This work investigated hydrogen production from biomass feedstocks (i.e., glucose, starch, lignin and cellulose) using a 100 mL h-type proton exchange membrane electrolysis cell. Biomass is promising process for production, although low in technology readiness level, but with series of recognised advantages: (i) lower-temperature conditions (compared to thermochemical processes), (ii) minimal energy consumption low-cost post-production, (iii) potential synthesise high-volume H2 (iv) smaller carbon footprint compared processes. A Lewis acid (FeCl3) was employed as charge carrier redox medium aid the depolymerisation/oxidation components. comprehensive analysis conducted, measuring CO2 emission volume performing electrochemical linear sweep voltammetry chronoamperometry) better understand process. For first time, influence temperature on current density evolution studied at temperatures ranging ambient 19 °C) 80 °C. The highest 12.1 mL, which produced by FeCl3-mediated glucose temperature, up two times higher than cellulose 1.20 V. Of substrates examined, also showed maximum power-to-H2-yield ratio 30.99 kWh/kg. results that can be feedstock when yield rate lower electricity water electrolysis.

Microbial electrolysis cells (MECs) are receiving increasing scholarly recognition for their capacity to simultaneously remediate contaminated streams and generate renewable hydrogen. Within the realm of acid mine drainage (AMD) treatment, MECs demonstrate pronounced advantages by merging pollutant mitigation with hydrogen production, thereby attracting intensified research interest. Drawing on 1321 pertinent publications extracted from Web Science Core Collection (2004–2024), this bibliometric assessment systematically elucidates current landscape prospective directions in MEC-based AMD remediation H2 synthesis. Key thematic areas encompass (1) a detailed appraisal distinctive publication dynamics within specialized domain; (2) insights into principal contributing nations, institutions, journals, academic fields; (3) synthesized overview technological milestones, emerging investigative foci, developmental pathways. By critically reviewing extant knowledge, evaluation offers meaningful guidance researchers newly engaging MEC-driven treatment while illuminating trajectories poised shape future evolving field.

With continuous depletion of fossil fuels, a hike in global temperature due to CO2 emissions, and increasing population Earth, the demand for alternative green renewable energy sources has become undeniable. Hydrogen, potential fuel production, can be produced way by water electrolysis with little no carbon emissions. As some parts world still face challenge drinking crisis, using clean, drinkable hydrogen production becomes concern. Households, agriculture, pharmacies, industries release lot polluted wastewater into environment, biological oxygen causing ecological imbalance. If is used as feedstock producing hydrogen, it address both crisis scarcity. In this review, from classified two parts: direct treatment methods followed generation. The technology, beyond all doubt, beneficial generation, reducing emission contributing net-zero future.

Switching to renewable resources for hydrogen production is essential. Present such as coal, oil, and natural gas are depleted rapidly moving a dead state, they possess high carbon footprint. Wastewater promising avenue in searching resource. Profuse techniques preferred production. Among them, electrolysis great with wastewater against biological processes by purity. obstacles behind the process conversion efficiency, intensive energy, cost. This review starts demand, availability, their H2 potential, then illustrates three main types of electrolysis. The section highlights energy-assisted because its low footprint zero emission potential various water High-temperature steam solid oxide viable option future scaling due versatile adoption photo, electric, thermal energy. A glance at some effective aspirations large-scale economics co-generation, biomass utilization, Microbial electrolysis, waste low-cost green electrode, Carbon dioxide hydrogenation, minerals recovery. study gives broader view facing challenges via perspectives eliminate above. along cost forward production, addition preserving environment from fossil fuel. Geographical seasonal availability constraints unavoidable; therefore, energy storage coupling power sources essential attain consistent supply. lack regulations policies supporting development these technologies did not reduce gap between research implementation. Life cycle assessment this rarely available, so we need focus on effect environment.

Photoelectrocatalytic hydrogen production is a sustainable energy technology that utilizes solar to decompose water into and oxygen. It offers the advantages of environmental protection sustainability. However, its low efficiency in photoelectric splitting results relatively small production, which severely limits popularization practical applications. This paper reviewed catalytic including principle catalysis, catalyst materials, reaction mechanism kinetics, conditions optimization, as well challenges prospects. The catalysts for efficient strategies improving rate were discussed detail, use catalysts, co-catalysts, integrated optimization photoelectrodes. also covered research on multi-physical field simulation optimization. provided comprehensive theoretical basis guidance related fields.
