Proposed CA LCFS pathways for corn starch ethanol with carbon capture and sequestration: as low as 37 gCO2e/MJ

Green Car Congress

North Dakota-based Red Trail Energy (RTE), which since 2007 has operated an ethanol production facility with annual production of about 60 million gallons per year, is proposing sequestration of CO 2 produced from starch fermentation to lower the overall carbon intensity of the fuel for the California Low Carbon Fuel Standard (LCFS).

Expansion of sugarcane crop in Brazil to areas previously occupied by crops or pastureland leads to local cooling

Green Car Congress

The study is published in the second issue of Nature Climate Change. The research team, led by Carnegie’s Scott Loarie, is the first to quantify the direct effects on the climate from sugarcane expansion in areas of existing crop and pastureland of the cerrado, in central Brazil. —Scott Loarie. —Greg Asner.

DOE Regional Partnership Begins Core Sampling for Large-Volume Carbon Sequestration Test

Green Car Congress

The Plains CO 2 Reduction (PCOR) Partnership, one of seven members of the US Department of Energy’s (DOE) Regional Carbon Sequestration Partnerships program, has begun collecting core samples from a new characterization well near Spectra Energy’s Fort Nelson natural gas processing plant in British Columbia, Canada.

Study finds global rivers and streams emitting 3x IPCC estimates of the GHG N2O

Green Car Congress

That’s three times the amount estimated by the Intergovernmental Panel on Climate Change (IPCC). Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. This multi-site experiment clearly establishes streams and rivers as important sources of nitrous oxide.

Converting Coal Power Plants to Nuclear Gains Steam

Cars That Think

On a planet aspiring to become carbon neutral, the once-stalwart coal power plant is an emerging anachronism. In neighboring Montana, state legislators recently approved a study for converting one coal plant to nuclear. It is true that, in much of the developing world, coal-fired capacity continues to grow.

DOE Regional Partnership Initiates CO2 Injection in Lignite Coal Seam

Green Car Congress

The Lignite Field Validation Test is being conducted by the Plains CO 2 Reduction (PCOR) Partnership, one of seven regional partnerships under DOE’s Regional Carbon Sequestration Partnership Program. The characterization phase (2003–2005), which defined opportunities for carbon capture and storage, has been completed.
