PO144: Economic analysis and risk assessment of offshore high temperature superconducting cable systems
Craig White, PhD student / Economic specialist, WavEC Offshore Renewables
Abstract
This work presents a cost-benefit analysis of high temperature superconducting (HTS) cables, for the purpose of altering the design of high-power electrical transmission systems. HTS systems allow high current transmission of bulk power with minimal losses, increasing system efficiency and reducing levelized cost of energy (LCoE) and the cost of offshore wind farms in general, once technical maturity is achieved. This can aid project financial viability in a challenging time for offshore wind, in a component area often thought of as mature. The economic assessment compares the extra cost, risk, and complexity of HTS systems alongside the benefits that include lower electrical resistance and losses [1], a reduction in electrical conversion equipment at both the generation-side and grid-side, reduced heat and electromagnetic radiation [2], plus the potential for hydrogen transportation within the same transfer system [3]. A range of offshore scenarios and project scales are presented that demonstrate the potential of the technology against the state-of-the-art standard high voltage export cables. HTS incorporate numerous innovative materials that are at the top of a potential cost reduction curve. Learning rates, innovative fabrication methods and potential for material reductions will be presented which have the benefit for lower capital expenditure (CAPEX). A risk assessment then defines the severity and likelihood of hazards associated with demonstrating the technology. These include cooling stations along the cable route, utilisation of cryogenic liquids, superheated cables, and the relative infancy of this new technology. Mitigation strategies to minimise these risks will be examined that include new forms of fault analysis and simulation methods [4]. Overall, the research will assess the potential cost and LCoE reduction that this innovative new form of electrical transmission system can achieve for offshore wind.
