The NEMMO project has installed a set of tidal turbine blade panels made from fibreglass and a gel-coat coating for testing at the HarshLab facility. The samples, taken from the current Magallanes’ turbine blade, will be submerged for six months to determine the level of biofouling on the surface. These results will then be used as a reference for the development of new blade materials and coatings.

The creation of novel coatings and materials is a core part of the NEMMO project. After extensive modelling and testing, the team will define the optimal material composition, textures and surfaces to reduce wear on the blade. The wider objective is to lower maintenance costs and increase the yield of tidal turbines, and to improve the cost-effectiveness of tidal energy overall.
