EXTRACT

The EXTRACT phase consists of the following steps:

• Extraction and cleaning of the ecoinvent database

• Import and cleaning of additional inventories

• Import and cleaning of user-provided inventories (optional)

• Caching, if these database and inventories are imported for the first time

• Loading of IAM data

Current IAM scenarios

premise includes several Integrated Assessment Model (IAM) scenarios, but you can also use other scenarios. In premise, scenarios are defined by their Shared Socio-economic Pathway (SSP), a climate trajectory—often represented by a Representative Concentration Pathway (RCP)—and a year (e.g., SSP1, Base, 2035).

SSP/RCP scenario	GMST increase by 2100	Society/economy trend	Climate policy	REMIND	IMAGE
SSP1-None	2.3-2.8 °C	Optimistic trends for human develop. and economy, driven by sustainable practices.	None	SSP1-Base	SSP1-Base
SSP1-None	~2.2 °C	Optimistic trends for human develop. and economy, driven by sustainable practices.	National Policies Implemented (NPI).	SSP1-NPi

SSP5-RCP1.9	~1.0 °C	Optimistic trends for human develop. and economy, driven by fossil fuels.	Paris Agreement objective.	SSP5-PkBudg500

Note

A summary report of the main variables of the scenarios selected is generated automatically after each database export. There is also an online dashboard. You can also generate it manually:

Supported versions of ecoinvent

premise currently works with the following ecoinvent database versions:

• v.3.5, cut-off

• v.3.6, cut-off

• v.3.7, cut-off

• v.3.7.1, cut-off

• v.3.8, cut-off and consequential

• v.3.9/3.9.1, cut-off and consequential

Supported sources of ecoinvent

premise can extract the ecoinvent database from:

• a brightway2 project that contains the ecoinvent database

• ecosposld2 files, that can be downloaded from the ecoinvent website

Note

The ecoinvent database is not included in premise. You need to have a valid license to download and use it. Also, please read carefully ecoinvent’s EULA before using premise.

From a brightway2 project

To extract from an ecoinvent database located in a brightway2 project, simply indicate the database name in source_db and its version in source_version:

from premise import *
import brightway2 as bw

bw.projects.set_current("my_project)

ndb = NewDatabase(
      scenarios=[
              {"model":"remind", "pathway":"SSP2-Base", "year":2028}
          ],
      source_db="ecoinvent 3.7 cutoff", # <-- this is NEW.
      source_version="3.7.1", # <-- this is NEW
      key='xxxxxxxxxxxxxxxxxxxxxxxxx',
      use_multiprocessing=True, # True by default, set to False if multiprocessing is causing troubles
      keep_uncertainty_data=False # False by default, set to True if you want to keep ecoinvent's uncertainty data
  )

Note that a cache of the database will be created the first time and store in the library folder. Any subsequent creation of databases using the same ecoinvent version will no longer require this extraction step.

If you wish to clear that cache folder, do:

from premise import *

clear_cache()

Note

It is recommended to restart your notebook once the data has been cached for the first time, so that the remaining steps can be performed using the cached data (much faster).

From ecospold2 files

To extract from a set of ecospold2 files, you need to point to the location of those files in source_file_path, as well as indicate the database format in source_type:

from premise import *

ndb = NewDatabase(
    scenarios = [
        {"model":"remind", "pathway":"SSP2-Base", "year":2028}
                ],
    source_type="ecospold", # <--- this is NEW
    source_file_path=r"C:\file\path\to\ecoinvent 3.5_cutoff_ecoSpold02\datasets", # <-- this is NEW
    source_version="3.5",
)

Import of additional inventories

After the ecoinvent database is extracted and checked, a number of additional inventories are imported, regardless of the year of scenario that is being considered.

Power generation

A number of datasets relating to power generation not originally present in ecoinvent are imported. The next sub-sections lists such datasets.

Power plants with CCS

Datasets for power generation with Carbon Capture and Storage (CCS) are imported. They originate from Volkart et al. 2013, and can be consulted here: LCI_Power_generation. An exception to this are the inventories for biomass-based integrated gasification combined cycle power plants (BIGCCS), which are from Briones-Hidrovo et al, 2020.

The table below lists the names of the new activities (only production datasets are shown).

Natural gas

Updated inventories relating to natural gas extraction and distribution are imported to substitute some of the original ecoinvent dataset. These datasets originate from ESU Services and come with a report, and can be consulted here: LCI_Oil_NG.

They have been adapted to a brightway2-compatible format. These new inventories have, among other things, higher methane slip emissions along the natural gas supply chain, especially at extraction.

Original dataset	Replaced by
natural gas production (natural gas, high pressure), DE	natural gas, at production (natural gas, high pressure), DE
natural gas production (natural gas, high pressure), DZ	natural gas, at production (natural gas, high pressure), DZ

In the report, the generation potential per installation type is multiplied by the number of installations in each country, to produce country-specific PV power mix datasets normalized to 1 kWh. The report specifies the production-weighted PV mix for each country, but we further split it between residential (<=3kWp) and commercial (>3kWp) installations (as most IAMs make such distinction):

Hence, inside the residential PV mix of Spain (“electricity production, photovoltaic, residential”), one will find the following inputs for the production of 1kWh:

name	amount	location	unit
Energy, solar, converted	3.8503		megajoule

with, for example, 2.48E-8 units of “photovoltaic slanted-roof installation, 3 kWp, CIS, laminated, integrated, on roof” being calculated as:

1 / (30 [years] * 1423 [kWh/kWp] * 0.32% [share of PV capacity of such type installed in Spain])

Note that commercial PV mix datasets provide electricity at high voltage, unlike residential PV mix datasets, which supply at low voltage only.

Geothermal

Heat production by means of a geothermal well are not represented in ecoinvent. The geothermal power plant construction inventories are from Maeder Bachelor Thesis.

Hydrogen storage and distribution

A number of datasets relating to hydrogen storage and distribution are also imported.

They are necessary to model the distribution of hydrogen:

• via re-assigned transmission and distribution CNG pipelines, in a gaseous state

• via dedicated transmission and distribution hydrogen pipelines, in a gaseous state

• as a liquid organic compound, by hydrogenation

• via truck, in a liquid state

• hydrogen refuelling station

Small and large storage solutions are also provided: * high pressure hydrogen storage tank * geological storage tank

These datasets originate from the work of Wulf et al. 2018, and can be consulted here: LCI_H2_distr. For re-assigned CNG pipelines, which require the hydrogen to be mixed together with oxygen to limit metal embrittlement, some parameters are taken from the work of Cerniauskas et al. 2020.

The datasets introduced are listed in the table below.

Hydrogen distribution	location

Hydrogen turbine

A dataset for a hydrogen turbine is also imported, to model the production of electricity from hydrogen, with an efficiency of 51%. The efficiency of the H2-fed gas turbine is based on the parameters of Ozawa et al. (2019), accessible here: LCI_H2_turbine.

Biofuels

Inventories for energy crops- and residues-based production of bioethanol and biodiesel are imported, and can be accessed here: LCI_biofuels. They include the farming of the crop, the conversion of the biomass to fuel, as well as its distribution. The conversion process often leads to the production of co-products (dried distiller’s grain, electricity, CO2, bagasse.). Hence, energy, economic and system expansion partitioning approaches are available. These inventories originate from several different sources (Wu et al. 2006 (2020 update), Cozzolino 2018, Pereira et al. 2019 and Gonzalez-Garcia et al. 2012), Cavalett & Cherubini 2022, as indicated in the table below.

Synthetic fuels

premise imports inventories for the synthesis of hydrocarbon fuels following two pathways:

• Fischer-Tropsch: it uses hydrogen and CO (from CO2 via a reverse water gas shift process) to produce “syncrude”, which is distilled into diesel, kerosene, naphtha and lubricating oil and waxes. Inventories are from van der Giesen et al. 2014.

• Methanol-to-liquids: methanol is synthesized from hydrogen and CO2, and further distilled into gasoline, diesel, LGP and kerosene. Synthetic methanol inventories are from Hank et al. 2019. The methanol to fuel process specifications are from FVV 2013.

• Electro-chemical methanation: methane is produced from hydrogen and CO2 using a Sabatier methanation reactor. Inventories are from Zhang et al, 2019.

In their default configuration, these fuels use hydrogen from electrolysis and CO2 from direct air capture (DAC). However, premise builds different configurations (i.e., CO2 and hydrogen sources) for these fuels, for each IAM region:

In the case of wood and coal gasification-based fuels, the CO2 needed to produce methanol or syncrude originates from the gasification process itself. This also implies that in the methanol and/or RWGS process, a carbon balance correction is applied to reflect the fact that a part of the CO2 from the gasification process is redirected into the fuel production process.

If the CO2 originates from:

• a gasification process without CCS, a negative carbon correction is added to

reflect the fact that part of the CO2 has not been emitted but has ended in the fuel instead. * the gasification process with CCS, no carbon correction is necessary, because the CO2 is stored in the fuel instead of being stored underground, which from a carbon accounting standpoint is similar.

Carbon Capture

Two sets of inventories for Direct Air Capture (DAC) are available in premise. One for a solvent-based system, and one for a sorbent-based system. The inventories were developed by Qiu and are available in the LCI_DAC spreadsheet. For each, a variant including the subsequent compression, transport and storage of the captured CO2 is also available.

They can be consulted here: LCI_DAC.

Additional, two datasets for carbon capture at point sources are available: one at cement plant from Meunier et al, 2020, and another one at municipal solid waste incineration plant (MSWI) from Bisinella et al, 2021.

They introduce the following datasets:

Activity	Location
carbon dioxide, captured from atmosphere, with a sorbent-based direct air capture system, 100ktCO2	RER
carbon dioxide, captured from atmosphere and stored, with a sorbent-based direct air capture system, 100ktCO2	RER
carbon dioxide, captured from atmosphere, with a solvent-based direct air capture system, 1MtCO2	RER
carbon dioxide, captured from atmosphere and stored, with a solvent-based direct air capture system, 1MtCO2	RER
carbon dioxide, captured at municipal solid waste incineration plant, for subsequent reuse	RER
carbon dioxide, captured at cement production plant, for subsequent reuse	RER

Using the transformation function update(“dac”), premise creates various configurations of these processes, using different sources for heat (industrial steam heat, high-temp heat pump heat and excess heat), which are found under the following names, for each IAM region:

name	location
carbon dioxide, captured from atmosphere, with a solvent-based direct air capture system, 1MtCO2, with industrial steam heat, and grid electricity	all IAM regions
carbon dioxide, captured from atmosphere, with a solvent-based direct air capture system, 1MtCO2, with heat pump heat, and grid electricity	all IAM regions
carbon dioxide, captured from atmosphere, with a sorbent-based direct air capture system, 100ktCO2, with waste heat, and grid electricity	all IAM regions
carbon dioxide, captured from atmosphere, with a sorbent-based direct air capture system, 100ktCO2, with industrial steam heat, and grid electricity	all IAM regions
carbon dioxide, captured from atmosphere, with a sorbent-based direct air capture system, 100ktCO2, with heat pump heat, and grid electricity	all IAM regions

Note that only solid sorbent DAC can use waste heat, as the heat requirement for liquid solvent DAC is too high (~900 C)

Li-ion batteries

When using ecoinvent 3.8 as a database, premise imports new inventories for lithium-ion batteries. NMC-111, NMC-6222 NMC-811 and NCA Lithium-ion battery inventories are originally from Dai et al. 2019. They have been adapted to ecoinvent by Crenna et al, 2021. LFP and LTO Lithium-ion battery inventories are from Schmidt et al. 2019. Li-S battery inventories are from Wickerts et al. 2023. Li-O2 battery inventories are from Wang et al. 2020. Finally, SIB battery inventories are from Zhang22 et al. 2024.

They introduce the following datasets:

Battery components	location	source
battery management system production, for Li-ion battery	GLO	Schmidt et al. 2019
battery cell production, Li-ion, NMC111	GLO	Dai et al. 2019, Crenna et al. 2021

battery cell production, Li-O2	GLO	Wang et al. (2020)
battery cell production, SIB	GLO	Zhang et al. (2024)

These battery inventories are mostly used by battery electric vehicles, stationary energy storage systems, etc. (also imported by premise).

NMC-111, NMC-811, LFP and NCA inventories can be found here: LCI_batteries1. NMC-622 and LTO inventories can be found here: LCI_batteries2. Li-S inventories can be found here: LCI_batteries3. Li-O2 inventories can be found here: LCI_batteries4. And SIB inventories can be found here: LCI_batteries5.

When using ecoinvent 3.9 and above, the NMC-111, NMC-811, LFP and NCA battery inventories are not imported (as are already present the ecoinvent database).

Graphite

premise includes new inventories for:

• natural graphite, from Engels et al. 2022,

• synthetic graphite, from Surovtseva et al. 2022,

forming a new market for graphite, with the following datasets:

Activity	Location
market for graphite, battery grade		1.0
graphite, natural	CN	0.8
graphite, synthetic	CN	0.2

to represent a 80:20 split between natural and synthetic graphite, according to Surovtseva et al, 2022.

These inventories can be found here: LCI_graphite.

Cobalt

New inventories of cobalt are added, from the work of Dai, Kelly and Elgowainy, 2018. They are available under the following datasets:

Activity	Location
cobalt sulfate production, from copper mining, economic allocation	CN
cobalt sulfate production, from copper mining, energy allocation	CN
cobalt metal production, from copper mining, via electrolysis, economic allocation	CN
cobalt metal production, from copper mining, via electrolysis, energy allocation	CN

We recommend using those rather than the original ecoinvent inventories for cobalt, provided by the Cobalt Development Institute (CDI) since ecoinvent 3.7, which seem to lack transparency.

These inventories can be found here: LCI_cobalt.

Lithium

New inventories for lithium extraction are also added, from the work of Schenker et al., 2022. They cover lithium extraction from five different locations in Chile, Argentina and China. They are available under the following datasets for battery production:

Activity	Location
market for lithium carbonate, battery grade	GLO
market for lithium hydroxide, battery grade	GLO

These inventories can be found here: LCI_lithium.

Vanadium Redox Flow Batteries

premise imports inventories for the production of a vanadium redox flow battery, used for grid-balancing, from the work of Weber et al. 2021. It is available under the following dataset:

• vanadium-redox flow battery system assembly, 8.3 megawatt hour

The dataset providing electricity is the following:

• electricity supply, high voltage, from vanadium-redox flow battery system

The power capacity for this application is 1MW and the net storage capacity 6 MWh. The net capacity considers the internal inefficiencies of the batteries and the min Sate-of-Charge, requiring a certain oversizing of the batteries. For providing net 6 MWh, a nominal capacity of 8.3 MWh is required for the VRFB with the assumed operation parameters. The assumed lifetime of the stack is 10 years. The lifetime of the system is 20 years or 8176 cycle-life (49,000 MWh).

These inventories can be found here: LCI_vanadium_redox_flow_batteries.

This publication also provides LCIs for Vanadium mining and refining from iron ore. The end product is vanadium pentoxide, which is available under the following dataset:

• vanadium pentoxide production

These inventories can be found here: LCI_vanadium.

Inventories are from Sacchi et al. 2021. The vehicles are available for different years and emission standards and for each IAM region. premise will only import vehicles which production year is equal or inferior to the scenario year considered. premise will create fleet average vehicles during the Transport transformation for each IAM region. The inventories can be consulted here: LCIbuses.

At the moment. these inventories do not supply inputs to other activities in the LCI database. As such, they are optional.

Migration between ecoinvent versions

Because the additional inventories that are imported may be composed of exchanges meant to link with an ecoinvent version different than what the user specifies to premise upon the database creation, it is necessary to be able to “translate” the imported inventories so that they correctly link to any ecoinvent version premise is compatible with.

Therefore, premise has a migration map that is used to convert certain exchanges to be compatible with a given ecoinvent version.

This migration map is provided here: migrationmap.

IAM data collection

After extracting the ecoinvent database and additional inventories, premise instantiates the class IAMDataCollection, which collects all sorts of data from the IAM output file and store it into multi-dimensional arrays.

Production volumes

Production volumes for different commodities are collected, for the year and scenario specified by the user. Production volumes are used to build regional markets. For example, for the global market, the volume-based shares of each region are used to reflect their respective supply importance. Another example is for building electricity markets: the respective production volumes of each electricity-producing technology is used to determine the gross supply mix of the market.

The table below shows a non-exhaustive list of correspondences between premise, REMIND, IMAGE and LCI terminology, regarding electricity producing technologies. premise production volumes given for secondary energy carriers for electricity. The mapping file is available in the library root folder: mappingElec_.

Note

IAMs do not necessarily display the same variety of technologies. For example, REMIND does not provide a variable for residential PV production while IMAGE does.

Note

Because of a lack of more diverse inventories, wind power is only represented with relatively small installations (< 1MW, 1-3 MW and >3 MW), in respect to today’s standard. This can lead to overestimate the associated environmental burden.

The table below shows the correspondence between premise, REMIND, IMAGE and LCI terminology, regarding steel and cement producing technologies. The mapping files are available in the library root folder: mappingCement and mappingSteel.

name in premise	name in REMIND	name in IMAGE	name in LCI database
cement	Production|Industry|Cement	Production|Cement	cement production, Portland
steel - primary	Production|Industry|Steel|Primary	Production|Steel|Primary	steel production, converter
steel - secondary	Production|Industry|Steel|Secondary	Production|Steel|Secondary	steel production, electric

The table below shows the correspondence between premise, REMIND, IMAGE and LCI terminology, regarding fuel producing technologies. The mapping file is available in the library root folder: mappingFuels.

Warning

Some fuel types are not properly represented in the LCI database. Available inventories for biomass-based methanol production do not differentiate between wood and grass as the feedstock.

Note

Modelling choice: premise builds several potential supply chains for hydrogen. Because the logistics to supply hydrogen in the future is not known or indicated by the IAM, the choice is made to supply it by truck over 500 km, in a gaseous state.

The production volumes considered for a given scenario can be consulted, like so:

Efficiencies

The efficiency of the different technologies producing commodities (e.g., electricity, steel, cement, fuel) is modelled to change over time by the IAM. premise stores the relative change in efficiency of such technologies.

The table below shows the correspondence between premise, REMIND, IMAGE, regarding efficiency variables for electricity producing technologies. The mapping file is available in the library root folder: mappingElec_.

The table below shows the correspondence between premise, REMIND, IMAGE, regarding efficiency variables for cement and steel producing technologies. For cement and steel, it is different, as premise derives efficiencies by dividing the the final energy demand by the production volume (to obtain GJ/t steel or cement). This is because efficiency variables for cement and steel is not always given as such. The mapping files are available in the library root folder: mappingCement and mappingSteel.

premise stores the change in efficiency (called scaling factor) of a given technology relative to 2020. This is based on the fact that the efficiency of ecoinvent datasets are believed to reflect current (2020) efficiency.

Note

If a technology, in a given region, is given a scaling factor of 1.2 in 2030, this means that the corresponding ecoinvent dataset is adjusted so that its efficiency is improved by 20% (by multiplying the dataset inputs by 1/1.2). In other words, premise does not use the efficiency given by the IAM, but rather its change over time relative to 2020.

The scaling factors considered for a given scenario can be consulted, like so:

ndb.scenarios[0]["iam data"].efficiency

Land use and land use change

When building prospective databases using the IAM IMAGE model, the latter provides additional variables relating to average land use and land use change emissions, for each type of crop grown to be used in biofuel production. Upon the creation of biofuel supply chains in the Fuels transformation function, such information is used to adjust the inventories of crop farming datasets. The table below shows the IMAGE variables used to that effect. The mapping file is available in the library root folder: mappingCrops.

Crop family in premise	Crop type in premise	Land use variable in IMAGE [Ha/GJ-Prim]	Land use change variable in IMAGE [kg CO2/GJ-Prim]
sugar	sugarbeet, sugarcane	Land Use|Average|Biomass|Sugar	Emission Factor|CO2|Energy|Supply|Biomass|Average|Sugar
oil	rapeseed, palm oil	Land Use|Average|Biomass|OilCrop	Emission Factor|CO2|Energy|Supply|Biomass|Average|Oilcrops
wood	poplar, eucalyptus	Land Use|Average|Biomass|Woody	Emission Factor|CO2|Energy|Supply|Biomass|Average|Woody
grass	switchgrass, miscanthus	Land Use|Average|Biomass|Grassy	Emission Factor|CO2|Energy|Supply|Biomass|Average|Grassy
grain	corn	Land Use|Average|Biomass|Maize	Emission Factor|CO2|Energy|Supply|Biomass|Average|Maize

The land use and land use change emissions considered for a given scenario can be consulted, like so:

ndb.scenarios[0]["iam data"].land_use_change

Carbon Capture and Storage

Some scenarios involve the capture and storage of CO2 emissions of certain sectors (e.g., cement and steel). The capture rate of a given sector is calculated from the IAM data file, as:

rate = amount of CO2 captured / (amount of CO2 captured + amount of CO2 not captured)

The table below lists the variables needed to calculate those rates.

name in premise	name in REMIND	name in IMAGE
cement - CO2 (not captured)	Emi|CO2|FFaI|Industry|Cement	Emissions|CO2|Industry|Cement|Gross
cement - CCO2 (captured)	Emi|CCO2|FFaI|Industry|Cement	Emissions|CO2|Industry|Cement|Sequestered
steel - CO2 (not captured)	Emi|CO2|FFaI|Industry|Steel	Emissions|CO2|Industry|Steel|Gross
steel - CCO2 (captured)	Emi|CCO2|FFaI|Industry|Steel	Emissions|CO2|Industry|Steel|Sequestered

The carbon capture rates which are floating values comprised between 0 and 1, can be consulted like so:

ndb.scenarios[0]["iam data"].carbon_capture_rate

Data sources external to the IAM

premise tries to adhere to the IAM scenario data as much as possible. There are however a number of cases where external data sources are used. This is notably the case for non-CO2 pollutants emissions for different sectors (electricity, steel and cement), as well as expected efficiency gains for photovoltaic panels.

Air emissions

premise relies on projections from the air emissions models GAINS-EU and GAINS-IAM to adjust the emissions of pollutants for different sectors. As with efficiencies, premise stores the change in emissions (called scaling factor) of a given technology relative to 2020. This is based on the fact that the emissions of ecoinvent datasets are believed to reflect the current (2020) situation. Hence, if a technology, in a given region, has a scaling factor of 1.2 in 2030, this means that the corresponding ecoinvent dataset is adjusted so that its emissions of a given substance is improved by 20%. In other words, premise does not use the emissions level given by GAINS, but rather its change over time relative to 2020.

For more information about this step, refer to sub-section “GAINS emission factors” in the EXTRACT section.

Photovoltaic panels

Module efficiencies in 2010 for micro-Si and single-Si are from IEA_ Task 12 report. For multi-Si, CIGS, CIS and CdTe, they are from IEA2 road map report on PV panels.

Current (2020) module efficiencies for all PV types are given by a 2021 report from the Fraunhofer Institute.

The efficiencies indicated for 2050 are what has been obtained in laboratory conditions by the Fraunhofer Institute. In other words, it is assumed that by 2050, solar PVs will reach production level efficiencies equal to those observed today in laboratories.

% module efficiency	micro-Si	single-Si	multi-Si	CIGS	CIS	CdTe
2010	10	15.1	14	11	11	10
2020	11.9	17.9	16.8	14	14	16.8
2050	12.5	26.7	24.4	23.4	23.4	21
