GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

Stuart Licht have demonstrated the first facile high-yield, low-energy synthesis of macroscopic length carbon nanotubes (CNTs)—carbon nanotube wool—from CO 2 using molten carbonate electrolysis ( earlier post ). The process is constrained by the (low) cost of electricity. —Johnson et al.

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

Methane derived from CO 2 and renewable H 2 sources is an attractive fuel, and it has great potential as a renewable hydrogen carrier as an environmentally responsible carbon capture and utilization approach. 2021), “Integrated Capture and Conversion of CO2 to Methane using a Water-lean, Post-Combustion CO2 Capture Solvent.”

Novel sorbent achieves 90% carbon capture in DOE-sponsored test

Green Car Congress

The successful bench-scale test of a novel carbon dioxide capturing sorbent promises to further advance the process as a possible technological option for reducing CO 2 emissions from coal-fired power plants. SRI’s carbon capture process, which includes both the sorbent and unique process design, looks promising for future applications.

EPFL team develops low-cost catalyst for splitting CO2

Green Car Congress

EPFL scientists have developed an Earth-abundant and low-cost catalytic system for splitting CO 2 into CO and oxygen—an important step towards achieving the conversion of renewable energy into hydrocarbon fuels. Using only Earth-abundant materials to catalyze both reactions, this design keeps the cost of the system low.

GWU team develops low-cost, high-yield one-pot synthesis of carbon nanofibers from atmospheric CO2

Green Car Congress

A team led by Dr. Stuart Licht at The George Washington University in Washington, DC has developed a low-cost, high-yield and scalable process for the electrolytic conversion of atmospheric CO 2 dissolved in molten carbonates into carbon nanofibers (CNFs.) Atmospheric air is added to an electrolytic cell.

GWU team suggests C2CNT carbon nanotube composites could amplify reduction of GHG emissions

Green Car Congress

Stuart Licht reports that the addition of carbon nanotubes (CNTs) produced from CO 2 by low-energy C2CNT (CO 2 to CNT) molten electrolysis ( earlier post ) to materials such as concrete or steel not only forms composites with significantly better properties, but amplifies the reduction of CO 2. A) Carbon mitigation with CNT-cement. (B)

GWU team develops cost-effective solar process to produce lime for cement without CO2 emission

Green Car Congress

Conventional thermal decomposition production of lime (left) versus STEP direct solar conversion of calcium carbonate to calcium oxide (right). Surprisingly, this situation is reversed at high temperatures in molten carbonates, which allows the endothermic, electrolytic one pot synthesis, and precipitation of CaO. Click to enlarge.
