Key Drivers:

The Market is Steadily Growing as a Result of Rising Global Focus on Decarbonization

As nations and businesses work to cut greenhouse gas emissions and switch to cleaner energy sources, the global emphasis on decarbonization is a significant driver of the PEM electrolyzer market expansion. Decarbonizing hard-to-abate industries including heavy industry, transportation, and power generation is thought to be made possible by green hydrogen, which is created using PEM electrolyzer that are fueled by renewable energy. Particularly in areas comprised of the EU, US, and Asia-Pacific, this has resulted in more government backing through subsidies, regulatory requirements, and strategic hydrogen roadmaps. PEM electrolyzers are at the forefront of the clean energy revolution as a result of the growing demand for effective and scalable hydrogen generation methods.

• For instance, according to the data published by MDPI, A review of global CO2 emissions over the last century shows that emissions from 80 economies contributed to 95% of global emissions. Among them, 55 economies were decarbonizers, where CO2 emissions had either plateaued or were declining, while 25 economies were polluters, where CO2 emissions were still increasing.

Restraints:

Supply Chain Constraints may Impedes the Market from Development

The primary cause of supply chain restrictions in the PEM electrolyzer market is the high cost and restricted availability of vital raw materials, such as iridium and platinum, which are necessary for the production of catalysts. Since these rare metals come from a small number of nations, the supply chain is susceptible to trade restrictions, price volatility, and geopolitical threats. Furthermore, the current manufacturing capacities for essential electrolyzer components are being strained by the quick worldwide scale-up of hydrogen generation.

• Counterbalance Statements: Investing in the creation of alternative, earth-abundant catalyst materials, boosting precious metal recycling, diversifying supply sources, and enhancing local manufacturing skills are some ways to overcome these issues. Building a more robust and sustainable supply chain also requires cooperation between governments, academic institutions, and commercial businesses.
