The Commodity Inspection and Testing Branch of Guangdong Liyuan Co., Ltd., a subsidiary of Guangdong Petroleum, has achieved a significant milestone by obtaining CMA certification for hydrogen analysis in proton exchange membrane fuel cell vehicles. This accomplishment marks the first instance among sales enterprises where full-item analysis and testing qualifications for hydrogen have been acquired. Guangdong Petroleum's focus on hydrogen detection technology has been accelerated through collaboration with the Research Institute of Petroleum Processing, resulting in the establishment of South China's inaugural full-item testing demonstration laboratory for vehicle fuel hydrogen. The successful on-site review by the Guangdong Provincial Market Supervision Administration further validates the laboratory's capabilities. As part of its strategic vision, Guangdong Petroleum is rapidly moving towards a dual-wheel drive model encompassing 'detection services + R&D.' This approach aims to create a comprehensive testing service platform that will be anchored in the Guangdong-Hong Kong-Macao Greater Bay Area and extend its influence nationwide. By integrating hydrogen detection and safety assessment services, the company seeks to bolster the development of the hydrogen industry chain. Leveraging resources from Sinopec's 'Ten Dragons' science and technology project, Guangdong Petroleum is not only enhancing its innovative capacities but also striving to elevate efficiency levels. This proactive stance exemplifies the company's commitment to fostering technological advancements and supporting the growth of the hydrogen economy.
