Hoffmann Green Cement Technologies and VALOREM Group have poured what the companies call the world’s first wind turbine foundation made from 0% clinker decarbonized concrete.
Taking place at the Plaine des Moulins wind farm in Jazeneuil, France, the companies and its partners poured the foundation using 630 m3 of decarbonated concrete. The company says the use of this material resulted in a 32% less carbon dioxide use.
The wind farm is set to comprise five wind turbines, each 180 meters high at the blade tip, with a total installed capacity of 18 MW. Expected to generate 42 GWh, the wind farm is scheduled for commissioning next year.
“We are very proud to be part of this world premiere: the pouring of the first wind turbine foundation using clinker-free decarbonized concrete,” says Julien Blanchard and David Hoffmann, co-founders of Hoffmann Green Cement Technologies.
“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.”
In addition to testing, ongoing technical exchanges have been held with the project’s partners, including CTE Wind on dimensioning of the wind turbine foundation and the performance of suitability tests and a prototype with the RBS and Lepine TP teams.
