OpenHydro designs, manufactures and installs marine turbines to generate renewable energy from tidal streams. OpenHydro is now preparing to enter the industrial supply phase of its development where it will deploy arrays of turbines on the seabed to generate energy silently, invisibly and with no impact on the environment. The innovative features of their design include the open-centre turbine technology, a low maintenance design with only one moving part and development of a safe and economical method for deploying and recovering the turbines, allowing them to be fully deployed in less than 6 hours. OpenHydro were the first company to deliver tidal energy to the UK National Grid and they will be deploying a 7 turbine array in 2018. This will be a world first and will act as a showcase to demonstrate the potential of tidal energy.
