“…The abundance and the versatility of aluminium in various applications have made it one of the top solutions for lightweight metal strategy in various industries such as automotive (Liu and Müller, 2012). In the cable industry, substitute copper for aluminium can considerably reduce the linear weight without degrading too much the electrical properties (Bruzek et al, 2015). To obtain optimal electrical conductivity, aluminium use for cables has purity above 99.…”

Life cycle impact of European generic primary and secondary aluminium are well defined. However specific endof-Life scenario for aluminium products are not available in the literature. In this study, the environmental assessment of cable recycling pathway is examined using the Life Cycle Assessment (LCA) methodology. The data comes from a recycling plant (MTB Recycling) in France. MTB Recycling process relies only on mechanical separation and optical sorting steps on shredder cables to obtain a high purity aluminium (above 99.6%). The life cycle assessment results confirm the huge environmental benefits for aluminium recycled in comparison with primary aluminium. In addition, our study demonstrates the gains of product centric recycling pathways for cables. The mechanical separation is a relevant alternative to metal smelting recycling. This work was done firstly to document specific environmental impact of the MTB Recycling processes in comparison with traditional aluminium recycling smelting. Secondly, to provide an environmental overview of the process steps in order to reduce the environmental impact of this recycling pathway. The identified environmental hotspots from the LCA for the MTB recycling pathway provide help for designers to carry on reducing the environmental impact.

“…Superconducting cables Superconducting dc cables have been intensively developed over the past decades, and the transmission of bulky power is possible with the existing technologies [17]. For long distance applications, the environmental benefit of the superconducting cable system is evident with compact installation and only 10% of ohmic losses of a conventional cable regardless of the voltage level [17]. Recently, a 320kV/10kA superconducting cable has been demonstrated in the EU Best Paths project [18]; and the technology is now close to commercial deployment.…”

“…They also provide increased power transmission capacity that could match OH options in efficiency. However, the technology is still very expensive for long-distance implementation with limited availability and requires extensive additional research and validation [152,153]. 2,000 MW/±320 kV** (INELFE) [118] Longest Distance 580 km (NorNed) [127] 400 km (NordBalt) [147] * Special types of XLPE cables are rarely used in LCC projects (e.g.…”

HVDC systems are playing an increasingly significant role in energy transmission due to their technical and economic superiority over HVAC systems for long distance transmission. HVDC is preferable beyond 300-800 km for overhead point-to-point transmission projects and for the cable based interconnection or the grid integration of remote offshore wind farms beyond 50-100 km. Several HVDC review papers exist in literature but often focus on specific geographic locations or system components. In contrast, this paper presents a detailed, up-to-date, analysis and assessment of HVDC transmission systems on a global scale, targeting expert and general audience alike. The paper covers the following aspects: technical and economic comparison of HVAC and HVDC systems; investigation of international HVDC market size, conditions, geographic sparsity of the technology adoption, as well as the main suppliers landscape; and high-level comparisons and analysis of HVDC system components such as Voltage Source Converters (VSCs) and Line Commutated Converters (LCCs), etc. The presented analysis are supported by practical case studies from existing projects in an effort to reveal the complex technical and economic considerations, factors and rationale involved in the evaluation and selection of transmission system technology for a given project. The contemporary operational challenges such as the ownership of Multi-Terminal DC (MTDC) networks are also discussed. Subsequently, the required development factors, both technically and regulatory, for proper MTDC networks operation are highlighted, including a future outlook of different HVDC system components. Collectively, the role of HVDC transmission in achieving national renewable energy targets in light of the Paris agreement commitments is highlighted with relevant examples of potential HVDC corridors.
