Hoffmann Green Cement and The VALOREM Group, an independent producer of green energy in France, 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.
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.
