Researchers investigated reinforcement learning (RL) for adaptive traffic signal control at an urban intersection in Kuwait, aiming to mitigate urban traffic congestion. They developed a Proximal Policy Optimization (PPO)-based controller that dynamically adjusts green-phase durations using local traffic states in a realistic simulation environment informed by real-world Kuwaiti traffic data. The controller reduced average vehicle delay by 46% relative to fixed-time control and 34% relative to actuated control, while also lowering per-vehicle CO2 emissions by approximately 23%. Why it matters: This demonstrates a practical, learning-based edge traffic signal control solution for IoT-enabled smart city transportation systems, offering significant improvements in traffic flow and environmental impact for car-dependent cities in the Middle East.
Technology Innovation Institute (TII) has launched a blockchain-powered carbon tracking and trading platform at COP28. The platform, designed by TII’s Cryptography Research Center (CRC), aims to facilitate international trade in carbon tokens and promote green investment. It uses a lightweight, efficient blockchain implementation for transparent and secure verification of tracking and trading activities. Why it matters: The platform supports the UAE's sustainability goals and contributes to the global effort to achieve net-zero emissions by enabling verifiable and trustworthy carbon trading.
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 and KACST researchers have developed a nanoPE nanoplastic that improves LED streetlight energy efficiency by enhancing thermal radiation emission and reducing LED temperature. The nanoPE coating allows infrared light to pass through while reflecting visible light, optimizing illumination. Simulations suggest that adopting this technology in the US could reduce carbon dioxide emissions by over one million metric tons. Why it matters: This innovation offers a sustainable lighting solution with significant potential for reducing energy consumption and carbon emissions in Saudi Arabia and globally.
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, 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.
ClimateCrete, a KAUST spinout, has raised investment for its technology that modifies sand particles to make them suitable for concrete manufacturing. The patented tech reduces the need for cement and lowers CO2 emissions by up to 60 percent. Tests show a significant increase in strength compared to untreated sand. Why it matters: This technology addresses the global shortage of suitable construction sand and supports Saudi Arabia's carbon-neutrality goals by enabling a 100% domestic supply chain for concrete.
KAUST researchers led by Yves Gnanou and Nikolaos Hadjichristidis have developed a metal-free process for creating aliphatic degradable polycarbonates using CO₂. This polycarbonate is transparent, highly flexible, and produced without toxic metals, using an ammonium compound and a boron-based compound. The process helps reduce plastic pollution and CO₂ emissions, addressing environmental concerns. Why it matters: This innovation offers a sustainable alternative to traditional plastic production, aligning with global efforts to reduce reliance on harmful materials and combat climate change.
