Teijin developing non-platinum metal carbon alloy catalyst suited to mass production for fuel cells

Green Car Congress

Teijin Limited is developing a non-platinum carbon alloy catalyst (CAC) for the cathode oxygen reduction reaction (ORR) in polymer electrolyte fuel cells. CAC is made from polyacrylonitrile (PAN) and steel via carbonization. NEDO launched work on CAC as part of a larger fuel cell effort in FY 2008.) —Chai et al.

Researchers Develop Novel High-Performance Polymer Tin Sulfur Lithium Ion Battery

Green Car Congress

Sketch of the Sn/C/CGPE/ Li 2 S/C polymer battery. The battery is formed by a Sn/C composite anode, a PEO-based gel polymer electrolyte, and a Li 2 S/C cathode. A major hurdle is the high solubility in the organic electrolyte of the polysulfides Li 2 S x (1?x?8) They chose a tin/carbon nanocomposite, Sn/C 1:1 in weight.

EPA announces 2011 Presidential Green Chemistry Challenge Awards; green chemistry market opportunity projected to be $98.5B by 2020, about 2% of total market

Green Car Congress

Genomatica has been producing BDO at pilot scale in 3,000 liter fermentations since the first half of 2010, and is moving to production at demonstration scale in 2011. Also, the biobased BDO pathway consumes carbon dioxide (CO 2 ), resulting in a reduction of 70% in CO 2 emissions. The biggest benefits are during use.

Review of approaches to engineer microbes to produce advanced biofuels

Green Car Congress

The photosynthetic organisms will use sunlight to convert CO 2 to sugar, which the Shewanella will then convert to bio-hydrocarbons. Renewable fuels contain carbon derived from carbon dioxide. —Wackett 2010. Lawrence P Wackett (2010) Engineering microbes to produce biofuels. Earlier post.). 2010.10.010.
