Methane

CNG can be found only on petrol station 1184, Sofia. 

CNG or compressed natural gas is a traditional source of energy in the car industry. The CNG is low in pollutants, rich in calories and energy, economical and readily available worldwide.

Among the reasons to switch to CNG are:

• Low prices: The price of CNG is almost a third of that of gasoline in terms of calorific value, which leads to an increase in fuel costs, and the investment in CNG equipment pays off over time.
• Ecologically clean: Emissions of carbon dioxide are reduced from 70 to 90%, and of hydrocarbons from 40 to 60% compared to vehicles that use conventional fuel.
• Flexibility and ease of use: The vehicle can run on either petrol or CNG only by pressing a switch on the dashboard.
