Les ventes de voitures hybrides ont explosé en Europe cette année. Malheureusement, les moteurs à combustion interne de ces voitures ont tendance à faire plus de départs à froid, parce que la voiture passe du mode électrique au mode fossile. Ces départs à froid, sont fortement émetteurs d'oxydes d'azote, un puissant gaz à effet de serre. Pour compenser, ces voitures sont munies de catalyseurs plus puissants, comportant plus de platine et de rhodium. La demande en rhodium a explosé et comme la production est contrainte, le rhodium est récemment devenu le métal le plus cher de l'histoire, à 14,750 dollars l'once (28 grammes). Le texte qui suit est extrait d'un texte plus long, portant sur un autre sujet, ---- I view hybrids as a wolf in sheep's clothing since the most stressful load on emissions of air pollution and greenhouse gases occurs during a cold start and hybrids have a lot of those. This means that autocatalysts for them need higher loadings of platinum-group metals (PGMs) to counter this effect. Compared to a conventional vehicle, the PGM loadings in hybrids seem to be around 10% higher.
I see an opportunity here as rhodium is the only viable option to limit nitrogen oxide ((NOx)) pollution in passenger cars and the fundamentals for this metal are already significantly stressed. Due to tightness in the spot market, it recently became the highest priced metal in history at $14,750 per ounce. According to Heraeus Precious Metals, the deficit in the rhodium market is set to widen to 55,000 oz in 2020 from 20,000 oz in 2019. I think this market is unlikely to become balanced anytime soon as rhodium is a by-product of platinum and palladium mining, which means it’s not sensitive to price changes..
Le métal précieux est en hausse de plus de 30% depuis le 1er janvier et s’échange à plus de 8000$ l’once. Malgré ses bonnes performances, l’or s’échange cinq fois moins cher.
