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 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 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.
Researchers from KAUST and University of Toronto have created a two-sided perovskite/silicon tandem solar cell that exceeds the performance limits for tandem configurations. The bifacial design captures both direct sunlight and light reflected from the ground (albedo). Outdoor testing demonstrated efficiencies beyond commercial silicon solar panels. Why it matters: This innovation promises ultra-high power generation at affordable costs, potentially revolutionizing the photovoltaics market in the region and globally.
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 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 led by Pascal Saikaly are developing microbial electrochemical technologies (METs) for wastewater treatment and energy recovery. The team combines METs with membrane filtration, creating a hybrid air-biocathode microbial fuel cell-membrane bioreactor (MFC-MBR) for simultaneous wastewater treatment and ultrafiltration. This system uses an electrically conductive ultrafiltration membrane as a biocathode for electricity generation and passive oxygen transfer. Why it matters: This innovation offers a sustainable approach to water reclamation by reducing energy consumption and producing reusable water, which addresses critical water scarcity challenges in the region and globally.
KAUST, NEOM’s Education, Research, and Innovation Foundation (ERIF), and ENOWA have formed a partnership to support Saudi Arabia’s hydrogen economy. ERIF has sponsored three strategic projects under its Hydrogen and e-Fuels Applied Research Institute (HEFARI) with KAUST researchers focusing on developing hydrogen as a renewable energy vector. The projects cover carbon-neutral fuels, cost-effective electrolyzer technologies, and lowering emissions from green ammonia. Why it matters: This collaboration aims to establish Saudi Arabia as a leader in green hydrogen technologies and sustainable fuel production, aligning with the Kingdom's decarbonization goals.
