Based on a case study, this chapter explores the hydrogen innovation system in Norway, and it’s sectoral configurations. We explore the sectoral configurations by looking at how enabling, production, and use sectors are starting to make up elements of a hydrogen value chain and influence innovation system dynamics. By analysing dynamics, such as knowledge development and experimentation, we see activities clustered around certain sectors. These include the maritime user sector and two main hydrogen supply sectors (green and blue hydrogen), each with different enabling sectors (renewable electricity and natural gas coupled with carbon capture and storage), albeit with a focus on green hydrogen so far. Green hydrogen depends on a particular sectoral configuration with strong interdependence with the enabling electricity sector, with potential upscaling restraints. Exploring the sectoral configuration may thus help identify segments and interdependencies where key processes are developing well or where strengthening is needed.
