KAUST researchers have developed a novel wastewater treatment method that recovers energy while removing ammonium. The process harnesses anammox bacteria to oxidize ammonium and generate electrical current or hydrogen gas. Pilot-scale reactors are being tested at KAUST, coupled with photovoltaic panels for solar-powered wastewater treatment. Why it matters: This approach could lead to more energy-efficient and sustainable wastewater treatment, aligning with circular economy principles.
J. Carlos Santamarina, a Professor of Earth Science and Engineering at KAUST, is researching geomaterial behavior and subsurface processes. His work focuses on energy geo-engineering, resource recovery, and geological storage of energy waste. He uses particle-level experiments, numerical methods, and monitoring systems to understand coupled thermo-hydro-bio-chemo-mechanically processes. Why it matters: This research contributes to energy sustainability and addresses global energy challenges through advanced geotechnology.
KAUST and King Abdulaziz University (KAU) are collaborating to develop low-cost sodium-ion battery technology using fly ash, a waste material from burning fossil fuels. Researchers are purifying fly ash and using thermal treatment to engineer its structure for use as carbon electrodes in batteries. The resulting carbon electrode material is competitive with existing market products and can be used for other applications. Why it matters: This research offers a sustainable approach to energy storage by repurposing waste materials, potentially enabling cheaper and more environmentally friendly grid-scale energy storage for renewable energy sources.
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.
KAUST Professor J. Carlos Santamarina is researching solutions to the global energy challenge, focusing on sustainable energy production while reducing CO2 emissions. He notes the increasing energy demand due to population growth and the limitations of current energy sources. Santamarina emphasizes the need for fuel-producing countries to participate in carbon capture and storage to meet carbon targets. Why it matters: This research contributes to addressing critical sustainability challenges in the region, especially in oil-producing countries like Saudi Arabia.
Nate Hagens from the University of Minnesota spoke at KAUST's Winter Enrichment Program (WEP) 2018 about the intersection of energy, human behavior, and economics. Hagens argued that society functions as an energy-dissipating "superorganism," with human preferences correlated with increasing energy needs. He emphasized that energy, not money, is the real capital, but global society is running out of it. Why it matters: The talk highlights the importance of viewing society through an ecological lens, particularly in the context of the GCC region's reliance on energy resources.
MIT Professor Ahmed F. Ghoniem delivered a keynote at KAUST's Spring Enrichment Program discussing clean energy solutions for future cities. He emphasized a portfolio approach including electrochemical, solar thermochemical, and plasma technologies for renewable energy storage. Ghoniem highlighted the economic opportunities arising from clean energy technology deployment, R&D, and job creation. Why it matters: The focus on renewable energy and storage aligns with Saudi Arabia's Vision 2030 goals for sustainable urban development and diversification of the energy sector.
KAUST researchers have developed an energy-efficient wastewater treatment process that generates high-quality effluent suitable for reuse. A pilot plant in Jeddah, operating since July 2022 in collaboration with MODON, treats 50,000 liters of wastewater daily off-grid, generating 1.5 kWh of electrical energy per 1,000 liters treated. The plant utilizes an anaerobic membrane bioreactor (AnMBR) coupled with UV disinfection, removing up to 99.9999% of microorganisms and producing less solid waste. Why it matters: This decentralized, energy-independent system offers a sustainable solution for water treatment in resource-scarce regions of the Middle East, aligning with Saudi Arabia's sustainability goals.
