Mitsubishi Heavy Industries (MHI), Shell, Wärme Hamburg have signed a letter of intent to plan how they can jointly produce hydrogen from wind and solar power at Vattenfall's Moorburg power plant site in Hamburg and utilize the hydrogen in its vicinity. In addition to the construction of a scalable electrolyser with an initial output of 100 megawatts, the further development of the site into a so-called "Green Energy Hub" is planned. This includes the exploration of the extent to which the existing infrastructure of the Moorburg location can be used for the production of energy from renewable sources.

In this context, concepts for the necessary logistics chains and storage options for hydrogen will also be considered. Subject to future investment decisions and according to the current state of planning, once the site has been cleared the production of green hydrogen is anticipated in the course of 2025. This would make the electrolyser one of the large plants in Europe.

In their efforts to form a consortium, the four companies can also count on the support of the City of Hamburg's government. In their coalition agreement, the governing parties agreed to examine and support the feasibility of sector coupling and the establishment of hydrogen production in the city-state.
