Denmark's Monster Wind Turbine Just Smashed the 24-Hour Record For Energy Production

By George Dvorsky on at

A 720-foot-tall wind turbine featuring 35 tonne blades has just set a new world record, producing a whopping 216,000 kWh of energy over a span of 24 hours. That’s enough to power an average American household for twenty years.

The giant turbine, located off the coast of Østerild, Denmark, is setting a new standard for wind power. MHI Vestas Offshore Wind—a joint venture between Vestas Wind Systems and Mitsubishi Heavy Industries—revealed the 9 megawatt (MW) prototype in late 2016. The machine, named V164-8.0 MW, is a revved up version of the company’s 8 MW model, allowing it to produce even more juice under favourable wind conditions.

On December 1st, the machine produced 215,999.1 kWh over a 24 hour period, a new record for a commercially-available offshore wind turbine. Given the success of this test, the company is hoping to increase the energy production of its customer’s fleets, but with fewer turbines and at a lower cost. The new machine is part a broader push to get more bang for the buck out of offshore turbines in general.

Like other state-of-the-art models, the V164-8.0 MW is an impressive sight to behold. Each of its three blades measures 80 metres in length, which is equivalent to nine city buses. The blades weigh in at 35 tonnes a piece, and sweep a total area measuring 21,125 square metres—roughly the same size as the London Eye. The hub is 140 metres high, and when a blade is fully extended overhead the structure stands 220 metres tall.

Denmark continues to be a leader in the field of offshore wind power. Back in 2015, the country’s wind output exceeded national demand. That impressive accomplishment notwithstanding, this is still a small industry in Europe, and it’ll be a long time—if ever—before wind power solves our energy woes. As efficient and clean as wind power is, this particular form of renewable energy is unlikely to topple solar power, which is starting to make huge inroads, especially in the US, China, and Middle East. Still, as the broken record indicates, offshore wind undoubtedly has a powerful potential. [MHI Vestas via Digital Trends]
