STOCKHOLM, Sweden  OX2 is progressing preparations for the planned energy hub Neptunus in the southern Baltic Sea offshore Sweden.

This will have an installed capacity of 1.9 GW and will produce both electricity and hydrogen. It will be located in the Swedish economic zone, 50 km from the coast of Blekinge, and will comprise offshore wind turbines and installations to convert electricity to hydrogen.

Its estimated annual electricity production of 8 TWh would correspond to about 5% of Sweden’s current annual electricity consumption.

Over the past two years, OX2 has screened and conducted surveys in the area. Its next priority is to compile an environmental impact assessment for submission during 2023-2024.

The company aims to have the energy hub in operation in the early 2030s. It will also investigate if the oxygena byproduct of hydrogen productioncan be used to oxygenate the bottom waters of the Baltic Sea in the project area.

OX2 projects offshore Sweden

In June 2022, OX2 submitted a permit application under the act of Sweden's Exclusive Economic Zone to construct an offshore wind farm in the Swedish Economic Zone between the islands of Gotland and Öland.

In September 2022, OX2, together with Ålandsbanken Fondbolag, announced it was developing offshore wind power in two projects, one to the south and one to the north of Åland. The government of Åland issued a permission to carry out investigations for the projects. Therefore, OX2 is including its share of the projects, estimated at about 5,000 MW, in its project development portfolio.

In December 2022, OX2 agreed with Gasgrid Finland and Nordion Energi, gas transmission system operators in Finland and Sweden, and Copenhagen Infrastructure Partners (CIP) to explore the possibility to develop a new offshore hydrogen pipeline infrastructure to enable transportation of clean, sustainable hydrogen connecting Finland, Åland, Sweden, Denmark and Germany. The project, the Baltic Sea Hydrogen Collector, will be a large-scale, cross-border collection and transportation infrastructure for green hydrogen. The project is initiated by the Finnish and Swedish gas transmission system operators Gasgrid Finland Oy and Nordion Energi AB together with OX2 and CIP.   

More recently, OX2 signed an asset management agreement last month for a wind farm owned by Greencoat Renewables Plc in Sweden. The agreement is a long-term, full-service asset management agreement for the operational wind farm Ersträsk South and will also include support for the future takeover of another asset. OX2 will provide technical, commercial and financial management of the wind farm, Ersträsk South, to ensure optimal asset performance on behalf of Greencoat. The wind farm consists of 36 Enercon turbines (101 MW in total) and has been operational since 2021.
