This paper investigates how existing technological and production capabilities can support the emergence and growth of green hydrogen value chains in Northern and Western Germany. Drawing on evolutionary economic geography, we argue that the development of the hydrogen value chain depends on the relatedness between existing knowledge bases and hydrogen technologies, and further recombinant capabilities, as well as the processes involved in acquiring capabilities. Our analysis focuses on seven NUTS 2 regions with favorable conditions for the development of hydrogen hubs, which are low cost of renewable energy production, access to hydrogen infrastructure, and political support for the hydrogen economy. We comparatively examine the regional capabilities using patent data to map technological innovation, firm-level data to identify key corporate actors, and regionalized export statistics to assess production capabilities. Based on our findings, we argue that the development of green hydrogen hubs might be facilitated by alignment between a region’s existing innovation capabilities, production capabilities, and hub specialization, with place-based policy approaches tailored towards each region’s unique profile.enhttps://creativecommons.org/licenses/by-nc-nd/4.0/Green hydrogenValue chainsRegional capabilities300 Social Sciences::330 EconomicsText::Buch10.26092/elib/4445urn:nbn:de:gbv:46-elib226721
