China green hydrogen costs far lower than Germany, Japan or US, study finds

A new study from the EWI research institute finds that China can produce green hydrogen at a much lower cost than Germany, Japan, or the US. The gap comes from cheaper renewable power, lower equipment costs, and a more established electrolyzer supply chain. That puts China in a strong position for hydrogen-based steel, ammonia, and shipping fuel. The same study says Germany and Japan could largely import renewable hydrogen at a lower price than making it at home. The catch is energy security. Relying on imports for hydrogen could repeat the pattern of natural gas dependency. The full paper matters for anyone tracking where green hydrogen projects get built and which countries will buy versus produce their own supply.

China's cost advantage here is not just about cheap renewables. It is about the whole supply chain, electrolyzers, construction, and permitting. The study is worth a read for anyone tracking where hydrogen projects actually get built.

The import tradeoff is the real story. Germany and Japan can buy cheaper H2 abroad, but then they accept the same energy security risk they already have with natural gas. That tension will drive a lot of policy.

Question on the cost assumptions. Does the study include grid connection costs and curtailment risk for Chinese electrolyzer projects? The Kuqa project gets subsidized power, so comparing it to a German or US project on levelized cost alone can miss the real gap.

This is where subsidy design matters. If Europe and Japan set import targets, they need to decide whether they are buying molecules or building domestic capacity. The study says imports are cheaper, but that ignores the option value of domestic industry.

The study seems to frame energy security as a cost, not just a political goal. That is the right framing. If a country can make H2 at home for a bit more, the premium might be worth it.
