MARKET RESTRAINTS

The shortage of iridium is majorly hampering the growth of the global PEM electrolyzer market.

The iridium plays a crucial role in the PEM electrolysis as an anode where the increased demand for clean hydrogen will impact due to its reliance on precious catalyst material like iridium. The limited availability of iridium worldwide will act as a significant hurdle to market growth. Another factor is the high costs associated with the proton exchange electrolyzers, which involve complex engineering and specialized materials, hindering the market growth opportunities. The high equipment cost will restrict access to small-scale industries, limiting market expansion. The increased initial costs may prevent investors and companies from entering the market, which impedes market growth. Other drawbacks, such as limited durability and high thickness of the proton exchange membrane, causing resistance to proton flow, are estimated to restrain the adoption, leading to restricted market growth. The stringent regulations regarding the approval of innovations in the product and the safety and efficacy of the electrolyzer will act as challenges for manufacturers in expanding the market.
