Scientists from Hamad Bin Khalifa University in Qatar have designed an innovative solar-driven system to manage brine efficiently and produce hydrogen. The system combines various technologies such as photovoltaic-thermal panels, reverse osmosis desalination, reverse electrodialysis, and proton exchange membranes. By utilizing the energy produced, the system can provide cooling and generate electricity and hydrogen. Additionally, a photo-chloralkali process converts leftover brine into hydrogen, chlorine, and sodium hydroxide. The system's thermodynamic assessment revealed promising energy and exergy efficiencies, with a focus on hydrogen and freshwater production. The researchers emphasized the importance of integrated solutions to address environmental challenges while meeting energy needs. This groundbreaking study was published in the International Journal of Hydrogen Energy, showcasing the potential for sustainable energy innovation in the field.
