Coatings extend wind turbine life and slash costs

EU-funded research has developed new spraying systems for compressing millions of nano-particles to create a super-strong, long-lasting, water-resistant coating on the blades of wind turbines used for generating electricity. With it, wind farms can slash maintenance costs and blade life can be extended by up to 30%, the researchers say.

Offshore wind turbines face a battering from the elements. But newly-developed ‘hydrophobic’ coating techniques give ice and water droplets little chance of sticking to their blades, which boosts turbine performance and saves time and money for wind farm operators.

The work is being undertaken by the EU-funded Hydrobond project, coordinated by José María Guilemany from the Centre de Projecció Tèrmica (CPT) at the University of Barcelona. Together with a European consortium of companies and research centres, Hydrobond is developing new superhydrophobic coatings and improving how they are applied

The biggest wind turbine ever installed

"Alstom has installed the world's largest offshore wind turbine off the Belgian coast, the Haliade™ 150-6MW.
This is the largest offshore wind turbine ever installed in sea waters. Thanks to its 150-metre diameter rotor (with blades stretching 73.50 metre), the turbine is more efficient since its yield is 15% better than existing offshore turbines, enabling it to supply power to the equivalent of about 5,000 households".


Hydro-bond will participate within the forum Optimising Wind Farms In Cold Climates, being held across 26-27 November in Helsinki . Is the only event focusing on the commercial and technical complexities which impede on the operation of wind farms in cold and difficult climates.

The forum promises to bring the most effective and ground-breaking techniques for counteracting harsh weather conditions whilst preventing production loss.

Lowering maintenance costs in offshore wind turbines

The main drawback of offshore wind turbines has been the high running and maintaing costs, leading to lower profits for the industry. However, the offshore sector is adquiring a lot of experience of the marine environment from the present installations helping to push costs down.

The present explotation of the installed offshore wind turbines (around 7GW), including operation and maintenance (O&M), is an increasing business. At the moment, the O&M sector accounts for 500 million EUR a year. However, the pressure to keep the cost of energy from offshore wind farms low has led to new strategies to decrease the budget of the operation and maintenance sector. The strategies that the sector has been developing in the last decade consist of using higher winds and bigger turbines.

The objectives of the HYDROBOND project also targets to reduce the maintaining costs of offshore wind turbines. The coatings developed in the project will act as a passive anti-icing method minimizing ice accretion and therefore increasing the reliability and operational life of the blades and other components. Furthermore, the enhanced bond strength and the ability to keep the anti-icing properties even when wear phenomena occurs will contribute to reduced maintenance needs. The new depeloped process is intended to be portable which will allow in situ repairs.
