The best projects are usually silly ideas to start with. And that is also necessary: If you want to have a disproportional impact with your work you need to be both: non-consensus AND right.
If you are consensus and right: it is just „another one of those“. If you are wrong. Well, you are just wrong.
Same counts for the Green Nacelle. We were facing a lot of skepticism when we first announced the project. „[…]there is a reason why these materials have never been used in the wind power industry“…
The happier we are to see that the first Windpower industry insiders are picking up on the development. In his Podcast #Uptime, Allen Hall shows that he has an intuitive understanding of the potential of the technology and why we have chosen a Nacelle to expose the wind power industry to sustainable composites. Allen is right: It will boil down to the cost of production but there is a recycling advantage using sustainable composites, and this advantage is most likely to significantly increase in the future.
With this project, we want to provide proof and create the confidence needed for businesses in the wind power industry to adopt more sustainable materials.
The topic is more relevant than ever: Today, 2.5 million tons (!) of composite materials are in use in the wind sector globally, and the first generation of wind turbines is now starting to come to an end.
To make sure the project will be a success we teamed up with the best: We are using Bcomp´s Amplitex reinforcement fibers as well as the Sicomin´s Greenpoxy resin. As the core material, we are using Balsa Wood.
Robin Zinkmann of Bremerhaven-based Design and Engineering Company judel/vrolijk & co helped us to ensure compliance with the requirements of our client. For example, the Nacelle has to withstand high wind loads of 200 km/h and the guard rails on the top have to hold 2.000 Kg.
This picture shows the Nacelle leaving our Bremen Workshop back in January. Currently, additional equipment is being installed at our client’s workshop in the Netherlands. Once the assembly is complete it will move to its testing facility in the harbor of Rotterdam.
You can expect the first images of the Green Nacelle in action by April!
Moreover, we will publish the results of the Life Cycle Assessment (LCA) that show how much CO2 can be reduced and energy can be saved over the lifetime of the product, using Sustainable Composite technologies.
We will also dive deeper into the economies of scale manufacturing large composite structures such as nacelles. As Allen Hall pointed out in his podcast „Uptime“: It will boil down to the cost of production but there is a recycling advantage using sustainable composites, and this advantage is most likely to significantly increase in the future-
