The Argonne National Laboratory’s Systems Assessment Center has released the suite of R&D GREET 2024 models and associated documentation. R&D GREET is a life cycle analysis (LCA) model, structured to systematically examine the 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) and other end-use sectors, and energy technology systems.

Consistent with annual updates since 1995, R&D GREET (also historically called “ANL GREET”) includes representation of new fuel pathways and updates to underlying assumptions.

Pathways represented in the tool include two major categories: A) those that have been rigorously evaluated and have high certainty; and B) those that are preliminary, which could include pathways that have not recently been evaluated; those where there is still a gap in the science or data, and/or those that are currently under internal or external peer review.

The Argonne team has provided a summary of the expansions and updates here.
