A Norwegian company, World Wide Wind (WWW), announces major advances in offshore wind energy with the launch of its first floating counter-rotating wind turbine prototype. This innovative technology could revolutionize wind energy production at sea, paving the way for 400 meter wind turbines. height (Height has several meanings depending on the field addressed.), each producing 40 megawatts, or double the capacity of the largest current wind turbines.
The concept of this wind turbine is radically different from that of conventional wind turbines. Instead of using propellers that rotate around a horizontal axis (Horizontal is an orientation parallel to the horizon, and perpendicular at the…), the WWW wind turbine is equipped with a vertical axis (The vertical (rare), or vertical style, is a style of musical writing consisting of…). Its design is innovative, with two turbines mounted on the same axis. The upper turbine is connected to the rotor, while the lower turbine is connected to the stator. This configuration makes it possible to double the speed (We distinguish:) of relative rotation of the blades, thus increasing the efficiency of energy production (In the common sense, energy designates everything that allows us to carry out work, make energy, etc.) .
In addition, the blades are tilted at an angle of 45 degrees to the vertical axis, which reduces the speed at the blade tips and the wake effect, all (All inclusive as a whole of what exists is often interpreted as the world or…) by allowing wind turbines to be installed closer to each other. This provision would also reduce the impact on local wildlife. The generator is positioned underwater, acting as a counterweight to maintain the wind turbine in a vertical position, even under the effect of the wind.
This simple approach could significantly reduce production costs, with the goal of achieving a cost of $50 per megawatt hour. The first 19 meter high prototype is still limited to an output of 30 kilowatts, but this is the very first full-scale test. WWW plans to test a second, larger prototype capable of generating 1.2 megawatts in 2025, and hopes to commercialize a 24 megawatt model by 2030.
The potential of this technology is enormous, as it could reduce the costs of producing offshore wind power, while increasing production capacity. Counter-rotating floating wind turbines could thus be the future of offshore wind energy, opening the way to gigantic wind turbine fields capable of providing clean energy (Clean energy or green energy is a source of energy whose exploitation only produces…) and affordable on a large scale (Large scale, also called aerial scale or auto scale, is a…).
