1. Executive Overview
As industrial manufacturers, steel mills, cement plants, and independent power producers transition away from expensive diesel, heavy fuel oil (HFO), and LPG, the choice between Liquefied Natural Gas (LNG) and Compressed Natural Gas (CNG) is a critical engineering and economic decision.
2. Volumetric Energy Density Comparison
The physical state of natural gas dictates how much energy can be stored and transported in a single trip:
| Parameter | CNG (250 Bar) | LNG (-162°C Liquid) |
|---|---|---|
| Volume Reduction vs Standard Gas | ~200 - 250x | ~600x |
| Cargo Payload per Tanker / Trailer | 6,000 to 10,000 SCM | 25,000 to 35,000 SCM |
| Economic Haulage Radius | Up to 250 km | 250 km to 1,500+ km |
| Storage Footprint on Site | Large (Multiple cascade bays) | Compact (Vertical cryogenic tank) |
| Recommended Daily Consumption | Under 25,000 SCMD | 25,000 to 250,000+ SCMD |
3. Decision Framework: When to Choose LNG vs. CNG
Choose CNG When:
- Pipeline mother station is within 200 km.
- Daily fuel requirement is below 20,000 SCMD.
- Lower upfront CAPEX is required.
Choose LNG When:
- Supply source is >250 km away.
- Daily fuel consumption exceeds 25,000 SCMD.
- On-site buffer storage for 5 to 10 days is vital.
