Natural hydrogen generation potential of the serpentinized ultramafic rocks of the Biga Peninsula (NW Anatolia-Türkiye): petrographic controls, reaction pathways, and initial quantitative estimates İsmail Onur Tunç Scientific Reports volume 16 , Article number: 26941 ( 2026 ) Natural hydrogen (H 2 ), increasingly referred to as geologic or white hydrogen, has lately attracted considerable interest as a clean and potentially renewable energy resource produced through various subsurface geochemical processes. This study presents the first quantitative evaluation of the natural H 2 generation potential of the Biga Peninsula (NW Anatolia, Türkiye) and identifies it as a prospective target warranting systematic exploration-phase investigation, focusing on the Denizgören and Tozlu metaophiolitic units. Two independent estimation methods are applied and reconciled: (1) an empirical yield approach calibrated from laboratory serpentinization experiments (Method 1), an...
