Abstract
Following power generation, cement stands as the second-largest industrial source of anthropogenic greenhouse gas emissions. However, in this invention a new molten salt chemistry now enables solar thermal energy to drive to calcium oxide production, completely eliminating carbon dioxide emissions during cement production. This achievement is realized through a one-pot electrochemical synthesis method with both environmental benefits and cost efficiency. Two modes of the invention include a direct mode in which limestone is electrochemically converted to lime without CO2 emission, and the indirect mode in which the CO2 from the conventional production of lime is electrochemically converted to carbon. This invention is currently undergoing scale-up with support of the Emissions Reduction Alberta Grant IT0162473. We are looking for collaborators, joint-venturers and investors.
