Diversity of options to reach carbon-neutrality across the entire European energy system

<strong>Sector-coupled Euro-Calliope model outputs</strong> The subdirectories found here cover cost-optimal and cost relaxation (SPORES) carbon-neutrality runs for a sector-coupled, sub-national resolution European energy system model. The underlying model to produce these results, Sector-coupled Euro-Calliope, is an extension of the power-sector only Euro-Calliope model. It incorporates all energy consuming sectors and includes a more detailed representation of transmission capacities between 98 model regions in Europe. The model runs here are based on specific Euro-Calliope v2.0 minor releases: cost-opt slack-* The models were optimised using the Calliope open energy system modelling framework, again based on different minor releases: cost-opt slack-* <code>slack-*</code> results are for cost relaxation runs, where <code>*</code> refers to the percentage relaxation from the optimal cost of the 2018 energy system. All results use the friendly data format. Data files are structured according to standardised sector-coupled Euro-Calliope output processing provided by the friendly-calliope package + additional processing to produce data relevant to nine high-level metrics (see script here).
