Fuelling with CNG

Here, we will examine how Liquefied Natural Gas (LNG) can be used to fuel heavy-duty transport – buses, trucks and maritime vessels are covered.

As such, LNG as a fuel is the perfect substitute to diesel when it comes to transporting goods and heavy loads.

Here, on the gmobility platform, we try to cover more information regarding the use of gas in transport for non-professional uses. Nevertheless, LNG is important part of the transport system, which is also relevant to all of us. 

After all, we are dependent on the delivery and transport of goods! And now, with LNG, those can arrive to us in a sustainable way.

In the sections below, you will find answers to some of the more commonly asked questions when it comes to LNG and how it could be effectively used in transport today.

LNG (liquefied natural gas) is natural gas converted to liquid.

How does gas become liquid?

By cooling it to -163 degrees Celsius

For the purpose, it is stored in insulated containers that keep the gas liquid. LNG achieves a higher reduction in volume than with CNG, meaning that a larger amount can be transported over a longer distance. 

Natural gas from the Middle East is carried as LNG in special ships to Europe and the United States, where LNG is gasified and injected into the natural gas grid or distributed by road.

LNG use in vehicles offers the possibility to cover very long distances, making it an ideal fuel for trucks and buses. 

Compared to CNG the energy content of the unit of volume is three time higher: 1 liter Diesel fuel corresponds to 4,7 liter CNG at 200 bar and to 1,6 liter LNG.

The short answer to this question is no.

Even though both CNG and LNG constist of the same ingredient (methane), the two are having different properties

CNG is in a gaseous form – compressed to achieve the right density so that it can be used in an engine. LNG, on the other hand, is cooled down significantly, to the point that it transforms into a liquid form

Therefore, LNG can be used to power heavy-duty vehicles that need more power and use more of the fuel. At the same time, LNG has to remain at its cooled down temperature and heavy-duty vehicles are able to provide the necessary conditions for this to be sustainable whereas light-duty vehicles don’t need any such system using CNG.

Simply put, it’s the same fuel but different systems have different needs, addressed respectively by CNG and LNG.
