A bio-ethanol fireplace with artificial wood logs. An ethanol fireplace (also bio-ethanol fireplace, bio fireplace), is a type of fireplace which burns ethanol fuel. They are often installed without a chimney. Ethanol for these fires is often marketed as bioethanol (ethanol produced from biomass). [clarification needed]
[1] [2] Conversion of biomass to liquid fuels is preferred as an alternative to the extraction of fossil fuels because biomass removes carbon dioxide from the atmosphere as it grows through photosynthesis. When combusted, this carbon is re-released into the atmosphere, closing the carbon cycle and making biofuels carbon neutral under some ...
The bioconversion of biomass to mixed alcohol fuels can be accomplished using the MixAlco process. Through bioconversion of biomass to a mixed alcohol fuel , more energy from the biomass will end up as liquid fuels than in converting biomass to ethanol by yeast fermentation.
The carbon dioxide that plants absorb as they grow offsets some of the carbon dioxide emitted when ethanol made from them is burned, so cellulosic ethanol fuel has the potential to have a lower carbon footprint than fossil fuels. Interest in cellulosic ethanol is driven by its potential to replace ethanol made from corn or sugarcane. Since ...
As of 2006, mandates for blending bioethanol into vehicle fuels had been enacted in at least 36 states/provinces and 17 countries at the national level, with most mandates requiring a blend of 10 to 15% ethanol with gasoline. [4] One measure of alternative fuels in the U.S. is the "gasoline-equivalent gallon" (GEG).
By December 2011 Brazil had a fleet of 14.8 million flex-fuel automobiles and light trucks [8] [9] and 1.5 million flex-fuel motorcycles [10] [11] [12] that regularly use neat ethanol fuel (known as E100). Bioethanol is a form of renewable energy that can be produced from agricultural feedstocks.
