Description

The presentation will review the background to the need for renewable energy, by outlining the benefits of predictable and reliable energy from tidal resources. The impacts associated with the drivers of climate change, population growth, increasing urbanisation and the sustainable development goals will be discussed, along with the increasing need for more electricity in the future as we move to electrification of transport, heating etc. The UK tidal energy resource will then be discussed, and comparisons made for tidal stream and tidal range resources, highlighting the considerable opportunities of acquiring tidal energy from the Severn Estuary and Bristol Channel; an estuarine basin with the second highest tidal range world-wide. Details will then be given of the typical minimum requirements for tidal stream technology, with an explanation as to why the Severn Estuary and Bristol Channel is generally not an effective basin for such technologies. In contrast the basin is ideal for tidal range technologies (i.e. barrages and lagoons) from an engineering and tidal energy perspective, and comparisons will be made with existing operational schemes, such as La Rance in France and Shiwa in Korea.
