Dataset and code: One-tenth of EU's biomethane potential combined with carbon capture and storage can shift the region's ammonia production to net-zero

Overview

Repository to share the data and code associated with the scientific article Istrate et al. One-tenth of EU’s biomethane potential combined with carbon capture and storage can shift the region’s ammonia production to net-zero. One Earth (2024). The repository contains data files and code to import the life cycle inventories (LCIs), reproduce the results, and generate the figures presented in the article.

The data folder includes:

• inventories.xlsx contains the LCI datasets for biomethane and ammonia production formatted for use with Brightway.
• sustainable_biomethane_potential_Europe.xlsx contains data on the sustainable biomethane potential in Europe disaggregated by feedstock and country.
• ammonia_production_europe.xlsx contains ammonia production levels in the EU in 2021.
• SA_methane leakage_for presample.xlsx contains data to perform sensitivity analysis on the methane leakage with presamples
• SA_upgrading technology_presamples.xlsx contains data to perform sensitivity analysis on upgrading technologies with presamples
• results folder within data contains csv files with the results, which are used in 05_visualization.ipynb for analysis and visualization purposes.

The notebooks folder includes:

• 01_project_setup.ipynb sets up a new Brightway project and imports the ecoinvent database.
• 02_lci.ipynb imports the LCIs and regionalize some datasets (e.g., biomethane supply based on the bimethane potential).
• 03_lcia.ipynb calculates life cycle impacts and all the additional results presented in the paper (e.g., calculation of blending ratios).
• 04_sensitivity_analysis.ipynb performs the sensitivity analysis.
• 05_visualization.ipynb imports all results and generates the figures presented in the scientific article.

The src folder contains supporting functions required to regionalize LCIs and perform the calculations.

Some of the LCI datasets in the inventories.xlsx file are partially based on data from the ecoinvent LCI database. To comply with licensing requirements, the file shared in this repository does not include these data points. If you hold a valid ecoinvent license, please contact me directly to receive the full input files containing all ecoinvent data points.
