The Frisian islands are ideally suited for the generation of renewable electricity due to their natural conditions - and the production and use of green hydrogen on site is also increasingly becoming an important building block in the implementation of the energy transition. The H2Watt project aims to build a cross-border hydrogen economy that features advanced technological developments and knowledge transfer.

Current: Presentation of the project results on December 15, 2022.

Mariko GmbH invites you to let the Reveu project pass by on December 15 and to follow the project results. The event will be held in German and Dutch and via the Microsoft Teams system. Participation in the event is free of charge.

To the event and registration

The H2Watt project is being implemented primarily on the islands of Borkum and Ameland. Due to the natural conditions, the Wadden Sea offers optimal conditions for the production of green hydrogen, e.g. with the help of wind power and solar plants as well as by means of the energy from wave and tidal power plants. Due to the exposed location, the supply system can also be considered self-sufficient on the islands.

The project will analyse and test possibilities for the production, storage, transport and use of renewable energies and hydrogen. The ultimate goal is to develop and introduce market-oriented technologies for hydrogen applications. The project started in July 2019 and will run until June 2022.

H2BrakeCO2 -

Overall hydrogen concept for ports

In the H2BrakeCO2 project, an overall concept for the development of a hydrogen economy in the city of Brake and the surrounding northwest metropolitan region was created. The focus here is on port and logistics processes. The concept is intended to serve as a blueprint for the energy transition in other port cities.

The overall concept of the project funded by the Federal Ministry of Transport and Digital Infrastructure (BMVI) as HyExpert considers the production of hydrogen using renewable energies along the entire value chain up to its application. In particular, shipping and road transport were taken into account. Thus, through H2BrakeCO2, the city of Brake can act as a blueprint for a brake on the carbon-based transport economy and contributes to the sustainable design of port and logistics processes in the sense of "smart logistics". The project ran from July 2020 to September 2021.

Following the successful HyExpert project H2BrakeCO2, a hydrogen test field is to be established in the city of Brake with a focus on road freight transport and intralogistics in the port area. In addition to the testing of hydrogen trucks, further concrete steps are to follow with the preparation of feasibility studies for the conversion of handling equipment for which no series vehicles are available on the market today.
