Why a cheaper electrolyser may not mean cheaper hydrogen

An International Energy Agency analysis published on 15 October 2026 revisits a central question for electrolytic hydrogen: does a lower equipment price necessarily produce a cheaper project?

The agency says China accounts for roughly two-thirds of installed capacity worldwide and benefits from a large manufacturing base and strong competition. Yet much of a project's cost relates to its location, engineering, construction and supporting equipment, rather than the electrolyser core alone.

Differences in materials, efficiency and durability can also affect electricity consumption and operating life. An initial price gap may therefore narrow when the full operating cycle is considered.

The useful comparison is between bids assessed on a consistent basis, including efficiency, warranties, construction and electricity. This explanatory report is not a recommendation to buy equipment from a particular country or a guarantee of project returns.
