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.
Researchers at KAUST, USTC, and SUSTech have developed a method for carbon capture and storage using guanidinium sulfate salt to create clathrate structures that trap CO2 molecules. This salt-based structure mimics methane hydrate activity and captures CO2 through physisorption, without water or nitrogen interference. The method allows CO2 to be carried as a solid powder at ambient temperature and pressure, offering a less energy-intensive alternative to traditional methods. Why it matters: This innovation introduces a new, energy-efficient way to store and transport CO2 as a solid, potentially revolutionizing carbon capture and storage technologies in the region and beyond.
KAUST and GE have partnered to study the feasibility of using crude oils like Arabian Super Light (ASL) to power heavy-duty gas turbines. The collaboration aims to develop turbines capable of burning crude oil directly from the ground to meet Saudi Arabia's energy security needs. The research involves building a rig at KAUST's High Pressure Combustion Laboratory (HPCL) to conduct corrosion tests on turbine materials by burning ASL/AXL crude continuously for 2,000 hours. Why it matters: This partnership could reduce reliance on natural gas and offer an economically viable alternative fuel source, bolstering energy security in Saudi Arabia and potentially influencing turbine technology worldwide.
KAUST hosted the Frontiers in Energy Storage 2026 conference, emphasizing energy storage technologies for renewable energy. The conference highlighted electrochemical and chemical systems, including advanced batteries and hydrogen, as complementary layers for long-duration and industrial resilience. KAUST is developing energy-storage solutions relevant for the Kingdom and valuable to global partners, aiming to engineer solutions to withstand extreme environmental temperatures. Why it matters: This positions Saudi Arabia as a potential global exporter of resilient energy hardware, aligning with Saudi Vision 2030 goals in renewable energy.
