The Oil Sustainability Program (OSP), in partnership with PIF, SIRC, NEOM, SIKA, and ClimateCrete, has launched the "NovusCrete" Consortium to innovate in sustainable concrete solutions. The initiative prioritizes localization using materials like seawater, recycled construction waste, and fine sand, supported by entities like the American Concrete Institute (ACI). ClimateCrete, a KAUST spin-off, uses patented technology to transform fine sand into high-quality concrete sand, reducing cement use and CO2 emissions by up to 60%. Why it matters: The consortium and ClimateCrete's technology represent significant steps towards sustainable construction practices in the region, aligning with Saudi Arabia's carbon neutrality goals and fostering a deep-tech startup ecosystem.
KAUST researchers have developed a new technology for direct lithium extraction from brine in oilfields and seawater, potentially positioning Saudi Arabia as a major lithium producer. The technology, demonstrated at a pilot scale, allows extraction from low-concentration sources (as low as 20 parts per million) without pollutants. It could increase global lithium resources from 22 million tons to over 230 billion tons. Why it matters: This innovation could transform Saudi Arabia from a lithium importer to a producer, strengthening its energy security and influence in the global clean energy market.
KAUST researchers have developed new techniques to produce nutritious microalgae in industrial volumes using seawater-adapted Spirulina and Chlorella strains. This innovation eliminates the need for freshwater, making algae-based livestock feed production sustainable and economically viable. The new Saudi Center for Algal Biotechnology Development and Aquaculture will scale up operations from a 1,000 square meter pilot plant to 42,000 square meters. Why it matters: This could help Saudi Arabia decrease its dependency on imported feed and raw food materials, aligning with its Vision 2030 goals for increased domestic food security.
KAUST startup Lihytech has raised US$6 million in funding from Ma'aden and the KAUST Innovation Ventures Fund. Lihytech's patented membrane technology, developed by Professor Zhiping Lai at KAUST, extracts battery-grade lithium from sources like seawater. The funding will be used to build a pilot facility at KAUST to extract lithium from the Red Sea and other in-Kingdom resources. Why it matters: This investment supports Saudi Arabia's goal of developing a complete electric vehicle value chain and becoming a key player in meeting global lithium demand.
KAUST researchers led by Mark Tester are developing new irrigation technology to enable crop production using semi-saline water, aiming to reduce freshwater reliance to 10% in greenhouse systems. The technology is eco-friendly and intends to cut agricultural costs by utilizing seawater, targeting a cost of 10 U.S. cents per cubic meter. A new company named Red Sea Farms is being developed to grow salt-tolerant tomatoes in diluted seawater in a greenhouse cooled with undiluted seawater. Why it matters: This research could significantly reduce pressure on freshwater resources in arid regions and offers a sustainable approach to increase food production using available seawater.
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 and the Oil Sustainability Program (OSP) have signed two agreements focused on sustainability assessments and methodologies, including life-cycle assessment (LCA) and life-cycle cost (LCC) modeling for seawater concrete technology. The collaboration aims to strengthen national sustainability capabilities, improve data quality, and standardize assessment frameworks in line with Saudi Vision 2030. A KAUST-hosted workshop convened global experts to advance the adoption of LCA for sustainable development in Saudi Arabia, also launching EPD Saudi Arabia. Why it matters: The partnerships and initiatives signal a commitment to integrating sustainability into industrial and infrastructure development in Saudi Arabia, aligning with the Kingdom's broader environmental goals.
KAUST researchers have developed a new solar distillation device that prevents salt accumulation by using a centimeter-scale plastic cube containing glass fiber membranes and carbon nanotubes. The design incorporates vertically oriented membranes with hydrophilic microchannels to transport seawater to the top solar layer for distillation. This elevated design doubles the freshwater production rate compared to existing salt-rejection solar stills. Why it matters: This innovation improves the efficiency and longevity of solar-powered desalination, offering a sustainable solution for water purification in emergency situations and remote areas.
