KAUST researchers have developed a saliva-powered microbial fuel cell (MFC) that generates electricity using electrogenic bacteria to consume waste and release electrons. The micro-MFC uses graphene as an anode and an air cathode, achieving high current densities (1190 A m-3). The MFC produced 40 times more power than through the use of a carbon cloth anode. Why it matters: This technology offers a novel way to power lab-on-chip or portable diagnostic devices, particularly in remote or dangerous areas, and may offer alternatives to energy-intensive water purification technologies.
KAUST researchers are simulating cyberattacks on microgrids to assess their impact and develop detection/suppression methods. They used the Canadian urban distribution model with four inverter-based distributed generations (DGs) to capture system dynamics. The simulations considered attacks altering measurement data, modifying control signals, and causing sudden load changes, all of which had damaging effects. Why it matters: This research is crucial for ensuring the resilience of increasingly complex microgrids against cyber threats, especially as they become more integrated into critical infrastructure.
Dr. Leslie Dewan, co-founder and CEO of Transatomic, spoke at KAUST's Winter Enrichment Program about next-generation sustainable nuclear power plants. Dewan advocates for both nuclear and renewable energy to meet energy demands. She believes her company's new reactor design, which uses better fuel and reduces nuclear waste, is ideal for countries with rising power demands like Saudi Arabia. Why it matters: This highlights KAUST's engagement with innovative energy solutions and their potential relevance to Saudi Arabia's future energy strategy.
A KAUST-led team developed a nano-optical chip capable of generating and controlling nanoscale rogue waves. The chip, detailed in Nature Physics, uses a planar photonic crystal fabricated at the University of St. Andrews and tested at FOM Institute AMOLF. It enables unprecedented control over these rare, high-energy events, opening possibilities for energy research and environmental safety. Why it matters: This innovation provides a new platform for studying extreme events and potentially harnessing their energy, advancing both fundamental science and practical applications in areas like renewable energy and disaster prevention.
Dr. Giampiero Marchegiani from the Quantum Research Center (QRC) co-authored a paper in Nature Nanotechnology on bipolar thermoelectricity in Josephson junctions. The research demonstrates the generation of electrical current using heat, observing bipolar thermoelectricity where the device generates either positive or negative electrical signals without extra control. Integrating these junctions into a bipolar thermoelectric Josephson engine (BTJE) allowed the generation of up to ~140nW/mm2 of electric power at subkelvin temperatures. Why it matters: This BTJE engine may have applications in superconducting technology, potentially strengthening the UAE's position in quantum technologies.
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.
KAUST and GE have partnered to study the feasibility of using crude oils like Arabian Super Light (ASL) to power heavy-duty gas turbines. The collaboration aims to develop turbines capable of burning crude oil directly from the ground to meet Saudi Arabia's energy security needs. The research involves building a rig at KAUST's High Pressure Combustion Laboratory (HPCL) to conduct corrosion tests on turbine materials by burning ASL/AXL crude continuously for 2,000 hours. Why it matters: This partnership could reduce reliance on natural gas and offer an economically viable alternative fuel source, bolstering energy security in Saudi Arabia and potentially influencing turbine technology worldwide.
William Tang from Princeton spoke at KAUST about using deep learning to achieve nuclear fusion. Nuclear fusion, recreating stellar conditions on Earth, is considered the "holy grail" of power sources because it is clean and does not produce radioactive waste. Tokamaks, invented by Soviet physicists, are devices used to contain plasma, the superheated ionized gas required for fusion. Why it matters: KAUST is contributing to research on sustainable energy solutions, including exploring the potential of AI in nuclear fusion, a potentially transformative clean energy source.
