How to Produce Green Hydrogen from Olivine and Seawater? By Ultrasound.
Article in ChemSusChem, 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
Green hydrogen is a pillar for achieving global decarbonization and the reduction of greenhouse gas emissions. Here, a new, nature-inspired process for green hydrogen production using virtually unlimited natural resources is reported. Olivine, the most abundant mineral in the Earth's upper mantle, is key to this process. It is found that 20 kHz ultrasound accelerates hydrogen production from olivine suspensions in seawater under near-ambient conditions by almost 3000 times compared to the hydrothermal process. Strong mechanical stirring does not lead to hydrogen evolution in the temperature range of 40-90 °C. The striking effect of ultrasound is attributed to acoustic cavitation, which provides depassivation of the olivine surface, fragmentation of olivine particles, and local transient heating caused by collapsing bubbles. In principle, ultrasonic activation of the olivine/seawater system enables on-demand hydrogen production.
