The MvI project aims to implement and examine the onshore supply of electricity and hydrogen to watercraft alongside land vehicles. The primary goals are to advise on how supply units across modes of transport should be designed to achieve synergy effects, cut costs, and enable a transition towards alternative drive technologies especially for inland shipping. The study specifies the various users’ infrastructure requirements for onshore power supply and compiles possible configurations based on available grid expansion. For examining the infrastructure, the test platform ELEKTRA is used. Designed as a towboat, it has an accumulator capacity of approximately 2.5 MWh and carries 750 kg of hydrogen in exchangeable Multi-Element-Gas-Containers (MEGCs). It is equipped with various power connections to test new charging technologies (via Marechal, DC) as well as using established connections in shipping (CEE and Powerlock, both AC). This enables the infrastructure to be used by the ELEKTRA and other commercially used inland vessels. Charging capacities of up to 350 kW will be available. Evaluation of the supply infrastructure takes place in Westhafen Berlin and Lüneburg which will enable the towboat to perform tours to Hamburg. Furthermore, various scenarios for the supply of hydrogen are being studied. Those are, next to others, the use of MEGCs. Additionally, business models to ensure the supply of inland shipping with energy sources are developed. Aiming to describe how ownership of the infrastructure can be designed and the resulting corresponding economic perspectives.
