“…The preconceptual design of the SCEP has been performed according to a functional analysis process, which allows translating the system-level requirements into detailed functional and performance requirements for the subcomponents, see for instance [21]. The process functions, dealing directly with the operation of the SCEP at the target operating parameters, are to guarantee that the device carries the rated current at the rated voltage and to guarantee that the device transfers the rated chemical energy.…”

The design of a single-pole MgB2 superconducting hydrogen-cooled cable for DC current transmission at low voltage (10 kV) is presented here. The cable consists of a former made of MgB2 superconducting wires, a dielectric layer and an annular region that allows for the passage of hydrogen at inlet pressures above the critical one. The cable is contained within a corrugated cryostat, insulated from the external environment. The use of MgB2 as a superconducting material allows for the operation of the cable in the range 15-27 K, which reduces the cooling requirements and increases the efficiency of the system. The hydrogen-cooled annular region, acting as a pipeline for the cryogen transport, allows at the same time the efficient cooling of the cable, while the corrugated cryostat provides additional insulation and structural support, together with a relief volume in the case of an accident. The results of this study, mainly performed with a simplified model, benchmarked against the OPENSC 2 software, show that the cable is able to support DC current transmission at 10 kV, with maximum cable lengths of several tens of km for inner diameters of the cryostat > 120 mm, supporting a H2 mass flow rate > 1 kg/s. Overall, this study demonstrates the feasibility of combining the DC current transmission at lowmedium voltage by MgB2 to the transport of liquid hydrogen, providing at the same time instantaneous storage of chemical power.

The high-temperature superconductor (HTS) plays a crucial role in power grids due to its ability to carry high current densities and withstand strong magnetic fields, making it ideal for applications like superconducting magnetic energy storage (SMES). However, integrating SMES systems with the grid introduces challenges, particularly regarding the generation of AC losses during cyclic operations, which can lead to temperature increases in HTS tape. This article presents a method for calculating AC losses and determining the magnetic field formulation at the critical state of HTS using numerical techniques. The study focuses on analyzing the charging and discharging operations of a grid-integrated SMES system based on silicon-controlled rectifiers. Additionally, the critical current of the HTS tape is determined using the four-probe method to characterize its I-V characteristics.
