Research on the Effectiveness of Power Technologies for Achieving Carbon Neutrality in China

China has announced its target to achieve carbon neutrality by 2060, and this achievement ought to start with transforming the current power system to a new low-carbon system dominated by renewable energy. To facilitate the transformation, low-carbon power technologies play an important role. To explore the emission reduction effect of low-carbon power technologies, this paper first proposes an analysis model that examines the emission reduction effect of different low-carbon technologies in numeric terms. Based on the proposed calculation method and relevant predicted values, the reduction effects of five low-carbon technologies, including solar-thermal power generation, virtual synchronous, grid-side energy storage, demand response, and carbon capture and storage, are discussed. The results show that these technologies can effectively promote decarbonization in the power sector. This study is helpful for the power industry to choose suitable technology development paths and assist in the decomposition and optimization of emission tasks.
