Transport and natural gas

Gas Networks Ireland is delivering the future of sustainable transport in Ireland

Compressed Natural Gas (CNG)

High emissions and the rising cost of transport has shifted focus from the traditional transport fuels of diesel and petrol to alternative fuels. Compressed Natural Gas (CNG) offers a solution to Ireland’s transport fuel needs

CNG is the same efficient and affordable fuel that is used to generate our electricity, heat our homes and cook our food. It is simply compressed to fit in the fuel tank of a Natural Gas Vehicle (NGV). CNG is a global alternative to diesel or petrol as a transport fuel. It has similar refuelling and operational characteristics to diesel, providing fast filling and similar travel ranges.


Natural gas is the most environmentally friendly fossil fuel available. The use of natural gas instead of more polluting fuels like diesel and petrol results in considerably lower emissions of climate changing greenhouse gases. The chemical properties of CNG compared to diesel contain significantly less polluting and harmful substances.

22% less CO2

70% less nitrogen oxide

99% less particulate matter

80% less sulphur dioxide

Cheaper by up to 35%

CNG can result in fuel cost savings of up to 35%, making it an extremely attractive alternative fuel source. The Irish Government’s Finance Bill has confirmed that a set excise duty of €9.36 per megawatt hour will be applied to CNG for the next 8 years, reflecting their commitment to promoting less polluting transport fuels. This makes CNG competitively priced compared to the fluctuating price of other fuels.

Proven and safe

CNG is a proven, reliable, and safe technology with over 19 million vehicles in operation worldwide. There has been strong growth in the developing European market recently with over 1.9 million vehicles in operation.

Quieter and quick to refuel

NGVs are quieter and experience less vibration than equivalent diesel vehicles. Their refuelling times are equivalent to that of other fuels such as diesel and petrol, so no long waits. It's also convenient as CNG is always available and never has to be stored or ordered.
