To meet future energy demands, electricity grids in Europe will need to be updated and expanded to ensure increased transmission capacity. To do this, 10 partners are working on a superconducting cable demonstrator as part of the Best Paths project, which consists of five demonstration projects and involves 40 partners across Europe. The superconducting demonstrator is exploiting the potential of magnesium diboride (MgB2) for superconducting cables. The 20-metre long MgB2 prototype cable is intended to comply with the power network and will be operational at currents of 10 kilo-amperes with voltage of 320 kilovolts.
