Our Approach

  Our process enables production of nickel-cobalt mixed hydroxide precipitate (MHP) with up to 80% less CO2 emissions and lower cost than conventional high pressure acid leaching (HPAL). We are able to achieve this feat due to our novel electrochemical membrane device that regenerates concentrated acids used in metals extraction at industry-leading energy efficiencies. Further, our low-waste plant designs will accelerate permitting within the U.S. and free-trade agreement partner countries, which makes our MHP compliant with the Inflation Reduction Act (IRA) tax credits and reduces geopolitical supply risk for our customers.
