“…Lee et al (2021) researched the efficiency of wet oxidation (a kind of heat treatment) in the pretreatment process of anaerobic digestion of palm oil wastes and found that it was possible to significantly increase methane gas production by adding cattle compost (Lee et al, 2021). Rai et al (2022) suggested that diatoms may be useful for hydrogen production in microbial fuel cells and photobioreactors to cultivate photosynthetic organisms (Rai et al, 2022).…”

Biomass-based hydrogen production is an innovative approach to realize carbon-neutral energy solutions. Despite their promise, both structures differ in terms of the biomass energy domain, which is at the entry point of the technology, and the hydrogen energy domain, which is at the exit point of the technology. In this study, we conducted structural and predictive analyses by cross domain bibliometric analysis to clarify the differences in the structures and perspectives of researchers in cross domains and to suggest ways to strengthen collaboration to promote innovation. Our study reveals that the hydrogen energy domain has a balanced discussion on realizing a hydrogen society using biomass-based hydrogen production technology, while the biomass energy domain has a strong interest in the process of processing biomass. We find that changing perspectives in any academic domain presents a different structure. This comparative analysis reveals the importance of synergistic progress through interdisciplinary efforts. By filling these gaps, our findings contribute to a roadmap for future research and policy development in renewable energy and highlight the importance of a unified approach to sustainable hydrogen production.

“…By employing the QS-QQ method, which involves live bacteria as a catalyst to transfer electrons from the wastes to the anode, the process of bio-generation of electricity in a MFC can be enhanced. The use of METs, especially MFCs integrated with QS-QQ has been proven as a cutting-edge tool for bio-electricity and bio-hydrogen production [ 31 ]. Also, utilising solid or liquid waste as feedstock integrated with microalgae [ 32 ] has the potential to revolutionise the industry [ [32] , [33] , [34] ] by treating wastewater [ 35 ], creating biosensors [ 36 ], and bioremediation of contaminants [ 37 ].…”

Efficient hydrogen storage is essential for its use as a sustainable energy carrier. Diatomaceous earth, a high-surface-area siliceous geomaterial, shows potential as a physisorption material for hydrogen storage. This study analyzes diatomaceous earth's long-term characteristics when subjected to high-pressure hydrogen injection. The diatomaceous earth was subjected to a hydrogen pressure of 1200 psi for a period of 80 days at room temperature. Neither notable morphological or mineralogical changes were observed. Nevertheless, there was a slight reduction in fine particles and a slight increase in larger particles. The Brunauer−Emmett− Teller (BET) surface area decreased slightly with a significant decrease in pore width. However, the hydrogen adsorption at 77 K temperature was increased significantly (45.5%) after the hydrogen storage test. Moreover, there was a delayed release of molecular water as the temperature increased. These changes suggest that a condensation reaction has occurred involving some of the opal-A silanol groups (Si−O−H), producing molecular water. Bonding through siloxane bridges (Si−O−Si) results in a significant decrease in pore width and increased hydrophobicity (i.e., the interaction between diatomaceous surface and H 2 was increased), thereby enhancing hydrogen adsorption capacity. These findings indicate that diatomaceous earth holds promise as a material for hydrogen storage, with the potential for its hydrogen adsorption capacity to improve over time.
