“…This is due to the slower gasification rate of char from coal in the IG-CLC due to its lower volatile content when compared to the paper and plastic samples. It was inferred from the energy analysis on the CLC of biomass sawdust done by Kevat and Banerjee 35 that the complete combustion, which is determined from the char gasification step, is proportional to the energy output. The statement above is supposed to infer that coal should have the lowest energy output in the IG-CLC as it has the lowest volatile content.…”

Chemical looping combustion (CLC) is a novel carbon capture and storage technology that can be used in the proper disposal of municipal solid waste when used as a solid fuel. In this study, the results of the CLC of paper, plastics, and paper/plastic blends were compared with CLC of South African coal using Chemcad software. The simulation was done for two different CLC processes, namely, chemical looping oxygen uncoupling (CLOU) and in situ gasification CLC (IG-CLC). The results demonstrated that coal at 66% had a lower CO 2 yield than paper (86%) but a higher yield than all the plastic samples in CLOU (3356%) and an equal CO 2 yield in paper and all plastic samples in IG-CLC. Furthermore, coal had a lower CO 2 gas yield than all the optimum blends (72–85%) for CLOU and an equal yield with the entire paper/plastic blend in IG-CLC. On combustion efficiency, coal has a lower combustion efficiency at 80% than paper and polyvinyl chloride (PVC) at 90 and 96%, respectively, but a higher efficiency than other plastic samples that are between 30 and 70% in CLOU while in IG-CLC, it had a lower efficiency than paper, PVC, and polyethylene terephthalate and higher efficiency than high-density polyethylene, low-density polyethylene, polypropylene, and polystyrene. For paper/plastic blends, coal has higher combustion efficiency than all the paper/plastic blends in both CLOU and IG-CLC processes except for the paper/PVC where the combustion efficiency was higher than coal.

Chemical looping combustion of solid biomass has the unique potential to generate energy with negative carbon emissions, while entailing an energy penalty compared to traditional combustion that is lower than that of the competing carbon capture technologies. In spite of these attractive features, research is still needed to bring the technology to a fully commercial level. The reason relies on a number of technological challenges mostly related to the oxygen carrier performance, its possible detrimental interaction with the biomass ash components, and the efficiency of the gas–solid contact with the biomass volatiles. This review is focused on these specific challenges which are particularly relevant when firing biomass rather than coal in a solid-based chemical looping combustion process. Special attention will be given to the most recent findings published on these aspects. Related performance evaluation by modeling, system integration, and techno-economic analysis will also be briefly reviewed.

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.
