“…SE-BCLG involves the introduction of an adsorbent (CaO) into the BCLG process, which adsorbs the generated CO 2 in real time, thereby further facilitating the reaction. , Using adsorbents, the concentration of CO 2 in the reaction environment is reduced, which promotes the decomposition of more hydrocarbons and the generation of hydrogen and enhances the hydrogen yield. The technology not only improves gasification efficiency but also enables efficient CO 2 capture, mitigating greenhouse gas effects.…”

Biomass-based chemical looping (BCL) emerges as a highly prospective technique for generating high-purity H 2 , distinguished by its minimal energy penalties and potential for negative carbon emissions. However, its industrial implementation faces significant challenges owing to the intricate interactions in solid−gas reactions and the heat and mass management within the reactors. This work comprehensively reviews the current advancements in BCL H 2 production (BCLHP), emphasizing oxygen carrier selection, reactor design, system integration, and technoeconomic assessments. It highlights that BCLHP surpasses traditional biomass gasification methods in efficiency, resulting in reduced costs and net negative CO 2 emissions (−17.00 kg of CO 2 / kg of H 2 ). Fe-based oxides are deemed the most appropriate oxygen carriers; however, their utilization is constrained by high fabrication costs and the absence of scalable synthesis methods. Additionally, the uneven and intricate heat and mass transfer present substantial obstacles to scaling up the redox reactors. These issues collectively elevate construction costs and limit the application of BCLHP to laboratory or pilot scales. Significant technological challenges and research gaps in experimental and modeling studies undermine the reliability of simulation outcomes. Therefore, addressing these challenges necessitates developing suitable oxygen carriers and their scalable production methods, stable redox reactors, and overall system scalability. In conclusion, while BCLHP holds considerable promise for high-purity H 2 production and negative emissions, advancing it to practical applications will require innovative advancements in both the experimental and modeling domains.

Renewable energy integration and operational optimization are crucial in energy sustainability and decarbonization, especially for industrial steam power systems (SPS). This study establishes an SPS superstructure that integrates wind, solar, and biomass energy. A mixed‐integer nonlinear programming (MINLP) model is developed to determine an optimal retrofit strategy that minimizes the life cycle cost, which includes carbon emission cost and energy cost. To solve this high‐dimensional complex optimization problem, a multistage strategy fusion differential evolution algorithm with dynamic partitioning of the SVM feasible domain (SVM‐MS‐DE) is developed. The results from the optimal strategy demonstrate a 9.02% reduction in the system's total cost and a 9.64% decrease in carbon emission through the incorporation of wind and solar energy. Additionally, the sensitivity analysis on biomass ratio, carbon emission price, energy demand, and carbon emission limits reveal that the region can contribute significantly to renewable energy initiatives. Several recommended policies are provided to encourage enterprises to move towards sustainable development.
