This project’s common challenge concerns the definition of an integrated LNG distribution system in the 5 partner areas, in whose ports the availability of LNG resources and storage sites is currently inadequate to supply watercraft and means of transport. The general objective is to deal with these shortcomings by developing plans and strategies to support the implementation of Directive 2012/33/EU and to assist areas where there are few or no methanisation networks. This will transform the opportunity offered by LNG into added value and reduce polluting emissions from industry and transport sector within these areas. SIGNAL develops the following: 1 maritime network optimisation model to supply LNG in the 5 areas involved; 1 storage site location model in the ports of destination; 1 internal distribution model for the weaker areas involved. The partnership will develop its activities in a synergistic and participatory way and exploit individual potentials for the benefit of a more complex and efficient integrated system involving the entire area of cooperation. The innovative element of the project lies in the methodological approach for defining plans and strategies, as well as in the role assigned to the ports as hubs to promote LNG use. The ports are places of maritime and land vehicles and of LNG storage and use as well as access doors for LNG distribution in the area. In the cross-border cooperation area, planning a port and coastal system of storage and regasification plants will support the strategic development of the LNG distribution system; a fundamental factor for cost-effective and efficient delivery of LNG to end users.
