Low-iridium device speeds progress towards green hydrogen
Briefly

Producing 'green' hydrogen through water splitting is vital for mitigating industrial carbon emissions. However, the current technology remains too pricey to outcompete hydrogen sourced from natural gas, which is both cheaper and more polluting. A significant factor contributing to this high cost is the need for electrolysers that utilize catalysts made from rare and expensive materials like iridium. Consequently, advancements in making electrolysis more economical and accessible are necessary to promote the adoption of sustainable hydrogen production.
Producing 'green' hydrogen by splitting water molecules represents a critical step in reducing industrial carbon emissions, but the high cost of electrolysers remains a barrier to adoption.
The reliance on rare elements like iridium for catalysts in electrolysers significantly drives up the production costs of 'green' hydrogen, making it uncompetitive.
