- RWE and TORC prove oyster reef restoration is feasible within offshore wind farms
- Six-month study delivers blueprint for guiding the deployment of biodiversity gains
- Project improves RWE’s preparedness for implementing net-positive marine impacts.
RWE, one of the world’s leading offshore wind companies, and The Oyster Restoration Company (TORC) have successfully completed a feasibility project that proves large-scale native oyster reef restoration can be executed at offshore wind farms in the North Sea.
This is an important achievement for RWE and a pathfinder for the wider offshore wind industry, to identify credible biodiversity solutions that are scalable and verifiable, in line with efforts to positively impact on the marine environments around its offshore projects.
Throughout the feasibility testing, RWE and The Oyster Restoration Company jointly developed a series of technical assessment, evaluations and solutions from engineering and deployment to verification frameworks.
Flat oysters are an important species because they can create reefs that provide food and breeding grounds for many other species. Due to the harmful impacts of factors such as overfishing, pollution, and parasites, only 5% of the pre-industrial population remains across the North Sea. The project is a research initiative, which is supported by RWE and carried out at TORC’s hatchery in Scotland. Through laboratory tests, the project evaluated different natural and artificial hard substrates, such as shells or bricks, and to decide which could be deployed to maximize the creation of new reefs.
'The question is no longer if we can restore oysters at scale offshore' said Dr Nik Sachlikidis, CEO of The Oyster Restoration Company. 'Together with RWE, we’ve combined hatchery capacity, engineering know-how, and science to deliver a pathway for measurable biodiversity gain. Practically, affordably, and now.'
Dr Thomas Michel, RWE COO Offshore Wind, added: 'By acting early, RWE is stepping up its capability and readiness to help benefit marine biodiversity in and around its offshore wind projects. We have a firm responsibility to not just mitigate but also to enhance the environments in which we build and operate. Through this promising initiative with The Oyster Restoration Company, we have established a verifiable tool that demonstrates tangible results, and supports the credibility of RWE’s net positive ambitions on biodiversity.'
The learnings from this project are expected to support the ambitions of offshore wind companies to contribute to the restoration of important marine habitats across wide areas of the North Sea in the UK and Europe. These efforts are key to driving progress among offshore wind companies, to achieving a net-positive impact on biodiversity.
