📄 Abstract（原文）
This paper presents the state of the art, emerging trends, and associated challenges concerning the reduction of rare earth materials in offshore wind energy and green hydrogen production. In the context of offshore wind, there is increasing interest in permanent magnet synchronous generators for large-scale turbines. However, a significant challenge posed by permanent magnets is their dependence on rare earth elements. Similarly, green hydrogen and its electrolysers also require rare earth elements and other critical raw materials, the extent of which varies according to the technology employed. The objective of this study is to examine the current utilisation of rare earth materials in offshore wind turbines and green hydrogen production. It explores the state of the art, development trends, and proposes a pathway forward. The research approach involved a comprehensive analysis of academic literature, expert opinions, and industrial reports from both contemporary and historical perspectives. A critical evaluation of the advantages and disadvantages of employing rare earth-based permanent magnets in the offshore wind industry is provided. Furthermore, insights from ongoing research projects aimed at reducing rare earth element usage in offshore wind applications are discussed. Alternative solutions, such as medium-speed drivetrains and magnets with reduced rare earth content, are assessed. Another strategy to mitigate dependency on rare earth elements in wind turbine generators involves replacing rare earth-based magnets with alternative materials. Innovations in generator design, technological advancements, and the identification of viable substitute materials are essential for scalability and the continued development of offshore wind energy. Additionally, the proposed pathway underscores the importance of strategic research investments and diversification of material supply chains to support future progress. Finally, it emphasises the need to prioritise research on the reduction and substitution of rare earth elements.
