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 researchers are working on green hydrogen production, which uses renewable energy to split water into hydrogen and oxygen. The current methods are capital intensive and require desalinated water, which is scarce in desert regions. KAUST is partnering with NEOM, a futuristic region on the Red Sea, where green hydrogen will be an important part of the economy. Why it matters: Innovations in green hydrogen production and cost reduction will be critical for sustainable energy in regions like Saudi Arabia.
KAUST researchers have developed a method using high-intensity pulses of light to remove carbon-based organic micropollutants from wastewater. By using a pulsed light system previously used for semiconductor materials, the team dramatically accelerated the photodegradation treatment. The high-intensity pulsed light (HIPL) triggers decomposition of organic micropollutants (OMPs) with extraordinary degradation rates within milliseconds. Why it matters: This treatment offers a potentially scalable solution to the increasing environmental problem of OMPs in waterways, addressing a critical need in water treatment technologies for the region.
KAUST Catalysis Center (KCC) and KAUST Solar Center (KSC) partnered with Nigerian startup Newdigit Technologies to develop their "Just Add Water" pilot. The project aims to use electrolysis powered by photovoltaics to split water into hydrogen (for cooking) and oxygen. The hydrogen produced can be utilized as a clean-burning gas for cooking, while the fuel cell generates electricity and produces clean drinking water. Why it matters: This collaboration highlights KAUST's role in fostering sustainable energy solutions for developing nations and addressing critical challenges like energy access and indoor air quality.
KAUST Ph.D. student Hui-Chun Fu and postdoctoral fellow Purushothaman Varadhan won awards at the 2018 NANO Conference in Hong Kong for their photoelectrochemical research. They received the Materials Today Rising Star Poster Award (Silver) and the NANO2018 Session Theme Poster Award. Their research focuses on converting solar energy into storable fuels like hydrogen through solar-driven water splitting. Why it matters: This recognition highlights KAUST's contributions to renewable energy research, crucial for the GCC's transition to sustainable energy sources.
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.
John Pantoja from the Directed Energy Research Center at TII presented a method to estimate the effects of high current impulses on electro-conductive textiles. The method uses specific action, a parameter to determine burst of exploding wires, and a new equivalent electrical circuit. The model estimates the current intensity needed to melt the conductive layer at contact areas between yarns, and is validated experimentally on ripstop woven fabrics. Why it matters: The research explores conductive fabrics for portable lightning protection shelters, potentially reducing lightning-related accidents in high-risk populations.
KAUST researchers used electron tomography and X-ray photoelectron spectroscopy to study charge storage in manganese oxide electrodes for supercapacitors. They found that the electrolyte etches nanoscale openings in the manganese oxide sheets, increasing electrolyte permeability and energy density during cycling. 3D tomography revealed how the electrode's morphological evolution increases its surface area, enhancing energy densities. Why it matters: The research provides insights into improving the cycling stability of pseudocapacitive materials, which are crucial for developing high-performance supercapacitors.
