Legal framework: permissions and restrictions (and Ownership constraints (unbundling))

This LAP concerns the injection of hydrogen into the gas grid at the TSO level and the legal framework status covering authorised bodies and varying hydrogen concentration levels in the TSO transmission system along with potential changes to the regulatory framework to support enhanced hydrogen injection and utilisation

The existing national legal framework for the DSO to carry out hydrogen activities, which is normally restricted to natural gas. Ownership constraints refer to the constraints related to ownership associated with the process of injecting.
