7.5 Gas in the transport sector

The current state of gas in the transport sector is covered in the Demand chapter, along with the alternative fuel initiatives that are being implemented. In addition, the Energy Transition chapter raises the potential for the further benefits that could be seen from the increase in the amount of renewable gases in the transmission system. Gas infrastructure can support new filling stations and LNG bunkering facilities, which will enable the supply of gas as an alternative fuel for transport in a variety of forms. This represents energy transition in the transport sector, by providing a lower cost option for consumers but also fulfilling long distance and heavy goods vehicles (HGV) requirements, and does not compete with the electric vehicle development. Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG) are technologies that are necessary, among others, to substitute oil as the dominant energy supply for transport. They are mature technologies and only lack the related refuelling in- frastructure level to enable mass exploitation. In the particular case of CNG and LNG, progressive results can be achieved in emissions reduction when combined with the renewable gases also described in this chapter. For light duty vehicles, CNG engines produce fewer emissions (CO ² , NO x , SO x …) than from oil engines and their consumption is proved to be economically competi- tive versus diesel. In large population areas with heavy traffic problems, issues like particle and noise pollution could also be improved by promoting this technology, while in long distance roads it offers higher autonomy than electric vehicles. Additionally, for heavy duty vehicles and fleets, LNG is a clean, non-toxic technolo- gy that can extend the life of the vehicle longer than other engines and also requires less servicing.

4.5.1 CNG AND LNG

4.5.2 MARITIME

LNG in maritime transport offers a clear advantage especially for both construction and conversion of ships in the focus of emission regulations. Conventional oil-based fuels are currently the main fuel option for most vessels, however offer limited po- tential to comply with air emission limits through the installation of additional process technology. LNG technology is the only option that can meet existing and upcoming requirements for emissions  1) .
