STEP- Developing of a Mobile Outdoor System for the Solar Thermal Electrochemical Process for Green Cement Production

Solar Thermal Electrochemical Process (STEP) for green cement production is a unique process that allows for the electrochemical conversion of calcium carbonate into calcium oxide in a molten carbonate system that releases no carbon dioxide into the atmosphere. 1 STEP cement production is one of a family of new processes of efficient solar synthesis. Utilizing a combination of solar thermal energy for heating processes and other renewable electric energy sources for electronic charge, STEP is able to electrochemically synthesize a variety of societal staples ranging from fuels and metal production (including iron and magnesium), carbon dioxide splitting, and wastewater treatment. Each process offers a unique chemistry, but all processes use the full solar spectrum to lower and drive the energy of endothermic electrochemical reactions. High temperature molten salt electrolytes offer significant benefits to STEP of high reactant concentration and facile derivation of a wide range of useful gas, liquid and solid products. The effective chemistry of STEP in an increasing range of electrolytes and in the presence of impurities has been demonstrated.
