Superconducting energy storage operating temperature

What is a superconducting magnetic energy storage system?

Superconducting magnetic energy storage (SMES) systems can store energy in a magnetic field created by a continuous current flowing through a superconducting magnet. Compared to other energy storage systems, SMES systems have a larger power density, fast response time, and long life cycle.

What is a high-temperature superconductor?

This breakthrough, which earned them the Nobel Prize in Physics, laid the foundation for high-temperature superconductivity research. To this day, copper oxides remain the only superconducting oxides that function at temperatures above 30 K, or about minus 243 dec C, under ambient pressure, without requiring lattice compression.

Can a copper-free high-temperature superconducting oxide work under ambient pressure?

The research breakthrough was published in the scientific journal Nature on 20 March 2025. Expanding the frontier of high-temperature superconductors "This is the first time since the Nobel-winning discovery that a copper-free high-temperature superconducting oxide has been found to function under ambient pressure," emphasised Prof Ariando.

What is the difference between SMEs and other energy storage systems?

Compared to other energy storage systems, SMES systems have a larger power density, fast response time, and long life cycle. Different types of low temperature superconductors (LTS) and high temperature superconductors (HTS) are compared.

Are superconductors energy efficient?

Modern electronics generate heat and consume energy during operation. Superconductors, however, possess a unique property known as the zero-resistance state, which eliminates energy loss due to electrical resistance. In theory, this makes them ideal for modern electronic applications, addressing the world's growing energy demands.

Is there a superconductor beyond copper oxides?

Nearly four decades after the discovery of copper oxide superconductivity, which earned the 1987 Nobel Prize in Physics, the NUS researchers have now identified another high-temperature superconducting oxide that expands the understanding of unconventional superconductivity beyond copper oxides. The promise of superconductors
