Engineering firm Greenboats and bio-epoxy resin company Sicomin have produced a nacelle made from natural fibres that they aim to test in the harbour of Rotterdam this spring.

They claim the structure is one of the world's largest natural fibre composite (NFC) structures and marks the first use of such materials for an offshore wind turbine nacelle. Steel, aluminium, and polyester-based and epoxy-based glass-fibre reinforced composites have been used to date.
