Understanding CBG Cascades and Storage Systems
A look inside the backbone of Bio-CNG logistics — cascades that store, transport, and stabilize green energy delivery.

From anaerobic digesters to purification skids — discover the tech engines powering India's Bio-CNG movement.
The Bio-CNG revolution rests on innovation — in biogas purification, upgrading, and compression technologies. Each stage converts organic waste into clean, usable fuel.
1. Anaerobic Digestion (AD) Technology
Organic feedstock like press mud, Napier grass, and food waste undergo microbial breakdown in oxygen-free digesters, producing raw biogas rich in methane (55–60%).
2. Biogas Purification Units
Advanced systems like water scrubbing, PSA (Pressure Swing Adsorption), and membrane separation remove CO₂, H₂S, and moisture, yielding >96% pure methane gas.
3. Compression and Cascade Integration
After upgrading, CBG is compressed up to 250 bar and stored in cascades for easy dispatch.
4. Smart Control Systems
IoT-enabled PLCs and SCADA interfaces monitor plant operations, safety, and energy balance in real time.
