Carbon Capture and Storage Via Electrochemical and Bioelectrochemical Techniques: A Review

Abstract

The urgent need to mitigate climate change has spurred innovative research in carbon capture and storage (CCS) technologies. Electrochemical approaches utilize electrocatalysis and electrochemical reduction to capture carbon dioxide (CO2) from industrial emissions, demonstrating high selectivity and enabling the production of valuable chemicals and fuels from captured CO2. Bioelectrochemical techniques leverage microorganisms to convert CO2 into biomass or biofuels, enhancing carbon capture efficiency through biological and electrochemical synergy. Integrating bioelectrochemical systems with renewable energy sources provides a carbon-negative pathway, aiding industry decarbonization. This review underscores the transformative potential of these techniques in revolutionizing CCS strategies, emphasizing their role in addressing climate change while fostering a sustainable, circular economy.
