Researchers from King Abdullah University of Science and Technology (KAUST) and Aramco have achieved the highest reported efficiency in converting carbon dioxide into jet fuel-range hydrocarbons, a critical step for sustainable aviation fuel (SAF) development. Their work, published in ChemCatalysis, details a machine learning-driven approach that identified an unconventional copper-rich catalyst capable of yielding 75% jet fuel-range product and operating continuously for over 1,000 hours. The upgraded liquid fuel met key prescreening parameters aligned with international aviation standards, including flash point and energy content. Why it matters: This breakthrough offers a more efficient and stable pathway for producing SAF from captured CO₂, addressing a significant challenge in decarbonizing the hard-to-abate aviation sector.
Researchers at King Abdullah University of Science and Technology (KAUST) have demonstrated a novel method to permanently convert carbon dioxide (CO₂) into solid rock underground. This system recycles water already present deep underground, addressing the critical water scarcity challenge for CO₂ mineralization in arid regions. In a field trial in western Saudi Arabia, 131 tons of CO₂ were injected into ancient basalt formations, with approximately 70% mineralized into solid minerals within ten months. Why it matters: This breakthrough significantly expands the global potential for carbon mineralization as a secure CO₂ storage solution, particularly in water-stressed industrial areas.
KAUST researchers discovered that the red algae strain Galdieria yellowstonesis can convert sugars from chocolate-processing waste into C-phycocyanin, a valuable blue pigment. The study found that high levels of carbon dioxide promote Galdieria growth, and the resulting phycocyanin was deemed food-safe by the U.S. FDA. Mars supported the research by providing chocolate samples. Why it matters: This research offers a sustainable method for waste management and contributes to a circular economy in the region, with potential applications in food, cosmetics, and pharmaceuticals.
KAUST researchers have developed a system to convert captured carbon dioxide into industrial-grade ethylene using a high-pressure electrolyzer. The system operates under realistic industrial conditions and uses captured, high-pressure CO₂. It reduces the energy cost of producing ethylene by 0.8 gigajoules per metric ton compared to existing electrolysis systems. Why it matters: This innovation presents a direct path for transforming greenhouse gas emissions into valuable chemical products, aligning with Saudi Arabia's circular economy goals.
KAUST and KACST researchers have developed a nanoPE nanoplastic that improves LED streetlight energy efficiency by enhancing thermal radiation emission and reducing LED temperature. The nanoPE coating allows infrared light to pass through while reflecting visible light, optimizing illumination. Simulations suggest that adopting this technology in the US could reduce carbon dioxide emissions by over one million metric tons. Why it matters: This innovation offers a sustainable lighting solution with significant potential for reducing energy consumption and carbon emissions in Saudi Arabia and globally.
KAUST's Ibn Sina Distinguished Professor Carlos Duarte has been awarded the prestigious Japan Prize for his pioneering research on blue carbon and marine ecosystems. Duarte's work demonstrated the significance of marine ecosystems like seagrasses, mangroves, and salt marshes in sequestering and storing carbon dioxide. He coined the term 'blue carbon' and has advised Vision2030 initiatives. Why it matters: This award recognizes the importance of KAUST's research in marine conservation and highlights Saudi Arabia's growing role in ocean-based climate change solutions.
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.
Two KAUST professors, Sami Al-Ghamdi and Hussein Hoteit, have been selected as lead authors for the United Nations' Intergovernmental Panel on Climate Change (IPCC) Seventh Assessment Report (AR7). Al-Ghamdi will contribute to the Asia chapter, while Hoteit will focus on carbon dioxide removal technologies. The AR7 report is expected to be completed in 2029 and will inform international climate policy. Why it matters: This appointment places KAUST at the forefront of global climate research and strengthens the university's influence on international climate policy.
