(57) An electrochemical method for producing calcium hydroxide includes dissolving a calcium precursor in a first solution in contact with a first electrode to produce Ca2+ ions, transporting the Ca2+ ions across a first membrane from the first solution into a second solution using a first electro-chemical potential, producing hydroxide ions at a second electrode, transporting the hydroxide ions across a second membrane into the second solution using a second electro-chemical potential, and precipitating calcium hydroxide from the second solution.
