Electrolyzer capital cost is only part of what determines the price of hydrogen from a utility-scale plant, and it's rarely the part people think it is. Balance-of-plant equipment, cooling, compression, gas purification, power electronics, and water treatment, frequently costs more than the stack itself. This video breaks down where the money actually goes and what you can do about it.
You'll see why SOEC stacks run around 30 percent of system cost and AEM stacks closer to 19 percent, leaving the majority of cost outside the stack in both cases. You'll get the three levers that move CAPEX at utility scale: stack-level material choices like removing platinum-group metals and membranes, module size, which spreads balance-of-plant cost across more output, and manufacturing scale, where automation lowers the cost of building each unit.
You'll also see where these levers hit limits, since site-specific factors like permitting, water access, and interconnection add costs that generic benchmarks don't capture, and how falling Chinese electrolyzer prices have compressed the cost advantage other technologies used to claim.
The video walks through how H2Pro's Decoupled Water Electrolysis (DWE) applies the stack-materials lever specifically: no membrane, no platinum-group metal catalysts, nickel-based electrodes instead, in an ambient-temperature, plastic-based design, a company claim not yet independently benchmarked at commercial scale.
If you're planning or evaluating a utility-scale hydrogen project, this gives you the framework to evaluate vendor cost claims beyond the headline per-kilowatt number.
