Editorial Summary The Hindu, April 21, 2026 — The editorial analyses India’s critical dependence on the Strait of Hormuz for LPG imports, exposing a structural gap in India’s energy security architecture. While India maintains crude oil SPR covering ~9-10 days, LPG strategic reserves stand at only 140,000 tonnes — covering a matter of days for a country where over 330 million households depend on LPG (Pradhan Mantri Ujjwala Yojana beneficiaries included). The piece calls for underground LPG storage caverns, increased domestic production from offshore blocks, and acceleration of the Piped Natural Gas (PNG) network as a resilience-building substitute.
India’s LPG Dependency — The Numbers
Import Dependence
| Parameter | Value |
|---|---|
| Annual LPG consumption | ~29-30 million tonnes |
| Domestic LPG production | ~12-13 million tonnes |
| Import share | ~55-60% |
| Primary import source | Middle East (Saudi Arabia, UAE, Qatar) |
| Import route | Strait of Hormuz |
| LPG strategic reserves | ~140,000 tonnes (days of buffer only) |
| LPG beneficiary households | 330+ million (incl. PMUY) |
India is the world’s second-largest LPG consumer after China, and domestic production covers only about 55% of demand — the rest transits through the Strait of Hormuz.
The Strait of Hormuz Chokepoint
The Strait of Hormuz — a 39 km wide waterway between Iran and Oman — is the world’s most critical energy chokepoint:
- ~20% of global crude oil and petroleum products
- ~25-30% of global LNG trade
- The majority of India’s LPG imports
There is no alternative route for tankers coming from the Persian Gulf. If Iran mines or blockades the Strait (as it has threatened repeatedly), India’s LPG supply chain faces immediate disruption.
Why LPG Is Socially Critical in India
LPG is not just an energy commodity in India — it is a social equity and public health issue:
Pradhan Mantri Ujjwala Yojana (PMUY)
| Parameter | Value |
|---|---|
| Launched | May 2016 |
| Beneficiaries | 10 crore+ BPL households |
| Objective | Clean cooking fuel for women below poverty line |
| Ministry | Petroleum and Natural Gas |
| Impact | Reduced indoor air pollution (7th largest health risk) |
For PMUY beneficiaries — typically rural, low-income women — disruption in LPG supply means reversion to biomass burning (wood, dung cakes, crop residue), with severe health consequences:
- Indoor air pollution from biomass causes ~600,000-800,000 deaths annually in India
- Respiratory diseases, low birth weight, eye damage disproportionately affect women and children
Any Hormuz disruption that spikes LPG prices or creates physical shortages would disproportionately harm the most vulnerable households that the Ujjwala scheme was designed to protect.
India’s Strategic LPG Reserve — The Gap
Current Position
India’s strategic energy reserves compare unfavourably with LPG:
| Energy Type | India’s Strategic Reserve | Coverage |
|---|---|---|
| Crude oil | 5.33 MMT (Vizag, Mangaluru, Padur) | ~9-10 days |
| LPG | ~140,000 tonnes | Days only |
| Natural gas | Very limited | Minimal |
The contrast is stark: India has invested heavily in crude oil SPR but has almost no LPG buffer.
International Comparison
Countries with advanced LPG/energy storage:
- Japan: 90-day reserve across petroleum products; underground LPG caverns
- South Korea: Underground LPG cavern storage network
- EU: 90-day reserve standard under IEA membership
- India: Well below these standards for all categories
Underground LPG Cavern Storage — The Solution
What Are LPG Caverns?
Underground LPG cavern storage involves excavating salt caverns or rock caverns deep underground (300-1000 metres) to store liquefied petroleum gas under pressure:
- Natural salt caverns (solution mining in halite deposits) — the most cost-effective option used globally
- Mined rock caverns — expensive but suitable where salt deposits don’t exist
- India has salt deposits in Gujarat and Rajasthan potentially suitable for cavern development
Advantages
| Feature | Benefit |
|---|---|
| Large volume | Caverns can store millions of tonnes |
| Low surface footprint | Underground — no land acquisition conflict |
| Long-term storage | Salt caverns maintain integrity for decades |
| Fast draw-down | Can release stored LPG quickly during crises |
| Low operating cost | Once built, maintenance is minimal |
India’s Hindustan Petroleum Corporation Limited (HPCL) and Bharat Petroleum (BPCL) have studied underground LPG storage, but implementation has lagged due to upfront capital costs.
Domestic Production — The D-6 Block
The KG-D6 Block (Krishna-Godavari Basin, operated by Reliance Industries + BP) has revived India’s deepwater gas and NGL (Natural Gas Liquids, which include LPG components) production:
| D-6 Block Parameter | Detail |
|---|---|
| Operator | Reliance Industries + BP (51%:49% after 2011 restructuring) |
| Location | Krishna-Godavari Basin, Bay of Bengal |
| Peak production | ~60 MMSCMD (2010); declined; revived with R-series fields |
| Current status | R-Cluster, Satellite fields producing; MJ field added 2023 |
| LPG/NGL potential | Significant associated LPG from deepwater fields |
Accelerating production from domestic offshore blocks reduces import dependence and Hormuz exposure.
PNG Network — The Long-Term Substitute
Piped Natural Gas (PNG) for cooking is a cleaner, safer, domestically supplied alternative to LPG cylinders:
| PNG vs. LPG | PNG | LPG |
|---|---|---|
| Supply source | Domestic pipelines | Imported (Hormuz) |
| Price stability | More stable | Volatile with import prices |
| Safety | Continuous supply, no cylinder storage | Cylinder leakage risk |
| Rural reach | Limited (pipeline infrastructure) | Wide (last-mile cylinder delivery) |
| Current coverage | ~10 million households | 330+ million households |
India’s City Gas Distribution (CGD) network — under the regulatory oversight of PNGRB (Petroleum and Natural Gas Regulatory Board) — is being rapidly expanded to cover more Geographical Areas (GAs). The 11th and 12th CGD rounds have added hundreds of new districts.
For energy security, converting urban and peri-urban households from LPG to PNG reduces Hormuz-exposed demand — though rural coverage via PNG remains distant.
Policy Recommendations
- Build LPG underground cavern storage — target 30-day buffer by 2030; Gujarat salt beds as primary site
- Accelerate KG-D6 and other deepwater NGL production — reduce import share from 55% to 40% by 2030
- Expand CGD/PNG network — priority: top 500 towns; convert 50 million LPG households to PNG
- Diversify LPG suppliers — USA (shale LPG), Australia (LNG), West Africa as non-Hormuz alternatives
- Review PMUY refill economics — ensure low-income households retain LPG access even during price spikes
