Fig. 7: Relative change of electricity and hydrogen consumer cost depending on the temporal hydrogen regulation.

From: The impact of temporal hydrogen regulation on hydrogen exporters and their domestic energy transition

Fig. 7

Violin plots indicate median (white dot), interquartile range (thick black bar), and 1.5× interquartile range (thin black bar), using kernel density estimation to show the distribution shape of the mitigation-export scenarios, grouped into three stylized transition strategies (1–3) reflecting different sequences of export and mitigation ambition. Domestic electricity consumers (Panel a) profit across all export and mitigation scenarios but most in the group of slow export and quick CO2 mitigation scenarios. Hydrogen exporters (Panel b) experience higher cost with stricter temporal hydrogen regulation. The temporal hydrogen (H2) regulation regulates the welfare distribution between both groups. See Supplementary Fig. 11 for the sensitivity of the export quantities and Supplementary Fig. 3 for scenario grouping.
