Resilient & Optimised Grids Closed-Loop Aluminium for European Energy Security

Electricity grids are at the core of the energy transition, requiring increasing modernisation and expansion to enable renewable energy integration, electrification, and digitalisation. However, these advancements come with strategic challenges, particularly in the context of climate change, resource scarcity, and supply chain disruptions, as well as rising geoeconomic and geopolitical constraints affecting global value chains.

Such global geopolitical tensions have exposed vulnerabilities in the supply of critical materials and components such as copper, aluminium, transformers and cables, which are essential for maintaining and developing the electricity grid infrastructure. Disruptions have led to delays, increased costs, and uncertainty in project execution, posing significant roadblocks to the timely development of resilient and sustainable renewable electricity systems.

Closed-Loop Aluminium for European Energy Security

Faced with the rising global demand for aluminium and considering the importance of sustainability aspects, RTE has recognised the urgent need to reduce reliance on raw materials.

In collaboration with local partners, including MTB Recycling, Trimet, and Nexans, RTE’s project successfully produced 40 kilometres of high-voltage aluminium alloy conductors using recycled aluminium. This practice demonstrates that recycled materials can match the mechanical strength and electrical conductivity of the TSO technical specification, while cutting CO₂ emissions. Such innovation is essential for reducing Europe’s dependence on imported resources, showcasing how circularity can reduce environmental impacts and vulnerability to supply chain risks.

The outcomes of the project align with the EU’s strategic priorities, paving the way to carbon neutrality by 2050, achieving strategic autonomy and increasing competitiveness. It can inspire replication, fostering a future where resource efficiency and innovation drive grid resilience. Register now to learn more and contribute to the discussion!
