      • Discover the content of the session: "Distributing hydrogen from offshore wind farms as a fuel for ships"

      • There is a global interest for hydrogen as a complementary energy medium for industrial and mobility applications. In the offshore sector, coupling between wind farms and hydrogen production units is under active consideration. One key aspect of the on-going reflections is the production and distribution of hydrogen at sea. Offshore distribution of renewable hydrogen or ammonia, close to their production area, could be a great opportunity both for the wind industry and the shipping industry, optimising the supply of green energy for maritime transport. The purpose of this panel discussion is to explore the mutual benefits and challenges for the set-up of a network of offshore renewable hydrogen/ammonia filling stations.

        Abstract

         

        Presentation of an offshore distribution platform: SEAGUEL: Conceptual design of a bunkering station offering decarbonized fuels for ships

        (87) Sofresid Engineering, France

        In order to meet Worldwide commitment of the energy transition, a cleaned value chain in marine renewable energy shall be developed with the objective of reducing greenhouse gas emissions. Bearing this in mind, Sofresid Engineering focus on the development of the production and the supply of Green Hydrogen fuel from Offshore Wind Farm. In this context, in 2021, SEAGUEL, a Green Hydrogen Offshore Gas station, has been developed to refuel the maintenance boats of Offshore Wind Farm.

        The development of SEAGUEL is driven by multi-criteria:

        • Offshore Space limit: due to offshore location, space optimization is crucial for minimum impact and cost saving. Equipment is drastically chosen to minimize footprint and plant arrangement is optimised as much as possible.
        • Working force limit: This Gas station aims to be unmanned for ease to use and safety considerations. The system is controlled remotely, and spares of equipment are added.
        • Refuelling Time limit & Frequency: A constant weekly refuelling frequency must be maintained. The chosen equipment shall meet the set refuelling requirements in a timely manner.
        • Energy consumption limit: Energy consumption of the process needs to be optimized to impact at minima the electrical power from Wind farm.
        • Real Case Scenario: Only currently commercialized Hydrogen technologies available on the market were considered.

        This presentation will share lessons learnt from conceptual design engineering activities on SEAGUEL
