Offshore Energies UK (OEUK) has published a report ‘An Integrated and Resilient North Sea’. It examines how the North Sea could develop into a coordinated cross-border energy system linking carbon capture and storage (CCS) and hydrogen infrastructure to support Europe’s net zero transition. The report states rising energy security pressures, decarbonisation targets and investment demands require a system-level approach to infrastructure planning. It warns that fragmented development could undermine scalability and resilience, and assesses CCS and hydrogen networks across the UK, Norway and mainland Europe. It considers technical, operational, regulatory and economic resilience, including interoperability, emissions trading alignment, cross-border rules, financing, underuse and long payback periods. It concludes that coordinated planning is needed to reduce costs and unlock regional value.
