Due to its numerous benefits, LNG became a very attractive energy source for the European inland navigation sector. The full exploitation of LNG requires the development of a complete and favourable regulatory framework and a critical mass of investment in terminal infrastructure and LNG fuelled or LNG carrying inland vessels. In order to facilitate this development, Pro Danube Management and Port of Rotterdam initiated the LNG Masterplan, a project that addresses Priority Project Nr. 18 “Waterway axis Rhine/Meuse/Danube” of the TEN-T network. With 33 beneficiaries and more than 50 companies and organisations associated, the LNG Masterplan provides a powerful project platform facilitating parallel development of the necessary regulatory framework for LNG as vessel fuel and cargo and delivering initial deployment in terminal and vessel infrastructure.
