Can the US Strike Hydrogen Underground?

USGS unveils early hydrogen mapping, stirring scientific and industry curiosity

26 Nov 2025

The US Geological Survey has released a preliminary digital map showing where natural hydrogen might occur underground, giving the first national overview of a resource that remains untested and highly uncertain.

The model, still under development, outlines geological settings that could support hydrogen generation or movement. It does not identify commercial deposits but brings together decades of existing data to highlight areas that merit scientific attention. Researchers caution that the map is an initial tool rather than a guide for extraction and that only drilling can determine whether recoverable volumes exist.

Companies are monitoring the effort but have not shifted strategy. SLB and Chevron have pointed to their work with digital subsurface tools and long-running hydrogen research. However, neither group has linked any plans directly to the USGS mapping. Advisers said the field remains exploratory, noting that “large uncertainty” surrounds potential volumes and that the model should be seen as a scientific starting point rather than a prompt for investment.

The timing reflects growing interest in early-stage clean energy technologies. Investors are surveying options that could offer lower-carbon alternatives, and natural hydrogen has drawn attention because it could provide a fuel formed through natural geological processes without the energy inputs needed for conventional production. Analysts stress, however, that the opportunity is speculative until field evidence emerges.

For the USGS, the mapping marks a first step in understanding an undeveloped resource. The agency aims to refine the model as new data become available. Whether any highlighted zones contain significant, sustainable volumes will depend on upcoming exploration. Until drilling begins, natural hydrogen remains a frontier with potential but without proof.
