The Green Nacelle: pioneering natural-fibre composites in wind energy
comments Deimann. " Due to higher raw
material costs and the manufacturing process
being technically more advanced, the cost of
production using NFC is roughly 20-30%
higher than GRP. However, there is a recycling
advantage using sustainable composites,
and this advantage is likely to significantly increase
in the future. We must think in five-year
steps. We are sure that there will be at least a
small-series production of NFC nacelles by
the end of the decade. From 2030 onwards,
NFCs could have a relevant market share in
the nacelle market, and we will hopefully also
witness the first NFC blade projects. "

formance over time, using their findings to
develop a detailed long-term case study for
large outdoor NFC structures.
End-of-life options for
composites in the wind sector
With massive CO2
equivalent
savings,
renewable raw materials, and significant
reductions in energy consumption during
manufacturing, natural-fibre composites
make a compelling argument for change
even before a product reaches end of life.
With more than 2.5 million tons of composite
materials in use in the wind sector
globally, and the first generation of turbines
now starting to come to the end of
their operational lives, considerable focus
is now aimed at addressing these issues.
Greenboats themselves have included several
key end-of-life assumptions that are
specific to natural-fibre composites in their
life cycle analysis, as well as reaffirming the
benefits of their panel-based approach.
" We believe strongly that a panel-based
approach to component design and manufacture
has massive benefits. Our vision includes
the repurposing or upcycling of panel sections
from retired NFC wind energy components,
massively extending the useful lifespan of
the materials, " commented Friedrich
Deimann, Greenboats.
Finally, only at the absolute end of their
life, NFC components can be shredded
and separated in several steps. The shredded
material can now be used in a pyrolysis
process to produce synthetic gas, which is
used to make methanol or replace conventional
refinery products such as heavy oil
in industrial furnaces (Source: Schmehl
et al. 2008). But this is just an example of
what is possible, and not a defined future.
In addition, there exists the possibility for
highly-efficient energy recovery within the
standard waste management system.
Sowing the seeds for the increased
adoption of NFCs in wind energy
The importance and relevance of the
Green Nacelle project has certainly been
noted by leading industrial players and the
composites industry itself. Earlier in 2021,
Greenboats, Sicomin and Bcomp were
nominated as JEC Innovation Awards
finalists, and since the nacelle was delivered,
Greenboats has received enquiries
from a significant number of wind energy
manufacturers.
Within the wind energy industry, a nacelle
was the ideal first application for NFC
materials because the structural loads were
easier to manage, compared to a blade for
example. And while the primary goal of
the Green Nacelle project was to confirm
the possibility of building a nacelle out of
significantly more sustainable materials,
Greenboats has stated that they now see
significant promise for future adoption of
NFCs in even larger components.
" We are convinced that we can engineer
and build any size nacelle, even those for
the industry's largest turbines, using our
panel-based process and NFC solutions, "
Challenging raw material
suppliers to do better
The manufacturing stage of the Green
Nacelle progressed rapidly and without
issue, the Sicomin epoxy products and
Bcomp's ampliTex™ natural-fibre technical
products performed as expected and also
met all structural requirements defined
by the client and composite engineering
team. When asked what more could be
achieved in material technology, Deimann
added, " Already the product we made is approximately
80% based on natural materials.
The sustainability can be further improved by
increasing the bio-content of the resin system,
and this is something we would be more than
happy to evaluate. "
Sicomin are indeed up for the challenge as
Philippe Marcovich, President, Sicomin,
comments: " We work continuously on R&D
developments to enhance our innovative
chemistries. Today, we have the highest
bio-content on the market and can supply
the industrial volumes that the wind energy
market would need. Moving forward, we are
constantly looking at new formulations and
developments that will let us provide our
customers with even higher levels of sustainability
in the future. "
Greenboats, Sicomin and Bcomp look
forward to further feedback from the DOT
test programme as the project moves into
the next phase.
