Industry sector¶

Key features¶

Optimisation of industry heat supply at two different temperature levels:

High-temperature (above 350°C)
Low-/medium-temperature (350°C or below)

The structure and functionality of components follow the PyPSA Components. The diagram below shows the full set of components involved in energy flows for a single industrial node.

Heat generators¶

The following component is defined as Generator in PyPSA.

Abbreviation	Full Name
`SWHT`	Solar hot water heater

Heat links¶

All the listed components are defined as Link in PyPSA.

Abbreviation	Full Name
`EERH`	Electric resistance heater
`EDLH`	Dielectric heating technology
`EHPP`	Industry heat pump
`EIDT`	Induction heat boiler
`FITR`	Fischer-Tropsch process
`IND_BOILER`	Industry heat boiler
`INLHSTOR`	Low-temperature heat storage
`METH`	Methanation

Fuel conversion¶

All the listed components are defined as Link in PyPSA.

Abbreviation	Full Name
`ELTZ`	Electrolyser (for hydrogen production)
`FITR`	Fischer-Tropsch process

Direct air capture¶

The following components is defined as Link in PyPSA.

Abbreviation	Full Name
`DAC`	Direct air capture

Storage capacity¶

The following component is defined as StorageUnit in PyPSA.

Tip

In PyPSA components, StorageUnit is modelled as a storage asset with a fixed energy-to-power ratio defined by max_hours of the nominal power (you can also refer to PyPSA Components - StorageUnit for more information).

To model the storage energy separately from the power capacity, Store + 2 Links is a better combination. You can refer to Storage energy for more information. Technologies defined in the storage energy require storage capacity if the carrier is related to electricity (power).

Abbreviation	Full Name
`INLHSTOR`	Low-temperature heat storage

Storage energy¶

All the listed components are defined as Store in PyPSA.

Tip

In PyPSA components, Store is modelled as a storage asset with only energy storage. It can optimise energy capacity separately from the power capacity with a combination of Store + 2 Links. The links represent charging and discharging characteristics to control the power output. Marginal cost and efficiency of charging and discharging can be defined in each link.

In the industry sector of PyPSA-SPICE model builder, the media electricity is replaced by low-temperature heat in the storage process. Technologies that are defined as storage energy, they should also be included in Storage capacity to describe charging and discharging processes. The links are created automatically, and hence it's not required to add charging and discharging links inside Heat links, Fuel conversion, or Direct air capture.

Detailed information and example can be found in PyPSA Components - Store and Replace StorageUnits with fundamental Links and Stores.

Abbreviation	Full Name
`INLHSTOR`	Low-temperature heat storage

Carriers¶

Abbreviation	Full Name
`Bio`	Biomass
`CO2`	Carbon dioxide (in the atmosphere)
