Sorption-enhanced reaction process (SEPR) can produce high yield of hydrogen with in-situ CO₂ removal using CaO. A key requirement for the process is the integration of effective Ca-based sorbents into catalytic schemes. In this work, the research progress of Ca-based CO₂ sorbents in SEPR is summarized. The positive effects by Ca-based sorbents are analyzed. The methods to improve the reactivity of Ca-based sorbents are discussed. A good prospect of compound materials of catalysts/sorbents in SERP is pointed out, for which the relationship between the performance and structure or reaction condition should be further studied. The optimization of process parameters is critically reviewed to provide recommendations for industrial operation. The comprehensiveness of this work extends to the discussion about the applications of Density Functional Theory study in SERP. Process economics requires the integrated H₂ production with by-product conversion, renewable resources utilization, waste recycling and heat coupling optimization for the future research.
