Current estimates, which I documented in the afore - mentioned article, put the cost of a biomass gasification plant at about 7 times the per barrel cost of a conventional oil refinery or
grain ethanol plant, and double the costs of a coal - to - liquids plant.

Not drying distillers
grains is feasible only if large beef feedlots or dairies are located near the
ethanol plants....
The key factors determining carbon emissions for corn - based
ethanol are (1) whether coal or natural gas is used to power the
ethanol plant, (2) whether distillers
grains are dried or sold wet, and (3) whether expansion of corn acreage comes mainly from reduced acreage of lower - value crops or if idled land is brought into production.
For example, a farmer in northern Iowa could
plant an acre in corn that yields enough
grain to produce roughly $ 1,000 worth of fuel - grade
ethanol per year, or he could use that same acre to site a turbine producing $ 300,000 worth of electricity each year.
The stickiest question about
ethanol is this: Does making alcohol from
grain or
plant waste really create any new energy?
For example, with such genetically - engineered biocatalysts it is not only
grains of corn but corn cobs and most of the rest of the corn
plant that may be used to make
ethanol.
Although human beings have been producing
ethanol,
grain alcohol, from sugar and starch for millennia, it is only in recent years that the genetic engineering of biocatalysts has made possible such production from the hemicellulose and cellulose that constitute the substantial majority of the material in most
plants.
In 2002, twelve Minnesota
ethanol plants were fined by US Department of Justice for violation of Clean Air Act and each agreed to spend more than $ 2 million for installation of control devices to reduce air pollutants, which were caused primarily by the manufacturing of Dry Distiller

Led by David Tilman, a biology professor at the University of Minnesota, the research shows that «mixtures of native perennial grasses and other flowering
plants provide more usable energy per acre than corn
grain ethanol or soybean biodiesel and are far better for the environment,» according to a release from the University of Minnesota.
