KAUST researchers found that sulfate ions reduce free water in aqueous batteries, mitigating parasitic reactions that degrade the anode and shorten battery life. Adding zinc sulfate increased battery lifespan by more than ten times. Sulfate salts stabilize the bonds of free water, acting as a "water glue" to reduce parasitic reactions. Why it matters: This finding provides a cheap and scalable approach to improve the viability of aqueous batteries for sustainable energy storage, particularly for integrating renewable energy sources.
KAUST and Aramco are partnering to develop extreme temperature-resilient batteries for subsurface applications and the hot climate of Saudi Arabia. The new batteries aim to operate effectively from subzero to 130°C, addressing the limitations of traditional lithium-based batteries that degrade above 60°C. KAUST is focusing on identifying electrolytes and separators that can endure high temperatures, while Aramco provides operational expertise. Why it matters: This collaboration could lead to significant cost savings in the energy sector, improve battery performance in EVs and grid systems, and position Saudi Arabia as a leader in advanced battery technology for extreme environments.
KAUST has launched a Center of Excellence (CoE) for Renewable Energy and Storage Technologies, chaired by Professor Husam Alshareef, to develop and deploy innovative renewable energy and storage technologies. The center will focus on homegrown technologies invented at KAUST and aims to attract investments, partnerships, and market interest for commercial adoption. Research will focus on prototyping and scaling technologies across six key themes including advanced photovoltaics and new battery chemistries. Why it matters: This initiative aligns with Saudi Vision 2030, supporting the Kingdom's climate goals and transition to sustainable energy while creating jobs and enhancing energy security.
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.
A KAUST team led by Husam Alshareef has developed a microfabricated energy storage device with high energy and power density. The device uses nickel hydroxide as an active electrode material and achieves a volumetric capacitance density of 325 F/cm3. Fabricated using chemical bath deposition at room temperature, the device can power microelectronic devices. Why it matters: This research advances energy storage technology in the region, potentially impacting the development of microelectronics and portable power solutions.
KAUST hosted the Frontiers in Energy Storage 2026 conference, emphasizing energy storage technologies for renewable energy. The conference highlighted electrochemical and chemical systems, including advanced batteries and hydrogen, as complementary layers for long-duration and industrial resilience. KAUST is developing energy-storage solutions relevant for the Kingdom and valuable to global partners, aiming to engineer solutions to withstand extreme environmental temperatures. Why it matters: This positions Saudi Arabia as a potential global exporter of resilient energy hardware, aligning with Saudi Vision 2030 goals in renewable energy.
KAUST Professor Mohamed Eddaoudi has won the 2023 Kuwait Prize in chemistry for his work on functional solid-state materials, specifically metal-organic frameworks (MOFs). His research focuses on innovative design strategies for these materials and their applications in gas separations, catalysis, energy storage, and carbon capture. Eddaoudi, a founding faculty member at KAUST since 2009, shares the prize with Prof. Nashaat Nassar from the University of Calgary. Why it matters: The award recognizes KAUST's research excellence and highlights the importance of materials science for energy and environmental sustainability within the Arab world.
KAUST alumna Dr. Dalal Alezi has been awarded the Ibn Khaldun Fellowship for Saudi Women at MIT to pursue postdoctoral research in energy storage and water capture materials. She completed her Ph.D. at KAUST under Professor Mohamed Eddaoudi, focusing on metal-organic materials for gas separation, storage, catalysis, and drug delivery. Alezi credits KAUST and KAU for supporting her career and shaping her role as a mentor for incoming science students at KAU. Why it matters: The fellowship recognizes and supports talented Saudi women in STEM, promoting advancements in materials science and inspiring future generations of Saudi scientists.
