New polymer membrane efficiently removes carbon dioxide from mixed gases; high permeability and selectivity

Green Car Congress

A team of researchers from North Carolina State University, SINTEF in Norway and the Norwegian University of Science and Technology, has developed a polymer membrane technology that removes carbon dioxide from mixed gases with both high permeability and high selectivity. A paper on their work is published in the journal Science.

New system for more efficient CO2 electrolysis to hydrocarbon products

Green Car Congress

The researchers combined a copper electrocatalyst with an ionomer [polymers that conduct ions and water] assembly that intersperses sulfonate-lined paths for the H 2 O with fluorocarbon channels for the CO 2. 2020) “CO2 electrolysis to multicarbon products at activities greater than 1 A cm -2.” —García de Arquer et al.

Twelve and LanzaTech successfully convert CO2 to ethanol

Green Car Congress

Polypropylene is a major polymer used in key applications, including medical devices like syringes and IV bags, automotive, furniture, textiles, and other durable products. This approach is highly scalable and could ultimately produce ethanol at an industrial scale, while simultaneously eliminating CO 2 emissions.

MIT researchers propose mechanism for overcoming bottleneck in electroreduction of CO2

Green Car Congress

The findings could spur progress on developing a variety of materials and designs for electrochemical carbon dioxide conversion systems. There are several ways to do such conversions, including electrochemical, thermocatalytic, photothermal, or photochemical processes—each with their own problems or challenges.

Twelve produces first batch of E-Jet fuel from CO2 electrolysis; partnership with USAF; electrifying fuel, not planes

Green Car Congress

Twelve’s jet fuel, produced using its carbon transformation technology in partnership with Fischer-Tropsch conversion experts Emerging Fuels Technology ( earlier post ), is a fossil-free fuel that offers a drop-in replacement for petrochemical-based alternatives without any changes to existing plane design or commercial regulations.

New one-pot conversion of CO2 to polycarbonate copolymers

Green Car Congress

Researchers at Texas A&M have developed a two-step, one-pot conversion of CO 2 and epoxides (highly reactive compounds with a three-membered ring made of two carbon atoms and one oxygen atom) to polycarbonate block copolymers that contain both water-soluble and hydrophobic regions and can aggregate into nanoparticles or micelles.
