GRENDEL Green and efficient Danube Fleet

Long service life of inland vessels, high investment costs, low re-investment capacity of the Danube fleet operators together with knowledge deficits about green technologies as well as the lack of public actions & incentives impose severe barriers for the adaption of the Danube IWT fleet to forthcoming European IWT and environmental policy objectives.

The GRENDEL project supports the Danube vessel fleet operators and their public counterparts in modernisation of the sector. GRENDEL addresses various fleet modernisation aspects: [i] use of low carbon & alternative fuels, [ii] reduction of air pollutant emissions (CO2, NOx, PM) and [iii] overall energy consumption. Besides this, [iv] transport & logistics management processes are addressed to ensure better integration of the Danube IWT into logistics chains through new services (including River Information Services), digital data provision as well as dedicated tools to improve efficiency of fleet operations.

The project's overall goal is the improvement of the environmental and economic performance of the Danube fleet. This will be achieved through three specific objectives:

  1. Know-how transfer for Danube fleet operators with the help of intensive transnational collaboration between private & public stakeholders and targeted know-how transfer activities in order to overcome the existing knowledge gap, lack of activities and absence of instruments to deploy innovative solutions
  2. Elaboration of innovative technical vessel concepts and improved transport & logistic management processes of fleet operators and sharing these as good practices for wide-scale implementation to strengthen the competitive position of inland navigation and to exploit its market potential
  3. Supporting development of favourable regulatory framework & well-designed public support measures by  introducing Model State Aid Scheme & innovative financial instruments to design national public support measures which will clearly address the needs of the sector

With its activities, GRENDEL aims to achieve a higher acceptance and use of inland waterway transport (IWT) as an environmentally friendly transport mode contributing to economic growth and a more sustainable transport system in the Danube region.
