India Unveils its Largest Underground LPG Storage Cavern

A landmark achievement in India’s energy infrastructure was realized with the completion of the nation’s largest underground liquefied petroleum gas (LPG) storage cavern in Mangaluru. Capable of holding 80,000 metric tonnes of LPG, this state-of-the-art facility bolsters the country’s capacity to meet critical energy demands, particularly during emergencies.

The cavern, developed by Megha Engineering under the central government’s oversight, underwent a rigorous Cavern Acceptance Test (CAT) from May 9 to June 6 to verify its safety and operational integrity.

This marks the third underground storage facility in the Mangaluru region, joining the existing crude oil caverns at Permude (0.15 million metric tonnes) and Padur (0.25 million metric tonnes). Unlike its predecessors, this cavern is dedicated exclusively to LPG, surpassing the 60,000-tonne capacity of a similar facility in Visakhapatnam to claim the title of India’s largest.
