Ships could be refuelled with hydrogen generated as part of a wider plan to deliver renewable fuel to Norway’s offshore oil and gas platforms.

The Deep Purple project coordinated by oil services company TechnipFMC aims to convert windfarm-generated electricity to hydrogen which can be stored on the seabed and supplied to offshore facilities on the Norwegian continental shelf. TechnipFMC has appointed hydrogen power consultancy Hyon to deliver engineering services including technology qualification and subsea energy storage.

“In addition to powering offshore oil and gas installations, the hydrogen produced can also be used for zero-emission power onboard ships,” said Hyon managing director Tomas Tronstad.

Hyon’s scope of involvement also includes contributing its expertise in electrolysis, storage, and fuel cell technologies, as well as competencies within naval architecture and the design of hydrogen processes and power facilities for marine structures.

The Deep Purple project was conceived in June 2016 by partners including TechnipFMC, research institiution SINTEF and Bergen-based technology cluster Energy Valley. Developing technology that can store hydrogen offshore would remove challenges associated with storing the fuel on land -including perceived safety concerns - and pave the way for the use of the clean fuel at sea.

The news follows the unveiling of another ship refuelling concept that would rely on clean fuels generated from windfarm electricity. Partners in the Zero Emission Energy Distribution at Sea (ZEEDS) consortium – Wärtsilä, Kvaerner, Aker Solutions, Equinor, DFDS and Grieg Star - proposed a network of offshore bunker stations at Nor-Shipping earlier this week.
