Compressed Natural Gas (Cng)

CNG (Compressed Natural Gas) is an alternative fuel for cars, trucks and buses. Unlike LPG (liquefied petroleum gas), it is composed of methane and not of propane and butane.

Thanks to a long-established and cutting edge technology, Italy is the first European market for natural gas for vehicles, with almost 1 billion cubic meters consumed in 2019 and about 1 million vehicles currently in circulation.

Outcomes

Using CNG as a fuel has many advantages over traditional fuels.

From an environmental point of view CNG vehicles would reduce emissions of CO2 by about 33%**, nitrogen oxides by about 75%*, and particulate matter by about 97%* with respect to the vehicles replaced, thus significantly lowering emissions.

Investing in natural gas as an automotive fuel would have major economic repercussions on a national level and let both families and business save money.

 

Car Compressed Natural Gas (CNG): the most immediate and effective response to environmental pollution

Pollutant emissions:
the worst enemy

• Italy among the most polluted EU countries
• 66.000 premature deaths engendered by pollutant emissions (436,000 in the EU)
• 100 billion euros of annual expenditure for health issues

the solution

 

Environmental benefits

• -97%* PM
• -75%* NOx
• -33%** CO2

Savings

Up to 800 mln € in 5 years

Snam believes in CNG as an alternative fuel for road transport and promotes a series of initiatives to foster the use of CNG on an even larger scale. For this reason Snam will invest around 100 million euros over the next years to facilitate CNG-refueling-plant development. This will increase the number of existing gas natural stations, improve service quality, and ensure a more balanced distribution of stations througout the country.

Among most relevant initiatives there are:

• cooperation agreement with Landi Renzo to boost the development of natural gas mobility in Italy
• Tamoil and Snam for sustainable mobility: contract signed for 5 new natural g as service stations
• partnership between SEAT and Snam to promote the use of natural and renewable gas for cars in Europe
• framework agreement with Eni for the development of methane gas stations in Italy.
• letter of intent with Api Group for the development of methane service stations across Italy
• memorandum of understanding with FCA and Iveco for the development of natural gas as an environmentally friendly vehicle fuel

CNG's economic benefits

A further development of CNG for vehicle usage will produce a direct benefit of 1.5 billion euro for Italian produced natural gas technology and more than 1 billion euro in overall infrastructure investments for the development of CNG filling stations, with significant benefits also to employment. Consumers will also enjoy overall savings estimated at up to 800 million euro in five years' time.

Gas mobility is a sector in which Italy is the absolute leader in Europe, with the infrastructure network - the one managed and developed by Snam - the most widespread of the entire continent and the largest number of gas cars and distributors that supply it. The sector has a total of 6 thousand workshops and, between direct and indirect related industries, employs over 50 thousand workers.

Energy for the future

Providing Italy with natural gas infrastructure and technologies engenders further positive outcomes: for instance, it fosters biomethane, a fuel with a footprint similar to the electric. In detail, it may promote an increase in domestic production of gas with positive effects on the agro-food sector, as biomethane is obtained from the processing of agricultural and agro-industrial by-products.
