Chlorine gas | Source: Wikipedia

Virtually all commercial chlorine is produced by electrolysis of aqueous sodium chloride (brine) via the chloralkali process, which simultaneously yields sodium hydroxide (caustic soda) and hydrogen gas.

Global chlorine installed capacity stood at approximately 92 million tonnes per year in 2024, growing from ~88 Mtpa in 2019, with actual market volume exceeding 100 million metric tonnes in 2023 on a consumption basis.

Chlorine is one of the most strategically important commodity chemicals, estimated to be involved — directly or as an intermediate — in the production of approximately 55–60% of all commercial chemicals by value.
