Mott Corporation’s electrolyser technology increases green hydrogen production by 150%
January 8, 2025
Mott Corporation, based in Farmington, Connecticut, USA, recently published an article discussing the potential of advancements in proton exchange membrane (PEM) electrolyser technology to make green hydrogen a viable energy solution for addressing the climate crisis.
Electrolysers now last longer, operate more efficiently and come at a lower cost, stated Mott. Over the past two decades, there has been a 90% reduction in uninstalled capital costs, making this technology a cornerstone for achieving carbon-related goals.
Advancements in electrolyser technology
Recent advancements in electrolyser technology have introduced thinner membranes that enable faster proton transportation. This innovation can reportedly increase hydrogen production by 150% or reduce energy consumption by 10%. When paired with Mott’s sintered perforated titanium Porous Transport Layers (PTLs), these membranes reduce oxidation, enhance thermal and electrical conduction, and improve mechanical durability. PTLs made from titanium sheets as thin as 0.254 mm exhibit lower oxidation rates and provide better gas removal pathways, making them a crucial development in electrolyser design.
Reduced-iridium coatings on titanium PTLs have eliminated the dependence on expensive platinum group metals, added Mott. This advancement enhances electrical conductivity at a lower cost, significantly improving the economic feasibility of PEM electrolysers. Additionally, ongoing research into optimising cell design has resulted in electrode structures that deliver up to 50% higher performance, which boosts durability and hydrogen output. Furthermore, improved cell interactions in the stack further contribute to the overall efficiency and scalability of electrolyser technology.
The green hydrogen market, currently valued at $185 billion, is expected to grow by over 600% in the next 25 years. However, this growth will not be possible without the enhanced efficiency and longer lifespans made possible by recent advancements in electrolyser technology.
