Aquaterra Energy and Seawind Ocean Technology have unveiled plans to co-develop what they say will be the world’s largest offshore floating wind and green hydrogen production project.
The HyMed project will be built in Italian ultra-deep waters and have a production capacity of 3.2GW of electricity. Of this, more than 1GW will be green hydrogen once production units are fully operational.
Currently in its first phase of permitting, with the grid connection and the environmental impact assessments under way, the project is expected to be completed in 2027.
Aquaterra Energy will provide its offshore engineering and green hydrogen production expertise to ensure the right approach and solutions are chosen to drive the development forward. This will be complimented by Seawind’s multiyear expertise on floating offshore wind technology.
The project partners expect to transport the green hydrogen onshore by pipeline or by vessels to global markets when complete.
The collaboration will provide a unique offering and act as a template for future offshore renewable energy projects between the companies including a 300MW exclusively hydrogen production project in southwest Greece named Icarus.
Renewables Director at Aquaterra Energy Anne Haase said: “With governments and business recognising the value of hydrogen as a vital resource for net zero initiatives, energy security, and guarding against volatile natural gas prices, we are hugely excited by the opportunities for production presented by this new partnership.
“Seawind’s fully integrated and scalable floating wind model offers a clear path to cost-effective industrial scale production – and we are delighted to be able to provide the final piece of the production puzzle for it.”
CEO at Seawind Ocean Technology Dimitrios Moudouris added: “We are pleased to partner with Aquaterra Energy in these highly impactful projects in Italy and Greece. We consider the Mediterranean to be the best area where significant offshore wind projects can be developed and cross-border synergies can be made, serving Europe and MENA.
“Aquaterra Energy has displayed its expertise and commitment to green hydrogen through existing projects and we identified an experienced partner to enable us to accelerate our ambitious offshore wind and hydrogen project development strategy.”
