SuperNode bets on superconductors to solve our renewable energy transmission problem

We have achieved strong political consensus, especially in Europe, that renewable energy is the way to go as we head towards a net zero future. And in that future, our power grid will be put to the test as these intermittent and rather variable energy sources, namely wind and solar, move through it.

Making this work in practice, across a continent like Europe, requires a bit of a technology upgrade, according to SuperNode’s Christian Kjær, Chief Public Affairs Officer for the company.

“SuperNode’s mission is to develop and market innovative transmission technology based on superconductors that can carry vast amounts of energy over long distances in interconnected grids. This requires less infrastructure, fewer materials and not as much space,” explains Kjær.

According to SuperNode, the current transmission grid technology is insufficient to move around the quantities of energy that we’ll need in our soon-to-be weather-based energy system. Superconductors are SuperNode’s answer to this complex energy scenario. But superconductors aren’t exactly a part of people’s everyday reality.

“Most people grasp that superconductivity in transmission means that you can move power over very long distances with zero resistance and therefore, no losses,” explains Kjær. “However most also believe that the technology sounds too good to be true and so it must be something for the distant future, like nuclear fusion or personal space crafts.”

But the future is coming, and fast, for SuperNode. The company aims to be the first to achieve a full-scale demonstration project of a subsea transmission cable based on superconductor technology in the next five years. And in just 10 years, SuperNode says that superconductor technology will span the globe, making it less science fiction and far more mainstream.
