A pioneering hydrogen economy is emerging in Bremen. The “Office for Hydrogen and Climate Transformation in Industry” at the Senator for Economic Affairs, Ports and Transformation is the first point of contact for concerns in this field and is closely networking with all relevant departments and companies.

The Senator for Economic Affairs, Ports and Transformation has a wide range of responsibilities. Some of these relate to the office's role as a state ministry of the Federal State of Bremen (which consists of the two cities of Bremen and Bremerhaven), and some derive from it being part of the municipal administration of the city of Bremen.

The Senator for Economic Affairs, Ports and Transformation is also responsible for associated organisations, such as Bremeninvest.
