What is LNG and CNG and how do you safely refuel?
Frequently asked questions
What’s the difference between LNG (liquefied natural gas) and CNG (compressed natural gas)?
LNG (liquiefied natural gas) is natural gas cooled to -161º so that it condenses and is converted into a liquid. This reduces its volume 600-fold compared to its gaseous state, creating storage capacity to provide excellent range.
Recommended for use with heavy vehicles.
CNG (compressed natural gas) is a colourless and highly flammable gas. It is lighter than air. CNG for commercial use contains a slight sulphur smell so that it can be detected.
Recommended for use with cars and small vans.
Is it possible to save using natural gas as fuel?
Yes, it is possible to save, because the cost per kilometre is 50% lower than a petrol vehicle and 30% lower than a diesel vehicle.
Average prices in 2019: Petrol price €1.29/l. Diesel price €1.21/l. LNG price €0.74/kg. CNG price €0.90/kg. Prices source: MITECO (the Spanish Environment Ministry)
Does the use of natural gas as a fuel offer environmental benefits?
Natural gas is a clean, safe and environmentally friendly fuel, reducing oxides of nitrogen (NOx) by 85% and eliminating 96% of solid particle (PM) emissions. It also helps mitigate the greenhouse effect by completely eliminating sulphur emissions and reducing carbon monoxide (CO) and CO2 emissions by up to 25%.
Natural gas engines also produce less vibration and noise, so the noise pollution produced is also lower.
What are the benefits of having the ECO label?
With the DGT’s ECO labels, discounts can be obtained on regulated tolls and parking. In the event of pollution episodes, the label also enables the vehicle to circulate in city centres.
How do I fill up with LNG and CNG?
What LNG and CNG vehicles currently exist on the market?
The major manufacturers offer a wide range of LNG-powered heavy vehicles and CNG-powered light vehicles.
The Gasnam catalogue contains all the natural gas vehicles on the market.
Are there grants for purchasing NGVs (natural gas vehicles)?
Yes, there are grants and subsidies for the purchase of this kind of vehicle.
How do you pay for LNG and CNG refuelling?
The Andamur ProEurope card is a convenient way to pay for LNG and CNG refuelling at our gas fuelling stations.
CNG can also be paid for using any bank card.
