Energy source and economic engine
Bremerhaven has already established extensive scientific expertise in the field of "green" hydrogen, spanning nearly all local research institutions and companies. Over recent years, a wide range of project experience has been gained, for example in the production of green hydrogen from wind power and the deployment of hydrogen-powered buses in urban transport.
These activities create new applications and business opportunities for local companies, while making Bremerhaven an attractive location for Green Economy ventures from outside the region. The BIS contributes to this development through its Regional Hydrogen Management, supporting the establishment of a hydrogen economy in Bremerhaven. The city’s activities are coordinated and integrated to ensure a unified approach.
A competence center for hydrogen applications has been established in Bremerhaven on the basis of scientific expertise and know-how in hydrogen and fuel cell technology.
The focus here is on mobile applications on land and at sea with expertise along the entire value chain. The players are in constant exchange.

The Hydrogen Lab Bremerhaven (HLB) focuses on the innovative combination of wind turbines and electrolytic hydrogen production in order to meet the challenges of decentralized power grids, particularly in the area of offshore wind farms. Funded by the state of Bremen and the EU, the HLB is testing electrolysers with a total output of up to 10 MW on ten test fields, which are supported by an 8 MW wind turbine installed on site. Another focus is the promotion of a local hydrogen economy through the integration of hydrogen production, storage and use, including applications in the food industry and the production of synthetic natural gas.

The research project IBOH2P aims to analyze the economic viability of various concepts for hydrogen production at offshore wind energy installations in the German North Sea and Baltic Sea. For the first time, real operational data from megawatt-scale electrolyzers will be incorporated into the analysis.
The study covers the development of production capacities, operational strategies, maintenance measures, and the associated offshore logistics processes. Innovative reliability models for emerging hydrogen production technologies will be developed and applied within simulation environments.
Repair and maintenance routines will be tested at the Hydrogen Lab Bremerhaven and adapted for offshore operations. These models will then be integrated into operational phase simulation models, enabling direct modeling of different locations and operational strategies.

Hydrogen energy system for autonomous offshore measurement stations.
The HydrASys project aims to develop an innovative hydrogen-based energy system specifically designed for autonomous offshore measurement stations and platforms, with the goal of replacing the currently widespread diesel generators in support of the decarbonization of the offshore industry.
To this end, the project consortium will first develop an innovative underwater storage tank based on metal hydrides, optimized for offshore conditions. Particular emphasis is placed on scalability, enabling a wide range of applications from small floating measurement buoys to large offshore platforms. As the direct use of hydrogen in the offshore industry is still not widely established, existing barriers will be addressed through certification of the overall system.
Furthermore, as a proof of concept, one of the LiDAR measurement buoys developed by Fraunhofer IWES will be equipped with such an energy system and extensively tested under real offshore conditions.

The Hanseatic Hydrogen Center for Aviation and Maritime (H2AM) aims to establish testing capacities for the development of hydrogen and fuel cell–based propulsion applications for aircraft and ships at its Northern German locations in Bremen/Bremerhaven, Hamburg, and Stade. The center also facilitates associated research and development activities in these fields.
H2AM evolved from the working title of the Innovation and Technology Center for Hydrogen Technologies (ITZ) and represents an initiative launched in June 2020 as part of the Northern German Hydrogen Strategy, initiated by the Federal Ministry for Digital and Transport (BMDV).
In Bremerhaven, the H2-3D Test Facility (also known as the Wave Simulation Platform) is being developed to provide infrastructure for testing hydrogen components and complete systems suitable for maritime applications in a three-dimensional environment.
The H2-3D Test Facility, together with the specialized expertise of ttz Bremerhaven, is designed to support companies active in the shipbuilding sector—particularly suppliers—in the development, testing, and validation of hydrogen and fuel cell–based components and propulsion systems for seagoing vessels. The testing infrastructure is especially intended for use by small and medium-sized enterprises (SMEs) as well as start-ups in Germany within the framework of research and development projects. It aims to help them bring innovative ideas and technologies to the international market and thereby contribute to Germany’s technological leadership in the hydrogen sector.

The use of hydrogen as a propulsion energy source—particularly in mobility, logistics, and maritime transport—still faces a gap between public expectations and current technological feasibility. Research, development, and testing in this field are therefore urgently required to enable the sustainable and economically viable production and use of hydrogen.
With its extensive expertise in mobility, logistics, and maritime industries, Bremerhaven offers ideal conditions for testing hydrogen-powered vehicle prototypes. The city is planning to establish an infrastructure for long-term testing under real-world conditions. This will include laboratories, workshops, a technology center for demonstration plants, as well as test benches and measurement systems. Existing vehicle workshops and shipyards will be converted for the maintenance of prototypes. In addition, software tools for system simulation will support product development and system integration.
The test region will sustainably promote the development of components and systems for mobile hydrogen applications up to market readiness. It will play a key role in accelerating the scale-up of hydrogen technologies in Germany and in strengthening both system suppliers and the component manufacturing industry.
Since January 2023, the Bremerhavener Versorgungs- und Verkehrsgesellschaft mbH (Bremerhaven Bus) has been operating three fuel cell solo buses in regular public service. The fleet was expanded in summer 2023 with four additional solo buses, and in 2025, three articulated fuel cell buses were added. All ten vehicles are fueled with green hydrogen produced locally in Bremerhaven.
The project is supported through the Hyways for Future initiative.
Since 2025, Bremerhaven has been home to its first public hydrogen refueling station, located in close proximity to Bremerhavener Versorgungs- und Verkehrsgesellschaft mbH and easily accessible via the A27 motorway exit Bremerhaven-Mitte. The station operates using locally produced green hydrogen generated from wind energy in Bremerhaven and is designed to refuel buses, trucks, and passenger cars.
HY.City.Bremerhaven GmbH & Co. KG produces green hydrogen within the city area using an electrolysis plant with a capacity of up to 2 MW. The hydrogen is supplied to the refueling station via a trailer exchange system.
The project is supported through the Hyways for Future initiative.
Research, development and innovation projects in hydrogen and fuel cell technology are interdisciplinary and directly linked to renewable energies and sector coupling. The various federal ministries offer funding programs with different priorities. The classification of projects within the funding framework must be specifically coordinated in each case.
NOW GmbH, on behalf of the German Federal Government, drives the development of hydrogen and fuel cell technologies as well as e-mobility. Its core responsibilities include coordinating and managing the National Innovation Program (NIP), supporting and overseeing funded projects from initiation to completion, and promoting research, development, and public acceptance of these technologies.
Almost all funding programs of the state of Bremen and BIS are not focused on hydrogen and fuel cells or the energy transition. In principle, all investment, innovation and environmental funding programs can be used for hydrogen projects.
Additional funding opportunities are provided by the Federal Government’s “Research and Innovation” funding advisory service.
