New Wind Turbines Blow Away Old Power Generation Records

Wind energy technology is rapidly evolving and contributing ever more power to the global grid.

Renewable energy has been steadily expanding its market share over the past decade, and as technologies have improved and costs have come down, output has gone up — way up. The record-breaking test run of a new giant wind turbine in Denmark is another indicator that green energy is ready to become a dominant force in the global energy mix.

The new 9 MW prototype turbine, called MHI Vestas Offshore Wind, is a joint venture between Vestas Wind Systems and Mitsubishi Heavy Industries. The turbine is 722 feet tall, has 38-ton blades that are 263 feet long. In a December 2016 test on the coast of Østerild, Denmark, the huge turbine generated nearly 216,000 kWh in a 24-hour period, breaking the previous record for energy generation by a commercially available offshore wind turbine. That’s enough energy to power the average American household for 20 years.

“We are confident that the 9 MW machine has now proven that it is ready for the market and we believe that our wind turbine will play an integral part in enabling the offshore industry to continue to drive down the cost of energy,” said CTO Torben Hvid.

Vestas CEO Anders Runevad said that wind energy will only continue to grow. “Wind continues to increase its competitiveness in the energy space, and we take good advantage of that.”

Offshore wind investments in Europe hit 18.2 billion euro last year, according to statistics from industry body WindEurope, and covered more than 10 percent of the energy needed in Europe in 2016. Investment in offshore wind technology has tripled in the past five years.

Furthermore, that technology is rapidly changing. While much of the wind energy produced in Europe comes from massive turbines and large-scale wind farms, upcoming innovations will decrease the size needed to generate electricity. New smaller, quiet wind turbines are being developed for individual and small-scale use. Inergys, a French start-up supported by EU climate innovation initiative Climate-KIC, is making turbines that power individual buildings. In Britain, a company called NVT group has designed mini-turbines that attach to lamp posts and send the power they generate straight to the grid. Another mini-turbine concept resembles cottonwood trees with spinning leaves and branches that generate power. The researchers at Iowa State University who created it were inspired by cell phone towers designed to look like trees to bring a more aesthetically pleasing design to the urban environment.
