KAUST's Center of Excellence for Renewable Energy and Storage Technologies (CREST) hosted a seminar on rechargeable hydrogen gas batteries. Professor Wei Chen from the University of Science and Technology of China (USTC) presented the seminar. The talk covered aqueous nickel-hydrogen gas, proton-hydrogen gas, halogen-hydrogen gas, and nonaqueous lithium-hydrogen gas batteries, along with applications like self-charging batteries. Why it matters: Hydrogen gas batteries represent a promising avenue for large-scale energy storage, particularly for integrating renewable energy sources into electric grids.
KAUST researchers investigated repurposing depleted oil reservoirs for underground hydrogen storage using liquid organic hydrogen carriers (LOHC). The study, led by Professor Hussein Hoteit, explores the technical feasibility and economic viability of this approach. It suggests that depleted oil reservoirs could serve as long-duration hydrogen storage sites, reducing the need for new infrastructure. Why it matters: The research supports Saudi Arabia's energy transition by utilizing existing hydrocarbon reservoirs for hydrogen storage, aligning with efforts to develop sustainable energy systems.
A KAUST-led multidisciplinary research team is studying the feasibility of storing CO2 in subsurface rock structures in Saudi Arabia, specifically in Harrat near Madinah. The project, conducted under the auspices of the Saudi Ministry of Economy and Planning, involves researchers from KAUST, King Abdulaziz University, and MEP. The team is investigating carbon capture and storage as a means to address climate change and meet Saudi Vision 2030 goals. Why it matters: This research could provide a pathway for Saudi Arabia to reduce CO2 emissions and contribute to global climate change mitigation efforts, aligning with the Kingdom's commitment to the Paris Climate Agreement.
