MingYang Smart Energy, a Chinese offshore wind turbine manufacturer, has unveiled its latest turbine prototype that can operate even in strong typhoons. With a capacity of 18 MW, it is the world's largest wind turbine to date, Interesting Engineering reported on December 14.

With its manufacturing base in Shanwei, MingYang on December 13 introduced the MySE18.X-20 MW offshore wind turbine. The turbine’s design is an evolution of the 14- to 16-MW versions the company has already produced and deployed. According to them, the turbine has an ultra-lightweight modular design and offers high efficiency.

The diameter of the turbine ranges from 260 - 292 m depending on the power level (18 - 20 MW) and the swept area is equivalent to 9 football fields. The annual capacity of the turbine is 80 million kWh in the Guangdong region, helping to provide electricity to 96,000 households and reduce 66,000 tons of CO2.

MingYang Smart Energy claims that the new turbine design can be deployed in areas with medium to high winds. In addition, the turbine is equipped with active storm protection technology, allowing the device to withstand a Category 17 typhoon. The company did not disclose the details of the technology, but this means that the turbine can withstand winds of 56 - 61 m/s, the strongest typhoon winds ever recorded in the world. However, the MySE18.X-20 MW turbine may soon be dethroned. Earlier this October, MingYang introduced a design for a 22 MW turbine with blades as long as the Eiffel Tower.

As the world moves away from fossil fuels, wind and solar power plants will play a central role in meeting electricity needs. While solar farms are limited by the fact that they cannot produce energy at night, turbines can operate all day, although their output can fluctuate. Over the years, wind turbines have become larger and can produce more electricity with a single rotation. Moving turbines offshore frees up land for farms.
