Xi'an Shiyou University has made new progress in the research on low-carbon utilization of high-carbon resources

Recently, the reporter learned from Xi'an Shiyou University that the scientific research team of Huang Fenglin, a professor at the School of Chemistry and Chemical Engineering of Xi'an Shiyou University, has made new progress in the research on the low-carbon utilization of high-carbon resources.
Innovative coal development and utilization technology to reduce the carbon emissions of coal-based products in the whole life cycle is a realistic choice to achieve the "dual carbon" goal. According to Huang Fenglin, the deep coal in-situ gasification hydrogen production technology route coupled with CCS/CCUS (carbon capture and storage/carbon capture, utilization and storage) can not only make efficient use of rich deep coal resources, but also is expected to become an ideal coal-based low-cost hydrogen production route, which has received extensive attention from the theoretical and industrial circles.
Based on China's "dual carbon" goal and the background of hydrogen energy development, Huang Fenglin's research team used the world's only kilometer-level deep coal in-situ gasification test data, based on the life cycle assessment method, combined with process simulation methods, to quantitatively measure and compare the carbon emissions, water consumption and external fossil energy consumption in the whole process of deep coal in-situ gasification hydrogen production and the existing industrial-scale fossil energy hydrogen production. At the same time, in view of the serious drawbacks of carbon dioxide emissions from coal-based hydrogen production, researchers have designed different capture schemes and compared the emission reduction effects based on the carbon dioxide emission characteristics of deep coal in-situ gasification hydrogen production routes. The results show that from the perspective of life cycle, compared with traditional coal surface gasification hydrogen production, deep coal in-situ gasification can reduce carbon emissions by 16.4% and reduce water consumption by 18.1%. "In the context of carbon constraint development, the research results can provide a scientific basis and evaluation basis for the demonstration and application of deep coal in-situ gasification hydrogen production technology, and at the same time help China's hydrogen production industry to transition from 'gray hydrogen' to 'blue hydrogen', and accelerate the realization of the 'dual carbon' goal." Huang Fenglin introduced.
