1st Small Scale LNG Plant Commissioned

Context

India’s goal to turn India into a gas-based economy has accelerated with the initiation of the first-ever Small Scale LNG unit. 

India launches 1st Small Scale LNG Plant

• GAIL (India) Ltd, the country’s biggest gas company, has commissioned this plant at its Vijaipur site in Madhya Pradesh.
• The Vijaipur facility has SSLNG skids capable of producing 36 tonnes of LNG daily.
  • It includes treatment skids (ZPTS) and liquefaction skids (cryo boxes) to convert natural gas into LNG.
• India plans to raise the proportion of natural gas in its primary energy mix to 15% by 2030, up from slightly over 6% currently, primarily because of its lower pollution emissions.

What is Small Scale LNG?

• SSLNG involves cooling and transporting natural gas on a smaller scale than usual methods. 
• Ensure delivery in remote areas: It uses special trucks and small boats to deliver liquefied natural gas (LNG) to businesses and industries in areas without pipelines.
• Management system: The SSLNG unit is managed by an automated SCADA system.
• SSLNG provides LNG to businesses and industries either in its liquid form or when it’s super-chilled. 
• • In more common situations like supplying CNG for vehicles or gas for homes, the LNG is turned back into gas before it’s delivered to the users.
• Establishment of SSLNG: SSLNG can begin at big LNG places or by making small LNG factories where there are lots of natural gas.
  • Example: GAIL’s SSLNG unit at Vijaipur is one example of starting small to get LNG at more places.

Advantages of Small Scale LNG (SSLNG):

• Enhanced Accessibility: SSLNG facilitates gas distribution in areas without access to natural gas pipelines, overcoming delivery challenges and expanding the availability of cleaner fuel options.
• Flexibility: SSLNG units are modular and can be quickly deployed to meet local demand, making them suitable for remote areas, industrial settings, and transportation needs.
• Promotes Sustainability: SSLNG encourages the adoption of cleaner fuels, reducing emissions when used in vehicles like trucks, buses, and marine vessels.
• Improves Energy Security: By decentralizing distribution, SSLNG enhances energy security and diversifies the sources of fuel supply.

Challenges and Limitations:

• Limited Vehicle Options: The availability of LNG-powered vehicles remains limited, which slows down the adoption of LNG as a fuel.
• Underdeveloped Retail Infrastructure: A lack of extensive LNG retail networks makes it challenging for consumers to access LNG fuel easily.
• Higher Initial Costs: LNG vehicles are usually more expensive to buy upfront compared to regular diesel cars.
• Financing Hurdles: The absence of specialized financing options for LNG vehicles poses challenges for prospective buyers looking to invest in this technology.
• Limited Pipeline Coverage: SSLNG faces challenges in areas where there is no existing natural gas pipeline network, hindering its distribution to remote locations.
• Regulatory and Permitting Issues: SSLNG projects may face regulatory hurdles and permitting delays, including environmental and safety regulations, which can slow down implementation and increase project timelines and costs.
