Information about demands in the mobility sector. | ||
Motorized individual travel | ||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
|
||
The electricity demand data of motorized individual travel (MIT) for both the eGon2035 | ||
and eGon100RE scenario is set up | ||
in the :py:class:`MotorizedIndividualTravel<egon.data.datasets.emobility.motorized_individual_travel.MotorizedIndividualTravel>` | ||
dataset. | ||
|
||
The profiles are generated using a modified version of | ||
`SimBEV v0.1.3 <https://github.com/rl-institut/simbev/tree/1f87c716d14ccc4a658b8d2b01fd12b88a4334d5>`_. | ||
SimBEV generates driving profiles for battery electric vehicles (BEVs) and | ||
plug-in hybrid electric vehicles (PHEVs) based on MID survey data [MiD2017]_ per | ||
RegioStaR7 region type [RegioStaR7_2020]_. | ||
These profiles include driving, parking and (user-oriented) charging times. | ||
Different vehicle classes are taken | ||
into account whose assumed technical data is given in table :ref:`ev-types-data`. | ||
Moreover, charging probabilities for multiple types of charging | ||
infrastructure are presumed based on [NOW2020]_ and [Helfenbein2021]_. | ||
Given these assumptions, a pool of 33.000 EVs-types is pre-generated and provided through the data bundle | ||
(see :ref:`data-bundle-ref`) as well as written | ||
to table :py:class:`EgonEvTrip<egon.data.datasets.emobility.motorized_individual_travel.db_classes.EgonEvTrip>`. | ||
The complete tech data and assumptions of the run can be found in the | ||
metadata_simbev_run.json file, that is provided along with the trip data. | ||

Heavy-duty transport | ||
~~~~~~~~~~~~~~~~~~~~~ | ||
|
||
In the context of the eGon project, it is assumed that all e-trucks will be | ||
completely hydrogen-powered. The hydrogen demand data of all e-trucks is set up | ||
in the :py:class:`HeavyDutyTransport<egon.data.datasets.emobility.heavy_duty_transport.HeavyDutyTransport>` | ||
dataset for both the eGon2035 and eGon100RE scenario. | ||
|
||
In both scenarios the hydrogen consumption is | ||
assumed to be 6.68 kgH2 per 100 km with an additional supply chain leakage rate of 0.5 % | ||
(see `here <https://www.energy.gov/eere/fuelcells/doe-technical-targets-hydrogen-delivery>`_). | ||
|
||
For the eGon2035 scenario the ramp-up figures are taken from the | ||
`network development plan (version 2021) <https://www.netzentwicklungsplan.de/sites/default/files/paragraphs-files/NEP_2035_V2021_2_Entwurf_Teil1.pdf>`_ | ||
(Scenario C 2035). According to this, 100,000 e-trucks are | ||
expected in Germany in 2035, each covering an average of 100,000 km per year. | ||
In total this means 10 Billion km. | ||
|
||
For the eGon100RE scenario it is assumed that the heavy-duty transport is | ||
completely hydrogen-powered. The total freight traffic with 40 Billion km is | ||
taken from the | ||
`BMWK Langfristszenarien <https://www.langfristszenarien.de/enertile-explorer-wAssets/docs/LFS3_Langbericht_Verkehr_final.pdf#page=17>`_ | ||
for heavy-duty vehicles larger 12 t allowed total weight (SNF > 12 t zGG). | ||
|
||
The total hydrogen demand is spatially distributed on the basis of traffic volume data from [BASt]_. | ||
For this purpose, first a voronoi partition of Germany using the traffic measuring points is created. | ||
Afterwards, the spatial shares of the Voronoi regions in each NUTS3 area are used to allocate | ||
hydrogen demand to the NUTS3 regions and are then aggregated per NUTS3 region. | ||
The refuelling is assumed to take place at a constant rate. | ||
Finally, to | ||
determine the hydrogen bus where the hydrogen demand is allocated to, the centroid | ||
of each NUTS3 region is used to determine the respective hydrogen Voronoi cell (see | ||
:py:class:`GasAreaseGon2035<egon.data.datasets.gas_areas.GasAreaseGon2035>` and | ||
:py:class:`GasAreaseGon100RE<egon.data.datasets.gas_areas.GasAreaseGon100RE>`) it is | ||
located in. |
