Part of the Chemicals sector
Industry Overview
Industrial gases (oxygen, nitrogen, argon, hydrogen, helium, CO₂, specialty gases) are essential inputs for steel, healthcare, chemicals, electronics, and food processing. India's industrial gas market is ₹20,000-25,000 Cr and growing at 10-12%.
Key products
| Gas | Application | Delivery Mode |
|---|---|---|
| Oxygen (O₂) | Steel, healthcare, welding | Pipeline/cylinder/liquid |
| Nitrogen (N₂) | Food packaging, chemicals, oil & gas | Pipeline/liquid |
| Argon (Ar) | Welding, electronics | Cylinder/liquid |
| Hydrogen (H₂) | Refineries, chemicals, fuel cells | Pipeline |
| CO₂ | Beverages, food freezing, EOR | Cylinder/liquid |
| Specialty gases | Semiconductors, pharma, labs | Cylinder (high purity) |
Business models
| Model | Description | Margin | Contract |
|---|---|---|---|
| On-site (pipeline) | Dedicated plant at customer site | 20-30% | 15-20 year take-or-pay |
| Bulk (liquid tankers) | Central plant, delivered by tanker | 15-20% | 3-5 year contracts |
| Cylinder (packaged) | Small quantities via distributors | 25-35% | Spot/short-term |
| Specialty gases | High-purity for electronics/pharma | 30-50% | Technical contracts |

How industrial gas companies make money
The on-site model (best economics)
| Revenue Component | Description |
|---|---|
| Fixed charge | Covers capital recovery + fixed costs (paid regardless of offtake) |
| Variable charge | Based on actual gas consumed (covers power cost) |
| Escalation | Annual price increases linked to WPI or power cost |
The three delivery modes compared
| Mode | Investment | Margin | Contract | Customer |
|---|---|---|---|---|
| On-site (pipeline) | ₹100-500 Cr per plant | 20-30% | 15-20 years | Single large (steel, refinery) |
| Bulk (liquid) | ₹20-50 Cr per tanker fleet | 15-20% | 3-5 years | Multiple medium |
| Cylinder (retail) | ₹5-20 Cr per filling station | 25-35% | Spot/annual | Many small (welding shops, hospitals) |
Demand drivers
| End Market | Gas Demand | Growth Driver |
|---|---|---|
| Steel | 50-55% (O₂, N₂, Ar) | Steel capacity expansion |
| Healthcare | 10-15% (O₂, N₂O) | Hospital expansion + home healthcare |
| Chemicals/Refineries | 10-15% (H₂, N₂) | Refinery upgrades, hydrogen economy |
| Electronics/Semicon | 5-8% (specialty gases) | Fab plants (ATMP, Micron) |
| Food & Beverages | 5-8% (CO₂, N₂) | Frozen food, beverages |
