The hidden engineering challenges of scaling electrolysers
Episode 5 of the Chade Hydrogen podcast: the engineering problems that only appear when electrolysers move from prototypes to volume production — and what separates the projects that scale from the ones that stall.

- A single cell that works on the bench is a lab result, not a product.
- On the way to the megawatt, everything changes: cell chemistry, stack distribution and sealing, heat, gas and mechanics at scale, balance of plant and controls, duty cycles and durability.
- Each rung must prove out before the next is funded — skip one and you meet its problem later, at ten times the cost.
- A megawatt is not a big cell — it is a different machine, governed by heat, water, mechanics, materials and manufacturing.
- Respect that gap early and it is an engineering programme; ignore it and it becomes a post-mortem.
