Research Area 1: Geologic Hydrogen
Geologic Hydrogen (H2)
Geologic H2 is an emerging primary energy source and has the potential to be a gamer changer for low-cost energy supplies and energy security. Geologic H2 includes natural H2, which occurs naturally in the Earth’s crust, and stimulated H2, which is produced by stimulating the generation in the crust.
- Identify source-rock locations and volumes
- Identify reservoir locations and volumes
- Delineate serpentinization degree in source rocks
- Monitor simulated H2 systems
- Develop subsurface exploration tools for hydrogen system
- Integrate geophysics for imaging H2 geology
- Optimize geophysical survey for H2 detection
H2 exploration using both surface and subsurface geophysical data
Overlaying with the digital elevation model (DEM) showing the fairy circle clearly, we display our inversion result from the electrical data. The penetration depth of this electrical survey is around 250m. The high conductivity subsurface is relatively wet material, and can play the role of H2 barrier. These protruding features have low conductivity, showing drier subsurface allowing potential H2 seeping to the surface. These features are consistent with the results in the literature that the High H2 concentrations are usually near the rim of fair circle from soil gas sampling results.
