Power application of superconductivity technology in China

As a result of the fast rise in power consumption, electrical power generation in China during the past 20 years has increased at an average rate of higher than 8% per year. It is estimated that the power generation capacity in 2020 will be more than 1100 GW. Nevertheless, China is currently experiencing a shortage in the electricity Supply, and there are concerns about insufficient availability of mineral resources in the future. The fast expanding power industry has room therefore for applying new technologies, and high temperature superconductivity is one such promising energy saving and environment friendly new technology. Our analysis suggests that the price of high temperature superconductivity equipment will not be an obstacle for large scale applications. Recently, there has been increased support for R&D for high temperature superconductivity applications in China. Several projects, including production of long lengths of Bi-2223 tapes and high temperature superconducting power cables, have been successfully implemented.
