| description | <p dir="ltr">This study introduces an innovative approach to enhance operational efficiency and reduce the energy consumption of <u>seawater desalination</u> through <u>electrodialysis</u> (ED) by expanding the beneficial outputs beyond desalinated water. In addition to hydrogen (H<sub>2</sub>) gas production, the system is designed to generate nutrient-rich water for hydroponic farming by selectively recovering essential ions from <u>seawater</u>. The core innovation lies in integrating Monovalent Selective Membranes-Electrodialysis (MVS-ED) with ion-exchange resins (IEX-R). The new configuration allows for the selective removal of <u>monovalent ions</u> while preventing the leakage of multivalent ions such as magnesium and calcium, which are captured by the IEX-Rs. The ED cell simultaneously generates <u>h</u><u>ydrogen gas</u> at the cathode, with the separation of anolyte and <u>catholyte</u> solutions facilitating efficient gas collection. Several experiments are conducted using seawater under varying current densities and voltages, achieving a 96.23% removal of harmful ions (NaCl) from the seawater. The results reflect that the maximum H<sub>2</sub> gas generation rate achieved is 18 mmol/h while applying 15 mA/cm<sup>2</sup> of current density and 8 V of applied potential. The system's minimum net energy consumption was calculated as 6.43 kWh/m<sup>3</sup> of desalinated seawater with the benefit of producing carbon-free H<sub>2</sub> gas. The <u>specific energy</u> consumption for ion removal was 0.521 kWh/g, with energy and <u>exergy efficiencies</u> of 20.73% and 29.57%, respectively. This integrated MVS-ED and IEX-R system represents a significant advancement in sustainable <u>desalination technology</u>, offering a dual benefit of clean energy production and nutrient recovery, paving the way for resource-efficient agricultural practices and a sustainable future.</p><h2>Other Information</h2><p dir="ltr">Published in: International Journal of Hydrogen Energy<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.ijhydene.2024.12.170" target="_blank">https://dx.doi.org/10.1016/j.ijhydene.2024.12.170</a></p> |
