Efficient synthesis of standard fuels (gasoline, jet fuel, diesel, ethanol) from CO2, H2O, and off-peak clean energy (wind, nuclear, or geothermal) could simultaneously address grid stability, climate change, declining oil production, jobs, and trade balance. Experiments recently confirmed that the Reverse Water Gas Shift (RWGS) reaction will permit the reduction of CO2 to CO at extremely high efficiency in inexpensive adiabatic reactors. A novel low-cost catalyst recently tested achieved near theoretical CO2 conversion for H2/CO2 feed ratio of 2 at 2 bar, 916 K, with GHSV above 50,000/hr � 100 times that in most previously published RWGS experiments. More recently, we began development of a novel robust process we have denoted as CARMA  (CO2 Advanced Reforming of Methane Adiabatically). Detailed system simulations with novel subprocesses were carried out showing strong advantages in the production of the full range of liquid hydrocarbons from CO2 and a wide range of H2/CH4 feed ratios.
