The challenge

To accelerate the clean energy transition by keeping the electricity grid stable under a large input of fluctuating solar and wind energy.

The solution

We collaborate with the TUDelft. Research into a more stable dc/dc converter has been performed together with ESA.We don’t have any customers yet.
