What Eolink does

Eolink is a French developer and manufacturer of floating offshore wind turbines, founded in 2015 by Marc Guyot and headquartered in Brest, Brittany. The company is commercializing a patented pyramidal floating structure that distributes mechanical loads across four steel columns rather than a single tower, reducing steel mass by 30–45% versus conventional single-tower floating designs and enabling accommodation of larger turbines (>12MW) without mast vibration issues. Eolink serves the emerging deep-water floating wind segment, targeting offshore wind developers, energy utilities, and infrastructure providers in markets where bottom-fixed foundations are not viable.

Eolink's core product is the France-Atlantique 5MW pre-commercial floating wind turbine, currently in the manufacturing and assembly phase at the Port of Brest ahead of deployment at the SEM-REV test site off Le Croisic. The company has validated the technology through a 1:50 scale proof-of-concept (2016), a 1:10 scale prototype (2018 — France's first grid-connected floating wind turbine), and a 5MW demonstrator design certified by Bureau Veritas in 2022. Eolink is also developing the HT-20MW system, a 20MW class floating turbine project focused on a 66 kV high-voltage rotating connection, funded through the CORIMER 2022 award.

Eolink operates an enterprise field-sales go-to-market via strategic partnerships with major energy players, most notably ACCIONA Energía (24% principal shareholder acquired in 2022), Valorem (assembly and O&M partner), and Chantiers de l'Atlantique (steel fabrication). Revenue is expected to derive from a hybrid of floating wind turbine hardware sales, technology licensing of patented designs and modular shipbuilding-based manufacturing processes, and project development services. Commercial-scale deployment is targeted post-2030 with an LCOE objective of €35/MWh, supported by non-dilutive funding of €14.9M (France 2030) and €6.2M (CORIMER), and aligned with French government offshore wind capacity targets of 18 GW by 2035 and 45 GW by 2050.

Core offering

Eolink develops an integrated turbine-float system for floating offshore wind energy based on a patented pyramidal four-column structure. The company designs, manufactures and assembles floating wind turbines (5MW pre-commercial demonstrator France-Atlantique; 20MW HT-20MW in development) and licenses its pyramidal technology to offshore wind developers and energy majors. Manufacturing uses modular shipbuilding techniques with prefabricated stiffened-steel panels.

Product overview

Eolink develops an integrated turbine-float solution for floating offshore wind energy based on a patented pyramidal structure design. The product portfolio includes the France-Atlantique 5MW pre-commercial floating wind turbine (currently manufacturing phase), the HT-20MW 20MW system (under development), and a scaling methodology demonstrated through proof-of-concept (1:50), prototype (1:10), and pre-commercial (5MW) stages. The pyramidal design distributes forces across four columns, achieving 45% steel mass reduction compared to single-tower alternatives. Manufacturing uses modular shipbuilding techniques with prefabricated stiffened steel panels. The company operates from Brest, France, with a UK office in Glasgow.
