They aim to include 3.1GW of offshore wind capacity and electrolysers capable of producing up to 370,000 tonnes of hydrogen per year at the energy hub 50km off the coast of Blekinge.
If both permits are granted, OX2 believes it can start construction in 2030.
The project is in Sweden’s exclusive economic zone and Neptunus submitted a Natura 2000 permit application to the county board of Kalmar in October last year.
Neptunus will have up to 207 wind turbines with a maximum height of 420m, for a total installed capacity of 3.1GW. The electricity production is projected to be about 13-15TWh annually – the current total electricity consumption of the Blekinge and Skåne region.
Along with the wind farm and offshore hydrogen production permits, OX2 and Ingka Investments have sought a permit for a pilot project to oxygenate the Baltic Sea. Oxygen is a byproduct of hydrogen production by electrolysis. The development partners claim that using this byproduct to oxygenate the Baltic Sea will help to restore marine life in an area with oxygen deficiency.
OX2 described the Neptunus energy hub as “one of the first of the next generation of wind farms”. It stated: “By producing renewable energy and hydrogen, Sweden will be able to secure energy for sectors that can’t be electrified.”
The project is in an early development phase and 1.9GW is included in OX2’s project development portfolio.
OX2 and Ingka Investments have partnered to develop six offshore wind farms in Sweden with a combined capacity of more than 13GW.
