Progress in the principle of superconducting energy storage

What is superconducting magnetic energy storage system (SMES)?

Superconducting magnetic energy storage system (SMES) is a technology that uses superconducting coils to store electromagnetic energy directly.

What are the advantages of superconducting energy storage?

Superconducting energy storage has many advantages that set it apart from competing energy storage technologies: 1. High Efficiency and Longevity: As opposed to hydrogen storage systems with higher consumption rates, SMES offers more cost-effective and long-term energy storage, exceeding a 90% efficiency rating for storage energy storage solutions.

What are superconductor materials?

Thus, the number of publications focusing on this topic keeps increasing with the rise of projects and funding. Superconductor materials are being envisaged for Superconducting Magnetic Energy Storage (SMES). It is among the most important energy storage systems particularly used in applications allowing to give stability to the electrical grids.

How to design a superconducting system?

The first step is to design a system so that the volume density of stored energy is maximum. A configuration for which the magnetic field inside the system is at all points as close as possible to its maximum value is then required. This value will be determined by the currents circulating in the superconducting materials.

Why do superconductors need a power conversion system?

When energy needs to be released, the energy stored in the magnetic field can be quickly output through the power conversion system, ensuring a stable power supply. Since superconductors do not generate resistance losses in the zero resistance state, SMES systems have extremely high energy efficiency and fast response capability.
