Recently, State Grid Wenzhou Power Supply Company, in collaboration with Hydrogen Aviation Technology, deployed multiple models of hydrogen-electric drones in areas affected by Typhoon White Dolphin to carry out tasks such as power transmission line inspection, disaster image transmission, and emergency supply transportation, providing aerial support for post-disaster investigation and power repair in Yongjia, Yueqing, and other locations in Wenzhou, Zhejiang.
Affected by heavy rainfall, some mountainous areas experienced slope hazards, fallen trees, and road blockages, significantly increasing the difficulty of labour inspection and operational risks. To improve emergency response efficiency, both parties completed the scheduling of personnel, equipment, and support resources in advance, deploying hydrogen-electric drones to key areas such as Yongjia and Yueqing to assist on-site personnel in quickly grasping the status of power transmission lines and surrounding environments.
In this operation, two types of hydrogen-electric drones, the DJI Hydrogen Aviation M400 and FC100, were deployed, and a coordinated operation mode was formed based on different mission requirements. The relevant equipment had previously participated in flood relief in Guangxi and typhoon disaster emergency support in Huizhou, Guangdong, accumulating practical experience under complex weather and disaster conditions.
The DJI Hydrogen Aviation M400 primarily took on large-scale power transmission line inspection. Relying on the long endurance characteristics of the hydrogen power system, this model was able to conduct aerial inspections within a 40-kilometer radius under conditions of road blockages and higher risks in mountainous areas, and could complete line inspections spanning mountainous areas and continuously covering approximately 60 kilometers.
During the operation, the drones surveyed power transmission corridors that were difficult for engineering vehicles and inspection personnel to access, promptly transmitting back on-site images and line status data. The relevant information can provide a reference for power grid enterprises in assessing damage, locating faults, and formulating repair plans, while reducing the frequency of personnel entering high-risk areas.
The FC100 hydrogen-electric drone mainly took on emergency supply air transport. Facing road disruptions and mountain flooding, this model could transport repair materials, operational tools, and other emergency support supplies within a 20-kilometer radius, establishing a rapid aerial transport corridor for obstructed areas.
Through the coordination of long-endurance inspection and heavy-load transport, this operation leveraged the advantages of hydrogen-electric drones in flight range, adaptability to complex terrain, and emergency response speed, enhancing the efficiency of post-typhoon grid inspection and supply support, and further expanding the application scenarios of hydrogen-powered equipment in natural disaster emergency response.
