In this macroscopic study, we place a strong emphasis on practical applications, deliberately postponing microscopic details for future investigations. This approach reflects the urgency of our work and aims at advancing the technology swiftly while providing further refinement in future publications. For now, by compensating the lack of the microscopic perspective with comprehensive detail in our experimentation and data analysis this paper leaves no doubt about the feasibility and scalability potential of the novel route for HBCC. Thus, this work not only underscores fixed bed reactors as the most promising candidates for commercial HBCC , but also shifts the research agenda in this domain from pore-water to solid foams.
