Electrolytic hydrogen production; how green must green be?
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Electrolytic hydrogen from renewable sources is central to many nations' net-zero emission strategies, serving as a low-carbon alternative for traditional uses and enabling decarbonization across multiple sectors. Current stringent policies in the EU and US are set to soon require hourly time matching of renewable electricity generation used by electrolyzers, aimed at ensuring that hydrogen production does not cause significant direct or indirect emissions. While such requirements enhance the "green credentials" of hydrogen, they also increase its production costs. A modest relaxation of these requirements offers a practicable route for scaling up low-carbon hydrogen production, optimizing both costs and emission reductions. Moreover, in jurisdictions with credible and near-to-medium-term decarbonization targets, immediate production of electrolytic hydrogen utilizing grid electricity would have a lifetime carbon intensity comparable to or even below blue hydrogen and very significantly less than that of diesel, emphasizing the need to prioritize rapid grid decarbonization of the broader grid.
