R&D GREET Marine Module 2024

The GREET team at the Life Cycle Analysis and Technology Assessment Department of Argonne National Laboratory is pleased to announce the release of the R&D GREET Marine Module 2024.

The Life Cycle Analysis and Technology Assessment Department at Argonne National Laboratory has developed an interactive standalone marine module (R&D GREET Marine Module 2024) to have a consistent platform for life cycle analysis of marine fuels. It is intended to evaluate the environmental impact of various marine fuel production pathways including both fossil and non-fossil marine fuels. For easy access, this module uses Microsoft Excel with Visual Basic for Applications (VBA) to enable an interactive user interface.

In this release, we have added the background datasets for marine fuels with the most current R&D GREET version – R&D GREET 2024 Rev1. We made the R&D GREET Marine Module dynamically interact with the R&D GREET fuel cycle model (R&D GREET1) by directly reading upstream life cycle energy uses and emissions for key inputs to various stages in various marine fuel production pathways. The dynamic version enables changing the default input parameters of the R&D GREET1 model to user defined inputs. The connection to the R&D GREET1 model in the background is automatic and the results are illustrated in the interactive R&D GREET Marine Module Excel file.

For detailed instructions on how to use the module, please refer to the R&D GREET Marine Module Introduction and Instruction document.

The R&D GREET Marine Module 2024 is developed with Microsoft Office 365. For best performance, we highly recommend using Microsoft Office 365 to run the module.
