Okres sprawozdawczy: 2020-01-01 do 2021-12-31
Superconductivity presents a huge interest worldwide for its opportunities in cleantech energy. However, major challenges currently limit the practical use of HTS conductors: (i) the high cost / performance ratio imposed by the fabrication methods of kilometer-lengths epitaxial YBCO films, limits CC manufacturing throughput through low growth rates; (ii) the low throughput in the production of CCs leads to a severe limitation in generating drastic cost reductions for CCs, required for wide market implementation. Due to overall cost, it is uneconomical to unlock the potential of large-scale applications such as wind turbines, generators, rotating machines for electrical aircrafts, Superconducting Magnetic Energy Storage or advanced HTS MRI / NMR machines, where the HTS material cost can reach 1/3 of the full device. Cost/performance is the main barrier, the bottleneck of superconductor CC industry, which currently costs 200 €/kAm (1 €/kA-m meaning 1 € for a 1m tape able to carry 1 kA).
As a solution, we combine low cost (CSD), high throughput (TLA ultrafast growth) and high performance (nanocomposites), by integrating additive manufacturing processes and digital printing, to deliver a commercially relevant and industry scalable manufacturing process for HTS CCs.
Within the ERC Proof of Concept, our aim was to develop a solid strategy for decreasing time to market of our CSD-TLAG technology by working on two key points:
▪ Technology: to validate it with commercial reel-to-reel substrates (available from existing collaborators)
▪ Commercial: to create a blueprint for the transition from a CSD process reel-to-reel pilot plant implementation to a TLAG-CSD one (collaborating with existing partners).
Homogeneous epitaxial TLAG-CSD growth of YBCO layers on 5 cm tape have been obtained with good performances (Jc(77K) = 1MA/cm2) and fast growth rates (beyond 1000 nm/s) with simplified processing set up scalable to reel-to-reel coated conductor production.
2G HTS superconductivity sector is the target market for TLAG process. A competitive and gap analysis indicates that TLAG could gain market share leveraging its synergies with existing production methods. Strategies for future development were identified for protecting the technology.
