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.
Matthew McCabe, director of the KAUST Climate and Livability Initiative (CLI), and his team have been awarded the 2022 Prince Sultan Bin Abdulaziz International Prize for Water in the Water Management and Protection category. The award recognizes their innovative use of satellites for water accounting and management, harmonizing data from CubeSat satellite platforms. They produced the highest resolution estimates of water usage ever retrieved from space, using data from Planet's constellation of small satellites. Why it matters: This award highlights the growing role of remote sensing technologies and KAUST's leadership in addressing critical climate and sustainability issues in water resource management within Saudi Arabia and globally.
KAUST's Urban Lab is developing the Saudi National Life Cycle Inventory, an environmental database providing quantitative data on the environmental impact of products and processes in Saudi Arabia. The database includes information on raw material use, energy consumption, water usage, waste generation, and air pollutants specific to the Kingdom. This project was highlighted at the 'Greening the Giga' workshop, where KAUST also released a report on building a national framework for Life Cycle Assessments. Why it matters: The database and framework can guide multiple sectors in adopting green technology and help Saudi Arabia achieve its net-zero carbon emissions goal by 2060.
KAUST's Hydrology and Land Observation (Halo) lab, led by Matthew McCabe, is using drones and satellites to monitor agricultural water usage in Saudi Arabia. They employ thermal cameras, sensors, and imagery from CubeSats to map crop types, health, and water stress. The team uses machine learning and AI to analyze the images, aiming to promote sustainable water management. Why it matters: This research addresses critical water scarcity issues in the region by providing data-driven insights for more efficient agricultural practices.
