Area of Science:

  • Materials Science
  • Supply Chain Management
  • European Technological Policy

Background:

  • Global supply chain disruptions highlight the urgent need for raw materials for next-generation technologies.
  • Current frameworks for 'critical' and 'strategic' materials do not encompass advanced materials essential for innovation.
  • Advanced materials, including nanomaterials, are key drivers of modern technological advancements.

Purpose of the Study:

  • To introduce a novel self-reliance index quantifying European autonomy for elements, compounds, and devices.
  • To assess the performance of advanced materials in relation to their supply chain dependencies.
  • To propose a new definition for 'strategic advanced materials' based on local availability and performance.

Main Methods:

  • Development of a self-reliance index incorporating import dependence, recycling rates, and supplier concentration.
  • Analysis of state-of-the-art performance for advanced materials across various applications (conductors, semiconductors, dielectrics, battery electrodes, photovoltaic layers).
  • Correlation of the self-reliance index with material performance to identify European-sourced substitutes.

Main Results:

  • High-performance advanced materials heavily reliant on imported elements often have comparable European-sourced substitutes.
  • The study quantifies European autonomy for critical elements, compounds, and devices.
  • A clear link was established between material performance and the availability of local inputs.

Conclusions:

  • Defining 'strategic advanced materials' as those offering high performance using locally available inputs is proposed.
  • The developed framework serves as a tool for researchers and policymakers to bolster supply chain resilience.
  • Strengthening European technological sovereignty through strategic material sourcing is achievable.
