Superconducting energy storage breakthrough

Could a new discovery unlock the microscopic mystery of high-temperature superconductivity?

Credit: SciTechDaily.com An international team of scientists has made a new discovery that may help to unlock the microscopic mystery of high-temperature superconductivity and address the world’s energy problems.

Are high-temperature superconducting magnets suitable for fusion power plants?

A comprehensive study of high-temperature superconducting magnets built by MIT and Commonwealth Fusion Systems confirms they meet requirements for an economic, compact fusion power plant.

How does a superconducting magnet work?

Like virtually all electrical wires, conventional superconducting magnets are fully protected by insulating material to prevent short-circuits between the wires. But in the new magnet, the tape was left completely bare; the engineers relied on REBCO’s much greater conductivity to keep the current flowing through the material.

Are high-temperature superconductors economically viable?

Since the discovery of high-temperature superconductivity 1 at above liquid nitrogen temperature 2 in cuprates, there have been enormous efforts to create practical superconductors that meet industry needs at sufficiently low cost to be economically viable.

How do high-temperature superconductors achieve zero electrical resistance?

While scientists have known about high-temperature (still very cold) superconductors known as “cuprates” for decades, they haven't quite solved the mystery of how they achieve zero electrical resistance at temperatures much higher than traditional superconductors.

What is a superconducting material?

In addition, the superconducting material, which is a complex quaternary oxide, is one of the most chemically advanced materials currently in industrial production. High-performance coated conductors require conductor flexibility, shunting, strengthening and insulating layers and post-engineering.
