Ethanol Production Using Corn, Switchgrass, and Wood; Biodiesel Production Using Soybean and Sunflower

  title={Ethanol Production Using Corn, Switchgrass, and Wood; Biodiesel Production Using Soybean and Sunflower},
  author={David Pimentel and Tad W. Patzek},
  journal={Natural Resources Research},
Energy outputs from ethanol produced using corn, switchgrass, and wood biomass were each less than the respective fossil energy inputs. The same was true for producing biodiesel using soybeans and sunflower, however, the energy cost for producing soybean biodiesel was only slightly negative compared with ethanol production. Findings in terms of energy outputs compared with the energy inputs were: • Ethanol production using corn grain required 29% more fossil energy than the ethanol fuel…

Ethanol production: energy, economic, and environmental losses.
The prime focus of ethanol production from corn is to replace the imported oil used in American vehicles, without expending more fossil energy in ethanol production than is produced as ethanol
Energy balances of biodiesel production from soybean and canola in Canada
This review estimates the life cycle energy balances for biodiesel produced from soybean and canola oil under Canadian conditions and outlines the three broad areas of energy inputs were crop production, oil extraction, and transesterification of the vegetable oil into biodiesel.
Biomass for Electricity and Process Heat at Ethanol Plants
Biomass can provide electricity and process heat at dry-grind ethanol plants to both reduce costs and improve the net energy value of ethanol production. Distillers dried grains with solubles
Ethanol Production Using Corn, Switchgrass and Wood; Biodiesel Production Using Soybean
In this analysis, the most recent scientific data for corn, switchgrass, and wood, for fermentation/distillation were used. All current fossil energy inputs used in corn production and for the
Comphrensive resource balance for ethanol produced from corn and sugarcane
Due to the increase in price of fossil fuels and climate change caused by Greenhouse Gas (GHG) emissions, many countries around the world are trying to produce alternative transportation fuels.
Microalgal and Terrestrial Transport Biofuels to Displace Fossil Fuels
Terrestrial transport biofuels differ in their ability to replace fossil fuels. When both the conversion of solar energy into biomass and the life cycle inputs of fossil fuels are considered, ethanol

Abstract Sub-azeotropic hydrous ethanol has been demonstrated as an effective diesel fuel replacement when used in dual-fuel compression ignition engines. Previous studies have also suggested that
Herbaceous crops with potential for biofuel production in the USA.
With suitable conversion technologies, cellulosic materials from maize, eastern gamagrass, giant reed (fibre cane), Miscanthus, reed canarygrass, sorghums, sugarcane and switchgrass might be used to produce biofuels in the USA and other non-arid, subtropical or temperate locations.
