Under the background of carbon neutralization, indirect coal liquefaction is facing huge pressure of carbon emission reduction. On the basis of advanced indirect coal liquefaction technology, an integrated system of indirect coal liquefaction and integrated gasification fuel cell (IGFC) with near zero CO2 emissions has been built. Through high-temperature fuel cells, coal-based syngas and Fischer-Tropsch synthesis tail gas can be directly used for efficient power generation, replacing the traditional self-contained power station to supply power and heat for the indirect coal liquefaction process. At the same time, CO2 enrichment of tail gas is realized, reducing the difficulty of CO2 capture. For the integrated system, the IGFC technical research progress was introduced, and the integrated demonstration of IGFC technology was carried out. Based on the indirect coal liquefaction unit, the first megawatt level IGFC test base in China was built,and the first 100 kW level IGFC test demonstration system with near zero CO2 emissions was developed, realizing continuous and stable operation. The fuel cell system generated 101.7 kW of power, with 53.2% of power generation efficiency and 98.6% of CO2  capture ratio.The feasibility of the integrated system is verified.
