Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%. The recuperator improves the overall efficiency of the system.

USC team develops highly efficient catalyst system for converting CO2 to methanol; 79% yield from CO2 captured from air

Green Car Congress

In a paper published in the Journal of the American Chemical Society , they reported demonstrating for the first time that CO 2 captured from air can be directly converted to CH 3 OH in 79% yield using the new homogeneous catalytic system. They then heated the solution, converting 79% of the CO 2 into methanol. Click to enlarge.

ARA Developing Catalytic Hydrothermal Process to Convert Plant Oils Into Non-Ester Biofuels (Biohydrocarbons)

Green Car Congress

Researchers at Applied Research Associates’ (ARA) Florida Research Laboratory are developing a catalytic hydrothermolysis (CH) process to convert triglycerides (e.g., To overcome these shortcomings, a novel technical approach based on high-temperature water chemistry, known as catalytic hydrothermolysis (CH), has been proposed.

volts versus the reversible hydrogen electrode) in CO-saturated alkaline water. For the Nature study, Kanan and Li built an electrochemical cell: two electrodes placed in water saturated with carbon monoxide gas. The challenge was to find a cathode that would reduce carbon monoxide to ethanol instead of reducing water to hydrogen.
