Energy storage caverns produce brine nobody ordered
Creating an underground cavern for hydrogen or natural gas storage means dissolving salt with water and pumping the brine out, and Europe and North America are creating caverns at a pace the energy transition has driven rather than the salt industry. The brine has to go somewhere. Where a chlor-alkali plant or evaporation facility sits nearby it becomes saleable product at very low marginal cost, and where one does not it becomes a disposal problem. Growth at 5.4% in solution mining reflects that. The commercial effect is supply arriving in specific locations for reasons entirely unrelated to salt demand.
Market Impact: Consumes 44% of total tonnage
