Liquefied Petroleum Gas (LPG) and Piped Natural Gas (PNG) differ primarily in how they are supplied to households. LPG is stored in cylinders and delivered through a distribution network that includes bottling plants, transport trucks and local dealers. Consumers must book refills and wait for cylinder delivery. PNG, by contrast, is supplied through an underground pipeline network directly to homes. Gas flows continuously from production fields or import terminals through the national grid and city gas distribution systems to household meters, eliminating the need for cylinder refills. Consumers pay for usage in a metered system similar to electricity or water, removing the need to book cylinder refills.
