The article highlights the essential yet often overlooked roles of iridium and rare-earth elements (REEs) in driving the transition to a cleaner and greener energy future. Iridium, a key component in hydrogen fuel cells and electrolysers, is crucial for producing green hydrogen efficiently. However, its extreme scarcity poses challenges in meeting the growing demand for hydrogen production. Researchers are exploring ways to reduce iridium dependency through innovative catalysts and alternative materials. Similarly, REEs, despite their relative abundance, face economic viability issues due to rare deposits. These elements are vital in manufacturing high-performance magnets crucial for electric vehicles and wind turbines. The demand for REEs is expected to surge as the global economy shifts towards clean energy, necessitating increased production outside China. Investing in a diverse portfolio of energy transition commodities, including iridium and REEs, is crucial for supporting the development of essential technologies. The article also introduces the WisdomTree Energy Transition Metals and Rare Earths Miners UCITS ETF, providing investors with an opportunity to participate in this growing sector.
