Frequently Asked Questions about: Methane (CNG)

CNG is natural gas (methane), which is lighter than air, whereas LPG (Liquefied Petroleum Gas) is a mixture of propane and butane, which is heavier than air. CNG is stored in tanks under high pressure, while LPG is stored in a liquid state under lower pressure. CNG is considered more environmentally friendly and is often more affordable.

CNG is usually significantly cheaper than gasoline and diesel. The specific savings depend on current prices, but users often report savings of up to 30-50% per kilometer driven.

Yes, it is. CNG burns cleaner than traditional fuels. It produces significantly fewer CO2 emissions and almost no particulate matter (PM) and sulfur dioxide (SO2), which makes it an excellent choice for reducing pollution in urban areas.

 It is stored in steel or composite cylinders (tanks) under high pressure (around 200 bar), typically located in the trunk or underneath the vehicle.

Modern and high-quality CNG systems are designed so that the power drop is minimal or unnoticeable during normal driving.

It is very safe. The cylinders and systems undergo rigorous testing. Since methane is lighter than air, in case of a leak, it quickly disperses, unlike LPG, which remains near the ground.

Maintenance is similar, with mandatory periodic inspections (certifications/recertifications) of the CNG equipment in accordance with legal regulations.

The range depends on the size of the installed cylinders. Converted vehicles are always bi-fuel (they use both CNG and gasoline), meaning that combining both fuels achieves a significantly greater total range compared to standard vehicles.

Unlike LPG vehicles, most countries (including Serbia) permit CNG vehicles to park in underground and enclosed garages. This is because natural gas (methane) is lighter than air, and in the event of a leak, it quickly dissipates towards the ceiling, making the risk significantly lower than with LPG, which remains near the ground. Nevertheless, it is always advisable to check the local regulations of a specific parking facility.
