Researchers from Hamad Bin Khalifa University in Qatar have proposed an innovative PV-powered system for sustainable agriculture in desert environments. This standalone system integrates various functions, including water desalination, green hydrogen production, air conditioning, and electricity production, all powered by bifacial c-Si PV panels. The system's design is aimed at addressing the challenges faced by agricultural activities in remote desert locations, such as high water and energy demands and inadequate infrastructure. By simulating the system's performance based on thermodynamic principles, the researchers demonstrated its potential to provide essential commodities for agriculture in desert climates. The system operates continuously, utilizing freeze desalination and ice storage to generate ice for air conditioning and water for agriculture. Additionally, it produces hydrogen through a PEM water electrolyzer and stores it in metal hydride tanks for later use in a fuel cell during periods of low solar energy availability. The system's energetic efficiency is calculated at 17.8% during the day and 56% at night, emphasizing the importance of efficient energy utilization. Overall, this innovative system offers a sustainable and efficient solution for agricultural activities in challenging desert environments, aiming to optimize the utilization of solar energy and water resources for the benefit of farmers and the environment.
