| Abstract |
This review tries to differ from the existing reviews on the potential of chlor-alkali technology in regulating energy for environmental remediation through hydrogen-based storage. Currently, green energies are at a very high technology readiness level, but fitting the demand and production of energy is not a solved issue. Direct application in environmental treatments is inefficient, particularly in electrokinetic environment because of reversibility. Hydrogen-based energy storage shows promise, despite water management challenges in electrolyzers, especially in drought-prone regions like the Mediterranean countries. This review suggests adapting chloralkali technology from industrial to environmental contexts as a less water-demanding alternative. It also shows the adaptability of electrolyzers, contrasting it with the challenges faced by fuel cells due to chlorine's corrosive effects. It concludes that the sustainable solution proposed involves synergistic chlor-alkali electrolysis and proton exchange membrane (PEM) fuel cells using oxygen instead of chlorine, benefiting the industry affected by electricity price increase. Byproducts like chlorine and caustic soda can be repurposed for environmental or commercial purposes. |
