This study introduces a reinforcement learning (RL) framework using Proximal Policy Optimization (PPO) and Soft Actor-Critic (SAC) to optimize the cleaning schedules of photovoltaic panels in arid regions. Applied to a case study in Abu Dhabi, the PPO-based framework demonstrated up to 13% cost savings compared to simulation optimization methods by dynamically adjusting cleaning intervals based on environmental conditions. The research highlights the potential of RL in enhancing the efficiency and reducing the operational costs of solar power generation.
Researchers at KAUST and KACST have developed a composite material that enhances solar cell performance by absorbing air moisture at night and releasing it during the day. When applied to solar cells in Saudi Arabia, the material increased power output by 12.9% and extended cell lifespan by over 200%. The passive cooling technology also reduced electricity generation costs by 18%. Why it matters: This innovation addresses a key challenge in solar energy adoption in hot climates, potentially making solar power more efficient and cost-effective in the region.
KAUST and ACWA Power have launched a Center of Excellence for Desalination and Solar Power following a memorandum of understanding signed on September 9. The collaboration aims to advance Saudi Arabia's position in water desalination and solar power technology. The center will focus on research in water quality monitoring and system performance modeling, leveraging KAUST's research centers. Why it matters: The partnership seeks to drive innovation and cost efficiencies in producing desalinated water and generating solar power, aligning with Saudi Arabia's sustainability goals.
KAUST led a session at the World Economic Forum's Meeting of the New Champions in Dalian, China, focusing on sustainability science. President Tony Chan and faculty members Peiying Hong, Mohamed Eddaoudi, and Derya Baran presented KAUST's research in water reuse, carbon capture, and transparent solar cells. Derya Baran highlighted KAUST spinoff iyris, which aims to turn windows into solar power plants. Why it matters: This showcases KAUST's role as an innovative hub for global research and education, particularly in green technologies, and highlights the university's commitment to addressing environmental challenges.
Wail Bamhair (M.S. '10, electrical engineering) is the CEO of TAQNIA Energy, the energy arm of Saudi Investment and Development. He joined TAQNIA as its first employee after the CEO, eventually leading the development of Saudi Arabia's first independent solar power station, Layla Power Station (50 MW). Prior to TAQNIA, he worked at King Abdullah City for Atomic and Renewable Energy (K●A●CARE). Why it matters: This highlights the role of KAUST graduates in driving Saudi Arabia's renewable energy sector and contributing to Vision 2030's sustainability goals.
KAUST's New Energy Oasis (NEO) hosted an open day on May 7 to showcase its renewable energy technologies. The event featured guided tours of the NEO site, where 11 international technology providers are testing renewable energy solutions. The technologies on display included photovoltaic (PV), concentrating solar power (CSP), and dust mitigation technologies. Why it matters: This initiative helps identify and implement the most appropriate renewable energy technologies for Saudi Arabia, addressing the Kingdom's growing energy demands.
NOMADD, a KAUST startup, offers a waterless and remotely operated system to clean solar panels, addressing the challenge of dust accumulation which can reduce solar panel efficiency by 0.4-0.8% daily. KAUST recently signed its first royalty-bearing license agreement for the NOMADD system. The fifth version of the NOMADD system is 70% lighter and uses less than half the power of previous versions, while also being cheaper to manufacture. Why it matters: This technology is crucial for Saudi Arabia to achieve its ambitious goal of generating a third of its electricity from solar power by 2032, amidst the challenges posed by desert dust.
Boeing has inaugurated a new Research & Technology office at KAUST's Research and Technology Park, marking Boeing's first research center in a university within the GCC. The office will focus on R&D in aerospace technologies, building on Boeing's partnership with KAUST since 2009. Boeing is currently collaborating with KAUST on six major projects in areas like advanced materials and solar power. Why it matters: The establishment of this office signifies a deepened commitment to R&D in Saudi Arabia and the region, leveraging KAUST's resources to advance aerospace technologies.
