Abstract

The global energy transition is a widespread phenomenon that requires international exchange of expe-riences and mutual learning.Germany's success in its first phase of energy transition can be attributed to its adoption of smart energy technology and implementation of electricity futures and spot marketiza-tion,which enabled the achievement of multiple energy spatial-temporal complementarities and overall grid balance through energy conversion and reconversion technologies.While China can draw from Germany's experience to inform its own energy transition efforts,its 11-fold higher annual electricity consumption requires a distinct approach.We recommend a clean energy system based on smart sector coupling(ENSYSCO)as a suitable pathway for achieving sustainable energy in China,given that renew-able energy is expected to guarantee 85％of China's energy production by 2060,requiring significant future electricity storage capacity.Nonetheless,renewable energy storage remains a significant chal-lenge.We propose four large-scale underground energy storage methods based on ENSYSCO to address this challenge,while considering China's national conditions.These proposals have culminated in pilot projects for large-scale underground energy storage in China,which we believe is a necessary choice for achieving carbon neutrality in China and enabling efficient and safe grid integration of renewable energy within the framework of ENSYSCO.
