About Magrathea Electrolytic Magnesium Process
A patent-pending process stack covering magnesium chloride dehydration and electrolysis, the step that sank earlier Western electrolytic smelters. A next-generation magnesium chloride electrolyzer has run at pilot scale in Oakland since May 2025; a 200 tonne/year Commercial Phase 1 demonstration plant in Southwest Arkansas, with TETRA Technologies, is to be commissioned in 2027.
