In La Ciotat, Holcim said it has acquired a minority equity position in BW Ideol as it looks to scale the construction of offshore wind infrastructure using floating foundation technology.

The companies are establishing a strategic partnership to supply innovative materials for a pair of fabrication lines for concrete floating foundations being developed by BW Ideol in southern France and northeast Scotland. Holcim said its patented lightweight structural low-carbon concrete is suited to offshore wind applications, and described the arrangement as a local-for-local approach intended to benefit local economies.

BW Ideol said it has 15 years of experience in the design, engineering and fabrication of offshore floating wind foundations. The company also has equity ownerships in two floating wind projects: one off Scotland’s Northeast coast with a capacity of 960 MW, and one off France’s Southern coast with a capacity of 270 MW.

Holcim said the investment aligns with its NextGen Growth 2030 strategy, which positions sustainability as a driver of profitable growth. The company noted it has previously supplied onshore wind foundations in Australia, Croatia, Denmark, Poland, Spain and the UK, as well as offshore wind foundations off France’s northern coastline.
