In recent years, Portugal has implemented an energy policy based on improving energy efficiency and promoting energy from renewable sources as a tool to address climate change, reduce foreign energy dependence and contribute to security of supply.
To this end, the Portuguese Government defines the minimum requirements for the deployment of alternative fuel infrastructures, including, among others, CNG compressed natural gas refueling stations, to be defined through the mandatory adoption of national policy frameworks, as well as common technical specifications for such refueling points and information requirements for users.
Thus, this National Action Framework includes an assessment of the current situation and future evolution of the alternative fuels market in the transport sector in Portugal and the development of the planned infrastructures, taking into account, where appropriate, cross-border continuity, and national objectives and targets will be defined for the creation of such infrastructures, specifically in the field of natural gas, as well as the necessary measures to ensure their fulfillment.
The use of natural gas vehicles, CNG, can offer both economic and environmental savings. The cost associated with natural gas is significantly lower than conventional fuels (diesel and gasoline) and, due to its characteristics, it provides clean combustion. At the environmental level, compared to traditional fuels, the emissions associated with this alternative fuel are also lower. Thus, in recent years a legal framework has been defined in Portugal aimed at promoting the use of natural gas as an alternative to conventional fuels for the transport sector.
The infrastructure for the supply of natural gas vehicles in Portugal is still under development. At the end of 2015, there were 6 CNG refueling stations available to the public, 4 of which also allow the supply of LNG.
Today the development of the network of CNG refueling stations in Portugal has developed maintaining a constant growth although the number of supply points is still scarce compared to other European countries
