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.

Picture4A new fundemental solar process has been introduced. This STEP process efficiently removes carbon from the atmosphere and generates the staples needed by society, ranging from fuels, to metals, bleach and construction materials, at high solar efficiency and without carbon dioxide generation. By using the full spectrum of sunlight, STEP captures more solar energy than the most efficient solar cell or photoelectrochemical processes.

Sunlight converts CO2 to carbon nanofibers (shown) and drives new CO2-free syntheses for iron, cement and fertilizer.
The Licht group’s C2CNT process CO2 to carbon nanotubes and drives new CO2-free solar syntheses for iron, cement and fertilizer.

                    

In the field of energy storage for devices ranging from EVs to consumer electronics and peak power storage, we’re pioneering the study of new multiple electron (per molecule) storage processes, to learn to create batteries and fuel cells with greater storage capacity than gasoline.

En route to new renewable energy pathways, our explorations range from water thermodynamics to new environmental methodologies & from quantum mechanics to H2, halide, chalcogenide & transition metal chemistry.
