Overview This repository contains the code, input data and selected results supporting the manuscript “Navigating maritime transition pathways and energy infrastructure towards net zero”, currently submitted for review. It includes the applied energy system model ( Balmorel.zip ), the underlying input data ( data.zip ), and the results generated for the core maritime transition scenarios reported in the manuscript. This repository provides a snapshot of the model and data used in the study. The model builds on the Balmorel framework. The model code and data repositories are also available at the following locations: Model code: https://github.com/balmorelcommunity/Balmorel/tree/navigating_martime_transitions_paper-v1.0 Input data: https://github.com/balmorelcommunity/Balmorel_data/tree/navigating_martime_transitions_data-v1.0 The model and data are open source. The model is implemented in GAMS and therefore requires a GAMS licence to run. Due to its computational size, the model was solved on a high-performance computing (HPC) system using 16 cores (16 GB RAM per core), with a typical run taking approximately 24-72 hours. The results for the maritime transition scenarios are provided in .gdx format. .gdx is the standard data format used by the GAMS modelling framework to store model outputs. The files can be opened using the GAMS IDE or GDX Viewer. Instructions for running the base model Unzip Balmorel.zip . Unzip data.zip and place the data folder inside Balmorel/base/ . Run the model by executing the file Balmorel/base/model/Balmorel.gms . Instructions for running the transition scenarios from the study Unzip Scenarios.zip . Place the six scenario folders (e.g.  1-FEU-Fuel ) inside  Balmorel/ . Run each scenario by executing the relevant .gms file (e.g. Balmorel/1-FEU-Fuel/model/Balmorel.gms) . Note that any required files not explicitly defined within a scenario’s data or model folders are automatically inherited from the corresponding files in the base folder. Model results The base model results are stored in the files  Balmorel/base/model/MainResults.gdx and Balmorel/base/model/Optiflow_MainResults.gdx. Scenario results are stored in a similar way, e.g. Balmorel/1-FEU-Fuel/model/MainResults.gdx and Balmorel/1-FEU-Fuel/model/Optiflow_MainResults.gdx. MainResults.gdx contains the Balmorel energy system results, while  Optiflow_MainResults.gdx contains the results for fuel production, carbon dioxide removal and transport generated by the OptiFlow model. Output files are postprocessed and visualized in python.
