Obinna Chukwuemeka Ugwu is a PhD student at the University of Adelaide. He holds a Bachelor’s degree in Geology from Nnamdi Azikiwe University, Nigeria, and a Master’s degree in Geology for Energy Resources from the University of Perugia, Italy. His research focuses on advancing geological understanding for large-scale hydrogen storage within subsurface salt formations. The project examines macroscopic diapiric inclusions — heterogeneous rock bodies enclosed within salt diapirs — to unravel their stratigraphic and structural complexities. By integrating fieldwork, core analysis, and subsurface geophysical interpretation across South Australia and the Northern Territory, the study aims to identify and de-risk salt cavern sites suitable for safe and efficient hydrogen storage. This work supports Australia’s transition to a low-carbon future by providing geological insights that enhance the safety, efficiency and economic viability of hydrogen storage. The outcomes will inform site selection for underground hydrogen storage, reduce exploration risk and accelerate the development of Australia’s emerging hydrogen economy. Obinna brings experience in sedimentology, stratigraphy and structural geology. Outside academia, he enjoys hiking, watching documentaries, and spending time with friends and family.
