Advancements in Electrolyzer Technology Could Make Green Hydrogen Viable Sooner Than You Think
Historically, the mass production of green hydrogen has not been seen as a viable alternative energy solution for our climate crisis. However, recent advancements in proton exchange membrane (PEM) electrolyzers are changing the narrative. These innovations offer new avenues for long-term viability and present exciting opportunities for manufacturers.
Electrolyzers now last longer, operate more efficiently, and cost less than ever before. With a 90% reduction in uninstalled capital costs over the last two decades, they are becoming a cornerstone technology for achieving “carbon peak and neutrality” goals.
Advancements in Electrolyzer Technology
There have been a few important advancements made in electrolyzer technology. Thinner membranes, for instance, allow for faster proton transportation, which increases hydrogen production by 150% or reduces energy consumption by 10%. These membranes, combined with perforated titanium porous transport layers (PTLs), reduce oxidation, enhance thermal and electrical conduction, and improve mechanical durability. PTLs made from titanium sheets as thin as 0.010″ provide lower oxidation rates and better gas removal pathways, making them an essential innovation in electrolyzer design.
In addition, reduced-iridium coatings on titanium PTLs have eliminated the reliance on expensive platinum group metals. This advancement ensures better electrical conductivity at a lower cost, significantly improving the economic feasibility of PEM electrolyzers. Finally, ongoing research into optimizing cell design has led to electrode structures with up to 50% higher performance, enhancing durability and hydrogen output. Improved cell interactions in the stack further contribute to the efficiency and scalability of electrolyzer technology.
More Green Hydrogen Coming Soon
Electrolyzers may have the most hidden potential of any green energy technology, offering unprecedented efficiency and cost-effectiveness to the energy market. The question now is which manufacturers are prepared to seize this opportunity. As Alex Papandrew, PhD, Senior Program Manager for Clean Energy, and Matt Behrns, Vice President and General Manager of Clean Energy and Marketing at Mott Corporation, highlight, these advancements are the key to a sustainable energy future.
Their expertise underscores the critical role electrolyzers will play in scaling green hydrogen production to meet global energy demands. The green hydrogen market, valued at $185 billion, is expected to grow by over 600% in the next 25 years—driven by these groundbreaking innovations.
