This thesis is an analysis of the implemntation of hydrogen in the Netherlands, in which the partnerships, organization and regulations are analysed from a Socio-technical transition perspective. The aim of this research was to find out how the implementation of hydrogen in the Netherlands has taken place and how this can be facilitated in the future. As an important aspect of hydrogen is cluster formation, this has also been taken into account in the research. Hydrogen cluster delineation is challenging, since they should have a focus not only on incremental innovations but also on radical innovations toward sustainability and often contain a mix of niche players and established regime actors. Additionally hydrogen has a plethora of end-uses, in a multitude of sectors/industries and on different scales. Therefore the clusters were delineated with the use of the proposed merged Technological Innovation Systems (TIS) and Multi-Level Perspective (MLP) framework from Markard and Truffer (2009). Once all niches that originate from the clusters were identified, these were analysed using the MLP and Strategic Niche Management (SNM), adapted to have more specific criteria. This research utilized a process perspective, which views reality in terms of a stream of events. More specifically the methodology of Event Sequence Analysis (ESA) was used, which provided specific tools for systematically identifying and comparing specific sequences of events. Primary data (from web pages, documents and news messages) was gathered through a specific data gathering process, defined by the ESA methodology, which was visualized as an event map. Secondary data from interviews were used as validation for the regular ESA. From the ESA spanning from the introduction of hydrogen as a sustainable energy carrier around 2001 until 2020, it has become clear that hydrogen implementation in the Netherlands has performed quite well from an internal niche perspective. Despite the high-quality internal niche processes across the board, implementation has been moderate due to the financial barriers that come with hydrogen, which can be attributed to the sheer expense of projects due to the niches’ infancy, the large-scale nature of the transition, with the infrastructural overhaul that needs to take place and some current legislative limitations, such as sub-optimal directives towards hydrogen-grid mixing. Next to this, there are three apparent patterns that can be identified. (1) Firstly, there is a clear succession of niches, meaning that there is a clear link between successive events which influence each other. (2) Secondly, there is a dependence on international collaboration, with most niche implementations being embedded within international (mostly European) initiatives and projects or have been subsidized by them. (3) A final pattern is the regional embedding of the implementation of most of the niches. This can be attributed to the large-scale nature of the transition and the dependence on synergistic implementations with dependence on supply to multiple sectors. To conclude, from the ESA it has become clear that the hydrogen transition is complex and needs active stimulation to become adopted more widely. This thesis suggests that the upscaling should be pursued with three main aspects in mind: (1) Firstly, it should be done within embedded regions, which are mainly formed in (harbor) clusters. (2) Secondly, the ESA proved that international collaboration is of essence in this transition. (3) Lastly, there should initially be a concrete focus on knowledge creation, due to the complexity of the transition, there is still a lack of knowledge with regard to the optimal implementation and a lack of educated personnel, which will all be pivotal for the success of this transition.
