Conversion of cropland from corn to perennial biofuel grasses for ethanol production could transition the central US from a net source to a net sink for GHGs

Green Car Congress

The study evaluated the potential impact of using biofuel grass species instead of corn as a method of producing ethanol within the US Corn Belt, and is published in the journal Frontiers in Ecology and the Environment. —Davis et al. Frontiers in Ecology and the Environment doi: 10.1890/110003. —William Parton.

Honda and Ford separately launching smart home demos

Green Car Congress

The site is on the campus of the University of California, Davis; the building process will be documented and shared through the Honda Smart Home US website. It is expected to produce more energy than it consumes, using less than half of the energy of a similarly sized new home in the Davis area for heating, cooling, and lighting.

NREL modifies organism to produce ethylene via photosynthesis: alternative to fossil-fuel based ethylene for chemicals and transportation fuels

Green Car Congress

This study suggests that Synechocystis , expressing the modified efe gene, has potential to be an efficient biological catalyst for the uptake and conversion of CO 2 to ethylene. Conversely, the process recycles carbon dioxide, a greenhouse gas, since the organism utilizes the gas as part of its metabolic cycle. Energy Environ.

ZeaChem signs contract to develop advanced drop-in biofuels beyond cellulosic ethanol

Green Car Congress

Acetogens have several advantages to yeast: they convert all xylose (C 5 ) and glucose (C 6 ) sugars and tolerate all breakdown products of biomass; they operate in harsh environments; and they produce no CO 2 as a by-product. ZeaChem Inc.,

USDA and DOE award $12.2M to 10 research projects to accelerate bioenergy crop production and spur economic impact

Green Car Congress

Overall, the USDA and DOE projects are designed to improve special crops to be grown for biofuels—including selected trees and grasses—by increasing their yield, quality and ability to adapt to extreme environments.
