While energy production (the energy sector) has undergone huge efforts to reduce greenhouse gas emissions, transportation and heating are next to be tackle. Hydrogen could be a solution for one of them, the heating sector. This chapter focuses on the Netherlands as a case study to investigate the (absent) legal framework and the regulatory challenges that the development and deployment of hydrogen in the heating markets face. After an overview of the EU regulatory framework, it delves into the specificities of Dutch legislation. The Netherlands is a suitable object of study because it has instituted concrete initiatives from which the energy supervisor, the Authority for Consumers and Markets (ACM), has created a temporary framework. The analysis reveals significant gaps and inconsistencies in the regulatory landscape and offers concrete suggestions for sector-specific regulation. In addition, the chapter discusses the implications of the regulatory framework for market participants and their behaviour, as well as the role of competition law and potential sector-specific rules in ensuring a level playing field for all market actors. The Dutch experience could potentially generate a model that other EU Member States could follow.
