According to Hempel, they provided coatings to protect the Orbital O2 tidal energy turbine, the world’s most powerful tidal turbine. O2 is set to operate at the European Marine Energy Centre (EMEC) in the Orkney Islands in the UK. Around the islands of Orkney, tidal currents can reach over four metres per second, making them some of the strongest in the world. To harness this energy, Orbital’s O2 comprises two 1MW turbines, which together create a 600 m2 rotor area and can generate 2MW of clean, predictable energy. O2 is capable of supplying enough energy to power around 2,000 UK homes.
Hempel have been involved in the project since Orbital’s prototype SR2000 turbine was built in 2015. As well as high-performance anti-corrosion coatings, Hempel has supplied Hempaguard X7 for the O2’s turbine rotor blades. Hempaguard X7 was developed specifically to combat biofouling, such as algae and barnacles.
According to Andrew Scott, CEO of Orbital, collaborations with companies like Hempel have been key to the O2’s development. “We rely heavily on our supply chain to help deliver our pioneering technology such that it exceeds expectations, and in that regard, we are delighted to continue our relationship with Hempel for our novel coating applications”.
