In the framework of the GRENDEL project, first factsheets regarding the potential of innovative technologies in modernising inland vessels were released in cooperation with the INDanube Innovation Transfer Centre.

As one of the main objectives of the GRENDEL project is to raise the environmental performance of Danube inland vessels and to fully integrate them in the transnational transport and logistics chains, a series of factsheets providing basic information on innovative technologies was recently released. The factsheets address the following fleet modernisation aspects:

• Modernisation of Danube inland vessels: this factsheet offers a comprehensive overview on the structure, type and age of the Danube vessels. Furthermore, it lays out the major environmental challenges currently faced by inland vessels in the Danube region.

• Gas and Gas-Electric Propulsion: LNG (liquefied natural gas) has the potential to significantly reduce the overall energy costs of ships. Moreover, LNG proves to be a feasible alternative to other types of fuel as it complies with air emission limits set by the European legislator. The factsheet provides basic information on technical, equipment and special safety requirements that go along with this reliable, clean and efficient type of ship fuel.

• Diesel Electric Propulsion: the factsheet offers insight into the potential of diesel electric propulsion in lowering emissions and provides information on its environmental and economic sustainability.

• After-Treatment: finally yet importantly, as the objective of the European Union is to firmly reduce the emissions of new engines being brought on the market and, thereby, to replace the old ones, the so-called Stage V EU Regulation enforces more stringent limits to pollutant emissions. Therefore, this factsheet offers comprehensive information on innovative after-treatment technologies.
