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 are developing new solar desalination methods to increase efficiency and minimize heat losses, building on techniques dating back to Arab alchemists. KAUST Associate Professor Peng Wang and his team at the Water Desalination and Reuse Center are developing an innovative system that more efficiently vaporizes water using interfacial heating. The design uses a photothermal material to capture the entire spectrum of sunlight and convert it into heat with nearly 100% efficiency. Why it matters: This research could provide more sustainable and efficient methods for producing fresh water in arid regions like the Middle East.
A hybrid desalination pilot plant combining adsorption and multi-effect distillation cycles is under construction at KAUST. The integration aims to improve water production yields by up to three times using the same heat resource. The project is funded by a 2013 OCRF grant and builds upon previous research with a solar-powered adsorption pilot plant. Why it matters: This initiative advances sustainable desalination technologies, crucial for water security in arid regions like Saudi Arabia.
A KAUST and King Abdulaziz University research team is using superhydrophobic sand to grow crops like tomatoes with less water. Superhydrophobic sand reduces water consumption in agriculture, the world's largest consumer of freshwater. The sand was developed by KAUST's Himanshu Mishra and Ph.D. student Adair Gallo Junior. Why it matters: This research offers a promising solution for water conservation in agriculture, especially in arid regions like the Arabian Peninsula, addressing critical water security challenges.
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's Water Desalination and Reuse Center (WDRC) is developing solar-powered seawater desalination technologies, including the MEDAD cycle which combines adsorption desalination (AD) and multi-effect distillation (MED). The MEDAD cycle, developed by Professor Kim Choon Ng, doubles water production at the same temperature, reducing costs to $0.48/m3 compared to $1.201/m3 for multi-stage flash distillation. A 100 m3/day commercial-scale MEDAD project was commissioned in Riyadh in 2017 in collaboration with KACST, and a larger 2,000 m3/day project is planned for Yanbu. Why it matters: This highlights Saudi Arabia's move towards sustainable energy and the role of research institutions like KAUST in developing cost-effective desalination technologies suitable for the region.
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.
