Gamesa launches innovative anti-icing paint for wind turbines

By WPED Contributor | April 16, 2014

GamesaGamesa has developed a system for the prevention of ice formation on wind turbine blades. This solution, called Bladeshield, consists of an anti-icing paint which not only prevents the formation of ice but also boosts the paint’s resistance to erosion.

The Bladeshield system is the result of the development of an innovative procedure for obtaining the mix, as the additive is dissolved first in the ideal dispersing agent and then in the paint base. This results in a homogenous mix that doubles the paint’s anti-erosion and durability properties.

The solution was processed under the scope of the Azimut project for the development of offshore technology. This project is being sponsored by the Centre for the Development of Industrial Technology. This system is the result of three years of research on the use of new raw materials in wind energy, specifically the application of nanomaterials in the development of coatings.

Bladeshield, the company’s first anti-icing solution, is targeted at satisfying the growing need for systems that optimize blade performance and availability at wind farms located in cold regions.

This new system is apt for use in Gamesa’s own 2.0 to 2.5 MW and 5.0 MW onshore and offshore platforms as well as in other manufacturers’ products.

“Although Gamesa already had blade de-icing systems, it has developed this innovative solution in anticipation of the emerging needs of our increasingly sophisticated and demanding customers,” said José Antonio Malumbres, Gamesa’s Chief Technology Officer. “Gamesa has attempted to remain one step ahead, using nanomaterials to create a system that not only prevents ice formation but also improves anti-erosion performance.”

In addition to this anti-icing solution, Gamesa recently unveiled two systems for detecting and eliminating ice on blades that have been custom-developed for Gamesa’s suite of 2.0 to 2.5 MW turbines. Gamesa’s portfolio of turbines includes products specifically configured and adapted for sites that undergo extreme weather conditions, including sub-zero temperatures. Against this backdrop, the company is also developing another ice prevention system in collaboration with Finnish technology provider VTT for its platform of 5.0 MW turbines.

Development of wind farms in cold climates is growing. EWEA forecasts that between 45 and 50 gigawatts of wind energy will be built in cold climates by 2017, 72% more than at year-end 2012. Gamesa has already established a presence in northern Europe, specifically in Finland, where it has signed two framework agreements with Tuuliwatti for the supply of 285 MW and 135 MW, and Sweden, where it has been contracted to supply four G114-2.0 MW turbines to Eolus Vind. Gamesa is also present in Canada and China.

    The proposed technology which Gamesa will use is a coating which is embedded with carbon nano-tubes and the current for heating the blade surface is generated through electromagnetic induction. This same type of technology has been prototyped and patented already in aerospace. Vestas also has a pending patent on nano-material enabled blade coatings, so hopefully Gamesa did their homework on IPR. We don’t want to see another Storm Control.
