Draft EN-1 establishes an urgent need for hydrogen and CCS infrastructure and, in contrast to the existing EN-1, makes clear provision for new and emerging technologies. Draft EN-4 makes clear that policies and strategies are currently being developed to assist in establishing the pipelines and infrastructures that would be required to fully support the requirements for hydrogen and CCUS. As the evidence base evolves, further guidance will be provided to allow timely implementation of policy relating to low carbon hydrogen, CCUS and other infrastructure necessary for the transition to net zero. No further amendments are required to draft EN-4 at this time.
