Georgia Tech team develops conversion-type iron-fluoride Li battery cathode with solid polymer electrolyte

Green Car Congress

Researchers at Georgia Tech have developed a promising new conversion-type cathode and electrolyte system that replaces expensive metals and traditional liquid electrolyte with lower cost transition metal fluorides and a solid polymer electrolyte. A paper on their work is published in the journal Nature Materials.

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

Green Car Congress

Currently, liquid products generated by electrochemical carbon dioxide reduction-reaction systems have been mixed with liquid electrolytes/soluble solutes, which requires energy- and cost-intensive separation processes to recover pure liquid fuel solutions. To address these challenges, our project is interdisciplinary. —Haotian Wang.

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. Blanchette et al.

Researchers develop thin-layer artificial biofilm technology for green ethylene production

Green Car Congress

PCC 6803 cells holding ethylene forming enzyme (Efe) from Pseudomonas syringae are entrapped within a natural polymer matrix, thus forming the thin-layer biocatalytic structure. 2 ethylene at 1.54% light to ethylene conversion efficiency. PCC 6803 mutant produced ethylene for up to 38 days, yielding 822 mL m ?2

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. The low cost of porous melamine means that the material could be deployed widely. —Mao et al.

Corvus Energy’s marine lithium polymer battery pack used in Europe’s first hybrid tugboat

Green Car Congress

Lithium polymer battery packs from Corvus Energy were recently installed in Europe’s first hybrid tugboat, the RotorTug RT Adriaan of KOTUG, an international maritime service provider headquartered in The Netherlands. The conversion features Corvus’ AT6500 48 volt lithium polymer battery packs. Corvus uses Dow Kokam cells.
