Abstract:Combined with the background of "double carbon" goal, this paper first analyzes the current situation of energy development in China, as well as the comparison of the number of hydrogenation stations between China and other major countries in the world; Secondly, using SWOT analysis to sort out the evaluation indexes which affect China''s hydrogen energy development strategy from the domestic and foreign environment, and giving the influence weight of each evaluation index on hydrogen energy development by establishing a four-tier AHP structure; Finally, the PCA algorithm is used to comprehensively evaluate the current situation of hydrogen energy development in major provinces in China by selecting six main indicators such as the installed capacity of new energy power generation, the number of hydrogen energy enterprises and the number of hydrogen refueling stations during the 14th Five Year Plan period. Combined with the GDP growth indicator, the synergy between hydrogen energy development and regional economic sustainable development is analyzed. The research shows that the cumulative number of hydrogenation stations in China accounted for 21.30% of the world by 2020, and the hydrogen production growth rate increased by 13.6% year-on-year; The domestic and international policies have the highest weight value for hydrogen energy development. Hydrogen storage and transportation has a relatively high disadvantage weight value, the same as the COVID-19 index. The comprehensive score of hydrogen energy development status in Guizhou, Guangxi, Yunnan and Hainan is relatively low, whose synergy with regional economic sustainable development is poor.
