In this study, we try estimating hydrogen partitioning between molten silicate and liquid iron under the CMB conditions based on the first principles calculation method combined with thermodynamic integration similar to our previous study (Xiong et al., 2018). As a results, Hydrogen prefers silicate system to iron at CMB condition.
