The Yangtze River Delta region is a key area for the development of hydrogen fuel cell vehicle industry in China. At the present stage，it has begun to take shape，forming the whole industry chain covering from upstream hydrogen production，storage，transportation and hydrogenation infrastructure，midstream hydrogen fuel cell reactor and system core components to downstream hydrogen fuel cell vehicle production and operation. To support the development of the hydrogen fuel cell vehicle industry，Shanghai and Jiangsu，Zhejiang and Anhui provinces have issued a series of local development plans and supporting policies. With the accelerated development of the industry，by encouraging and supporting the development of hydrogen production by renewable energy and CCUS technology，focusing on the technical barriers of hydrogen storage and transportation，and exploring the application scenarios of hydrogen fuel cell vehicles，the Yangtze River Delta will continue to improve the liquid concentration of hydrogen industry and lead the development of hydrogen industry in China.
