**Gas Transmission Network**
|
|
|
|
|
|
|
|
|
|
* New rule ``retrieve_gas_infrastructure_data`` that downloads and extracts the
|
|
|
|
|
SciGRID_gas `IGGIELGN <https://zenodo.org/record/4767098>`_ dataset from zenodo.
|
|
|
|
|
It includes data on the transmission routes, pipe diameters, capacities, pressure,
|
|
|
|
|
and whether the pipeline is bidirectional and carries H-Gas or L-Gas.

|
|
|
|
|
(including planned projects from gem.wiki), pipeline entry capacities and
|
|
|
|

|
|
|
|
|
|
|
|
* Add option to aggregate network temporally using representative snapshots or segments (with tsam package)
|
|
|
|
|
|
|
|
|
|
* Add option for biomass boilers (wood pellets) for decentral heating
|
|
|
|
|
|
|
|
|
|
* Add option for BioSNG (methane from biomass) with and without CC

|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
* Units are assigned to the buses. These only provide a better understanding. The specifications of the units are not taken into account in the optimisation, which means that no automatic conversion of units takes place.
|
|
|
|
|
|
|
|
|
|
* Option ``retrieve_sector_databundle`` to automatically retrieve and extract data bundle.
|
|
|
|
|
|
|
|
|
|
* Add option to use waste heat of electrolysis in district heating networks (``use_electrolysis_waste_heat``).
|
|
|
|
|
|
|
|
|
|
* Add regionalised hydrogen salt cavern storage potentials from `Technical Potential of Salt Caverns for Hydrogen Storage in Europe <https://doi.org/10.20944/preprints201910.0187.v1>`_.
|
|
|
|
|
|
|
|
|
|
* Add option to sweep the global CO2 sequestration potentials with keyword ``seq200`` in the ``{sector_opts}`` wildcard (for limit of 200 Mt CO2).
|
|
|
|
|
|
|
|
|
|
* Add option to resolve ammonia as separate energy carrier with Haber-Bosch
|
|
|
|
|
synthesis, ammonia cracking, storage and industrial demand. The ammonia
|
|
|
|
|
carrier can be nodally resolved or copperplated across Europe. This feature is
|
|
|
|
|
controlled by ``sector: ammonia:``.
|
|
|
|
|
|
|
|
|
|
* Add methanol as energy carrier, methanolisation as process, and option for methanol demand in shipping sector.
|
|
|
|
|
|
|
|
|
|
* Updated `data bundle <https://zenodo.org/record/5824485/files/pypsa-eur-sec-data-bundle.tar.gz>`_ that includes the hydrogan salt cavern storage potentials.
|
|
|
|
|
|
|
|
|
|
* Updated and extended documentation in <https://pypsa-eur-sec.readthedocs.io/en/latest/>
|
|
|
|
|
|
|
|
|
|
* Shipping demand now defaults to (synthetic) oil rather than liquefied hydrogen until 2050.
|
|
|
|
|
|
|
|
|
|
* Improved network plots including better legends, hydrogen retrofitting network display, and change to EqualEarth projection.
|
|
|
|
|
|
|
|

agriculture machinery (``agriculture_machinery_oil_share``).
|
|
|
|
|
**Carbon Management and Biomass**
|
|
|
|
|
|
|
|
|
|
* Add option to spatially resolve carrier representing stored carbon dioxide
|
|
|
|
|
(``co2_spatial``). This allows for more detailed modelling of CCUTS, e.g.
|
|
|
|
|
regarding the capturing of industrial process emissions, usage as feedstock
|
|
|
|
|
for electrofuels, transport of carbon dioxide, and geological sequestration sites.
|
|
|
|
|
|
|
|
|
|
* Add option for planning a new carbon dioxide network (``co2network``).

|
|
|
Potential of Salt Caverns for Hydrogen Storage in Europe
|
|
|
|
|
<https://doi.org/10.20944/preprints201910.0187.v1>`_. This data is compiled in
|
|
|
|
|
a new rule ``build_salt_cavern_potentials``.
|
|
|
|
|
|
|
|
|
|
* Add option to resolve ammonia as separate energy carrier with Haber-Bosch
|
|
|
|
|
synthesis, ammonia cracking, storage and industrial demand. The ammonia
|
|
|
|
|
carrier can be nodally resolved or copperplated across Europe (see
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
* Add methanol as energy carrier, methanolisation as process, and option for
|
|
|
|
|
methanol demand in shipping sector.
|
|
|
|
|
|
|
|
|
|
* Shipping demand now defaults to methanol rather than liquefied hydrogen
|
|
|
|
|
until 2050.
|
|
|
|
|
|
|
|
|
|
* Demand for liquid hydrogen in international shipping is now geographically
|
|
|
|
|
distributed by port trade volumes in a new rule ``build_shipping_demand``
|
|
|
|
|
using data from the `World Bank Data Catalogue
|
|
|
|
|
<https://datacatalog.worldbank.org/search/dataset/0038118/Global---International-Ports>`_.
|
|
|
|
|
Domestic shipping remains distributed by population.
|
|
|
|
|
|
|
|
|
|
* Add option to aggregate network temporally using representative snapshots or
|
|
|
|
|
segments (with `tsam <https://github.com/FZJ-IEK3-VSA/tsam>`_).
|
|
|
|
|
|
|
|
|
|
* Add option for minimum part load for Fischer-Tropsch plants (default: 90%) and
|
|
|
|
|
methanolisation plants (default: 50%).
|
|
|
|
|
|
|
|
|
|
* Add option to use waste heat of electrolysis in district heating networks
|
|
|
|
|
(``use_electrolysis_waste_heat``).
|
|
|
|
|
|
|
|
|
|
* Add option for coal CHPs with carbon capture (see ``coal_cc``).
|
|
|
|
|
|
|
|
|
|
* In overnight optimisation, it is now possible to specify a year for the
|
|
|
|
|
technology cost projections separate from the planning horizon.
|
|
|
|
|
|
|
|
|
|
* New config options for changing energy demands in aviation
|
|
|
|
|
(``aviation_demand_factor``) and HVC industry (``HVC_demand_factor``), as well
|
|
|
|
|
as explicit ICE shares for land transport (``land_transport_ice_share``) and
|
|
|
|
|
agriculture machinery (``agriculture_machinery_oil_share``).
|
|
|
|
|
|
|
|
|
|
* It is now possible to merge residential and services heat buses to reduce the
|
|
|
|
|
problem size (see ``cluster_heat_nodes``).
|
|
|
|
|
|
|
|
|
|
* Added option to tweak (almost) any configuration parameter through the
|
|
|
|
|
``{sector_opts}`` wildcard. The regional_co2_sequestration_potential is
|
|
|
|
|
triggered by the prefix ``CF+`` after which it is possible to pipe to any
|
|
|
|
|
setting that does not contain underscores (``_``). Example:
|
|
|
|
|
``CF+sector+v2g+false`` disables vehicle-to-grid flexibility.
|
|
|
|
|
|
|
|
|
|
* Option ``retrieve_sector_databundle`` to automatically retrieve and extract
|
|
|
|
|
data bundle.
|
|
|
|
|
|
|
|
|
|
* Removed the need to clone ``technology-data`` repository in a parallel
|
|
|
|
|
directory. The new approach automatically retrieves the technology data from
|
|
|
|
|
remote in the rule ``retrieve_cost_data``.
|
|
|
|
|
|
|
|
|
|
* Improved network plots including better legends, hydrogen retrofitting network
|
|
|
|
|
display, and change to EqualEarth projection. A new color scheme for
|
|
|
|
|
technologies was also introduced.
|
|
|
|
|
|
|
|
|
|
* Add two new rules ``build_transport_demand`` and
|
|
|
|
|
``build_population_weighted_energy_totals`` using code previously contained in
|
|
|
|
|
``prepare_sector_network``.
|
|
|
|
|
|
|
|
|
|
* Rules that convert weather data with ``atlite`` now largely run separately for
|
|
|
|
|
categories residential, rural and total.
|
|
|
|
|
|
|
|
|
|
* Units are assigned to the buses. These only provide a better understanding.
|
|
|
|
|
The specifications of the units are not taken into account in the
|
|
|
|
|
optimisation, which means that no automatic conversion of units takes place.
|
|
|
|
|
|
|
|
|
|
* Configuration file and wildcards are now stored under ``n.meta`` in every
|
|
|
|
|
PyPSA network.
|
|
|
|
|
|
|
|
|
|
* Updated `data bundle
|
|
|
|
|
<https://zenodo.org/record/5824485/files/pypsa-eur-sec-data-bundle.tar.gz>`_
|
|
|
|
|
that includes the hydrogan salt cavern storage potentials.
|
|
|
|
|
|
|
|
|
|
* Updated and extended documentation in
|
|
|
|
|
<https://pypsa-eur-sec.readthedocs.io/en/latest/>
|
|
|
|
|
|
|
|
|
|
* Added new rule ``copy_conda_env`` that exports a list of packages with which
|
|
|
|
|
the workflow was executed.
|
|
|
|
|
|
|
|
|
|
* Add basic continuous integration using Github Actions.
|
|
|
|
|
|
|
|
|
|
* Add basic ``rsync`` setup.

|
|
|
|
