Engineers at Hamad Bin Khalifa University in Qatar have developed a groundbreaking desalination system that goes beyond just providing fresh water. This modularized system is capable of producing electricity, hydrogen, and cool air for refrigeration. The system starts with bifacial c-Si PV panels that can generate up to 1.5 MW of electricity, with a portion used for direct energy supply and the rest for precooling groundwater. Additionally, a vapor compressor module is used to chill saline water until ice crystals form, which are then turned into fresh water through a process that removes salt. The ice is stored and used for air conditioning by chilling air pumped into buildings. Another module purifies water further using electro-deionization and an electrolyzer to produce hydrogen gas. The system operates during the day for desalination and air conditioning, while the electrolyzer runs at night to produce hydrogen for energy storage. This innovative system has significant daily outputs, including electricity, fresh water, and hydrogen, making it a sustainable solution for areas facing water scarcity and energy needs.
