LG Chem has developed a PEM electrolysis electrode that significantly reduces iridium consumption in green hydrogen production, lowering a critical cost bottleneck in the electrolyser supply chain. The breakthrough addresses material scarcity and cost constraints that have limited scale-up of water electrolysis for industrial hydrogen.

◆ ◆ The Wire takeaway
If you're selling iridium, rhodium, or platinum-group metals to electrolyser makers, your commodity price just got cheaper and your customers' purchasing power weaker. If you're building electrolysers for industrial hydrogen, LG Chem has just unlocked a material cost reduction that becomes table-stakes within 18 months—and your electrolyser bill of materials needs to match it or you lose the deal.
