If you decide to build a house, you know that you need raw materials. And you also know that those raw materials will probably be readily available. If you’re going to build a completely new sustainable energy system, it’s clear that you need rapidly growing supplies of materials. However, the possible supply risks facing some critical raw materials have barely been taken into account in drawing up energy plans for the future.
In part one of a two-part publication, ‘Towards a greener future’, we focus on the production of green hydrogen. To achieve the European hydrogen plans by 2050, we need iridium. Lots of iridium. And we anticipate a shortage of this metal, as hydrogen production is not the only application that requires iridium. It’s an essential material in the various energy transition routes. As a consequence, the whole energy transition is at risk of suffering delays or even of grinding to a complete halt.
However, we note that the critical raw materials required for producing green hydrogen continues to be overlooked. Based on our first paper, we conclude that it’s time to put this topic on the agenda – including the political agenda – and to take action.
