Abstract
- Biohydrogen (BioH <subscript>2</subscript> ) is considered as one of the most environmentally friendly fuels and a strong candidate to meet the future demand for a sustainable source of energy. Presently, the production of BioH <subscript>2</subscript> from photosynthetic organisms has raised a lot of hopes in the fuel industry. Moreover, microalgal-based BioH <subscript>2</subscript> synthesis not only helps to combat current global warming by capturing greenhouse gases but also plays a key role in wastewater treatment. Hence, this manuscript provides a state-of-the-art review of the upstream and downstream BioH <subscript>2</subscript> production processes. Different metabolic routes such as direct and indirect photolysis, dark fermentation, photofermentation, and microbial electrolysis are covered in detail. Upstream processes (e.g. growth techniques, growth media) also have a great impact on BioH <subscript>2</subscript> productivity and economics, which is also explored. Technical and scientific obstacles of microalgae BioH <subscript>2</subscript> systems are finally addressed, allowing the technology to become more innovative and commercial.<br /> (Copyright © 2021 Elsevier Ltd.
