In its EU Hydrogen Strategy in July 2020, the European Commission highlighted that hydrogen is a key priority to achieve the European Green Deal and Europe’s green energy transition. The Hydrogen Strategy sets out a roadmap for building a hydrogen economy in Europe over the next decade. A key prerequisite for spreading the use of hydrogen is the availability of network and storage infrastructure to connect supply with demand. This will most likely include dedicated hydrogen networks alongside approaches of blending hydrogen into the natural gas network. European energy regulators (ACER and CEER) have published a set of recommendations on when and how to regulate pure hydrogen networks. The need and scope of hydrogen network regulation will depend on its structure and evolution.
