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. the ability to separate one gas from another.

New porous coordination polymer captures CO2, converts it to useful organic materials

Green Car Congress

The new material is a porous coordination polymer (PCP, also known as MOF; metal-organic framework), a framework consisting of zinc metal ions. However, weak gas-binding ability and/or poor sample crystallinity after guest exchange hindered the development of efficient materials for CO 2 incorporation, activation and conversion.

NSF awards $2M to Rice U collaboration to explore direct conversion of CO2 into fuels

Green Car Congress

There is still a lack of new redox-active carbon dioxide carriers for effective electrochemical carbon dioxide capture from such point sources as flue gas. We include experts in catalysts and electrolyzer design, polymer engineering, density functional theory simulations and carbon dioxide capture. —Haotian Wang.

Transform Materials plasma process converts abundant natural gas into high-value hydrogen and acetylene

Green Car Congress

Transform Materials has developed a novel and sustainable microwave plasma reactor process to convert natural gas into high-value hydrogen and acetylene, thereby opening up a new pathway for green chemical manufacturing. Oxidation of methane also introduces impurities in the product stream.

LLNL 3-D printed biocatalytic polymer turns methane to methanol at room temperature and pressure

Green Car Congress

Methane monooxygenases (MMOs), found in methanotrophic bacteria, are selective catalysts for methane activation and conversion to methanol under mild conditions; however, these enzymes are not amenable to standard enzyme immobilization approaches. The enzymes retain up to 100% activity in the polymer construct.

KIST team develops low-temperature high-performance solid-oxide fuel cell that operates on butane gas; possible EV applications

Green Car Congress

When the nickel catalyst of ceramic fuel cells is used with hydrocarbon fuels, such as methane, propane, and butane, the carbon generated during fuel conversion is deposited on the surface of nickel. This worsens seriously as the temperature lowers, leading to the failure of the cell operation.

Toshiba’s new large-scale production technology for electrolysis electrodes cuts iridium use to 1/10

Green Car Congress

Toshiba Corporation has developed large-scale production technology for electrolysis electrodes that realize high level efficiency in Power to Gas (P2G) technology while reducing the use of iridium, one of the world’s rarest precious metals, to 1/10.
