Salt domes (IMAGE) University of Texas at Austin Caption Large underground salt formations have the potential to aid in the energy transition in myriad ways. Salt deposits can host caverns for hydrogen storage (left) and can help channel heat for geothermal power (right). The geology near salt formations (center left) is often well-suited for permanent carbon storage, which keeps emissions out of the atmosphere by diverting them underground.
