The number of Autogas vehicles operating on roads is expected to reach 22.6 million by 2020, according to a report from Pike Research.
The 'Propane Autogas Vehicles' report revealed that the rise in autogas vehicles will be due to the reduced cost per gallon of autogas over the gasoline or diesel in many countries.
Pike Research senior research analyst David Alexander said as with any fuel, availability is the key to rise in market.
"Unfortunately, fuel suppliers have taken the view that no need exists to grow the infrastructure if not that many vehicles are equipped to use the fuel," Alexander said.
"Some form of incentive will be needed to kick-start growth if autogas is going to advance."
The report also reveals that internal combustion engines, including both diesel and gasoline, can be converted into LPG and can be operated on dual fuel.
