Abstract:In order to make the technical routes and action plans for carbon neutralization clear, the energy structure, carbon emission status, key carbon emission industries, and forestry carbon sinks in Yunnan Province were analyzed as a case study. The technical route and four major action plans guided by the carbon neutrality goal of Yunnan Province were also summarized. The research results showed that Yunnan Province is rich in renewable resources and should give full play to the advantages of green energy and vigorously develop renewable energy such as hydropower, wind power, and solar energy. It was suggested to make full use of underground spaces such as abandoned mines, salt caverns, depleted oil, and gas reservoirs for energy storage, combine with carbon dioxide biochemical reaction to produce methane and mine pumped energy storage, to realize the utilization of carbon dioxide resources and large-scale energy storage. Yunnan Province should accelerate the development of the hydrogen energy industry, carry out the research and development, promotion and standardized production of related equipment and technologies such as hydrogen energy production, storage, transportation, and utilization, and promote the integrated construction of energy production, storage and utilization. It was also suggested to make full use of its resource advantages and promotes the implementation of the carbon neutral action plan. It was expected to achieve carbon neutrality in 2037 if 30% of the six main CO₂ emissions in Yunnan Province will be sequestrated. The research results have theoretical significance for carbon emission reduction and climate change mitigation, and also have important practical significance for Yunnan Province to achieve carbon peak and carbon neutral goals.
