Hydrogen is a key part of the transition to more sustainable processes, not only as a possible transportation fuel for passenger cars, buses, and heavy duty trucks, but across industrial processes and stationary applications. Renewable sources of hydrogen such as water electrolysis are needed in order to address decarbonisation initiatives. While electrolysis has been developed at scale for both alkaline and proton exchange membrane (PEM) technologies, the operating and capital costs still need to be reduced for these markets, especially for the PEM systems. The cost has come down dramatically as systems have scaled up in capacity, but additional savings are feasible based on technology improvements and manufacturing advancements similar to the progress made in PEM fuel cells. These improvements involve both material and process development specific to proton exchange membrane electrolyzers.

氢是向更可持续的过程过渡的关键部分，不仅可以作为乘用车、公共汽车和重型卡车的运输燃料，还可以用于工业过程和固定应用。需要可再生的氢源，例如水电解，以解决脱碳计划。虽然碱性和质子交换膜 (PEM) 技术都已大规模开发电解，但这些市场的运营和资本成本仍需降低，尤其是 PEM 系统。随着系统容量的扩大，成本已大幅下降，但基于与 PEM 燃料电池取得的进展类似的技术改进和制造进步，额外的节省是可行的。
