Through analysis with precision instruments, scientists detected hydrogen and methane inside these inclusions and confirmed that they are linked to specific water-rock chemical reactions. This finding suggests that the plateau may host underground “natural factories” producing hydrogen and warranting further exploration, Liu Tong, first author of the paper and a specially appointed associate researcher at the institute, told the Global Times on Sunday. Researchers also found that hydrogen and methane coexist with alteration minerals typical of serpentinization. This finding provides direct evidence that the serpentinization process - Earth’s most significant natural hydrogen generation mechanism - is either actively occurring or has previously taken place beneath the Qinghai-Xizang Plateau, CCTV reported

I wonder how clean exploration and extraction might be?
