Advantages of Caverns

Based on the experience from Scandinavian and other countries, underground cavern storage of LPG is much safer than the above-ground pressurized spheres/bullets/ refrigerated tanks. About 80 caverns for LPG storage already exist in the world.

  • There is no risk of leakage and hence, the threat to the environment is minimal
  • They need much less land area than surface storage facilities
  • The natural landscape and scenic beauty of the project area is not affected as the major installations are located underground as compared to above-ground storage facilities
  • They can be used as buffer/ strategic storage for the country
