A test application was conducted in which super hydrophobic coating HIREC was painted on key areas of the blades to confirm whether it would be effective in improving power generation efficiency.

Points of problems and challenges

In wind power generation, a decrease in power generation efficiency due to snow and ice accretion in winter can be a problem. There is also a method of melting snow and ice by heating the blades, but there are issues with high heating power costs and run-back icing where the water that has melted snow and ice freezes again on the blades.

Countermeasure points

A test application was conducted in which super hydrophobic coating HIREC was painted on key areas of the blades to confirm whether it would be effective in improving power generation efficiency.


It was found that the power generation efficiency was improved by about 9 points compared to the case where HIREC was not painted.


Implementation overview
place Wind power generators in the high mountains of Europe (regions where the temperature drops below -10°C in winter and snow accumulates)
Implementation content Compare the power generation efficiency for one year between a normal wind power generator without HIREC and a wind power generator with HIREC applied to the key points of the blades.
result Power generation loss rate of wind turbines without HIREC coating (average for all units): about 27.5%
Power generation loss rate of wind turbines coated with HIREC: about 18.5%↓
