OX2 has initiated the development of the offshore energy hub Neptunus in the southern Baltic Sea. The energy hub is estimated to have a total installed capacity of 1.9 GW and will produce both electricity and hydrogen.

The energy hub will be located in the Swedish economic zone, about 50 km of the coast of Blekinge. It will comprise of offshore wind turbines as well as installations to convert electricity to hydrogen. The annual production is estimated to 8 TWh of electricity, corresponding to roughly 5% of Sweden’s current annual electricity consumption.
OX2 has screened and conducted surveys in the area during the last two years and during the winter conducted consultations where authorities and the public have been informed and have been given the opportunity to submit comments. The next step is to compile an Environmental Impact Assessment (EIA) which will be submitted during 2023 - 2024. The energy hub is aimed to be in operation in the early 2030s.
Emelie Zakrisson, Head of Offshore Wind Development Sweden, OX2 commented: "The shift towards hydrogen, fossil-free industries and general electrification demands huge amounts of renewable energy and Neptunus is strategically located to play a key role in this transition. I am happy to announce we have included another project to the Swedish development portfolio."

OX2 will also investigate if the oxygen, which is a biproduct of hydrogen production, can be used to oxygenate the bottom waters of the Baltic Sea in the project area. According to scientists in Sweden, Oxygenation can give ecosystems the boost they need to come to life and helps nature with eutrophication, the bloom of phytoplankton in water.
