PyPSA-Eur-Sec builds on the electricity generation and transmission model [PyPSA-Eur](https://github.com/PyPSA/pypsa-eur) to add demand and supply for the following sectors: transport, space and water heating, biomass, industry and industrial feedstocks, agriculture, forestry and fishing. This completes the energy system and includes all greenhouse gas emitters except waste management and land use. **WARNING**: PyPSA-Eur-Sec is under active development and has several [limitations](https://pypsa-eur-sec.readthedocs.io/en/latest/limitations.html) which you should understand before using the model. The github repository [issues](https://github.com/PyPSA/pypsa-eur-sec/issues) collect known topics we are working on (please feel free to help or make suggestions). The [documentation](https://pypsa-eur-sec.readthedocs.io/) remains somewhat patchy. You can find showcases of the model's capabilities in the preprint [Benefits of a Hydrogen Network in Europe](https://arxiv.org/abs/2207.05816), a [paper in Joule with a description of the industry sector](https://arxiv.org/abs/2109.09563), or in [a 2021 presentation at EMP-E](https://nworbmot.org/energy/brown-empe.pdf). We cannot support this model if you choose to use it. Please see the [documentation](https://pypsa-eur-sec.readthedocs.io/) for installation instructions and other useful information about the snakemake workflow. This diagram gives an overview of the sectors and the links between them:  Each of these sectors is built up on the transmission network nodes from [PyPSA-Eur](https://github.com/PyPSA/pypsa-eur):  For computational reasons the model is usually clustered down to 50-200 nodes. PyPSA-Eur-Sec was initially based on the model PyPSA-Eur-Sec-30 described in the paper [Synergies of sector coupling and transmission reinforcement in a cost-optimised, highly renewable European energy system](https://arxiv.org/abs/1801.05290) (2018) but it differs by being based on the higher resolution electricity transmission model [PyPSA-Eur](https://github.com/PyPSA/pypsa-eur) rather than a one-node-per-country model, and by including biomass, industry, industrial feedstocks, aviation, shipping, better carbon management, carbon capture and usage/sequestration, and gas networks. PyPSA-Eur-Sec includes PyPSA-Eur as a [snakemake](https://snakemake.readthedocs.io/en/stable/index.html) [subworkflow](https://snakemake.readthedocs.io/en/stable/snakefiles/modularization.html#snakefiles-sub-workflows). PyPSA-Eur-Sec uses PyPSA-Eur to build the clustered transmission model along with wind, solar PV and hydroelectricity potentials and time series. Then PyPSA-Eur-Sec adds other conventional generators, storage units and the additional sectors. # Licence The code in PyPSA-Eur-Sec is released as free software under the [MIT License](https://opensource.org/licenses/MIT), see `LICENSE.txt`.
