Researchers from the Institute of Atmospheric Physics of the Chinese Academy of Sciences and the Energy Research Institute of the National Development and Reform Commission published an opinion article entitled “China’s Carbon neutral goals: Challenges and Prospects” in the journal Advances in Atmospheric Science.With the goal of achieving peak carbon neutrality, how to find the optimal solution is a must-answer for scientists.Researchers from the Institute of Atmospheric Physics of the Chinese Academy of Sciences and the Energy Research Institute of the National Development and Reform Commission published an opinion article titled “China’s carbon neutrality goal: Challenges and Prospects” in the journal Advances in Atmospheric Science.”We analyzed the path to carbon neutrality using four models.The results show that there are significant differences in the paths to achieve carbon neutralization.Demand for nuclear, wind and biomass in all four paths is close to the upper limit of the country’s total resources, with only solar abundant.This shows that solar energy will play a key role in achieving carbon neutrality.”On January 26, Zeng Ning, a researcher at the Institute of Atmospheric Physics of the Chinese Academy of Sciences, told science and Technology Daily.Achieving carbon neutrality is an extensive and profound economic and social transformation.”This means that in our current energy mix, the ratio of fossil and non-fossil energy consumption needs to be completely reversed.”Zeng Ning said.The researchers’ projections, based on China’s Comprehensive Policy Review (IPAC) model, show that under the “dual carbon” goal, China needs to increase the share of non-fossil fuels to 77% by 2050, while reducing the share of fossil fuels to 23%, and that 23% of fossil fuels emit greenhouse gases.A large number of carbon sinks (such as terrestrial and Marine carbon sinks, carbon capture, utilization and storage technologies, etc.) are also needed to offset them.In other words, after carbon peak, fossil fuels will be replaced by clean renewable energy and nuclear energy.And this one great change will drive the whole social and economic development system of tremendous change.”In order to successfully realize the ‘yin-yang reversal’ of the energy structure in just 30 years, China must maintain strategic focus and formulate relevant policies scientifically and carefully to adjust the existing energy structure, so as to avoid the negative impact on society as much as possible.”‘These industries need to be properly guided to gradually reduce their dependence on and consumption of fossil energy resources,’ Zeng said.The general direction of decarbonization is clear. How to adjust the energy structure, how to allocate the share of solar, wind and biological energy in the renewable energy, and how to control the decline of the share of fossil fuels have become important and complicated “required questions”.Among renewable energy sources, solar energy is inexhaustible and less restricted than other sources of energy.Zeng and others point to distributed solar systems as a partial solution to the energy delivery problem.For example, to address the imbalance in energy production and demand between urban and rural areas, solar panels could be installed on rural farmlands, hillsides and other open areas.In addition to meeting local power needs, the electricity generated by these panels can also be sent to nearby towns via a microgrid to form a distributed solar system.”In addition to solving the spatial imbalance between energy generation and consumption in China, we should also pay attention to and give full play to the regional advantages of energy.”For example, the energy efficiency of onshore and offshore wind could be greatly improved in coastal cities, where wind could be an important “auxiliary” energy source for distributed solar systems, Tseng said.On the other hand, in warm and humid southern regions, where green vegetation is productive, scientific forest management is needed to maintain and enhance forests as a huge carbon sink.At the same time, Zeng said the goal of carbon neutrality requires everything to move in the right direction in a short period of time, including technological, socio-political and economic aspects.Therefore, sustained international cooperation and a favorable international economic and political environment are needed in the future to help China achieve its carbon neutrality goal as scheduled.Disclaimer: the above content is reproduced from China Energy net, the content does not represent the position of this platform.National Energy Information Platform Tel: 010-65367702, email: hz@people-energy.com.cn, Address: People’s Daily, No.2 Jintai West Road, Chaoyang District, Beijing
