Abstract: Under the goal of "carbon neutrality", alleviating the problem of new energy consumption and getting out of the environmental pollution dilemma are the main challenges faced by wind-coal enriched areas. This paper uses hydrogen energy as a coal intermediary to deeply integrate the rich wind and coal resources in wind-coal-rich regions in the industrial chain to form a wind-hydrogen-coal coupling system. Based on the system dynamics, the internal interaction and feedback mechanism of the wind-hydrogen-coal coupling system are clarified, a system dynamics model of the evolution and development of the wind-hydrogen-coal coupling system is established, and simulation is carried out by the Vensim software, moreover, the emission reduction effect and economic benefits of the wind-coal coupled development are emphatically analyzed. The results show that the wind-hydrogen-coal coupling system with green hydrogen as the fulcrum is economically and technically feasible, and the hydrogen storage can reduce carbon emissions by nearly 1.36 million tons with an economic benefit of 10 billion. The system can realize the development of economy growth and carbon emission decoupling by taking advantage of the renewable, low-cost wind power and the rich coal-based resources in the region, and help the wind-coal enriched areas achieve the goal of "carbon peak" by 2030 as scheduled.
