US Green Hydrogen Market Opportunities and Challenges

Critical Mineral Supply Constraints Create Opportunities for Next-Generation Electrolyzers

The rapid deployment of proton exchange membrane electrolyzers is constrained by the limited availability of iridium and other platinum group metals, creating a significant supply chain challenge for the PEM electrolyzer market. According to the International Energy Agency (IEA, Global Hydrogen Review 2025), conventional PEM electrolyzers typically require 300–400 kg of iridium per GW of installed capacity, while global primary iridium production is only approximately 7.5 metric tonnes annually. The widening supply-demand imbalance is increasing material procurement risks, elevating capital costs, and limiting the large-scale expansion of renewable hydrogen production, thereby posing a critical bottleneck for scaling the green hydrogen value chain.

The growing pressure to reduce dependence on critical minerals is creating significant opportunities for catalyst innovation and alternative electrolyzer technologies. In May 2024, Plug Power Inc. introduced its GenEco PEM electrolyzer platform, designed to improve system efficiency and reduce precious metal intensity for large-scale hydrogen production. Simultaneously, the U.S. hydrogen industry is accelerating the commercialization of low-iridium catalyst technologies, advanced alkaline systems, and anion exchange membrane (AEM) electrolyzers to improve supply chain resilience and lower equipment costs. These technological advancements are strengthening the electrolyzer technology landscape while supporting the long-term competitiveness of the U.S. green hydrogen market.
