A unique collaboration project

During autumn of 2020, Rabbalshede Kraft and Euromekanik initiated a collaboration project that will provide 100% green hydrogen with the help of wind power. The goal is to open new possibilities for knowledge exchange and technology development for sustainable production of green hydrogen. The project has received grants from the Swedish Environmental Protection Agency and the initiative “Klimatklivet” which support local climate impact investments.

Why do we want to do this?

We are constantly working to expand our offer within renewable energy, with the ambition to find new ways forward towards a sustainable transition. In the transition to a fossil-free society, we see green hydrogen as an enabler for the necessary link between the energy, industry, and transport sectors.

Our wind farm in Högen, in Lilla Edet Municipality, has optimal conditions for this pilot project, mainly because of the size of the farm and its proximity to both the industrial cluster in Stenungsund, as well as Gothenburg.

From idea to finished green hydrogen plant

The road to a completed green hydrogen plant is not straight forward. Since there are no similar green hydrogen projects in Sweden yet, there are no obvious permitting processes in place. As we are one of the first players in Sweden to invest in green hydrogen, we have been bounced between different authorities and received different directives depending on who we have talked to.

Now we know what we must do, and we plan to submit a permit application to the County Administrative Board in the early 2024. If everything goes well, we hope to start construction in 2025.

What do we mean by green hydrogen?

At Rabbalshede Kraft we have a unique opportunity to produce green hydrogen directly from our wind parks. To produce hydrogen, only two ingredients are required - electricity and water. The water molecule is split using an electrolyser, and we get hydrogen and the by-products oxygen and heat. Since we plan to connect the hydrogen plant directly to the wind farm's internal grid, we will only use electricity from our wind turbines to produce the hydrogen. In other words, we do not buy electricity from the grid - this way we know that our hydrogen is truly green.

The green hydrogen is compressed and filled in a mobile storage facility that we can transport to customers in the local region. Our hope is that the pilot project will also teach us how to utilise the oxygen and heat in the best possible way.

Since this is a pilot plant, we have limited the power of the electrolyser to only 1 MW, which results in a maximum of about 5 500 MWh/year. This corresponds to about 450 kg of green hydrogen per day, which is enough to refuel almost ten large trucks. However, hydrogen production will not run at full capacity all the time but will vary depending on whether the wind power electricity is sold directly to the grid or whether we choose to make green hydrogen from parts of it.
