The innovative natural fiber composite (NFC) Green Nacelle for offshore wind turbines is one of the developments selected as a finalist for the JEC Innovation Awards 2021. The 3 project partners Sicomin, Châteauneuf les Martigues/France, in collaboration with Greenboats GmbH, Bremen/Germany, and Bcomp Ltd., Fribourg/Switzerland, have been nominated in the awards’ Renewable Energy category.
The Green Nacelle was designed by NFC innovators Greenboats, who were also responsible for the structural engineering, manufacturing and assembly of the nacelle. By incorporating Bcomp’s ampliTex flax reinforcements, FSC certified balsa wood cores and bio-based resins, the Green Nacelle’s NFC construction saves approximately 60% CO2 equivalent and reduces the energy consumption by over 50% compared to a nacelle made with existing GFRP technology.
Sicomin, the formulator and supplier of the range of GreenPoxy bio-based epoxy resin systems, supplied its DNV GL approved InfuGreen 810 resin system that was used to infuse the Green Nacelle’s main structural sandwich panels, as well as providing intumescent FR gelcoats, bio-based laminating resins and UV resistant clear coatings. Materials, as well as on-site technical support, were delivered by Sicomin’s German distributor Time Out Composites oHG, Bornheim-Sechtem.
In addition to the lower CO2 footprint, the natural fiber composite structure also introduces viable options for the end of the nacelles’ life unlike traditional GFRP structures.
The winners of the awards will be announced during JEC Connect which will be held on June 1-2, 2021.
