Biofuels from crop residue can reduce soil carbon and increase CO<sub>2</sub> emissions

Removal of corn residue for biofuels can decrease soil organic carbon1,2 (SOC) and increase CO2 emissions3 because residue C in biofuels is oxidized to CO2 at a faster rate than when added to soil.4,5 Net CO2 emissions from residue removal are not adequately characterized in biofuel life cycle assessment (LCA).6–8 Here we used a model to estimate CO2 emissions from corn residue removal across t...

Indirect emissions from biofuels: how important?

A global biofuels program will lead to intense pressures on land supply and can increase greenhouse gas emissions from land-use changes. Using linked economic and terrestrial biogeochemistry models, we examined direct and indirect effects of possible land-use changes from an expanded global cellulosic bioenergy program on greenhouse gas emissions over the 21st century. Our model predicts that i...

Soil Greenhouse Gas Emissions in the Life Cycle Assessment of Cellulosic Ethanol From Crop Residue

Concerns about climate change and the increasing cost of fossil fuels have led to interest in the development of renewable biofuel pathways for reducing greenhouse gas (GHG) emissions. The use of corn residue as a potential source of biomass feedstock for cellulosic ethanol production has been favored as cost effective. Previous research has shown that crop residue removal can cause a loss of s...

Harvesting Energy from CO2 Emissions

When two fluids with different compositions are mixed, mixing energy is released. This holds true for both liquids and gases, though in the case of gases, no technology is yet available to harvest this energy source. Mixing the CO2 in combustion gases with air represents a source of energy with a total annual worldwide capacity of 1570 TWh. To harvest the mixing energy from CO2-containing gas e...

A STELLA Model to Estimate Soil CO2 Emissions from a Short-Rotation Woody Crop

The potential for climatic factors as well as soil–plant–climate interactions to change as a result of rising levels of atmospheric CO2 concentration is an issue of increasing international environmental concern. Agricultural and forest practices and managements may be important contributors to mitigating elevated atmospheric CO2 concentrations. A computer model was developed using the Structur...
