Description Tidal energy is recognised as the marine renewable technology having the greatest potential to achieve commercial acceptance and wide scale deployment. This project will investigate the different types of tidal energy architecture, analysing the quantities of power which can be delivered from different technology architectures and how they can be configured into an array. For each type and scale of array development the levelised cost of energy delivered will be calculate and used to identify whether it is likely technology convergence will ever be realised in the same context that it has in the wind energy sector. Key Objectives Establish the performance characteristics and envelopes of different tidal technology architecture Establish the best array configurations for each type of architecture to maximise energy extraction
