摘要

The tidal energy company Nova Innovation has completed a project to manufacture a new direct drive tidal turbine. The machine eliminates the need for a gear box, reducing the cost of the energy produced by 30 per cent. In 2016, the company secured €2.25 million of funding from the European Commission's SME Instrument to develop the direct drive tidal turbine, known as D2T2. Three years on, the turbine has been manufactured, is commercially ready, and about to be deployed at Nova's tidal array in Shetland, Scotland. In addition, a deal to export 15 of the turbines to Canada has been secured. The design of the new machine drew on experience from Nova's existing turbines, which have been operating in Shetland for the past four years, and have succeeded in increasing efficiency and reducing costs. Based on lessons from the wind industry, this was achieved by eliminating the need for a gearbox, significantly improving the performance of the device. Fewer moving parts in the turbine increase its reliability and extend the period between service intervals from one year to more than two years.
