Progress update

The development of the offshore renewable wind energy of the North Sea is central to the UK Government’s Net Zero strategy. Thanks to the advancement of electrolysis technology, green hydrogen is key to transporting renewable energy, from offshore wind to onland end users. 

The Hydrogen Highway project aims to design an offshore, green hydrogen system as a terminal, which integrates hydrogen production, storage, and offloading modules on a centralised offshore platform. 

The key findings of this work are: 

  • Two designs have been proposed to meet the offshore hydrogen demand in the UK for England and Scotland.  
  • The modularised design with add-on units, adopted for the offshore hydrogen system, enables excellent scalability. 
  • Compressed gaseous hydrogen is the best, current form in which to store hydrogen for production and transport. 
  • Hydrogen tank container design in the offloading process can use existing land-based infrastructure and a crane will make transport effective and economical. 
  • Expected ports for the offshore hydrogen transport have existing renewable energy development zones, e.g., Port of Aberdeen.  

The centralised offshore hydrogen system with modularised design creates a seamless land-sea interface for offshore renewable energy transport.  

The above outputs mark the successful completion of this associated Work Package research.
