In South Dakota, The American Coalition for Ethanol submitted feedback to the Environmental Protection Agency’s request for comment on the current scientific understanding of greenhouse gas modeling of land-based crop biofuels. ACE CEO Brian Jennings and ACE Board Director Ron Alverson contributed to the feedback after attending EPA’s workshop on biofuel GHG modeling. The comments […]
In Illinois, a research team at Argonne National Lab released its GREET 2018 update. GREET is a life-cycle analysis (LCA) tool, structured to systematically examine energy and environmental effects of a wide variety of transportation fuels and vehicle technologies in major transportation sectors (i.e., road, air, marine, and rail). There are two GREET modeling platforms; […]
In Washington, the Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model allows researchers and analysts to fully evaluate the energy and emission impacts of advanced vehicle technologies and new transportation fuels. Argonne National Laboratory recently released a new version of GREET, funded in part by the U.S. Department of Energy’s Bioenergy Technologies […]
In Illinois, the Argonne GREET team will hold two-day GREET users workshop on October 15-16, 2015, at Argonne National Laboratory to help familiarize GREET users with new developments and updates of the GREET 2015 suite of models. Sponsored by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy, the GREET (Greenhouse gases, […]
In Illinois, the Argonne National Laboratory is highlighting a new GREET fuel cycle model release (GREET1 2013) uploaded to the GREET web site. This release includes the following updates: New marine fuel pathways and commercial vessel operations: New sorghum ethanol pathways; New Tallow pathway; Electric power sector technology shares, efficiencies and emission factors by technology […]
In Illinois, researchers from Argonne National Laboratory have identified a better way to analyze GHG emissions in algae using GREET, a tool for the life-cycle analysis of energy use and emissions in transportation systems. The baseline scenario produced 55 400 g CO2 equivalent per million BTU of biodiesel compared to 101 000 g for low-sulfur petroleum diesel. The […]
