SEAHIVEX: modular concrete reefs for coastal resilence and ecological regeneration by FSC-TECH EU Srl

The SEAHIVEX project proposes the use of an innovative, ultra-durable concrete developed to create modular reefs and marine infrastructure that enhance coastal resilience while supporting the expansion of renewable energy at sea. This patented concrete, reinforced with glass fiber instead of steel, is highly resistant to corrosion and can remain structurally sound in marine environments for thousands of years, making it suitable for artificial reefs, floating platforms for wave-energy converters, offshore wind towers, and floating photovoltaic systems. The technology is already at a mid-to-high development stage (TRL 6–7), allowing real-world testing as soon as an appropriate offshore area is identified. Compared with traditional steel-based structures, FSC-TECH’s solutions are more cost-effective, easier to mass-produce, and significantly lower in environmental impact. By enabling stable wave-energy production, improving offshore wind infrastructure, and supporting next-generation energy storage systems (such as compressed-air storage and concrete hydrogen tanks) the project can contribute to decarbonizing coastal regions and diversifying renewable energy sources. Key challenges relate to the cost of demonstration activities and the need for suitable test sites, but FSC-TECH plans to co-invest and leverage national and EU funding opportunities. Collaboration with regional industrial partners, research centers and ENEA will support prototype development and integration into broader energy and industrial ecosystems.
