Discover compressed natural gas, an alternative fuel of the future
An increasing number of people are concerned about climate change and global air quality. Others are frustrated by prices at the pump when they have to fill up their vehicles. These current very real challenges are leading many individuals and entrepreneurs to take an interest in clean energy sources, particularly alternative fuels.
For these people, the use of compressed natural gas is part of a strategy to reduce their dependence on traditional fossil fuels. Therefore, it makes sense to take an interest in this alternative fuel and demystify it.
What is compressed natural gas?
Conventional natural gas is a fossil fuel that occurs naturally in gaseous form in the porous rocks of subsoil. It is generated from millions of years of organic matter sedimentation. It can also be obtained through a process that uses the gases emitted during biomass decomposition.
Compressed natural gas (CNG) is an alternative fuel obtained by compressing natural gas to less than 1% of its standard atmospheric volume, or about 3,600 PSI. This product can be used to replace gasoline or diesel in any light or medium vehicle or heavy truck equipped with a CNG conversion kit or CNG powered engine.
A brief history of the use of compressed natural gas as fuel for vehicles
At the end of the 19th century, this energy source was first used as a fuel for vehicles, with the first natural gas car patented in the United States. Shortly after the Second World War, Italy and a number of other European countries adopted compressed natural gas (CNG) to meet a significant portion of their fuel needs.
Over the last few decades, significant technological advances have made it possible to develop CNG engines that are increasingly cleaner and safer and can be installed on vehicles mass-produced by different manufacturers. Today, there are over 15 million CNG-powered vehicles in the world.
CNG in a combustion engine: as safe as gasoline
Since CNG is a compressed form of the same gas used as fuel in homes for heating and cooking, it can also be used in a combustion engine. CNG flows from the compression tanks to a regulator and from there it is injected into the engine, just like regular gasoline in a conventional internal combustion engine. However, this type of engine emits 25% less greenhouse gases than a diesel engine, while saving you nearly 30% at the pump.
Natural gas only ignites inside a combustion chamber. If there is too much natural gas, there will not be enough oxygen for it to ignite. The same is true if there is too little natural gas, the too low ratio will not allow the gas to ignite. It is a delicate balance that must be respected. This contributes to making CNG vehicles as safe as conventional fuel vehicles. Even refueling is very safe.
Contribute to a greener future by leveraging CNG
In light of this information, you undoubtedly have a better understanding why compressed natural gas could be a major ally in the fight against climate change, particularly as an alternative fuel in vehicles.
