AbstractNew molten salt chemistry allows solar thermal energy to drive calcium oxide production without any carbon dioxide emission. This is accomplished in a one pot synthesis, and at lower projected cost than the existing cement industry process, which after power production, is the largest contributor to anthropogenic greenhouse gas emissions.
The Licht research group has taken on the challenge of a comprehensive solution to climate change. We’re working towards changing today’s fossil fuel, to a renewable chemical economy, replacing the largest greenhouse gas emitters, including iron & fuel production, by new, inexpensive, solar, CO2-free, chemistries.
