Technological Challenges in CBG Manufacturing in India - A Critical Review

Alok Gupta, Dr Anupam Jain, Nitin Kumar Bhageria

Abstract: Compressed Biogas (CBG) manufacturing in India faces significant technological hurdles, impeding the country's transition to renewable energy. Microbial strains and process control issues, including strain selection, process instability, and inhibitor compounds, further exacerbate production challenges. Gas cleaning and upgradation technologies, such as scrubbing, adsorption, and membrane separation, require optimization to ensure CBG meets quality standards. Automation and monitoring systems, including PLC-based control, SCADA systems, and IoT integration, are essential for real-time monitoring and improved efficiency. To address the existing challenges, several key recommendations emerge. Developing region-specific feedstock management strategies is crucial to ensure consistent supply and quality of feedstocks. This can be achieved through rigorous research and analysis of regional feedstock availability, quality, and variability. Also designing and optimizing digesters tailored to Indian conditions is vital to enhance CBG production efficiency. This involves considering factors such as climate, temperature, and feedstock composition to create digester designs that maximize biogas yield. Another critical area of focus is identifying and cultivating suitable microbial strains capable of thriving in Indian conditions. This requires collaborative research between academia, industry, and research institutions to develop microbial strains that can optimize biogas production. Furthermore, improving gas cleaning and upgradation technologies is essential to ensure CBG meets quality standards. This involves developing and implementing efficient gas cleaning systems, compression technologies, and bottling solutions.
