Subsea Grids Supporting Marine Biodiversity: Improving Undersea Resiliency with Nature Materials

Biorock, sea-concrete, sustainable concrete – a fascinating concept with many different names and applications. For the third edition of RGI and OCEaN’s Nature Inclusive Design (NID) webinar series, we explored these natural, environmentally-sourced construction materials as a new solution in the context of offshore electricity grid infrastructure.

The highlight of this online discussion was presentations from Red Eléctrica, the Spanish transmission system operator,  and ECOncrete on their innovative collaboration on ecological cable protection in the subsea trench between the islands of Lanzarote and Fuerteventura in Spain.

Our NID webinar series focuses on solutions applied in offshore wind energy and related grids for nature-positive outcomes. In our third edition in this series, we looked into solutions which utilise ‘biorock’ and discuss the following:

• Natural, eco-friendly construction materials for undersea use;
• Scour and corrosion protection for offshore structures made from natural sources;
• Environmentally-sourced materials used to repair and reinforce offshore infrastructure.

Thank you to all participants who joined the webinar to learn more about the biodiversity-enhancing aspects of these construction materials and their installation in Spain, including how marine life is now flourishing around the cable!
