KAUST scientists discovered a new brine pool in the Red Sea, named the Afifi pool, in collaboration with Saudi Aramco. The Afifi pool is the saltiest known in the Red Sea, six times saltier than surrounding seawater, and is located at a depth of 400 meters. Researchers used a variety of tools including Niskin bottles, an Idronaut CTD, and the Research Vessel Thuwal to characterize the pool's physical and chemical properties and sample its microbiology. Why it matters: This discovery facilitates understanding of the geochemistry and microbiology of extreme ecosystems, potentially aiding in the sustainable conservation of the Red Sea and offering insights into potential extraterrestrial environments.
KAUST researchers have developed a new technology for direct lithium extraction from brine in oilfields and seawater, potentially positioning Saudi Arabia as a major lithium producer. The technology, demonstrated at a pilot scale, allows extraction from low-concentration sources (as low as 20 parts per million) without pollutants. It could increase global lithium resources from 22 million tons to over 230 billion tons. Why it matters: This innovation could transform Saudi Arabia from a lithium importer to a producer, strengthening its energy security and influence in the global clean energy market.
Aramco and KAUST-incubated startup Lihytech are collaborating to develop Direct Lithium Extraction (DLE) technology in Saudi Arabia. Aramco is providing oilfield brines to Lihytech to assess their lithium extraction technology at KAUST Research and Technology Park. The collaboration supports Saudi Arabia's Vision 2030 and its growing demand for lithium in electric vehicles. Why it matters: This partnership could unlock a new critical mineral industry in Saudi Arabia, leveraging existing oilfield resources for sustainable lithium production.
KAUST's Salt Lab, led by Professor Mark Tester, is researching how salt-tolerant plants survive in harsh environments. The lab aims to improve plant yields in suboptimal conditions, focusing on naturally occurring variability in plants to enhance salinity tolerance. With 70% of global water used for agriculture and increasing water scarcity, the research seeks to unlock the potential of seawater for irrigation. Why it matters: Enhancing the salinity tolerance of crops is crucial for addressing food security challenges exacerbated by climate change and the growing global population, particularly in arid regions like the Middle East.
KAUST researchers have developed an ultrathin polymer-based membrane for water desalination with high water flux and salt rejection. The membrane utilizes two-dimensional porous carbonaceous materials with subnanometer-sized molecular transport channels. The membrane outperformed existing desalination systems using carbon nanotubes and graphene in forward and reverse osmosis. Why it matters: This innovation offers a promising alternative for efficient and cost-effective desalination, addressing critical water scarcity challenges in the region and beyond.
KAUST researchers have developed a new solar distillation device that prevents salt accumulation by using a centimeter-scale plastic cube containing glass fiber membranes and carbon nanotubes. The design incorporates vertically oriented membranes with hydrophilic microchannels to transport seawater to the top solar layer for distillation. This elevated design doubles the freshwater production rate compared to existing salt-rejection solar stills. Why it matters: This innovation improves the efficiency and longevity of solar-powered desalination, offering a sustainable solution for water purification in emergency situations and remote areas.
KAUST researchers are developing innovative solutions for water treatment and desalination in Saudi Arabia. A pilot anaerobic membrane bioreactor in Jeddah treats 50,000 liters of wastewater daily at zero energy cost, producing water suitable for reuse and liquid fertilizer. Another KAUST team focuses on advancing desalination technologies by integrating renewable energy and reducing energy consumption and brine discharge. Why it matters: These advancements can significantly contribute to Saudi Arabia's water security and sustainability goals by reducing reliance on non-renewable groundwater and fossil fuels for desalination.
The Robotics, Intelligent Systems, and Control (RISC) lab at KAUST is developing swarm robotics, enabling robots to work together on collaborative tasks with limited human supervision. RISC is using game theory to improve how robots make coordinated decisions in scenarios like engaging intruders or tracking oil spills. The lab is also researching programmable self-assembly for robot swarms. Why it matters: This research advances autonomous multi-agent systems for critical applications like search and rescue and environmental monitoring in the region.
