Subsea 7 to Explore Pairing Floating Offshore Hydrogen with Floating Wind Farm Off Scotland

Subsea 7, in collaboration with OneSea Energy, has secured GBP 150,000 (around USD 187,000) in funding from the Scottish government to investigate pairing a large-scale floating hydrogen production system with a floating wind farm offshore Scotland.


The funding was awarded as part of the Hydrogen Innovation Scheme under which a total of 32 projects have been awarded a share of GBP 7 million.

Following a memorandum of understanding (MoU) signed in 2022 and with this funding in place, Subsea 7 and OneSea Energy will now look into the technical feasibility and commercial value of coupling a large-scale floating hydrogen production unit with a floating offshore wind farm.

Through the feasibility study, the two companies intend to explore the opportunity and prove the relevance of floating hydrogen production in the Scottish context, based on OneSea’s developed technology and concept, and relying on Subsea 7’s experience in broader energy systems integration and delivery of projects in Scotland as well as understanding of the Scottish business environment, supply chain and market context.

As explained, Subsea 7 will undertake engineering studies related to the integration of OneSea Energy’s floating hydrogen production unit within the floating wind farm, including the electrical architecture system and the hydrogen export system. Both companies will perform an economic analysis to establish a commercial model and determine the potential value for Scotwind floating wind developments.

Stian Sande, Strategy Director Energy Transition at Subsea 7, said: “We are delighted to be moving forward together with OneSea Energy in exploring and developing solutions for large-scale offshore hydrogen production in general and, for this study, specifically in a Scottish context. As a global leader in delivering complex energy projects, we continue to work with our partners and clients to make the energy transition possible.”

Diego Mejia Velez, Managing Director of OneSea Energy, added: “We are thrilled by the recognition of the Scottish Emerging Energy Technologies Fund – Hydrogen Innovation Scheme to support our development of large-scale offshore production of hydrogen in Scotland. We look forward to deepening the collaboration with our partner Subsea7 and contributing to the deployment of offshore hydrogen production solutions that will be vital to the development of the hydrogen economy and acceleration of the energy transition.”
