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.
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 and TU Munich researchers have published a paper on a novel carbon capture technique. The technique focuses on converting CO2 directly from flue gas using catalytic systems, addressing the challenge of CO2 conversion requiring purification, compression, and high temperatures. Catalysts are often seen as viable green technology options to increase the renewable rates of CO2. Why it matters: This research has the potential to advance sustainable energy solutions by improving the efficiency and reducing the environmental costs associated with carbon capture and utilization.
A KAUST-led multidisciplinary research team is studying the feasibility of storing CO2 in subsurface rock structures in Saudi Arabia, specifically in Harrat near Madinah. The project, conducted under the auspices of the Saudi Ministry of Economy and Planning, involves researchers from KAUST, King Abdulaziz University, and MEP. The team is investigating carbon capture and storage as a means to address climate change and meet Saudi Vision 2030 goals. Why it matters: This research could provide a pathway for Saudi Arabia to reduce CO2 emissions and contribute to global climate change mitigation efforts, aligning with the Kingdom's commitment to the Paris Climate Agreement.
KAUST is developing portable, containerized cryogenic carbon capture (CCC) technology for industrial emissions reduction. The system captures CO2 and SO2, offering a modular design for ships and other applications, with post-processing done onshore. KAUST and SEC launched a demonstration exercise in November 2024 showcasing the technology. Why it matters: This innovation could significantly reduce the carbon footprint of industries and maritime transport in line with Saudi Arabia's sustainability goals.
