A standard ingredient — salt — may have an enormous function to play within the vitality transition to decrease carbon vitality sources. That is in accordance with a brand new examine led by researchers at The College of Texas at Austin’s Bureau of Financial Geology.
The examine describes how massive underground salt deposits may function hydrogen holding tanks, conduct warmth to geothermal vegetation, and affect CO2 storage. It additionally highlights how industries with current salt experience, similar to resolution mining, salt mining, and oil and gasoline exploration, may assist.
“We see potential in making use of data and information gained from many a long time of analysis, hydrocarbon exploration, and mining in salt basins to vitality transition applied sciences,” mentioned lead writer Oliver Duffy, a analysis scientist on the bureau. “Finally, a deeper understanding of how salt behaves will assist us optimize design, cut back danger, and enhance the effectivity of a variety of vitality transition applied sciences.”
The examine was revealed within the journal Tektonika.
Salt has an influential function in shaping Earth’s subsurface layers. It’s simply squeezed by geologic forces into complicated and large deposits, with some subsurface salt constructions taller than Mount Everest. These constructions and their surrounding geology provide a variety of alternatives for vitality growth and emissions administration, mentioned examine co-author Lorena Moscardelli, the director of the bureau’s State of Texas Superior Useful resource Restoration (STARR) program.
“The co-location of floor infrastructure, renewable vitality potential, favorable subsurface circumstances and proximity to markets is vital to plan for subsurface hydrogen storage,” she mentioned. “STARR is at present engaged with rising vitality alternatives in West Texas that contain hydrogen and carbon seize, utilization and storage potential for the area.”
Salt domes are confirmed containers for hydrogen utilized by oil refineries and the petrochemical business. In response to the paper, these salt formations is also put to make use of as holding pens for hydrogen certain for vitality manufacturing. What’s extra, the porous rock surrounding them could possibly be used as a everlasting storage spot for CO2 emissions. The examine describes the potential advantages of co-locating hydrogen manufacturing from pure gasoline known as “blue hydrogen” and CO2 storage. Whereas the hydrogen is distributed to salt caverns, the CO2 emissions generated by manufacturing could possibly be saved from the ambiance by diverting them to the encompassing rock for everlasting storage.
With its quite a few salt domes surrounded by porous sedimentary rock, the Texas Gulf Coast is especially nicely fitted to such a mixed manufacturing and storage, in accordance with the researchers.
The examine additionally touches on how salt can support within the adoption of next-generation geothermal know-how. Though the business remains to be in its early phases, the researchers present the way it could make use of salt’s capability to simply conduct warmth from hotter underlying rocks to supply geothermal energy.
Bureau Director Scott Tinker mentioned that as a result of salt has a job to play in growing new vitality sources, it is necessary that a number of avenues are completely explored. He mentioned that researchers on the bureau are enjoying a crucial function in doing simply that.
“Bureau researchers have been learning subsurface salt formations for a lot of a long time. For his or her function in hydrocarbon exploration, as a part of the Strategic Petroleum Reserve, for storage of pure gasoline, and now for his or her potential to retailer hydrogen,” he mentioned. “That is the exceptional factor about nice analysis. It simply retains evolving, enhancing and discovering new purposes.”
Extra co-authors embody present and former bureau researchers Michael Hudec, Frank Peel, Gillian Apps, Alex Bump, Tim Dooley, Naiara Fernandez, Shuvajit Bhattacharya, Ken Wisian and Mark Shuster.
STARR funded the analysis. Their work enhances analysis of different bureau analysis teams centered on the vitality transition, similar to GeoH2, AGL and HotRock.
The bureau is a analysis unit of the UT Jackson Faculty of Geosciences.
