Chinese scientists have published research results related to nearly zero carbon emissions from coal power generation

When it comes to coal power generation, people often associate it with heavy pollution, high carbon emissions and low energy efficiency. However, this conventional perception is expected to be changed. On the 16th, a paper by the team of Academician Xie Heping from Shenzhen University was published in an international journal. They systematically constructed the technical implementation strategies and core technical architecture of the near-zero carbon emission direct coal fuel cell (ZC-DCFC), providing a new idea for breaking through the high emissions and low efficiency bottlenecks of traditional coal-fired power generation. 
This study elaborates on the technical challenges and research paths for ZC-DCFC in aspects such as fuel processing, development of key materials, design of single cells and fuel cells, in-situ near-zero carbon conversion, and analyzes and looks forward to the issues of cell-scaleup, long-term stability, carbon conversion efficiency, system integration, and application scenarios. 
Traditional coal-fired power plants are limited by the Carnot efficiency limit, with an energy conversion efficiency of approximately 45%. The coal consumption per unit of electricity generated remains high, and it is difficult to break through the barrier of deep coal decarbonization. Therefore, it is urgent to transform the traditional coal power generation methods and explore new technologies for clean, efficient, and nearly zero-carbon emission coal power generation. 
The near-zero carbon emission direct coal fuel cell power generation technology proposed by the team of Academician Xie Heping explores an innovative approach to the principle of coal power generation - instead of burning coal, it undergoes electrochemical oxidation through an oxide membrane, directly converting into electrical energy. At the same time, in the system, carbon dioxide is directly catalyzed, transformed, mineralized, and electrochemically processed, achieving near-zero carbon emission power generation and utilization while generating high-value products. Since 2018, the team of Academician Xie Heping has been continuously conducting research and development, and has successively made a series of progress in key high-performance material development for ZC-DCFC, battery mechanical failure mechanism and prevention, coal fuel activation treatment, and electrode microstructure optimization. 
The ZC-DCFC principle technology proposed in this research result helps to break through the inherent limitations of traditional coal power utilization, solve the carbon emission problem of coal-fired power generation, and convert coal into clean energy, providing new theoretical and technical support for the near-zero-carbon efficient utilization of coal.
