KAUST researchers found that sulfate ions reduce free water in aqueous batteries, mitigating parasitic reactions that degrade the anode and shorten battery life. Adding zinc sulfate increased battery lifespan by more than ten times. Sulfate salts stabilize the bonds of free water, acting as a "water glue" to reduce parasitic reactions. Why it matters: This finding provides a cheap and scalable approach to improve the viability of aqueous batteries for sustainable energy storage, particularly for integrating renewable energy sources.
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 researchers have discovered that the bacterium Enterobacter sp. SA187, found in desert plants, enhances plant salt tolerance by triggering sulfur metabolism. Salt stress prompts the bacteria to release sulfur metabolites, which then generate the antioxidant glutathione in the plant, protecting it from salt-induced damage. A KAUST startup aims to commercialize SA187 as a probiotic treatment for seeds and crops. Why it matters: This research offers a biotechnological approach to enable saline agriculture, which is crucial for water-scarce regions like Saudi Arabia that rely on energy-intensive desalination.
Five KAUST professors (Mohamed Eddaoudi, Omar F. Mohammed, Nivine Khashab, Osman Bakr, and Yu Han) have been elected as Fellows of the Royal Society of Chemistry for their work in materials science. Eddaoudi's work focuses on developing functional porous materials like KAUST-7 for carbon capture, aiming to reduce carbon emissions. Mohammed's group studies charge carrier dynamics at material surfaces. Why it matters: This recognition highlights KAUST's growing influence in advanced materials research and its contributions to addressing global challenges such as carbon capture and energy efficiency.
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 developed a water-stable MOF for energy-efficient dehydration, overturning conventional views. They also adapted high-resolution transmission electron microscopy to observe the atomic structure of metal-organic frameworks. KAUST hosted the Innovation to Impact Roundtable, fostering collaboration between academics and industry leaders from the U.S. and Saudi Arabia. Why it matters: These activities highlight KAUST's commitment to research breakthroughs, talent development, and fostering international collaborations in science and technology.
KAUST researchers have achieved a breakthrough by passing the damp-heat test for perovskite solar cells (PSCs), a rigorous assessment of their ability to withstand prolonged exposure to high humidity and temperatures. The team engineered 2D-perovskite passivation layers that block moisture and enhance power conversion efficiencies. The successful test, which requires maintaining 95% of initial performance after 1,000 hours at 85% humidity and 85 degrees Celsius, marks a significant step toward commercialization. Why it matters: This advancement addresses a critical weakness of PSCs and brings the technology closer to competing with silicon solar cells in terms of stability and longevity, crucial for widespread adoption of renewable energy.
