A design process for HTS DC cables was developed for high current applications. Based on the design process, a 35 kA HTS DC cable demonstrator was developed. The superconducting elements of the demonstrator were manufactured and tested individually at 77 K. Afterwards, the demonstrator cable was assembled and tested at 77 K. The assembled demonstrator successfully reached 35 kA at 77 K and self field conditions.

High-temperature superconductors have distinct advantages compared to conventional conductors. Below their critical temperature, superconductors have immeasurably low ohmic losses. To maintain the superconducting state, superconductors require constant cooling. This study aims at identifying the environmental impacts of the application of superconductors in future grid technologies such as superconducting power cables.

High temperature superconductors (HTS) offer many advantages through their application in electrical systems, including high efficiency performance and high throughput with low-electrical losses. While cryogenic cooling and precision materials manufacture is required to achieve this goal, cost reductions without significant performance loss are being achieved through the advanced design and development of HTS wires, cables and magnets, along with improvements in manufacturing methods. This book explores the fundamental principles, design and development of HTS materials and their practical applications in energy systems. Part one describes the fundamental science, engineering and development of particular HTS components such as wires and tapes, cables, coils and magnets and discusses the cryogenics and electromagnetic modelling of HTS systems and materials. Part two reviews the types of energy applications that HTS materials are used in, including fault current limiters, power cables and energy storage, as well as their application in rotating machinery for improved electrical efficiencies, and in fusion technologies and accelerator systems where HTS magnets are becoming essential enabling technologies. With its distinguished editor and international team of expert contributors, High temperature superconductors (HTS) for energy applications is an invaluable reference tool for anyone involved or interested in HTS materials and their application in energy systems, including materials scientists and electrical engineers, energy consultants, HTS materials manufacturers and designers, and researchers and academics in this field.

This work presents the development and application of high-speed fluorescent thermal imaging for quench analysis in high-temperature superconductors (HTS). Using a fluorescent coating, with a temperature-dependent light emission, temperature changes can be calculated over 2D surfaces. The technique uncovered peculiar transient effects in novel HTS tape architectures and also helped to verify and better understand hot spot development in both insulated and non-insulated, HTS–wound pancake coils.

The technology of high temperature superconductivity has gone beyond mere scientific curiosity and into the manufacturing environment. Single lengths of multifilamentary wire are now produced that are over 200 meters long and that carry over 13 amperes at 77 K. Short-sample critical current densities approach 5 x 104 A/cm2 at 77 K. Conductor requirements such as high critical current density in a magnetic field, strain-tolerant sheathing materials, and other engineering properties are addressed. A new process for fabricating round BSCCO-2212 wire has produced wires with critical current densities as high as 165,000 A/cm2 at 4.2 K and 53,000 A/cm2 at 40 K. This process eliminates the costly, multiple pressing and rolling steps that are commonly used to develop texture in the wires. New multifilamentary wires with strengthened sheathing materials have shown improved yield strengths up to a factor of five better than those made with pure silver. Many electric power devices require the wire to be formed into coils for production of strong magnetic fields. Requirements for coils and magnets for electric power applications are described.

Mitigating climate change, clean environment, global peace, financial growth, and future development of the world require new materials that improve the quality of life. Superconductivity, in general, allows perfect current transmission without losses. This makes it a valuable resource for sustainability in several aspects. High-temperature superconducting (HTSC) materials will be crucial for sustainable everyday applications and more attractive for the United Nations’ SDGs. Superconducting magnets can be used as high-field magnets in magnetic resonance imaging, nuclear magnetic resonance, water purification, magnetic drug delivery, etc. Hunger can be partly avoided if there is sustainability in agriculture. In the future, DC electric energy from solar plants in Africa could be transported worldwide, especially to cold countries, using superconducting cables. Superconducting technology is an efficient way to create sustainability as well as reduce greenhouse gases. This book presents the latest global achievements in the processing and applications of high-Tc superconductors and discusses the usefulness of the SDGs. It summarizes the related advances in materials science and developments with respect to the SDGs. The book also covers large-scale applications of HTSC materials, which will be connected to the SDGs, addressed by several eminent scientists, including Prof. M. Murakami, president, Shibaura Institute of Technology, Japan; Prof. D. Cardwell, pro-vice chancellor, University of Cambridge, UK; and Prof. N. Long, director, Victoria University of Wellington, New Zealand.
