Background and work of the University of Applied Sciences Emden-Leer

The use of hydrogen (H2) is regarded as a key element in shaping the energy turnaround.

Particularly in the north of the Netherlands and Germany, where renewable energy is increasingly being generated, the use of hydrogen as an energy carrier is becoming increasingly important.

The H2Watt project offers a platform for the realization of various innovation projects for the implementation of hydrogen. The focus is on processes and systems for the use of hydrogen in terms of production, storage, mobility and heating systems. The initial projects include a residential quarter, the Borkum island railway and a water taxi.


The University of Applied Sciences Emden/Leer is working on two thematic complexes in the H2Watt project. On the one hand, the model regions Borkum and Ameland are modelled. The production and supply chain of hydrogen in the Department of Engineering is examined, whereby the CO2 footprint of the entire process is illuminated.

On the other hand, the Department of Maritime Sciences is working on the design and implementation of a hydrogen-based range extender for a small maritime vehicle (water taxi). The project plan provides for the following activities in this implementation project:

  • Market research on available H2 technologies
  • Evaluation and selection of a suitable system in the power range 5-10 kW for a water taxi
  • Test setup and scientific investigation of the selected system in the new Maritime Technical Centre on the Maritime Campus in Leer
  • Evaluation of the results and, based on this, conception for testing the system in a real laboratory on board a water taxi



The H2Watt project is coordinated by Mariko and FME and is funded by the European Regional Development Fund (ERDF) and the State of Lower Saxony (Lower Saxony Ministry for Federal and European Affairs and Regional Development) as well as the provinces of Drenthe, Friesland and Groningen within the framework of the INTERREG V A programme Germany-Nederland. It is accompanied by the INTERREG programme management at the Ems Dollart Region (EDR).
