What is lng


What is LNG?

If natural gas is cooled down to temperatures of -160 ° C under atmospheric pressure, it creates liquefied natural gas, also known as liquefied natural gas (LNG). The advantage of this liquid gas compared to natural gas is the volume that is created by changing the physical state from gaseous to liquid: it is 600 times less than that of natural gas. So it can easily be stored in larger quantities.

In addition to the volume characteristics, LNG has the following properties:

  • Clear
  • Colorless
  • Not corrosive
  • Nontoxic
  • Odorless
  • Is not under pressure

Where is LNG promoted?

LNG can be extracted wherever there is a large amount of natural gas. For European needs, it is mainly imported from Russia, the USA and Qatar. The gas reservoirs are opened up by drilling and the natural gas in the stones is released, which can then be processed and transported. Appropriate cooling of the natural gas creates LNG.

What is the difference between LNG and LPG?

It is easy to confuse the two gases due to their similar abbreviations, but there are crucial differences between Liquefied Petroleum Gas (LPG), also known as LPG, and LNG.

compositionMainly from methaneButane and propane
useHeating, cooking, fuel for vehiclesPrivate and commercial use as LPG
storageAt low temperatureUnder high pressure
  • Lighter than air, spreads and thins quickly
  • Liquid at atmospheric pressure and very low temperatures (-160 degrees)
  • Heavier than air, gas does not disperse when it escapes
  • Liquid under high pressure at ambient temperature or under atmospheric pressure at -1 to -42 degrees

What should be considered when storing LNG?

Since LNG has to be stored at low temperatures, the tanks have to be designed accordingly so that there is optimal insulation. This includes an inner tank made of metal, which is surrounded by an outer tank made of concrete. In between there is thermal insulation that prevents the liquefied natural gas from heating up and at the same time protects it from evaporation.

How is LNG transported?

If natural gas is extracted, it is then cleaned and cooled. This creates LNG. The liquefied natural gas can be transported via tankers on which insulated storage tanks have been installed. With an LNG tanker, a distance of several thousand kilometers can easily be covered and the whole world can be supplied with liquefied natural gas. When it arrives at the port of destination, the liquefied natural gas is distributed by tankers or bunker ships. However, it can also be brought back into a gaseous state by heating in LNG terminals and then transported on to industries or households via natural gas pipelines. In this case, LNG is used like conventional natural gas.

Use of LNG: powerful fuel for trucks

LNG is used as a liquid fuel by various modes of transport such as ships, buses and trucks (trucks). In contrast to diesel, it is an environmentally friendly alternative that can still convince with high performance and range. Insulated storage tanks and a dual-fuel engine that can be used for LNG and oil-based fuels are required for use.

For freight forwarders in particular, LNG offers decisive advantages because it can reduce fuel costs. At the same time, emissions of sulfur oxide, fine dust, nitrogen oxide and CO2 are reduced - even noise emissions are reduced.

Trucks benefit from these advantages with LNG:

  • High efficiency
  • Great coverage
  • Lower fuel costs
  • Reducing emissions of sulfur oxide, fine dust, nitrogen oxide, CO2 and noise


  • We build your LNG tank infrastructure for fleets / forwarding agents (depot gas stations)!
  • We offer optimal tank solutions for various types of vehicles. We are guided by the desired storage size, number of pumps, LNG couplings per column and the operating pressure (Iveco, Volvo or both).
  • If you decide to expand your fleet with liquefied natural gas / LNG vehicles, we are your partner to set up an LNG filling station on your company premises. The minimum size of the LNG truck fleet is 20 vehicles.
  • If you have a smaller fleet, but an LNG filling station would still fit on your company premises, please contact us. We will find the best and flexible solution for you to lead your vehicle fleet with liquefied natural gas / LNG into the future.

LNG delivery (LNG transport)

BarMalGas has fleets of LNG tankers that are in use for customers 24/7. Deliveries to LNG or LCNG filling stations, CHPs, industrial plants or to the tank farm for the purpose of regasification and feeding into local gas networks are our core areas of liquefied natural gas.
Refueling of the fleet vehicles with LNG / liquefied natural gas
We are on the road for our customers with a mobile LNG filling station and refuel their LNG vehicles with liquefied natural gas on site.

LNG industry: when is it worth it?

With its small volume but high energy density, LNG is the best solution for large LNG industrial plants.

Systems that liquefy or compress natural gas reduce the volume of natural gas and thus increase the energy density per cubic meter many times over. The liquefied gas can easily be transported by truck, train or ship. The natural gas can be optimally fed into existing or newly created networks via direct regasification and / or storage in LNG tank farms.

LNG - fuel for ships

LNG bunkering / use of liquefied natural gas

The so-called truck to ship procedure was chosen as an alternative interim solution due to the lack of stationary filling station infrastructure at the ports. The new tanker-to-ship procedure is an additional option for using LNG as a ship propulsion system.
