Analysis and Prospect of Key Technologies for CCUS Coupling Hydrogen Production

Systematically studied the process principle, system construction, supporting equipment and application scenarios of CCUS key technologies, and deeply analyzed the carbon dioxide capture purification and comprehensive utilization technology; At the same time, the process principle and development status of various key technologies for hydrogen production in the field of hydrogen energy development are presented in detail, mainly including hydrogen production from fossil fuels, hydrogen production from electrolytic water, hydrogen production from high-temperature cracking of chemical raw materials, hydrogen production from industrial by-product gas and other key hydrogen production technologies. The advantages and disadvantages of various hydrogen energy production technologies are compared and analyzed. Finally, based on the low-carbon, clean and sustainable development strategy, the development route and supporting process system of low-carbon hydrogen production key technologies coupled with CCUS technology are deeply analyzed, and innovative proposal of CCUS coupled hydrogen production process system. At the same time, in-depth thinking and practical prospect are carried out to realize the sustainable and large-scale development direction of hydrogen energy. The analysis shows that with the implementation of the global carbon-neutralization strategy, the development potential of green, low-carbon and renewable new energy represented by hydrogen energy is huge. However, as the main source of hydrogen energy, the use of fossil fuels for hydrogen production seriously restricts the large-scale utilization of hydrogen energy due to the high carbon emissions in the hydrogen production process. Therefore, actively promoting the research and project construction of CCUS coupled hydrogen production key technologies is of great significance for promoting global energy structure transformation, as well as deep emission reduction and comprehensive utilization of carbon dioxide.
