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

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure). Lopez, J.S.,

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

Green Car Congress

This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity. The process is constrained by the (low) cost of electricity. Schematic representation of an ocean-based solar thermal and photovoltaic field to drive both water purification and C2CNT splitting of CO 2 to useful products.

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 suggests C2CNT carbon nanotube composites could amplify reduction of GHG emissions

Green Car Congress

The C2CNT production is achieved at a fraction of the current cost of manufacturing nanotubes and results in a cost of carbon savings in the materials production significantly below the current cost of carbon mitigation. Approximately 4 tonnes of CO 2 is absorbed in this process for every tonne of carbon nanotubes produced.

Biofeedstock company Proterro hits milestones with bioreactor for sucrose produced via cyanobacteria; commissioning pilot plant

Green Car Congress

Using CO~2, sunlight and water, Proterro lowers the cost of sugar production to around $0.05/lb This process yields a fermentation-ready sucrose stream, rather than a mixture of sugars, allowing simple, low-cost downstream processing. —Kef Kasdin.

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

Stuart Licht ( earlier post ) have developed a new process that transforms CO 2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes). This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity.

DOE to award up to $15M for projects to improve reliability of solid oxide fuel cells

Green Car Congress

The purpose of the FOA is to advance the reliability, robustness and endurance of low-cost solid oxide fuel cell (SOFC) technology suitable for ultimate deployment in equal to or greater than (?) 97% carbon dioxide (CO2) capture. SOFCs with an average stack operating temperature of 600 °C) and below are not of interest.
