Amid growing efforts to combat climate change, bioelectrochemical systems (BES) have gained attention as a sustainable technology for converting carbon dioxide (CO₂) into value-added products, particularly methanol. This chapter reviews recent advancements in BES for CO₂-to-methanol conversion, covering core components, microbial and electrochemical innovations, and integrative strategies that enhance system performance. Key topics include the evolution of reactor design, novel electrocatalysts, electron transfer mechanisms, and the integration of renewable energy. Broader BES applications in hydrogen production, wastewater treatment, and bioplastics synthesis are also discussed. The chapter highlights the role of digital technologies, alongside techno-economic and environmental assessments, in advancing BES towards scalable deployment in future circular bioeconomy models.
