On the use of chlor-alkali technology to power environmental electrochemical treatment technologies

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 energ...
