CO2 Mineralization for in situ Storage and ex situ Enhanced Metals Recovery Workshop

July 13th & 15th, 2021

The Advanced Research Projects Agency-Energy (ARPA-E) held a virtual workshop on CO2 Mineralization for in situ Storage and ex situ Enhanced Metals Recovery on July 13th & 15th, 2021. The primary purpose of this workshop was to discuss research opportunities targeting enhanced mineralization of atmospheric carbon as a tool for both sequestration and the liberation of energy relevant elements. The discussions in this workshop could help inform a potential future program in this area. You can learn more about these topics by reviewing the meeting agenda and presentations, as well as watching the pre-recorded presentations by Program Directors Douglas Wicks and Joseph King included below.
