The GREET team at Argonne National Laboratory announced a new release of the GREET fuel cycle model, used widely in fuel and vehicle lifecycle analysis. This release includes the following updates:
- New algae pathways to produce bio-oil, including the algae growth, dewatering and oil extraction stages. A separate spreadsheet for the algae process description (APD) with detailed assumptions of the key stages of the algae pathways is linked to GREET.
- New pathways for bio-oil production from palm, rapeseed, jatropha and camelina.
- New pathways for renewable gasoline and diesel production from pyrolysis of cellulosic biomass. New shale gas (SG) production pathway.
- New renewable natural gas (RNG) pathways from anaerobic digestion (AD) and conventional manure management.
- New jet fuel pathways, including operation of various classes of commercial aircrafts.
- New options to account for energy uses and emissions associated with the construction of petroleum and NG wells, and coal mines.
- Updated petroleum recovery and refining estimates.
- Updated farming assumptions for corn stover, forest residue, switchgrass, sugarcane and soybean.
