Superconducting materials hold great potential to bring radical changes for electric power and high-field magnet technology, enabling high-efficiency electric power
Superconductivity is a set of physical properties observed in certain materials where electrical resistance vanishes and magnetic fields are expelled from the material. Any material exhibiting these properties is a superconductor.Unlike an ordinary metallic conductor, whose resistance decreases gradually as its temperature is lowered, even
Superconducting magnetic energy storage (SMES) is a device that utilizes magnets made of superconducting materials. Outstanding power efficiency made

We have been developing a superconducting magnetic bearing (SMB) that has high temperature superconducting (HTS) coils and bulks for a flywheel energy storage system (FESS) that have an output capability of 300 kW and a storage capacity of 100 kW h (Nagashima et al., 2008, Hasegawa et al., 2015) [1,2]. The world largest-class
This paper presents a novel high-speed alternating current (AC) homopolar motor/generator design using stationary ReBCO excitation windings. Compact, lightweight, high-efficiency motors and generators are sought for a multitude of applications. AC homopolar synchronous machines are an ideal choice for such applications as these
The structure of the SMES is shown in Fig. 17 [53,95]. The energy is stored in a superconducting electromagnetic coil, which is made of niobium-titanium alloys at liquid helium (or super liquid
Superconducting magnetic energy Storage (SMES) combines the high-density and high-efficiency energy storage characteristics of superconducting magnets and the millisecond
Obviously, the energy storage variable is usually positive thanks for it is unable to control the SMES system by itself and does not store any energy, it can be understood that the DC current is usually positive. Thus, the energy storage variable is usually positive for a finite maximum and minimum operating range, namely, expressing
Electric distribution systems face many issues, such as power outages, high power losses, voltage sags, and low voltage stability, which are caused by the intermittent nature of renewable power generation and the large changes in load demand. To deal with these issues, a distribution system has been designed using both short- and long-term energy
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
Compared with an energy efficiency of 45 - 60% in the MW-class conventional heater, the energy efficiency of this HTS DC induction heater can achieve up to 80.6% based on test results.

Pseudocapacitance. In electrical energy storage science, "nano" is big and getting bigger. One indicator of this increasing importance is the rapidly growing number of manuscripts received and papers published by ACS Nano in the general area of energy, a category dominated by electrical energy storage. In 2007, ACS Nano ''s first year
