PROFILE

Jakob Duerrwaechter

Worked on emissions modeling and energy systems analysis across the remindmodel/remind and pik-piam/mrremind repositories, focusing on improving data reliability and model maintainability. Delivered features such as refactored feedstock quantity formulation for the chemicals sector and streamlined carbon emissions modeling, using R and GAMS to enhance emissions accounting accuracy. Addressed data inconsistencies by stabilizing industry subsector imports and updating dependencies, while performing code cleanup and documentation improvements to reduce maintenance overhead. Managed configuration and package dependencies with YAML and Shell scripting, ensuring compatibility and smoother releases. The work strengthened cross-repository integration and improved the foundation for future enhancements.

Apr 1, 2025

Monthly summary for 2025-04 focusing on key feature delivery in remindmodel/remind. Emissions accounting accuracy improvement for the chemicals sector was implemented via a refactor of feedstock quantity formulation to ensure equal shares across Feedstock (FE) types and by updating calculations for chemical sector feedstock limits and balances to reflect the proportion of fossil, biomass, and synfuel inputs. This change improves emissions accounting by better representing carbon bound in output materials and sets the groundwork for more trustworthy metrics.
