    Continuous Production of Clean Hydrogen from Wastewater by Microbial Usage
    (wiley, 2023) Satishkumar, P.; Isloor, A.M.; Farnood, R.
    Biohydrogen production from wastewater is a prominent way to address escalating global energy demand and alarming environmental pollution. The need for renewable, sustainable, economic, and environment-friendly pathways for energy generation is fulfilled by biohydrogen evolution. Wastewaters contain a vast array of organic contents, as well as microbes and are a suitable source for bioreactors. Treatment of wastewaters with hydrogen-generating bacteria significantly aids its purification process by reducing chemical oxygen demand with simultaneous hydrogen generation. Among the various methods that are available for hydrogen production from microbes, photo fermentation, dark fermentation, and microbial electrolysis cells are discussed thoroughly. Continuous hydrogen generation systems are most suitable for large scale commercial production. Uniform product quality is obtained in the case of continuous systems. Microbial electrolysis cells have been found to yield exceptionally good hydrogen purity. A variety of factors that affect hydrogen evolution in all the techniques are reviewed in detail. © 2023 Scrivener Publishing LLC. All rights reserved.

    Nonporous polymeric membranes for biohydrogen purification
    (Elsevier, 2025) Mendonca, N.R.; Isloor, A.M.; A.F., A.F.
    Biohydrogen generated from biomass is a clean form of hydrogen. The dark fermentation process for the generation of biohydrogen gives a mixture of H2 and CO2 from which biohydrogen needs to be purified. From the available methods for biohydrogen purification, membrane technology is the most viable since it is less energy-intensive and can be combined easily with other processes. Both polymeric as well as inorganic membranes are employed in gas separation processes. Of these, nonporous polymeric membranes are economically viable and are hence used in large-scale gas separations. The use of nonporous polymeric membranes, composed of polymers like polybenzimidazole, polyimide, and polysulfone, for biohydrogen purification is an ongoing area of research which can help to generate hydrogen for use in hydrogen fuel cells, hence reducing the dependence on fossil fuels which pollute the environment. © 2026 Elsevier Inc.

    Pilot scale studies for membranes in biohydrogen technologies
    (Elsevier, 2025) Antony, N.; Vijesh, A.M.; Isloor, A.M.
    Hydrogen (H2) is a cost-effective and green energy source that can be considered a substitute for conventional fossil fuels. Hydrogen-based fuel cells, supercapacitors, and batteries are used as energy storage devices in many commercial applications to make them a cleaner and more environmentally friendly process. Hydrogen produced from nonrenewable energy sources, such as oil, natural gas, and coal, is not cost-effective and involves processes that pollute our environment. Thus, developing economically viable and environmentally friendly processes is necessary to satisfy the massive demand for H2 as a green energy source. This chapter provides a comprehensive review of pilot-scale studies conducted in the field of membrane-based biohydrogen technology. © 2026 Elsevier Inc. All rights reserved.
