Sweden – OX2 has started work on the offshore energy hub Neptunus in the southern Baltic Sea. The energy centre will generate both electricity and hydrogen and is expected to have a total installed capacity of 1.9 GW.

The energy hub will be built in the Swedish economic zone, roughly 50 kilometres from Blekinge’s coast. It will include offshore wind turbines as well as facilities for converting electricity to hydrogen. The annual production is anticipated to be 8 TWh, or around 5% of Sweden’s current annual electricity consumption.

Neptunus’ anticipated electricity output would enable the creation of up to 225,000 tonnes of hydrogen per year.

Environmental Impact Assessment

Throughout the last two years, OX2 has screened and done surveys in the area, and during the winter, it has held discussions in which authorities and the general public have been informed and given the opportunity to provide opinions. The following phase will be to prepare an Environmental Impact Assessment (EIA), which will be submitted between 2023 and 2024. The energy hub is expected to be operational in the early 2030s.

OX2 will also look into whether the oxygen produced as a byproduct of hydrogen production may be used to oxygenate the Baltic Sea bottom waters in the project region.
