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). Heldebrant, D.,

BMW i Ventures invests in Prometheus Fuels; CO2 air-capture and conversion to carbon-neutral gasoline

Green Car Congress

BMW i Ventures has invested in Prometheus Fuels ( earlier post ), a company removing CO 2 from the air and turning it into zero-net carbon gasoline that it will sell at gas stations, at a price that competes with fossil fuels, starting as early as this year. Aqueous CO 2 electrolysis with base-metal catalysts. 2020.01.002.

Montauk Renewables signs LOI with European Energy to provide CO2 for e-methanol production in Texas

Green Car Congress

The planned delivery would prevent biogenic CO 2 from entering the atmosphere and put it to beneficial use, creating a new fixed-price commodity revenue stream for Montauk. The LOI between Montauk and EE North America assists Montauk in synchronizing capital commitment timing at its Texas facilities with EE North America’s project.

U of I study: synthetic fuels via CO2 conversion and FT not currently economically & environmentally competitive

Green Car Congress

However, they noted, that with the right combination of high FT fuel yield and low electricity and hydrogen price, the synthetic fuel system could produce fuels at a cost range similar to the reference year 2014 petroleum-based fuel prices. The well-to-gate energy efficiency varies from 41 to 65%. Stubbins, and Paul J. 6b00665.

New inexpensive catalyst for conversion of CO2 to CO could help with storage of renewable energy

Green Car Congress

Moreover, Bi is a byproduct of Pb, Cu, and Sn refining, and has few significant commercial applications, resulting in the price of Bi being low and stable. As such, development of Bi-based cathodes for conversion of CO 2 to CO would represent an important development for the fields of CO 2 electrocatalysis and renewable energy conversion.

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

Green Car Congress

The resulting CNT wool is of length suitable for weaving into carbon composites and textiles and is highly conductive; the calculated cost to produce the CNTs is approximately $660 per ton, compared to the current $100,000+ per ton price range of CNTs. A paper on the work is published in the journal Materials Today Energy. Johnson et al.
