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, several factsheets providing basic information on innovative technologies in modernising inland vessels are released.

A technological innovation factsheet about fuel cell propulsion was newly elaborated in the framework of GRENDEL in cooperation with the INDanube Innovation Transfer Centre.

This factsheet offers insight into various applications of fuel cells for propulsion and auxiliary power in inland ships. Hydrogen storage options and alternative energy carriers are presented with their pros and cons in brief. Information ranges from relevant regulations, technical concepts including benefits and downsides to recommendations for further reading.

The following factsheets addressing fleet modernisation aspects were already elaborated:

• Modernisation of Danube inland vessels
• Gas and Gas-Electric Propulsion
• Diesel Electric Propulsion
• After-Treatment
