Potential geologic hydrogen accumulations in the midcontinent of the United States

A review of potential Nebraska hydrogen resources

There is an area in Southeast Nebraska that shows very distinctive surface patterns, very notable through DEM maps derived from Lidar data. These appear very similar to the structures defined as the Carolina Bays along the Atlantic Coast of the United States. Studies have revealed that the Carolina Bays show elevated readings of hydrogen at the surface, thought to have been generated at depth and found at the surface after upward migration.
These Nebraska features are named the Nebraska Bays. They are evident in loose, fairly unconsolidated loess deposits. Part of the surface geomorphology is controlled by prevailing wind patterns, but the obvious similarity to the Carolina Bays makes one wonder if they are related to deeper hydrogen migrating to the surface. Natural Hydrogen Energy drilled an exploratory hydrogen in the area in 2019. Announcement were made that hydrogen was encountered in the Precambrian basement.

To my knowledge, there has been no published study of hydrogen levels in…
