Background
Climate change mitigation strategies increasingly rely on enhanced mineral weathering to achieve permanent carbon dioxide removal. Processing ultramafic rocks such as olivine and serpentine requires efficient generation of acids and bases to accelerate naturally slow weathering reactions. Conventional electrochemical systems using ion exchange membranes suffer from rapid fouling and degradation when exposed to polyvalent ions present in mineral processing streams. These membrane limitations result in high capital costs, frequent maintenance, and reduced throughput. There is a need for more robust electrochemical approaches that can tolerate harsh mineral processing conditions.
Technology Overview
Researchers at MIT and Stanford have developed a membrane-free electrochemical cell that generates acid and base solutions using only a porous separator instead of expensive ion exchange membranes. The system employs bipolar gas diffusion electrodes (BPGDE) operating in mixed electrolyte solutions (NaCl + Na₂SO₄) to produce H₃O⁺/HSO₄⁻ and OH⁻ at industrially relevant concentrations. The technology achieves current densities of 140 mA/cm² with energy consumption of 0.060 kWh/mol. A periodic polarity reversal strategy (60 seconds every 5 hours) prevents electrode scaling from polyvalent precipitation.
The system was demonstrated for complete processing of olivine and serpentine minerals, producing highly reactive Mg(OH)₂ materials that carbonate 1000× faster than untreated minerals. Closed-loop operation with ~90% electrolyte recovery was validated over 25+ hour continuous runs.
