“…Under such circumstances, a lower heat load is imposed to the cooling system and this increases the efficiency and reliability of the cooling system while the temperature becomes more stable. Another potential application of DC HTS cable is in data centres that play a critical role toward the full digitalization of power systems [210]. These centres require DC power to run their internal devices such as routers, switches, computers, etc.…”

Along with advancements in superconducting technology, especially in high temperature superconductors (HTS), the use of these materials in power system applications is gaining outstanding attention. Due to the lower weight, higher current carrying capability, and the lower loss of HTS cables compared to conventional counterparts, they are among the most focused applications of superconductors in power systems. In near future, these cables will be installed as key elements not only in power systems but also in cryo-electrified transportation units, which take advantage of both cryogenics and superconducting technology simultaneously, e.g. hydrogen-powered aircraft. Given the sensitivity of the reliable and continuous performance of HTS cables, any failures, caused by faults, could be catastrophic, if they are not designed appropriately. Thus, fault analysis of superconducting cables is crucial for ensuring their safety, reliability, and stability, and also for characterising the behaviour of HTS cables under fault currents at the design stage. Many investigations were conducted on the fault characterisation and analysis of HTS cables in the last few years. This paper aims to provide a topical review on all of these conducted studies, It will discuss the current challenges of HTS cables and after that current developments of fault behaviour of HTS cables would be presented, and then we will discuss the future trends and future challenges of superconducting cables regarding their fault performance.

“…In addition to the significant efficiency improvement achieved by the uses of superconducting inductor and cryogenic power electronic switches, this emerging cryogenic power conversion technology also has the several accessary advantages as follows [21]: (1) Elimination of large-volume and heavy-weight drawbacks in conventional air or water cooled devices; (2) elimination of potential overheating risks in MOSFETs; (3) permission of high current and power ratings. Therefore, based on experimental and theoretical analyses on the high-efficiency superconducting inductor in this paper, and the loss characteristics of cryogenic power electronic switches in the literatures [33][34][35][36][37][38], there would be further balance and optimization of the operating parameters of superconductor elements and semiconductor devices in various cryogenic power conversion systems, with proper design guidelines [39][40][41].…”

To break through the bottlenecks of the loss and size of conventional conductors and magnetic materials, replacing copper inductors by zero‐resistance superconducting inductors can be a promising solution. The experimental, theoretical and numerical investigations into the loss characteristics of an air‐core superconducting inductor have been carried out. All these results show that the loss from a superconducting inductor in the boost chopper circuit was reduced remarkably up to 373 times smaller than the loss from the magnetic‐core copper inductor having the same conditions. Moreover, the actual volume and weight of the superconducting inductor are only 5.61% and 10.97% of those of the copper inductor having the same inductance and current capacities. Advanced numerical models have been built to verify the experiments that their results of superconducting losses as well as the current and frequency dependencies are well matched. A compact, low‐loss and low‐cost cryostat has been designed to accommodate the superconducting inductor, which can further improve the practicability for superconducting inductor to be equipped into various power electronic applications. The superconducting inductor can lead power electronic devices towards ultra‐high‐efficiency power conversion.

“…Data centres have become an integral part of modern society enabling fast communications for e-mail and social media, the storage of public and networked data remotely, and robust networking to have almost instant access to any of this data from an internet/intranet connection [1]. A data centre can vary in size depending on the amount of data that it has to store or transfer, from micro data centres (1-100 kW) that can be portable and used for environmental or construction projects [2], to hyper-scale data centres (100+ MW) that could maintain telecommunications of entire countries [3]. The ever-increasing use of server-dependant technologies like smartphones [4], online gaming [5] and media streaming [6] is increasing the demand for data centres.…”

Data centres, though a necessary part of modern society, are being stigmatised for consuming vast amounts of electricity for their operational and cooling needs. Due to Ireland’s reliance on fossil fuels to meet the increased energy demand of data centres, the data centres are contributing significantly to Ireland’s total carbon emissions. As much of this energy is expelled from data centres as waste heat energy, the potential for recycling some of this wasted heat energy was explored using environmentally friendly systems from recent publications. The recovered waste heat energy was applied in a vertical farming system, and the benefits of this waste heat to the vertical farm were analysed and quantified in two scenarios. Using conservative estimates, it was predicted that each vertical farm could be between 5-23% the size of the data centre and produce enough food to feed between 14-61 adults their daily calorie needs, and between 13-58 people their daily fresh produce requirements, depending on the scenario applied. For a more accurate prediction, each vertical farm would have to be assessed on a case-by-case basis. However, there was not enough data available on Irish data centres to perform these calculations.
