Abstract
Hydrogen energy,as a clean and efficient secondary energy source,plays a crucial role in achieving carbon neutrality.Renewable energies such as wind and solar power are also crucial forces for realizing the"dual-carbon"goals.In China,the rapid expansion of wind and photovoltaic(PV)installations has increasingly highlighted several challenges,including limited grid integration capacity,insufficient system flexibility,and bottlenecks in cross-regional power transmission.To address these integration challenges and to build a zero-carbon energy system,this study analyzes the advantages and bottlenecks of wind,solar,and hydrogen energy in China's renewable energy development,and explores the development pathway of electro-hydrogen synergy.The results indicate that electro-hydrogen synergy can integrate wind and solar resources with hydrogen technologies to form a complete green energy ecosystem and enhance international competitiveness.The core of electro-hydrogen synergy lies in establishing a bidirectional"electricity-hydrogen"coupling mode of energy utilization,guided by the principle of"electricity first,electricity whenever possible,hydrogen when necessary".The application scenarios of green hydrogen are continuously expanding,providing comprehensive solutions for the decarbonization of energy systems.Liquid organic hydrogen carrier(LOHC)technology represents an important pathway for resolving hydrogen storage and transportation challenges,and it will further consolidate the electro-hydrogen synergy framework.The next five to ten years are identified as a critical period for the maturation of the electro-hydrogen synergy model.In conclusion,electro-hydrogen synergy is not only a solution to the current bottlenecks in renewable energy integration,but also a core pathway toward building a zero-carbon energy system,with the potential to become an essential pillar of sustainable development.关键词
