Supposedly ethanol is CO2 neutral as the volume of CO2 created by its combustion is equal to the CO2 removed from the air to produce it.
The simplicity of this thinking falls apart when you consider the CO2 generated from:
- the removal of forests from long term carbon sequestration to develop farmland
- the manufacture of the fertilizers used to grow the crops
- the emissions from the equipment used to plant, till, fertilize, and transport raw crops
- the emissions generated during fermentation
- the energy required for distillation
- the transportation of the alcohol to the sales point

Why is normal diesel not carbon neutral?
Because it's a fossil fuel. It has carbon in it.
What does it mean to say that algae fuel is carbon neutral?
Carbon neutral means that algae fuel does not affect the levels of carbon dioxide in the atmosphere. Algae takes in carbon dioxide as it grows, then, when the fuel is burnt, this same carbon dioxide is released. No increase, just exactly the same amount. This is why biofuel is so much better than fossil fuel which releases carbon that had been hidden underground for millions of years, so adding to the levels in the atmosphere.
How does going carbon neutral work?
A carbon neutral fuel is one that does not add carbon dioxide to the atmosphere. Biofuel and biomass are carbon neutral because they remove CO2 from the atmosphere during their growing season, and they release exactly the same amount of CO2 when they are burnt. So they are carbon neutral.
What is aviation turbine fuel?
it is a fuel of geometeriological ethanol
Which fuel is made by fermentation?
ethanol
Is ethanol carbon neutral or not?
No Ethanol is not carbon neutral as I am about to show you Photosynthesis: 6H2O + 6CO2 => C6H12O6 + 6O2 Fermentation: C6H12O6 => 2C2H5OH + 2CO2 Combustion: 2C2H5OH + 6O2 => 4CO2 + 6H2O by looking at this it would appear that Ethanol is carbon neutral because Photosynthesis uses 6CO2 per mole of glucose, fermentation and Combustion produce 2CO2 and 4CO2 making 6CO2 per mole of glucose but what makes ethanol not carbon neutral is that you have to burn fuel to grow and harvest the crops for fermentation, fermentation requires heat for the reaction to take place, heat comes from energy and energy comes from fossil fuels. ----====---- Only industrial scale ethanol fermentation requires additional heat. Fermentation is a biological process, in which yeast consuming sugars generates alcohol and heat. Small scale ethanol production with hand picked feedstock, is indeed Carbon Neutral.
How can ethanol reduce carbon emissions?
Ethanol is a fuel made from plants. When we burn this fuel, it does emit carbon dioxide, but of course this was originally absorbed from the atmosphere by the plants, so there is no net increase in the amount of atmospheric carbon dioxide no matter how much ethanol we use (apart from a small amount produced by generating electricity used in the production of the ethanol). A disadvantage of using ethanol for motor fuel is that its production competes with food crops.
Why is normal diesel not carbon neutral?
Because it's a fossil fuel. It has carbon in it.
What important fuel is made from sugar cane?
It is ethanol fuelSugarcane ethanol is an alcohol-based fuel produced by the fermentation of sugarcane juice and molasses.Because it is a clean, affordable and low-carbon bio-fuel, sugarcane ethanol has emerged as a leading renewable fuel for the transportation sector.
Do fuel additives work?
Yes, the fuel additives work by helping clean out the deposits left by carbon and ethanol.
How is cannabis good on the environment?
It can be used as a carbon neutral fuel.
How is ethanol and oil the same?
Ethanol and oil for fuel are both rather simple liquid hydrocarbons. Both can be used as fuel for internal combustion engines, turbines, and heating units. In many cases, equipment can be designed or retrofitted to burn either. Both burn to form carbon dioxide and water, but their carbon footprints are different. Petroleum is a fossil fuel, but ethanol is not. Petroleum predictably has a pretty specific carbon footprint, but the carbon footprint of ethanol varies according to how it is produced and is somewhat controversial. The production of ethanol could produce very little global warming gas, but it could also produce a lot.
Why is hydrogen a cleaner fuel than ethanol?
Hydrogen is a cleaner fuel than ethanol because, unlike ethanol, it does not contain hydrocarbons (which when burnt release harmful carbon dioxide and monoxide gases.). Hydrogen only produces water as a byproduct when used in combustion, so it is a cleaner fuel.
How much CO2 does a car running on ethanol fuel produce?
Assuming the fuel is 100% ethanol the reaction is: C2H5OH +3O2 --> 2CO2+3H20 or 1 mole of ethanol (46 g) creates 2 moles (44 x 2=88) of carbon dioxide The density of ethanol is 0.78 g/cm3 or .78 kg/L So the amount of carbon dioxide created by a car fueled by ethanol is about 1.56 kg/liter used. This excludes CO2 from ethanol manufacture.
What are hydrocarbons used for?
fuel and to obtain other organic compounds such as methanol, ethanol, carbon black, chloroform, formaldehyde.
What does it mean to say that algae fuel is carbon neutral?
Carbon neutral means that algae fuel does not affect the levels of carbon dioxide in the atmosphere. Algae takes in carbon dioxide as it grows, then, when the fuel is burnt, this same carbon dioxide is released. No increase, just exactly the same amount. This is why biofuel is so much better than fossil fuel which releases carbon that had been hidden underground for millions of years, so adding to the levels in the atmosphere.
What is the good things about bioethanol?
Bioethanol is blended with petrol to make a sustainable transport fuel, it's used in cosmetic and other manufacturing processes, and it creates the clean burning flame. · Bioethanol fuel is completely composed of biological products. The combustion of bio ethanol results in a clean emission: Heat, Steam and Carbon Dioxide. · Carbon dioxide is absorbed by plants. It is then processed via photosynthesis to help the plant grow. This infinite cycle of creation and combustion of energy makes bio ethanol a carbon neutral fuel source, and made by fermentation, mostly from carbohydrates produced in sugar or starch crops such as corn or sugarcane.
