This study tries to answer two fundamental questions related to the introduction of hydrogen in the Netherlands’ energy system in the period until 2030: what is the likely order of magnitude of electrolyser capacity investment in the Netherlands and what are their main drivers; and given such investment, and given the different sizes of electrolyser installations (varying from a scale of some MWs to GW-scale), where will those investments most likely be located and what are the most likely drivers of the choices of location? Both questions are highly relevant for the TSO and DSO’s responsible for hydrogen transport. The more hydrogen will be produced domestically as opposed to imported via the main harbours, the more transport capacity will need to be developed to service the market. The better the understanding of where hydrogen production will most likely be concentrated, the better the TSO but the DSO’s in particular will be able to plan their future hydrogen related transport capacities.
