European project led by Scottish tidal developer demonstrated cost savings in generating renewable tidal energy with new technology.
The European EnFAIT (Enabling Future Arrays in Tidal) Horizon 2020 project, led by one of Scotland's leading tidal developers, has achieved discoveries that have the potential to redefine the limits of what can be achieved by tidal energy across the world. The project, which had an investment of US$22 million, brought together seven partners, including Scottish tidal developer Nova Innovation, responsible for the world's first offshore tidal array – the Shetland Tidal Array and the Offshore Renewable Energy (ORE) Catapult. , with the aim of reducing the cost of tidal energy. EnFAIT Horizon 2020 began in 2017 and brought cost reduction, innovation and industry learnings in last six years.
The EnFAIT Horizon 2020 project, led by one of Scotland's leading tidal developers, aimed to reduce the cost of tidal energy, achieving a 40% reduction in tidal turbine costs. The project's findings could significantly impact the sector, bringing benefits to both the development of renewable energy and the economy in general. This reduction in tidal turbine costs represents an important advancement for the tidal energy industry and its viability in the competitive energy market.
Horizon 2020 Project: New Tidal Turbine Technology
During the project, Nova Innovation installed three new 100 kW direct drive turbines and a subsea center alongside the three existing turbines on the Shetland Tidal Array. For the first time, the effects of wake between turbines in a real-world environment have been analyzed to identify the ideal spacing between turbines in an array and the effect this has on power generation. The data collected helped to calibrate the computational modeling which will be invaluable for future tidal energy projects.

Cost Reduction and Tidal Development in the Horizon 2020 Project
Simon Forrest, CEO of Nova Innovation, added: 'EnFAIT has been an incredibly successful project. We reduced costs by 40%, doubled the size of the world's first offshore tidal pool and extended turbine maintenance intervals to two and a half years; they are all remarkable achievements. These are crucial steps to building investor confidence and making tidal energy bankable.'
Tidal Energy Technology and New Turbines
The seven EnFAIT partners from across Europe were Nova Innovation, ORE Catapult, IDETA, RSK, SKF, Wood and The University of Edinburgh.
