Electricity Price Dominates
Across major public analyses of PEM electrolysis economics, the price of electricity is a major driver of hydrogen production cost.
What This Means in Practice
- Electrolysers convert electrical energy into hydrogen; “cheap hydrogen” generally requires cheap electricity and sensible system sizing.
- Real performance depends on operating point, stack condition, water quality, and BOP efficiency.
- For project planning, credible public studies can be used to frame expectations.
