GRENDEL Green and efficient Danube Fleet

IWT Innovative Technologies Database


	introduction

The core objective of the GRENDEL project is to give a lasting impulse to the modernisation process of the Danube fleet. With the Danube being considered as the economic backbone of a region that comprises 10 different European countries, adapting its severely outdated inland fleet to the needs and requirements of a future oriented transport system is an endeavour that must go beyond borders. Efficiently integrating IWT to the transnational transport and logistic chains will have a positive impact on the overall socioeconomic development of this region.

Even though IWT is considered as one of the most environmental-friendly modes of transport, it is by far not exploited at its full potential. The reasons for this are manifold. Since the Danube Region is primarily characterized by less developed regions, vessel operators usually lack the necessary financial capacities to properly invest in their fleet. Moreover, the findings of GRENDEL have shown that there are currently no financial incentives available at the national level that would encourage the greening of the Danube fleet. The IWT sector is furthermore characterized by the relatively slow incorporation of innovative technologies as compared to other modes of transport.

The aim of this Innovative Technological Database therefore is to centrally collect valuable information on greening technologies. It provides both a general overview as well as - based on the provided documentation - an in-depth analysis of the existing innovation rate and its potential to be efficiently implemented in IWT.

This database is in particular built on the know-how gathered in the framework of the GRENDEL project, taking into account the developed technological factsheets and the organised know-how transfer events, thus focussing on topics relevant for the Danube fleet. Some presentations were also collected from the workshop on the modernisation of the Danube vessels fleet organised by INDanube together with the PROMINENT (H2020) and the GREEN DANUBE (DTP) projects in Vienna (Austria) on 18 April 2018, from the First LEC Sustainable Shipping Forum organised in Graz (Austria) on 26-27 September 2019 and from the Green Inland Shipping Event organised in Brussels (Belgium) on 16 October 2019.

The database was regularly updated until the end of the project, also integrating the vessel concepts developed by GRENDEL fleet operators (NAVROM/SDG, FLUVIUS, DANUBIA).
