LPG is a naturally occurring by-product of natural gas extraction (60%) and crude oil refining (40%). It is therefore either used or it is wasted.
It is a combination of propane and butane molecules, along with trace amounts of other compounds.
LPG is colourless and odourless and a strong “stenching” agent is added so that even a very small leak can be easily detected.
At a normal temperature, LPG is a gas. When subjected to modest pressure or cooling, it transforms into a liquid. As a liquid, it is easy to transport and store. Once it has been cooled or pressurised, LPG is usually stored in containers made of either steel or aluminium.
When it comes to CO2 emissions, LPG is one of the cleanest fuels available. When used to power vehicles, LPG emits significantly less CO2 than petrol. As the targets set for vehicle emissions are becoming increasingly tighter, the use of LPG will not only contribute to a cleaner environment but will also help to sustain the profitability of the European automotive industry.
In domestic and industrial use, LPG generates an average of 15% less CO2 per kilowatt hour than oil, 50% less than coal and substantially less than the average European electricity distributed via the grid. All of this clearly suggests that the widespread adoption of LPG can make a major impact on reducing emissions of CO2.
