The HYSHORE project is part of the global strategy to decarbonise the economy and to search for new alternative energy vectors to fossil fuels.

The focus is on the field of hydrogen and its “green” generation by means of offshore wind renewable energy, by addressing different technical challenges that the industry is facing related to the transport and logistics of hydrogen generated by the wind farms.

The Basque Country is conducting numerous initiatives to drive the activity in hydrogen technologies. These include:

  • The Basque Maritime Forum has deployed a specific strategic line of action for hydrogen and seeks to implement projects in the maritime sector that address the environmental challenges and develop technologies in the field of hydrogen to meet those challenges and to place the Basque maritime industry in a leadership position that enables our companies to generate wealth and employment.
  • “The Basque Hydrogen Corridor – BCN2” initiative, drive by Petronor, was set up in 2020.
  • Bizkaia Provincial Council and Petronor have set up the “Basque Hydrogen Hub” to drive industrial and technological development around hydrogen and help in the decarbonisation of industrial processes and mobility.
  • A unit dedicated to hydrogen has been set up at the “Energy Intelligence Center” (EIC)2 and the “Hydrogen Living Lab”, in the Abanto Technology Park.
  • The RIS3 Energy Pilot Group has agreed to include the field of hydrogen as a new Energibasque strategic area and which joins the 8 existing ones.

Description of the project:

The HYSHORE project addresses the technological research and development by Basque companies of different sectors in an important part of the hydrogen value chain, including the transport and logistics of the green hydrogen generated by offshore wind farms. Technological solutions will be developed in the fields of materials, components, systems and their manufacturing processes linked to the different technology problems existing in this field.

Goals of the project:

 The primary purpose of the HYSHORE project is to drive and strengthen the capabilities of the shipbuilding, offshore renewables, oil & gas (in its transformation process) industries, and the new hydrogen industry, of the Basque Country. This aim consists of developing new technological solutions (materials, manufacturing processes and means, components and systems), for applications in the transport and logistics of the hydrogen generated by offshore wind farms. Two channels are envisaged: pipeline and by boat.


The research conducted in conjunction with the consortium companies will be used to develop technological solutions that optimise the average total costs of constructing and operating floating wind power facilities with transport of hydrogen to shore, during their service life.


Thus, apart from the initial costs of the systems, the operational aspects and their associated costs throughout their service life, which will be over 25 years, shall also be taken into account.

Green offshore energy

Green hydrogen through offshore wind farms

Transport technology

Tubular solutions for the offshore transport of high pressure hydrogen development

Hydrogen storage

Development of high pressure tanks to transport hydrogen in vessels

Materials analysis

Study of the behaviour of HYSHORE products and validation of prototypes

Phases of the project:


Requirements, Specifications, Legislation, Safety

The aim is to define the requirements of the compatible products in order to obtain solutions for transporting offshore hydrogen.


Offshore Hydrogen Adaptation and Management

Research and technological development of the equipment and systems needed for the adaptation, storage and handling hydrogen in different formats (compressed hydrogen and ammonia) for its maritime transport and by underwater hydrogen pipeline.


Research and development of Manufacturing Materials, Processes and Means

Two main tasks will be undertaken. On the one hand, the development of new materials and protection solutions for extreme conditions (marine and hydrogen) and, on the other hand, development of manufacturing processes compatible with those new materials and the appropriate manufacturing means.


Design and manufacturing of new product, process and service prototypes

Prototypes will be researched and developed for the two ways of transporting hydrogen: pipeline and by boat:

  1. Materials for high-pressure hydrogen offshore transport pipes
  2. Pipes for offshore transporting hydrogen at high pressure
  3. Manufacturing technology to produce bi-metal pipes as a solution for the offshore transporting of hydrogen at high pressure
  4. Process to weld pipes for offshore transporting hydrogen at high pressure
  5. Connectivity for transporting hydrogen
  6. Type III tank design and prototype of critical zones
  7. High-pressure hydrogen compressors (950 bar)
  8. Manufacturing process demonstration coupon for storage systems
  9. Manufacturing process demonstration coupon for pipes to load/unload H2/NH3 in vessels
  10. Manufacturing process demonstration coupon for joints on hydrogen storage tank onboard
  11. Demonstration coupon with complex geometry with hydrogen diffusion barrier coating or surface treatments
  12. Demonstration coupon with large areas of hydrogen diffusion barrier coatings or surface treatments


Research in a representative environment: marine and compatibility with hydrogen and ammonia

The behaviour of the HYSHORE products will be researched at the HarshLab (BiMEP). The prototypes and coupons manufactured with the feasible minimum prototypes of manufacturing means will be validated at Tecnalia workshops and laboratories to demonstrate and validate the technology that has been developed.


Exploitation, Dissemination and Business Models

The project results shall be disseminated and the plan defined to exploit them.
