The Lànstrøm tidal turbine, which will be used at the three Scottish tidal energy generation sites The Lànstrøm tidal turbine, which will be used at the three Scottish sites ScottishPower Renewables has identified the Pentland Firth, the Sound of Islay, and the North Antrim coast off Northern Ireland - as the most suitable for the underwater turbines. Each site will have between five and 20 1MW machines which could lead to a combined output of 60MW - enough to meet the energy needs of 40,000 homes. Environmental impact assessments are already under way and ScottishPower expects to have planning applications submitted to the Scottish Government and Northern Irish Assembly by next summer and the turbines could be online by 2011 producing the world's largest tidal stream project. All will use the Lànstrøm tidal turbine, claimed to be the most advanced tidal turbine in the world, following four years of testing off Hammerfest, the northernmost town in the world, in Norway. The Lànstrøm is described as an underwater wind turbine but with much shorter blades which turn more slowly. The units are anchored to the sea bed and aligned to the tidal flow. advertisement Unlike the wind, tides are entirely predictable and operators will quickly know how much power the turbines will generate. The experimental turbines will each have the capacity to generate about 1MW of power but the company eventually wants to see much bigger arrays capable of generating 50MW-100MW. The total global tidal power resource has been estimated at 150bn kilowatt-hours per annum with the UK having almost a 10 per cent share representing 13bn kilowatt-hours. More than 80 per cent of the potential is located in Scottish waters. Tidal power is an entirely clean and renewable source of energy and could play a major role in helping the UK's meet its CO2 emissions target. The Scottish Government is a keen supporter of tidal and wave power and claims it is uniquely placed to become a world leader in the technology. "We are home to the meeting point of two powerful seas and the Pentland Firth has been described as the 'Saudi Arabia of tidal power," said a spokesman. ScottishPower is part of Iberdrola, the biggest generator of renewable energy in the world. Iberdrola says it will invest £800m on new green energy projects in the UK in the next 2 years. ScottishPower has committed to increase its installed renewable generation capacity to 1800MW by 2012. A new company, Hammerfest Strøm UK, has been set up to manufacture the turbines in Scotland exploiting underwater expertise gleaned in the North Sea oil industry. Director Keith Anderson said: "The rapid technological advance of tidal power has been startling and is now allowing us to progress plans for a substantial project delivering major environmental and economic benefits. "Tidal power is completely renewable, being driven by the gravity of the sun and moon, with no carbon dioxide emissions, plus the added benefit of being entirely predictable. "Scotland has the best tidal resources in Europe with the Pentland Firth alone containing enough tidal energy to meet a third of Scotland's power requirements." http://www.telegraph.co.uk/earth/main.jhtml?xml=/earth/2008/09/29/eatidal129.xml
