Ørsted to Rewild Offshore Wind Farms

Ørsted and ARK Nature have partnered to test the potential of rewilding principles to restore ocean biodiversity and develop the best ways to scale up work globally to ensure an overall net-positive impact on nature when building offshore wind farms.

One initial focus is restoring shellfish reefs that are fundamental to ecological restoration in the North Sea, Ørsted said.

Ørsted aims to deliver renewable energy that has a net-positive biodiversity impact for all new energy projects commissioned by 2030.

ARK Nature is one of the founding partners of Rewilding Europe and a pioneer of the rewilding approach to nature restoration, which has already proven effective on land. Together, ARK and Ørsted are combining this expertise to realise a shared ambition to support and nurture healthy oceans that can sustain diverse ecosystems and a healthy society.

”When it comes to tackling the climate crisis and biodiversity loss, there’s a real need for speed. We need urgent action – but that speed must not come at the expense of nature, and Ørsted believes it doesn’t have to,” Rasmus Errboe, Head of Region Continental Europe at Ørsted, said.

”With this new collaboration, I’m excited to add to our existing, ambitious global biodiversity programme. Together with ARK, Ørsted will implement innovative new restoration projects and study how rewilding can contribute to improving the health of our oceans, and how the offshore wind sector can enhance that contribution.”

The partnership will start in the North Sea, where Ørsted and ARK are setting up a Marine FieldLab for rewilding. Our first step is finding the most suitable location on ecological grounds, and from there we’ll develop and implement promising rewilding measures. Importantly, the impacts will be closely studied, and what we learn will be used as we refine and develop ways to scale up positive biodiversity impact globally.

Jos Rademakers, CEO of ARK Nature, said: ”ARK Nature and Ørsted are ultimately pursuing the same goal: self-sustaining, healthy oceans. We’ll aim to restore the vital natural processes and contribute to creating wind farms that have an overall positive impact on nature and humanity. And we know we have to deliver that impact as soon as we possibly can.”

Currently, there are very few places remaining in the North Sea where shellfish larvae can attach and create new reefs, Ørsted said. The partnership will test and develop the best ways for wind farms to provide this and support biodiversity. Once the approach has been sufficiently tested, it could potentially be applied at a larger scale around the world.

Rewilding involves taking an ecosystem-wide view and creating conditions in which nature can recover and thrive in the long-term.

The approach has never before been trialled at scale in the marine environment where the challenge is particularly acute, Ørsted said. The decline in marine biodiversity, driven in large part by global warming, is weakening the ocean’s role as a key global climate regulator. At the same time, the unprecedented expansion in offshore wind infrastructure – which is needed to halt global heating – means more interaction with the natural world we ultimately seek to protect.
