|CWR Presents: : Theory of removing energy from tidal streams – with a focus on the UK
Tidal stream energy, which involves placing tidal turbines in locations with large tidal currents, is receiving significant attention as a potential renewable energy source in the United Kingdom. Recent estimates suggest that tidal stream energy could supply between 5-10% of the UK’s current electricity demand.
In this talk we begin with a short discussion of where tidal currents are large around the world and why. We then discuss the theory of tidal stream energy. First a simple analytical model for a row of tidal turbines (i.e. a fence) is presented, which provides an estimate of the efficiency of a tidal turbine in terms of the energy it removes from a tidal current. The model also highlights several distinctions between wind turbines and tidal turbines.
Second we discuss how much energy can be removed by a fence of tidal turbines deployed within a tidal strait, oscillating bay and close to the tip of a coastal headland. These particular sites represent the variety of actual locations around the UK with fast moving tidal streams.
To finish, the likely prospect of tidal stream energy in Australia is discussed.
