Replacing CNG With LPG Is Not Good Economics

So long as cars can run on compressed natural gas, liquefied petroleum gas (LPG) should be used for more useful purposes, head of the Iran CNG Association said.
“Iran has some of the world’s largest natural gas resources and grids in the world. Substituting CNG with LPG in the energy mix does not make economic sense,” Ardeshir Dadras was quoted as saying by IRNA.
He said the capacity to produce LPG is limited. Moreover, there are two million households that are not yet linked to the national gas grid and need LPG for cooking needs.
Around 20,000 tons of LPG is produced in Iran every day, half of which is sold in regions that still do not have piped gas, namely in the southern provinces like Sistan-Baluchestan and Kerman.
