Huzhou, August 16 (China News Service) (Bao Mengni) On August 15, the "Carbon Neutrality and Intelligent Energy Connection" seminar hosted by the Tsinghua University Carbon Neutrality Institute was held in Huzhou, Zhejiang, where academic experts discussed the transformation of the energy system towards carbon neutrality.
At present, about 82% of China's energy consumption is fossil energy, and China has pledged to achieve carbon neutrality by 2060, with non-fossil energy consumption accounting for more than 80%. In the view of Zhang Xiaoye, an academician of the Chinese Academy of Engineering and director of the Greenhouse Gas and Carbon Neutrality Testing and Assessment Center of the China Meteorological Administration, China is taking a carbon neutrality path that comprehensively coordinates development and security while taking into account international responsibilities.

"China needs to propose a global emission reduction scenario design plan based on its own path, rhythm, method and intensity of reducing anthropogenic carbon dioxide emissions," said Zhang Xiaoye.
In 2021, the China Meteorological Administration completed the construction of the first carbon sink monitoring and verification support system (CCMVS), which can objectively, comprehensively and timely monitor and verify changes in total anthropogenic carbon emissions and changes in carbon fluxes in terrestrial ecosystems at global, national, provincial, municipal and grid scales.
"This system solves the problem of transparency and normalization of global carbon balances at multiple scales. On this basis, we can more accurately predict future climate change, the risks caused, the resilience of different cities, etc. in a global scenario and form China's research." Zhang Xiaoye said.
The core of achieving carbon peak and carbon neutrality goals is the transformation of the energy system. In his keynote speech, Zhang Ning, associate professor of the Department of Mechanical and Electrical Engineering and Applied Electronics Technology at Tsinghua University, pointed out that ensuring the rapid growth of wind power and photovoltaic power generation is crucial to achieving the low-carbonization of the power sector.
"It is a systematic and complex problem for the power system to solve the problem of connecting a high proportion of new energy to the grid." He believes that it is necessary to plan the power system in a coordinated manner with sources, networks, loads and storage, and digitalization is the underlying foundation of the new power system. Digitalization empowers the new power system and can provide underlying support for the smooth operation of the system.
Today, China's new energy vehicle industry continues to grow and develop, responding to the global green and low-carbon transformation requirements. Xu Liangfei, associate professor of the School of Vehicle and Transportation Engineering at Tsinghua University, pointed out that among new energy vehicles, pure electric vehicles and hybrid vehicles are in the first place in the industry; fuel cell vehicles have greatly improved their technical level in recent years, and are entering the commercial promotion period after experiencing large-scale demonstration and verification at the 2022 Beijing Winter Olympics.
Combined with the team's research, he pointed out that the next step in promoting the use of fuel cells in the automotive field requires solving two problems: how to further extend the service life of fuel cells under automotive operating conditions, and how to reduce the cost of hydrogen use.
"Lowering the cost of hydrogen is related to hydrogen production, hydrogenation and hydrogen storage, not just the professional field of fuel cells." Xu Liangfei said that it is necessary to strengthen exchanges with the industry and enterprises to jointly promote the research of hydrogen fuel cells. (End)
