TIDAL TURBINE GENERATOR TRIAL

The middle pod, which sits several feet higher than those on either side, holds a connector for the power transmitter as well as a device to adjust buoyancy-that is, to enable the array to move to deeper or shallower water and thus capitalize on variations in the current’s strongest spots. The system is made up of three connected cylindrical pods. The 330-ton turbine is designed to harvest energy from ocean currents (as opposed to tides). This setup works well for generating high quantities of power with multiple turbines Sihwa Lake has 10 turbines and La Rance has 24. The biggest tidal power plant in the world is Sihwa Lake station in South Korea, which has a capacity of 254 megawatts (MW), followed by a 240MW station in La Rance, France (this is also the world’s oldest tidal plant, built between 1961-1966).īoth these plants use what’s called a barrage, which is a long underwater wall (the barrage at the La Rance plant, for example, is 476 feet long) with gates that open and close with the tides in a way that capitalizes on their energy production potential. Ocean turbines are essentially an underwater version of wind turbines, functioning much the same way the movement of water-whether from tides or currents-turns blades that are attached to a rotor, turning the rotor and powering a generator.

The trial was deemed a success, and detailed in a report published by Bloomberg recently. Meanwhile, a similar ocean turbine called Kairyu was already in the water off the coast of Japan, undergoing a three-year trial to harness the power of deep ocean currents. The system was expected to generate enough electricity to power around 2,000 Scottish homes and offset 2,200 tons of CO2 annually. In 2019, its Agency for Natural Resources and Energy said the country was 'largely dependent on fossil fuels' like coal, oil and liquefied natural gas.A little over a year ago, a Scottish company called Orbital Marine Power was getting a two-megawatt tidal turbine up and running in the North Sea. Work still needs to be done for the country to achieve its aims, however. By 2030, Japan wants a 26% reduction in greenhouse gas emissions compared to 2013. Last October, Prime Minister Yoshihide Suga said the country would target net zero greenhouse gas emissions by the year 2050.

The International Energy Agency describes marine technologies as holding 'great potential' but adds that extra policy support is required for research, design and development in order to 'enable the cost reductions that come with the commissioning of larger commercial plants.'įor its part, Japan says it wants renewables to make up 22% to 24% its energy mix by 2030. and Australia - is based around the idea of using rubber membrane 'cells' which are filled with air and fitted to a structure submerged underwater.Īccording to a video from the company outlining how its system works, when waves pass over the system, its 'flexible rubber membrane design pumps air through a turbine to generate electricity.' In simple terms, the tech developed by Bombora - which has offices in both the U.K. The collaboration between the Tokyo-headquartered MOL and Bombora will focus on finding possible locations for the latter's mWave system, as well as hybrid projects which combine mWave and wind energy.
