Vehicular natural gas (CNG), the electric alternative


At a time where alternatives to traditional fuel are being sought for environmental and economic issues and where sustainable mobility prevails above all else. We present you natural gas for vehicles.

Most of the population thinks that there is only diesel or gasoline to refuel the car but, even if you have never heard of it, there is an alternative to traditional fuels: vehicular natural gas (CNG). In this post, we explain what it is and how it works.

Faced with this new paradigm, vehicular natural gas is gaining strength as an alternative to diesel or gasoline. Because, as you will see later, all are advantages and it is very respectful with the environment.

What is and how does vehicular natural gas work?

But what exactly is vehicular natural gas? It is a type of alternative fuel to the use of diesel in cars, less polluting. It is a solution to the problem of pollution in large cities. Much more economical, efficient and sustainable than gasoline and diesel. It is a good bet for the future. We are experiencing an important energy transition that is directed towards decarbonization, and where gas appears as the most profitable, efficient and sustainable solution as an intermediate step towards the electric car and sustainable mobility.

Its operation is very simple. Gas burns inside engine cylinders, just like gasoline burns. The result of this combustion is thermal energy that is released and transformed into kinetic energy that turns the wheels of the car.

Types of vehicular natural gas: LPG and NGV

There are two types of gas for use by vehicles:

CNG: it is compressed natural gas, in a gaseous state, but under pressure. It is mostly used for cars and vans.

LNG: it is liquefied natural gas (at a very low temperature and natural gas becomes liquid). It is less known and is used only for buses and trucks.

It is normal that everything sounds to you as if it were a science fiction movie because in Spain it is hardly used. However, gas stations have already begun to be built as the necessary infrastructure to be able to refuel your car with gas.

What are gas stations?

Cars that use gas as fuel, refuel practically the same as gasoline or diesel. The service stations that supply gas to cars are known as “gas stations”.

Gas stations are distribution service stations for CNG (compressed natural gas) and LNG (liquefied natural gas). The former refuel passenger cars and light vehicles, while the latter facilitate the service of heavier transports.

At the moment, in Spain there are 57 vehicular natural gas stations open to the public. The forecast is for there to be almost 100 before the end of this year. Also, 6,100 vehicles equipped with this technology are expected to circulate.

What are the advantages of using vehicular gas?

Here are some interesting facts about the use of natural gas in vehicles. First, it reduces nitrogen oxide (NOx) emissions by almost 80% and sulfur oxide (SOx) emissions by practically 100%. In addition, it reduces 95% of the emissions of particulate matter in suspension.

Also, car engines produce half the noise and vibrations and emit 20% less CO2 into the atmosphere. And, in case you are not yet convinced, the use of natural gas reduces noise pollution by 50% compared to diesel engines.

The future of vehicular gas use

In case you didn’t know, the demand for vehicular gas grew 10% last year. And according to different forecasts, it is estimated that, in the medium term, between 25 and 50 percent of diesel engines will be replaced by engines that use natural gas as fuel. This will undoubtedly help reduce CO2 emissions and noise pollution.

In Europe, there are already 70,000 urban buses that use vehicular natural gas. And, by 2020, the countries of the European Union must have CNG (compressed natural gas) service stations installed every 150 kilometers and LNG (liquefied natural gas) every 400 km.

In SP Solar We are currently energetic and we have 2 of our own gas stations located in the center of Madrid.
