能源转型背景下电氢耦合项目的经济性研究现状与趋势

Status Quo and Trends of Research on Economics of Electro-Hydrogen Coupling Projects in the Context of Energy Transition

氢能作为一种清洁高效的二次能源,以其资源丰富、对环境无污染等优势被视为实现能源转型的重要推力。以2016—2022年WOS数据库中收录的电氢耦合项目经济性研究论文为统计源,借助COOC和VOSviewer软件分析电氢耦合项目经济性研究领域的研究现状与趋势发现:研究热点主要集中在可再生能源制氢、氢储能、氢能应用系统的平准化成本分析、系统成本最优方案及考虑绿证的项目经济性等方面。电氢项目经济性研究未来的发展趋势为:(1)储能/加氢一体站在交通领域应用的经济性研究;(2)探索开展可再生能源制氢在合成氨、甲醇、煤制油气以及冶金等行业应用的经济性研究;(3)不同碳减排激励机制对电氢耦合项目经济性的影响研究。

As a clean and efficient secondary energy source,hydrogen energy is regarded as an important thrust to achieve energy transition with its advantages of abundant resources and no pollution to the environment.The research papers on the economics of electro-hydrogen coupling projects included in the WOS database from 2016—2022 were used as a statistical source and bibliometric analysis was conducted with the help of COOC and VOSviewer software to analyze the research hotspots and make research outlook in the field of economics of electro-hydrogen coupling projects research.The results show that the research hotspots are mainly focused on hydrogen production from renewable energy sources,hydrogen storage,levelised cost analysis of hydrogen energy application systems,optimal system cost solutions and project economics considering green certificates.The future trends in the study of the economics of electro-hydrogen projects are:(1)the economics of integrated energy storage/hydrogen refueling stations in the transport sector;(2)the economics of renewable energy hydrogen production in the ammonia,methanol,coal-to-oil and metallurgy industries;(3)the impact of different carbon emission reduction incentives on the economics of electro-hydrogen coupling projects.
