So coal ethanol is 6% less than gasoline to start. If you co-fire Powder Basin River subbituminous coal(8800 btu/pound) with 36% biomass(6000 btus per pound--corn cobbs) you end up with 77 grams per MJ(that 20% reduction). The other alternative is to bury the CO2 with CCS.Get Price

Coal is plentiful in the United States and inexpensive for its energy content. But its use comes at a cost to the environment. Learn the pros and cons of this energy source from the National Academies, advisers to the nation on science, engineering, and medicine.Get Price
Some ethanol producers burn coal and natural gas for heat sources in the fermentation process to make fuel ethanol, while some burn corn stocks or sugar cane stocks. The effect that increased ethanol use has on net CO2 emissions depends on how ethanol is made and whether or not indirect impacts on land use are included in the calculations.Get Price
Ethanol is classified as a renewable energy source; It's classified as a renewable resource because it's mainly as a consequence of conversion of energy from the sun into useful energy. The production of ethanol begins with the photosynthesis process, which enables sugarcane to thrive and later be processed into ethanol fuel.Get Price
Mar 02, 2018 · For this new process, anything from coal to natural gas to petroleum coke can be used; it's that simple. Within the industry, corn-based ethanol has been widely regarded as a disastrous failure. The agricultural lobby of course supports it, propagating what my colleague Robert Bryce has routinely called the "ethanol scam."
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.Get Price
Ethanol from coal is the ethanol produced using coal as its carbon source. The anaerobic bacterium Clostridium ljungdahlii produces ethanol and acetic acid from CO, CO 2, and H 2 in synthesis gas. Early studies with C. ljungdahlii showed that relatively high concentrations of ethanol were produced. This process involves three main steps:Get Price
