Marine Current Turbines (MCT) evolved from a pioneer to a technology leader in horizontal-axis marine current turbines and has 25 employees. In February 2010, Siemens acquired a minor stake in the British company and thus entered the marine tidal current sector. Ocean power is emerging with strong growth rates driven by global CO2 reduction commitments. Until 2020, experts anticipate double-digit growth rates for the ocean power business. Based on further estimates the global potential for power generation using tidal power plants is 800 terrawatt-hours (TWh) per annum. This equates to 25 percent above the total power demand in Germany and between 3 and 4 percent of power consumption worldwide.
Andrew Tyler, chief executive officer of MCT, said: “Through the expansion of the partnership with Siemens, we have further strengthened our position in the tidal energy market. We have the increased backing of a major industrial player in Siemens, which is essential to support the commercialisation of our proven technology.” MCT already successfully implemented its first commercial-scale demonstrator project SeaGen in Strangford Lough in Northern Ireland. Since November 2008, two axial turbines with a combined capacity of 1.2 MW have been feeding power into the grid to supply about 1,500 homes.
Marine current turbines generate electricity by utilising tidal current flows. The SeaGen turbine is fixed on a structure and is driven by the flow of the tides. This technology is effectively similar to a wind turbine, with the rotor blades driven not by wind power but by tidal currents. Water has an energy density much higher than that of wind. A key advantage is that the generated power is precisely predictable in the tidal cycle.
Marine current turbines are part of Siemens’ Environmental Portfolio. In fiscal 2010, revenue from the Portfolio totalled about EUR28 billion, making Siemens the world’s largest supplier of ecofriendly technologies. In the same period, our products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by 270 million tonnes, an amount equal to the total annual CO2 emissions of the megacities Hong Kong, London, New York, Tokyo, Delhi and Singapore.
