell subsystems, green hydrogen production transportation supply refueling, unmanned driving system hardware and software industry lines, built a special hydrogen fuel power platform for coal mine and various software and hardware development platforms. The supporting metal bipolar plate fuel cell stack has the largest single power and the highest power density, and the combined power of hydrogen and lithium is the largest, so as to realize the largest hydrogen energy unmanned mining dump truck in China. It can establish the first set of green hydrogen supply chain for open-pit mining area, reform the existing refueling platform, and finally build a normalized hydrogen fuel cell unmanned dump truck production demonstration mining area, helping green hydrogen scale economy.
