The Hamburg metropolitan region exhibits a high density of hydrogen projects which are backed by a large number of individual companies and institutions, as well as company consortia. They are found not only in various sectors such as the basic and raw materials industry, the maritime sector, aviation, logistics, the mobility and the real estate sectors, as well as in research. They represent the entire hydrogen value chain, from production, distribution and transport to application. Many projects are in the planning and implementation phase, while others have been operating for many years and provide science and industry with valuable insight. New projects will continue to join them in the near future, which is why we are constantly expanding the website.
