Superconductor busbars have reached industrial readiness. Superconductors are conducting direct current with extremely high densities of more than 500A/mm² with zero losses. Due to their low space requirements, high current carrying capacity and utmost efficiency superconductor busbars will find their place in the aluminium industry.
The paper introduces the technical basis of superconductors and continues with technical and economic advantages. Five different usecases are illustrated with information about technical limits, energy efficiency and economic performance. Experiences out of installations are shared.
The presented usecases are: Main busbars between rectifiers and potroom; Interconnection busbars between potlines and to standby rectifiers; Magnetic field compensation; DC connection between potline and power plant or grid connection point; Superconducting magnetic field shielding, permanent or mobile
Investment costs are indicated as well as costs for maintenance, operation and total cost of ownership for various timelines. A breakeven can be achieved in 4 years.
