The systemic approach of Hi-SCALE comprised the definition of strongly interrelated working groups, namely:
- WG1: From Materials to Devices.
- WG2: Improved Modelling and Advanced Computation.
- WG3: Industrial Challenges and Applications.
- WG4: Economy and Life Cycle Assessment.
The primary goal of WG1 was to address knowledge gaps in understanding the properties of HTS under diverse conditions. The group aimed to advance the performance of key conductors, namely REBCO and MgB2, and optimise the design of high-current cables. Additionally, WG1 explored the characterisation of structural and functional materials that could be integrated into HTS devices. Through collaborative efforts, WG1 attempted to improve HTS technology, bridging the gap between material development and practical device implementation.
WG2 focused on developing advanced modelling techniques and computational tools for high-temperature superconducting (HTS) materials and devices. The group tackled the complex challenges intrinsic to HTS systems, such as high nonlinearity, three-dimensional configurations, and the heterogeneous nature of the materials. In addition to developing sophisticated numerical methods, WG2 explored data-driven approaches to enhance the modelling of HTS technologies. A key objective of the group was to create equivalent circuit models and computational tools accessible to industry professionals, facilitating the seamless integration of HTS technologies into existing energy systems.
WG3 concentrated on applying HTS technologies to tackle real-world industrial challenges. The objective of the group was to expand the scientific advancements of WG1 and WG2 into practical, industrial applications. WG3 identified and evaluated use cases where HTS could surpass conventional technologies or introduce new functionalities, particularly in the context of the ongoing Energy Transition. Furthermore, WG3 was involved in testing, ensuring regulatory compliance, and developing prototypes and demonstrators to validate the performance of HTS technologies in industrial environments.
Finally, WG4 focused on the economic and environmental dimensions of high-temperature superconducting (HTS) technologies, specifically examining life cycle assessment (LCA) and economic viability. The group aimed to address the critical need for understanding the broader impacts of HTS applications by evaluating their sustainability and cost-effectiveness within the context of the Energy Transition. WG4’s research included assessing the life cycle of HTS materials and devices, identifying areas for cost reduction, and investigating market adoption barriers.
