Bioderived and Synthetic Hydrogen Storage Materials

Christopher Chukwuati is a distinguished researcher in environmental chemistry based in South Africa. He specializes in designing and developing advanced nanostructured materials for various environmental and energy-related applications, including photocatalysis and water treatment. He has authored and co-authored articles in peer-reviewed journals. Additionally, Dr. Chukwuati is actively engaged in collaborative projects with Hydrox, a hydrogen generation company in South Africa, and continues to explore interdisciplinary solutions to pressing environmental challenges, such as photoelectrochemical water splitting for hydrogen generation.Kingsley Ukoba is a Lecturer and Researcher in the Department of Mechanical Engineering Sciences at the University of Johannesburg, South Africa. He obtained a doctoral degree in Mechanical Engineering from the University of KwaZulu-Natal, Durban, South Africa. He coordinates the smart energy group for JENANO, headed by Prof. Tien-Chien Jen, and oversees a group of doctoral students, master’s, and undergraduate students of the South Africa Research Chair (SARCHI) of Green Hydrogen. Dr. Ukoba has won several individual and group grants, awards, and fellowships, including the one-million South African Rand grant by the SASOL/NRF Collaborative Research Grant for water treatment using Atomic Layer Deposition in 2021. He is also a 2022 Engineering for Change (E4C) fellow, sponsored by the American Society of Mechanical Engineers (ASME), to support an Impact Project around Climate Action. He has authored four books, numerous book chapters, and over 70 journal articles.Tien-Chien Jen is the South Africa Research Chair (SARCHI) of Green Hydrogen and the former head of the Department of Mechanical Engineering Science at the University of Johannesburg, South Africa. He received his Ph.D. in Mechanical and Aerospace Engineering from the University of California, Los Angeles (UCLA), USA, specializing in the thermal aspects of grinding. He has received several competitive grants for his research, including those from the US National Science Foundation, the US Department of Energy, and the EPA. Prof. Jen is the Director of the newly established Atomic Layer Deposition Research Centre at the University of Johannesburg, South Africa, and he is currently leading the drive for the application of Atomic Layer Deposition equipment (the first of its kind in Africa) for various applications (hydrogen, renewable energy, thin films, etc.). He is a fellow of the American Society of Mechanical Engineers (ASME) and a member of the Academy of Science of South Africa (ASSAf). Prof. Jen has authored over 360 peer-reviewed articles, 16 book chapters, and 7 books.
