Algae as a substrate for biogas production: A review of key findings from literature on process optimization

Original language description

Algae have gained attention as a promising feedstock for biogas production due to their rapid growth, high lipid content, and adaptability to diverse environments, including freshwater and wastewater. This review, based on an analysis of the current literature, examines the potential of various algal species in anaerobic digestion, emphasizing the importance of optimizing process parameters to enhance biogas yield.Key factors influencing methane production include the choice of algal species, temperature conditions, organic loading rate (OLR), and hydraulic retention time (HRT). Microalgae like Chlorella vulgaris have shown high methane yields, making them particularly promising. However, optimizing the carbon-to-nitrogen (C/N) ratio is crucial for preventing process issues like ammonia inhibition, ensuring stable and efficient methane production. The adaptability of algae to different anaerobic digestion conditions allows for flexibility in application, but also highlights the need for tailored approaches to maximize yield.Overall, algae present a viable and flexible substrate for biogas production, offering opportunities for process enhancement through careful control of key parameters. By integrating algae into biogas plants, it is possible to improve both the sustainability and efficiency of renewable energy production.This work was financially supported by the European Union under the REFRESH - Research Excellence For Region Sustainability and High-tech Industries, CZ.10.03.01/00/22_003/0000048via the Operational Programme Just Transformation.
