Compressed Biogas and Its Role in India’s Energy Security
Key Points
Amid escalating geopolitical tensions in West Asia, India's energy security is under threat, highlighting the importance of Compressed Biogas (CBG) as a sustainable solution to reduce import dependency. This is crucial for UPSC aspirants, particularly in GS Paper 3, focusing on energy security and sustainable development. Last Updated: 15-07-2026
Key Facts About Compressed Biogas
- Definition: CBG is a purified form of biogas, chemically similar to CNG, used in transport, households, and industries.
- Objective: To reduce reliance on imported fuels by utilizing domestic organic resources.
- Key Provisions: Includes the SATAT initiative, CBG blending obligations, and biomass aggregation support.
- Numbers/Targets: SATAT aims to establish 5,000 CBG plants by 2023; only 132 completed by June 2026.
- Outcomes: CBG can enhance energy security, reduce pollution, and support rural economies.
India's Energy Security and Sustainable Development
Compressed Biogas is pivotal in achieving India's energy security and sustainable development goals. It aligns with India's commitment to reducing carbon emissions and achieving net-zero by 2070. The integration of CBG into the energy mix can significantly reduce dependency on imported fossil fuels, thus enhancing economic resilience. Globally, India can learn from Europe, China, and the USA, which account for 90% of global biogas production.
Related Government Schemes/Policies
- SATAT: Encourages the establishment of CBG plants to supply compressed biogas.
- GOBARdhan: Converts organic waste into biogas and bio-slurry, with financial aid for community plants.
- CBG Blending Obligation: Mandates phased blending of CBG with CNG and PNG.
- National Bioenergy Programme: Provides financial assistance for biomass conversion facilities.
- Biomass Aggregation Machinery Scheme: Supports machinery purchase for biomass processing.
