What is Natural Gas?
Historical Background
Key Points
12 points- 1.
Natural gas is primarily methane, a simple hydrocarbon, making it a relatively clean-burning fossil fuel compared to coal or oil. When it combusts, it produces less carbon dioxide and fewer particulate matter pollutants, which is why it is often seen as a transitional fuel in the shift towards renewable energy.
- 2.
It is transported in various forms: as Piped Natural Gas (PNG) directly to homes for cooking, as Compressed Natural Gas (CNG) for vehicles, and as Liquefied Natural Gas (LNG) for long-distance shipping. LNG is natural gas cooled to -162 degrees Celsius, reducing its volume by about 600 times, making it economically viable to transport across oceans.
- 3.
India relies heavily on LNG imports to meet its natural gas demand, with roughly half of its requirement coming from international markets. A significant portion of these imports, over 50%, originates from West Asian countries like Qatar and the UAE, passing through the Strait of Hormuz.

Natural Gas Sector in India: Key Milestones
This timeline outlines the historical development and key policy interventions in India's natural gas sector, from its early recognition to the recent crisis management measures in 2026.
India's natural gas sector has evolved from initial domestic discoveries to a complex system reliant on both indigenous production and significant LNG imports. The PNGRB Act provided crucial regulatory stability, while the National Gas Grid aims for wider access. The 2026 crisis highlights the sector's vulnerability to global events and the government's role in managing essential supplies.
- Ancient TimesAccidental discovery and limited use of natural gas seeps in Persia and China.
- 20th CenturyWidespread industrial and domestic application of natural gas gains prominence globally.
- 1980s-1990sSignificant natural gas discoveries in India (e.g., offshore fields) spur development of initial gas infrastructure.
- 2006Petroleum and Natural Gas Regulatory Board (PNGRB) Act passed, establishing a regulatory framework for the sector.
- OngoingDevelopment of National Gas Grid and expansion of City Gas Distribution (CGD) networks for CNG and PNG.
- March 2026West Asia conflict disrupts LNG supplies via Strait of Hormuz. Government invokes Essential Commodities Act, prioritizes gas allocation (100% for domestic PNG/CNG/LPG, 70% for fertilizer, 80% for other industry, 65% for refineries).

Frequently Asked Questions
121. Many consider natural gas a "clean fuel." What's a critical environmental aspect often overlooked by aspirants that makes this statement nuanced?
While natural gas burns cleaner than coal or oil, producing less CO2 and fewer pollutants during combustion, the primary environmental concern often overlooked is methane leakage. Methane, the main component of natural gas, is a potent greenhouse gas, far more effective at trapping heat than CO2 over a shorter period. Leakages during extraction, processing, and transport significantly contribute to global warming, making its "clean" label more complex.
Exam Tip
Remember that "cleaner" doesn't mean "clean." Methane leakage is the key counter-argument to its environmental benefits.
2. During a natural gas supply disruption, what are the government's priority allocations under the Essential Commodities Act, specifically for domestic and industrial users?
Under the Essential Commodities Act, during a supply disruption, the government prioritizes natural gas allocation as follows:
- •100% of average consumption: Domestic PNG (households), CNG (transportation), LPG production, and essential pipeline operations.
