A KAUST-led study has revealed a unique microbial ecosystem in the Hatiba Mons hydrothermal vent fields of the Red Sea, first documented in 2023. Using genome-resolved metagenomics, the study reconstructed over 300 microbial genomes from five vent sites. The analysis showed an ecosystem dominated by microbes capable of iron, sulfur, nitrogen, and carbon cycling, unlike most hydrothermal vents that are sulfur- and methane-based. Why it matters: The discovery provides new insights into microbial processes in extreme conditions, ocean resilience, and global carbon cycling, highlighting the interplay between geology and biology in the Red Sea.
Saudi Electricity Company (SEC) and KAUST have launched a pilot study at SEC’s Rabigh power plant to demonstrate a cryogenic technology that captures multiple pollutants and greenhouse gases, including carbon dioxide. The technology captures over 98% of carbon dioxide from flue gas, as well as sulfur dioxide, nitrogen oxides, and particulate matter, using a single system, unlike current technologies. The streamlined post-processing has a smaller environmental footprint and lower costs. Why it matters: This project supports Saudi Arabia's net-zero carbon goals and offers a potentially more efficient and cost-effective method for retrofitting existing power plants.
KAUST startup uODS signed an MoU with Saudi Aramco Base Oil Company (Luberef) to develop and deploy technology removing sulfur from hydrocarbons. The uODS process, based on KAUST's sonochemistry research, reduces sulfur in marine fuels to meet IMO 2020 regulations. Luberef aims to reduce its environmental footprint by piloting the uODS technology at its Jeddah refineries, with uODS set to produce 10 tons per day of desulfurized fuel for testing. Why it matters: The partnership demonstrates KAUST's role in addressing Saudi Arabia's environmental goals and showcases the potential of university spin-offs to contribute to a more sustainable oil industry in the region.
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.
KAUST is aligning its research, partnerships, and education with Saudi Arabia's Vision 2030 priorities, focusing on areas like energy transition, food security, and environmental resilience. A white paper released by KAUST outlines six focus areas including driving economic and industrial innovation and strengthening Saudi Arabia’s global scientific presence. Examples of KAUST initiatives include Cryogenic Carbon and Sulfur Co-capture (CCSC) technology and the KAUST Future Mobility Sandbox. Why it matters: This strategic alignment positions KAUST as a key player in advancing Saudi Arabia's national development goals through targeted research and innovation.
KAUST has developed AirGo, a hybrid air quality monitoring system using mobile and stationary sensors. The system measures gases (carbon dioxide, carbon monoxide, sulfur dioxide, ozone, etc.) and particulate matter, providing real-time environmental data. AirGo is at technology readiness level 6 and is being scaled up for broader use through partnerships with manufacturers. Why it matters: This technology directly supports Saudi Vision 2030's environmental sustainability goals and the development of smart cities by providing granular air quality insights.
KAUST researchers presented their work on stabilizing nanoparticle catalysts at the 252nd American Chemical Society Meeting & Exposition. The team devised a "molecular Scotch tape" using a silica gel support coated with a single molecule layer of soft material containing sulfur. This approach allows nanoparticles to stick to one side while leaving the other side free for catalysis, preventing aggregation without killing the catalyst. Why it matters: This innovation in catalyst stabilization could lead to more efficient and sustainable chemical processes, impacting various industries.
