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.
The Red Sea Development Company (TRSDC) and KAUST have signed a Master Research Agreement (MRA) to collaborate on sustainability research. Prior collaborations included flora and fauna assessments and the Brains-for-Brine Challenge. The MRA focuses on marine environments, waste management, food production, energy conservation, and carbon sequestration. Why it matters: This partnership aims to develop regenerative tourism practices, preserve the Red Sea's biodiversity, and establish a model for sustainable tourism in the region.
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.
KAUST researchers and German collaborators explored the Red Sea's depths using the RV Meteor, employing ROVs and seismic equipment to map geological and biological features. They examined underwater hot springs, microbial mats, and deep-sea brine pools, discovering hydrothermal vent fields with unique ecosystems. The research, involving multidisciplinary teams, provides insights into the Red Sea's geology, ecosystems, and biodiversity. Why it matters: Studying the Red Sea's unique environment can offer valuable knowledge about young ocean development and novel marine ecosystems, relevant for understanding similar geological formations and biodiversity hotspots in the region.
KAUST and Japan's NHK have signed an agreement for NHK to film the Red Sea in 8K high-definition as part of the "Deep Ocean" documentary series. The filming will be coordinated with researchers from KAUST's Red Sea Research Center, covering a range of subjects from coral reefs to deep-sea brine pools. The collaboration, initiated in 2019, was delayed due to the COVID-19 pandemic. Why it matters: This partnership will showcase the Red Sea's unique biodiversity and KAUST's marine research capabilities to a global audience, highlighting Saudi Arabia's focus on environmental research and its Red Sea giga-projects.
KAUST Professor Peng Wang has been awarded the 2020 Prince Sultan Bin Abdulaziz International Prize for Water (PSIPW). Wang's research focuses on using solar energy for fresh-water generation, industrial brine treatment, atmospheric water harvesting, and solar PV cooling. His recent work involves a hydrogel cooling panel for solar cells to improve efficiency in hot climates. Why it matters: This award recognizes impactful research addressing water scarcity and energy challenges in arid regions like Saudi Arabia through innovative solar-driven technologies.
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.
