    Over the last five decades, solar-based hydrogen (H2) production has been intensively studied. Specifically, the study of biophotolysis by cyanobacteria has received great attention to produce H2, and promising research approaches have been established. To date, numerous photobioreactors (PBRs) have been built to collect cyanobacterial biomass and generate bioenergy. Additionally, different PBR parameters were adjusted to increase the product yield. PBR development holds great potential not only for cell biomass but also for biological H2 production. This review aimed to examine the mechanisms involved in H2 production by cyanobacteria, explore the factors influencing the process, and describe five distinct PBRs known for their high H2 production. This article examines the pros and cons of the most efficient PBRs for H2 production and offers insights into strategies for increasing their productivity. © 2023 Elsevier B.V., All rights reserved.

    The growing demand for clean energy has spotlighted biomass as a promising resource for sustainable hydrogen production, providing a carbon-neutral alternative to traditional fossil fuels. This review examines the latest advancements in converting biomass to hydrogen, focusing on thermochemical methods like gasification and pyrolysis, catalyst development, and biotechnological approaches such as dark fermentation and biophotolysis. While these methods offer substantial environmental benefits, including waste reduction and renewable energy generation, challenges persist in optimizing feedstock diversity, enhancing catalyst stability, and achieving cost-effective scalability. Innovations in plasma-assisted reforming, advanced nanocatalysts, and integrated reactor designs show promise in overcoming these barriers. By fostering collaboration across academia, industry, and government, these advancements can pave the way for a viable, sustainable hydrogen economy and contribute significantly to reducing global carbon emissions. © 2025 Elsevier B.V., All rights reserved.
