Direct electrolytic dissolution of silicate minerals for air CO2 mitigation and carbon-negative H2 production

Posted on EPOCA: 03 Jun 2013  We experimentally demonstrate the direct coupling of silicate mineral dissolution with saline water electrolysis and H2 production to effect significant air CO2 absorption, chemical conversion, and storage in solution. In particular, we observed as much as a 105-fold increase in OH− concentration (pH increase of up to
