The Bristol Channel is in the Southwest of England and supports thriving economic ports, Highbridge and Bristol. It also has one of the largest tidal ranges in the world at over 14m. This offers the largest resource for tidal energy in the UK. Tidal power offers a pollution-free, natural renewable energy source that harnessed kinetic energy produced from the rising and falling of the tides. The energy potential of a tidal barrage is determined by the height of the tide. The higher the tide, the more kinetic energy produced when it falls, the longer the turbine will spill generating greater power. There are various proposed barrages to harness the tidal power potential in the Bristol Channel. Each differs in length, size and location, with some being barrages stretching across the channel and other proposed projects being lagoons. Each proposal also differs in energy potential and price. This poster will explore the feasibility of tidal power in the Bristol Channel, the reason for building a barrage in that location, the potential energy, estimated costs of each barrage and the effect on marine and economic activity.
