Global Installation Production Of Superconducting Cables Decreased From 930 Meter In 2014 To 490 Meter In 2018

Superconducting power cables act as a bridge between electric energy transmission and distribution. In a superconducting power cable, a superconducting conductor that reaches superconductivity of zero electric resistance below a specific low temperature is used, allowing low-loss transmission of large currents.

Superconducting cables with just 20 percent of the thickness of copper cables have an advantage of heightening electric power transmission dimensions a maximum of 10 times (5 times in alternating current, 10 times in direct current) compared to previous cables by using the superconducting phenomenon that electric resistance disappears at -196℃. This means that there is hardly any dissipation of electricity during power transmission. At present, many national research institutions and cable manufacturers are researching and developing this product. The cable market will completely switch to superconducting cables in the future. Many governments are supporting businesses for the commercialization because of the enormous cost of the project.

The global installation production of superconducting cables decreased from 930 meter in 2014 to 490 meter in 2018, at a CAGR of -14.80%. In 2018, the global superconducting cables market is led by China. Europe is the second-largest region-wise market.  The global High Temperature Superconducting Cables market is valued at USD 4.22 million in 2018 and is expected to reach USD 185.07 million by the end of 2025, growing at a CAGR of 71.65% between 2018 and 2025.

As the transmission medium for HVDC applications, superconductor cables can move virtually any amount of power with much greater efficiency than any other transmission technology – and they move it underground, out of site and out of harm’s way. In 2018, the Superconducting Cables consumption (sales) in Grid and Smart Grid was 460, and it will reach 22890 in 2025; while the sales market share in Grid and Smart Grid was 93.9% in 2017 and will be 94.4% in 2025. Within the next 10 years, superconducting power cables could offer significant power transmission solutions for densely populated, high load areas.

Superconductors come in two types, low-temperature (LTS) and high-temperature (HTS). At present, the main type of superconducting cables is the second-generation YBCO Cables, which will also be the mainstream of future development. The first generation HTS will gradually be eliminated. However, YBCO Cables maybe quickly be eliminated by the new materials with better cost and performance in the future. Therefore, the core technology of superconducting cables is superconducting materials.

These unique characteristics of superconducting cables make them an attractive technology, especially in urban areas where underground space and land availability is limited. In these urban areas, the networks are most often reaching their capacity limits, making the case for investigating the feasibility of using HTS cables in electricity distribution networks even stronger. However, the high cost is a key factor limiting the development of this industry.

For many people, it seems that superconductor is an emerging industry, and in fact the product has been continuously researched. Large-scale HTS industrial production still seems to take a long time. The low temperature superconductor industry has been developed for many years and the industry chain is relatively mature. Although the profit margin of superconductor is high, the research funds is also phenomenal, in additional to this, the downstream demand is unstable.
