The GREET team at Argonne National Laboratory has released a new release of the GREET fuel cycle model (GREET 1 2012 rev2) as well as a GREET (Beta) featuring a fully graphical toolbox to perform life cycle analysis simulations of alternative transportation fuels and vehicle technologies in a matter of a few clicks.
The Greenhouse gases, Regulated Emissions and Energy use in Transportation (GREET) full life-cycle model is used to evaluate and compare the environmental impacts of new transportation fuels and advanced vehicle technologies. The rev2 release includes the following updates:
- Added hydrothermal liquefaction of algae;
- Added wastewater sludge-based renewable natural gas;
- Updated sugarcane ethanol pathways;
- Replaced farmed trees farming with willow and popular farming;
- Updated electricity generation mixes, shale gas shares and oil sand shares;
- Added navigation menus to enhance the user experience;
- Added energy functional units to the “Results” worksheet; and
- Adjusted lipid and moisture contents of oil seeds and their impact on oil and co-product yields.
The GREET (Beta) features a new user-friendly platform. The new integrated design is based on the GREET database layered with algorithms and a graphical interface, with the intention of making it a powerful and flexible tool. The new intuitive graphical interface allows the user to create new pathways from the available database using simple drag-and-drop operations.
