Piped Natural Gas (PNG) – India’s Shift in Cooking Energy
What is PNG?
- PNG (Piped Natural Gas) is natural gas supplied directly to households via pipelines for cooking and heating.
- Derived from domestic gas fields or imported LNG (regasified) and delivered continuously.
- Cleaner fuel: emits ~25% less CO₂ than LPG, no soot, no storage required.
Relevance
- GS III (Economy): Energy security, import dependence, subsidy burden.
- GS III (Environment): Cleaner fuel transition, emission reduction.
- GS III (Infrastructure): Gas grid, CGD networks, urban infrastructure.
Practice Question
Q1.Discuss the role of Piped Natural Gas (PNG) in India’s transition towards a gas-based economy. (10M)
LPG vs LNG vs PNG vs CNG
- LPG: Propane–butane mix; stored in cylinders; widely used for cooking.
- LNG: Natural gas liquefied at –160°C for transport; regasified at destination.
- PNG: Natural gas supplied via pipelines to homes/industries.
- CNG: Compressed natural gas used as transport fuel (vehicles).
Why India is Pushing PNG Now ?
- High LPG import dependence (~60%), vulnerable to geopolitics (e.g., Strait of Hormuz disruption).
- Natural gas has diversified global supply sources, improving energy security.
- PNG ensures continuous supply (no refill logistics) and reduces subsidy burden.
- Aligns with gas-based economy target (15% energy mix by 2030).
How PNG System Works ?
- Natural gas → Liquefied (LNG) → transported via LNG carriers → regasified → pipelines → households.
- Delivered through City Gas Distribution (CGD) networks for last-mile connectivity.
- Uses SE ID–like metering system (meter-based billing, no cylinder handling).
Can PNG Replace LPG?
- PNG is a “drop-in replacement” for cooking—similar flame, efficiency.
- 1 kg natural gas gives higher energy than LPG, making it efficient.
- No major behavioural change required for households.
- However, industrial uses may need equipment recalibration.
Why LPG Dominated Earlier ?
- Ease of last-mile delivery (cylinders via trucks even in remote areas).
- No need for expensive pipeline infrastructure.
- Strong government push via Ujjwala Yojana (33 crore connections).
- PNG requires high upfront capital and urban infrastructure readiness.
Economic Dimension
- PNG reduces import bill and subsidy burden on LPG.
- Lower logistics cost in long run (no transport/refill chain).
- High capex for pipelines (~25,000 km existing + 10,500 km under construction).
- Pricing needs to remain competitive with subsidised LPG.
Governance & Policy Push
- Target: 12+ crore PNG connections by 2034.
- CGD licences expanded to 300+ geographical areas.
- Policy reforms: time-bound approvals, mandatory PNG adoption in some areas.
- Push for switching households from LPG → PNG (dual holding restricted).
Challenges
- Pipeline infrastructure gaps—large regions (East, NE, South) under-covered.
- Last-mile connectivity issues in congested urban areas.
- 90 CGD areas not yet linked to trunk pipelines.
- High initial cost and slow adoption in rural/semi-urban areas.
- Limited storage capacity → LNG supply disruptions risk (just-in-time system).
Supply Constraints
- Current domestic gas production insufficient for mass PNG expansion.
- Need ~30–35% increase in production to meet future demand.
- ONGC KG Basin projects may boost output (~10–15%).
- Increased reliance on LNG imports inevitable.
Environmental Dimension
- PNG is cleaner than LPG and coal, aiding climate commitments (NDCs).
- Reduces indoor air pollution compared to biomass fuels.
- Supports transition to low-carbon economy.
Strategic Significance
- Reduces dependence on West Asia LPG supply chokepoints.
