World first: with Hoffmann Green, the VALOREM Group announces the pouring of a wind turbine foundation made exclusively of 0% carbon-reduced clinker concrete.
Hoffmann Green Cement and the VALOREM Group, a pioneering independent producer of green energy in France, have announced the pouring of the world’s first wind turbine foundation made from 0% carbon clinker concrete.
At the Plaine des Moulins wind farm in Jazeneuil (Vienne), the VALOREM Group wanted Hoffmann Green and its partners to carry out a world first: the pouring of a wind turbine foundation using 630 m3 of carbon-free concrete. The use of decarbonated concrete resulted in a saving of 33 tonnes of CO2, i.e. 32% less than with traditional concrete, without any change in the construction method.
This achievement is all the more remarkable in that it involves a very demanding application where the casting is carried out in a single operation with a very high density of reinforcement to ensure the durability of this type of structure.
The La Plaine des Moulins wind farm will comprise 5 wind turbines, each 180 metres high at the tip of its blade, with a total installed capacity of 18 MW. It will generate around 42 GWh of green electricity, equivalent to 18.6% of the electricity consumption of the Haut Poitou local authority. The wind farm is scheduled for commissioning in early 2025.
