This is how a WORLD RECORD looks like: we made it! 190 kA!

It was long ago we posted news here, we know. But we were busy producing results. It took us 5 years – and now we present a breakthrough in superconductivity: 190 kA achieved for the first time – A milestone for the industry.

For five years, engineers, scientists and technicians have been working on the DEMO200 project for developing an efficient power supply for high-current applications with superconductors.

The goal: to make energy-intensive aluminium production more efficient and to reduce operational costs.

Now it has come true: the decisive test was successful at the Trimet aluminium plant in Voerde. After cooling down the system to 77 Kelvin (-196°C), the power supply maintained a total current of 170 kA over several hours and reached a peak of 190 kA.

We are very happy about having achieved this important milestone together with our partners and would like to thank:

But this is just the beginning. Now we go for the real thing:
The next step is the SuprAl project near Hamburg. Here, a 200 m long return conductor with 200 kA is to be replaced by a superconducting system. This would be the ultimate proof that Superconductors are industry ready.

You see why we love to be pioneers!
