Context: Top officials from the Ministry of Petroleum and Natural Gas (MoPNG) held a joint review meeting, to expedite the expansion of Piped Natural Gas (PNG) networks.

About Piped Natural Gas (PNG):

What It Is?

  • Piped Natural Gas (PNG) is a safe, convenient, and environment-friendly fuel used for domestic, commercial, and industrial purposes.
  • It primarily consists of methane and is delivered directly to the point of use through a network of pipelines, eliminating the need for cylinder storage and heavy-duty transport.

How It Works?

  • Source and Transmission: Natural gas is transported from production fields or import terminals through high-pressure trunk pipelines.
  • City Gas Distribution (CGD): CGD entities receive the gas at City Gate Stations, where the pressure is reduced for safe urban distribution.
  • Local Network: Gas is moved through a primary network of steel pipes and then into a secondary network of Polyethylene (PE) pipes laid across neighborhoods.
  • Last-Mile Connectivity: The gas is finally delivered to individual households, kitchens, or industrial units through small-diameter GI (Galvanised Iron) or copper pipes.
  • Integrated Planning: To avoid delays, these networks are now being mapped on the PM Gati Shakti National Master Plan portal for coordinated underground utility integration.

Key Characteristics:

  • Continuous Supply: PNG is available 24/7, removing the hassle of booking, waiting for, or changing heavy LPG cylinders.
  • Safety: Natural gas is lighter than air; in the event of a leak, it disperses rapidly into the atmosphere, significantly reducing the risk of fire or explosion compared to LPG.
  • Space Saving: Since the fuel is piped, there is no need for space to store cylinders or bulky fuel tanks.
  • Economical and Efficient: It is generally more affordable than traditional fuels and requires no manual handling, which minimizes transit losses and theft.
  • Billing Accuracy: Consumption is measured through a meter, ensuring users only pay for the exact amount of gas used.

Significance:

  • Expanding PNG networks reduces the country’s over-reliance on bottled LPG and diversifies the energy mix.
  • As a cleaner-burning fossil fuel, PNG helps reduce urban air pollution and aligns with global climate mitigation goals.
