The EcoSwing Story

This is the story of EcoSwing - the world’s first grid connected superconducting generator operating in a wind turbine. In this video we show our venture from basic concepts to operation of this cutting edge technology. This exciting project was guided by team spirit from start to end.

MISSION ACCOMPLISHED—First Superconductive Generator Successfully Operated on Turbine

EcoSwing has now ended on schedule. On one hand we are quite sad to finish this inspiring project, on the other hand we are proud to announce a number of groundbreaking successes. Just in short:

  • EcoSwing generator and power converter reached target range +3 MW
  • More than 650 h of grid operation producing power
  • Automated unattended operation enabled
  • More than 7 months of stable and reliable cryogenic system operation
  • Superconducting rotor coils showed great performance and reliability
  • According to schedule EcoSwing has been switched-off for decommissioning on 25.4.2019
  • Compressors and cold heads have been switched-off for warming-up.

We are currently preparing technical articles which you will be able to access from this news section. Also you are certainly wondering what the next step after a successful EcoSwing might be. Stay tuned for more!

PS: The picture on top gives a glimpse under the hood of EcoSwing. It shows inspection of the cooling equipment for the superconductive rotor.

On the Experience of EcoSwing Operation

The EcoSwing superconducting generator is now grid connected and supplying power on a regular basis. First households in Denmark can claim "Powered by Superconductivity". The superconductive generator technology has proven able to operate in a 3 MW Direct Drive wind turbine with all the real impacts present in a wind turbine operational environment.

Jesper Hansen of Envision Energy sums it up in his concise manner "The generator is working as expected". This 5th in series video clip will give you an update into the state of this exciting project.

EcoSwing is the Drivetrain of the Year 2018. Gold Medal from Windpower Monthly

This year's Turbine of the Year Award in the Drivetrain Category went to EcoSwing. To be precise we got the GOLD MEDAL! This is truly fantastic!

EcoSwing has been bestowed by the well-known trade journal Windpower Monthly. Eize de Vries highlighted the journal's motivation in "vastly reduced material usage has contributed to making superconducting technology competitive with conventional electric machines". According to Windpower Monthly this fits well to the sector trend of higher rated turbines and changing grid demands.

As we see it—there is little to add.

Windpower Monthly is the leading news magazine of the international wind energy business, publishing non-stop since 1985. You can read the entire article on the web site of  Windpower Monthly.

Worlds first superconducting wind turbine on grid and producing power

After the successful installation of the EcoSwing generator in Thyborøn, the project has progressed further. Now commissioning has advanced to a level where this compact and lightweight generator is grid connected and producing power.

The EcoSwing project has had its "Kitty Hawk Moment" at 14:00h on 6 December 2018 when Envision's direct drive turbine produced net power to the grid. Soon thereafter the engineers could ramp the EcoSwing to 1 MW and beyond.

Thus EcoSwing claims the title as world's first wind turbine with a grid connected superconducting generator. Test and verification is in progress to capture new knowledge on operation with superconductive technology.
