Wind to hydrogen. 1 MW
Högen is the name of a small wind farm outside Lilla Edet, along the river Göta älv between Gothenburg and Trollhättan. It is not far from the large chemical industry cluster around Stenungsund, where a lot of hydrogen manufactured directly or indirectly from fossil sources is used today. At Högen, wind power will be converted directly into renewable hydrogen.

Högen is a wind farm with three turbines in Lilla Edet municipality. Next to the wind turbines, a one-megawatt hydrogen plant is under development. As a pioneer in combining wind farms with on-site hydrogen production, the plant navigated a complex permitting process before breaking ground. It is set to begin delivering hydrogen in 2028. The electrolysers will be connected directly to the internal grid of the wind farm, so that most of the hydrogen can be produced from on-site wind power, with renewable electricity from the grid as a back-up when there is no wind. The hydrogen will be compressed and filled into mobile storage units and tube trailers, then trucked to nearby industries and refuelling stations along the west coast, helping to reduce emissions from both chemical production and heavy road transport. By operating both the wind farm and the hydrogen plant at the same site, the project can test flexible, cost-efficient production that follows the wind and shows how small-scale, local hydrogen hubs can work in practice. Högen is developed by Rabbalshede Kraft, an energy company that operates several energy parks, mainly in southern Sweden. They combine wind and solar power with battery storage and now green hydrogen. They are also involved in the plans in Skövde.
