Short answer: PEM electrolyzers handle intermittent solar and wind better than alkaline on raw response speed and minimum load, alkaline paired with batteries closes most of that gap at lower capital cost, and decoupled water electrolysis (DWE) is a newer, structurally different architecture built specifically around unlimited cycling, with commercial-scale proof still pending.

Cutting capital cost for a utility-scale green hydrogen plant comes down to three things working together: stack-level material and design choices, module size, and manufacturing scale, applied against the balance-of-plant equipment that usually costs more than the stack itself. No single lever gets a project to its target CAPEX alone. This guide breaks down where … Read more
Green hydrogen is not going to hit broad cost parity with grey hydrogen by 2030. The latest data points to a narrower outcome: sub-$2/kg production concentrated almost entirely in China, a wider band of $3-plus pricing in favorable regions like Australia, and most of the rest of the world still sitting above $4/kg.
