Hoffmann Green Cement Technologies (Paris:ALHGR):
The VALOREM Group, a pioneering independent producer of green
energy in France, and Hoffmann Green Cement Technologies, an
industrial player committed to decarbonizing the construction
sector by designing and marketing innovative clinker-free cements,
announce the pouring of the world's first wind turbine foundation
made from 0% clinker decarbonized concrete.
On the site of the Plaine des Moulins wind farm in Jazeneuil
(Vienne), the VALOREM Group wanted Hoffmann Green and its partners
to achieve a world first: the pouring of a wind turbine foundation
using 630 m3 of decarbonated concrete. The use of decarbonated
concrete resulted in a saving of 33 tonnes of CO2, i.e. 32% less
than with traditional concrete, and this without any change in
construction methods.
This achievement is all the more remarkable in that it concerns
a very demanding application, where pouring is carried out in a
single operation, with a very high density of reinforcement to
ensure the durability of this type of structure.
The Plaine des Moulins wind farm will comprise 5 wind turbines,
each 180 metres high at the blade tip, with a total installed
capacity of 18 MW, and will generate around 42 GWh of green
electricity, equivalent to 18.6% of the electricity consumption of
the Haut Poitou community. The wind farm is scheduled for
commissioning in early 2025.
Baptiste WALYN, Director of VALREA, VALOREM Group's
construction subsidiary, underlines: « The VALOREM Group is
delighted with this world first. Wind turbine foundations are often
the target of misinformation. While steel-reinforced concrete is
non-polluting for the soil, and while all wind turbine foundations
are removed at the end of the park's life and the concrete
recycled, we are also proving today that innovation can
significantly reduce their carbon impact on the park's overall
carbon footprint. The VALOREM Group is a company with a mission,
resolutely committed to reducing all its impacts ».
Julien Blanchard and David Hoffmann, co-founders of Hoffmann
Green Cement Technologies, said: “We are very proud to be part
of this world premiere: the pouring of the first wind turbine
foundation using clinker-free decarbonized concrete. This
achievement represents a key milestone for Hoffmann Green and
strengthens our position on the wind energy market within the
strategic renewable energy sector. This achievement is in line with
our partnership signed with Biobuild in October 2022. It will
enable us to promote eco-responsible construction methods while
guaranteeing the quality of the foundations, as part of our common
commitment to the ecological transition.”
Under the Energy and Climate Act, France aims to achieve a 33%
share of renewable energy in gross final energy consumption by
2030. The renewable energy market therefore represents a key growth
potential in which Hoffmann Green intends to strengthen its
position. In the wind energy market segment, almost 300 projects
are expected to be deployed in the medium term.
Many committed players.
Prior to this historic premiere, 5 years of testing were
required to assess the performance, durability and safety of H-UKR
cement and concrete. The Appréciations Techniques d'Expérimentation
(ATEx) issued by the Centre Scientifique et Technique du Bâtiment
(CSTB) are the result of this in-depth work, and cover complex
technical issues such as dimensioning under heavy load, which is
essential for wind turbine foundations.
In addition to the test phase, ongoing technical exchanges have
been held with the various partners, from the dimensioning of the
wind turbine foundation by CTE Wind to the calibration of the
concrete formulation, and the performance of suitability tests and
a prototype with the RBS and Lepine TP teams.
Mélaine Besse, Président of BioBuild, also said:
«Reducing the carbon footprint of renewable energy projects is
essential both for the image of our industries and for the
ecological transition overall. As the company responsible for
strategic studies and analyses, it was natural for BioBuild to join
forces with Hoffmann, with whom we share a common vision in favour
of eco-sustainable construction ».
Emmanuel Hamon, Senior site supervisor and Mickaël Leray,
Branch Manager at Lépine TP - Groupe Angevin, commented: «The
Groupe Angevin is involved in hydraulic civil engineering (waste
water, drinking water) and civil engineering structures (PS, PI,
small viaducts, wind farms, etc.). We immediately agreed to take
part in this sustainable project in order to bring our expertise in
the specific techniques required for this kind of project ».
Frédéric Limouzin, Concrete Sector Manager at RBS - CMGO,
stated: «The core business of Carrières et Matériaux du Grand Ouest
(CMGO) is the operation of quarries and concrete plants, as well as
the production, recovery, recycling and sale of sand and gravel. As
the first link in the construction chain, we are delighted to have
been associated with this iconic project in the Grand Ouest region,
which promotes environment-friendly construction ».
Eric LEBRE, Sales Director of CHRYSO/GCP added: «The
CHRYSO®Enviromix ULC 5500 technology developed specifically for the
H-UKR binder enabled RBS - CMGO to ensure quality and consistency
of manufacture throughout the duration of the Jazeneuil wind
turbine foundation project. Like Hoffmann, we are convinced that
innovation has a major role to play in creating the materials of
tomorrow ».
Thanh Binh Tran, Technical Director of CTE Wind
concluded: «As an engineering and consultancy company specialised
in the design of foundations for wind turbines, CTE Wind has
designed almost 30,000 foundations for 2,500 wind farms since it
was founded. This first project using 0% clinker concrete, which
reduces CO2 emissions, represents a strategic turning point in the
fast-growing renewable energy market ».
