Abstract Standard (RFS) are on LCA basis Renewable fuel (D6) – 20% GHG reduction - Plants existing before 2008 - Corn ethanol - Corn starch butanol - Sorghum ethanol w/NG process energy Compliance of fuel with RFS determined by EPA based on lifecycle greenhouse gas emissions Use of suite of models, including GREET for LCA Corn ethanol’s contribution to this total is explicitly limited, however, since the statute prohibits the use of more than 15 billion gallons of corn ethanol for RFS compliance. The industry already has 15 billion gallons of corn ethanol capacity 42 and can actually produce beyond that level with its existing plants. 43 This leaves little room for corn ethanol growth before hitting the RFS The Brazilian Corn Ethanol Union (UNEM) estimates that the sector will produce about 2.5 billion liters of corn-based ethanol in market year 2020/21.

Developing Life Cycle Sustainability Assessment

2017-08-29 · Because corn used for ethanol production is counted separately from wet mill corn use in the ERS data, it is important to calculate the quantity of corn used by wet mills to produce all goods except ethanol. The bushels of corn required to produce the quantities of ethanol are calculated for each wet mill.

High‐purity CO 2 generated from the fermentation process is used as the feedstock for additional ethanol production through a gas fermentation process plus an electrochemical reduction process (Fig. 1).

Harmonization of corn stover ethanol production Allocation Issues in LCA Methodology: A Case Study of Corn Stover-Based Fuel Ethanol Larry Santos AbstractFacing the threat of oil depletion and climate change, a shift from fossil resources to renewables is ongoing to secure long-term low carbon energy supplies. to the corn cultivation, and fossil fuels consumption. Keywords: life cycle assessment (LCA), bio-ethanol, CO2 balance 1 INTRODUCTION Bioethanol derived from biomass is often considered a significant contributor for a sustainable transportation fuel.

2014-01-30 · The carbon intensity (CI) of corn ethanol—i.e., the greenhouse gas emissions produced via the production of a volume of the fuel—is declining, while the average CI of gasoline produced from petroleum sources is gradually increasing, according to a recent report prepared by Life Cycle Associates, LLC for the Renewable Fuels Association (RFA). Selection of corn ethanol plant type affects LCA results Dry mill (nearly 90% of fleet) Wet mill Process fuel –Natural gas –Coal –Biomass Corn oil extraction Integrated production of corn and stover ethanol 11 The life cycles of the fuels include gasoline production, corn and stover agriculture, cellulosic ethanol production, blending ethanol with gasoline to produce E10 (10% of ethanol) and E85 (85% of ethanol), and finally the use of gasoline, E10, E85, and ethanol.
