Floating Offshore Wind Development in the Baltic Sea
SeaSapphire, powered by Eolus and Simply Blue Group, will utilise innovative and cutting-edge floating offshore wind technologies to produce zero-carbon electricity in 4 wind parks in Sweden and Finland. The development aims to be a stepping stone to help Sweden and Finland progress towards a net-zero future and handle the increasing demand for electricity.
SeaSapphire propose to develop four floating wind projects Herkules, Skidbladner in Sweden and Wellamo and an undisclosed project in Finland. The projects are in the consenting stage and in parallel, a strong focus is put on supply chain development to provide opportunities for local job creation and commercial scale alternatives use of energy opportunities in Sweden and Finland.
The projects are estimated to produce up to 40TWh/year which contributes to Sweden’s and Finland’s need to increase energy production capacity for the foreseeable future and at the same time maximise financial benefits and generate long term jobs for its local communities.
Floating Offshore Wind
Floating wind foundations are normally used in deep waters where fixed foundations are no longer economically feasible. WindEurope estimates 80% of the wind resource in Europe is in waters beyond 60 m deep. Therefore, floating wind is going to play a key role in the development of offshore wind pipelines in many countries including Sweden and Finland.
An additional benefit with floating wind is that the wind parks can be located further off the coastline where wind conditions in most cases are better, the disturbance on shipping and fishing is less, the environmental impact is lower and the visibility from the coastline is less.
The 4 projects aim at bringing commercial and industrial large scale benefits to Sweden and Finland by establishing industry grade industrial development for the supply of the technologies and benefit from the anticipated growth of the market for floating offshore wind.

Alternative use of Marine Space
Seaweed farming can provide a sustainable healthy food source easily incorporated into most foods and can also be used for bio-fuels production. Seaweed is fast growing, fix carbon, phosphorus and nitrates, produce oxygen and has a carbon negative footprint.
An offshore wind park can host seaweed farms and contribute to the build up of an industry for both nutrients and biomass that has a negative carbon footprint
SeaSapphire aim at exploring the potential of using the marine space in the parks for seaweed farming and will work with local companies, universities and researchers to evaluate the potential in the Baltic Sea.
Alternative use of Produced Energy
SeaSapphire has the ambition to explore the establishment of e-Fuels production close to the wind parks in collaboration with local stakeholders. e-Fuels e.g. hydrogen, green ammonia, HVO, Sustainable Aviation Fuel, e-methanol; can be produced with the electricity generated from wind parks, water and CO2 from the air. In contrast to conventional fuels, they do not release additional CO2 and are climate neutral in the entire balance.
Thanks to their compatibility with today’s internal combustion engines, e-Fuels can be used as “drop-in” fuels in hard to abate sectors like aviation, marine transport and chemical production and will enable re-use of existing oil and gas infrastructure to be transitioned from fossil based to sustainable fuel production and storage. This enables us to manage limitations in curtailment, electrical grid infrastructure constraints and variability of renewable energy which may affect electrical grid robustness and stability.
The projects will contribute with up to 40TWh/year to Sweden’s and Finland’s energy production targets of an estimated 240TWh additional energy production capacity needed by 2045.
We will explore alternative and sustainable ways to use the produced energy and the marine space used by the parks. We will seek collaboration with local research organisations, innovation initiatives, universities and industries to explore the potential for e-Fuels, Carbon Dioxide Removal (CDR) and Seaweed farming.
We are dedicated to developing sustainable and transformative projects, working with the seas, and enabling communities to benefit from the projects. Therefore, we commit to having a continuous and strong stakeholder and community engagement to develop sustainable jobs and supply chains related to floating offshore wind as well as exploring alternative use of energy production capacity and use of marine space.
About the Partnership
SeaSapphire brings together a strong partnership to help unlock Sweden’s and Finland’s floating offshore wind potential. The partnership is comprised of Eolus, a leader of wind power development in the Nordics since 30 years and Simply Blue Group, a leading Irish “Glocal” blue economy developer in floating offshore wind, wave energy, e-Fuels and sustainable aquaculture for the past 10 years.
Eolus is one of the leading developers of renewable energy in the Nordics and are active in the whole value chain from development of green field projects to construction and operation of renewable projects. Eolus offers attractive and competitive investments in the Nordic and Baltic countries, Poland and the United States. The total project portfolio adds up to over 17 GW.
Simply Blue Group
Headquartered in Cork (Ireland), and with offices around the world, is a leading early stage developer of sustainable and transformative marine projects that work with the oceans and enable communities to benefit from blue growth. Simply Blue Group’s projects cover floating wind energy, wave energy, e-Fuels and CCS and sustainable aquaculture. The mission is to raise awareness of the oceans’ potential, pioneer marine project development and collaborate with partners to build a sustainable blue economy and communities. Simply Blue Group has a portfolio of floating wind power projects of more than 10GW.
