Not exact matches
By turning crops such as corn, sugarcane and palm oil into biofuels — whether
ethanol, biodiesel, or something else — proponents hope to reap the benefits of the carbon soaked up as the plants grow to offset the carbon dioxide (CO2)
emitted when the resulting fuel is burned.
The carbon
emitted by burning
ethanol still piles up in the atmosphere, and remains there for decades.
Capturing the nearly pure stream of CO2
emitted from corn
ethanol refinery fermentation processes is cheaper however, and footing the bill for the added costs associated with carbon capture can be further offset
by taking advantage of the market for CO2 availed
by EOR.
Making
ethanol from corn reduces atmospheric releases of the greenhouse gas carbon dioxide because the CO2
emitted when the
ethanol burns is «canceled out»
by the carbon dioxide taken in
by the next crop of growing plants, which use it in photosynthesis.
