Public interface

EnergyModelsCO2 is representing several technologies that are relevant within CO₂ capture, transport, utilization, and storage chains.

CO2Source <: Source

A CO₂ Source node. Its only difference from a RefSource is that is allows for CO₂ as outlet.

Fields

• id is the name/identifier of the node.
• cap::TimeProfile is the installed capacity.
• opex_var::TimeProfile is the variational operational costs per energy unit produced.
• opex_fixed::TimeProfile is the fixed operational costs.
• output::Dict{<:Resource, <:Real} are the generated Resources with conversion value Real.
• data::Array{<:Data} is the additional data (e.g. for investments). The field data is conditional through usage of a constructor.

CO2Storage{T} <: Storage{T}

This node has an installed injection rate capacity through charge and a storage capacity level.

The storage level (accountet by the optimization variable stor_level) will increase during all strategic periods (sp), i.e., the stored resource can not be taken out of the storage.

The initial storage level in a strategic period is set to the storage level at the end of the prevoious sp. Note that the increased storage level during a sp is multiplied with the length of the sp when the initial storage level for the next sp is set.

This is achieved through the parametric input AccumulatingStrategic. This input is not a required input due to the utilization of an inner constructor.

Fields

• id is the name/identifyer of the node.
• charge::EMB.UnionCapacity are the charging parameters of the CO2Storage node. Depending on the chosen type, the charge parameters can include variable OPEX and/or fixed OPEX.
• level::EMB.UnionCapacity are the level parameters of the CO2Storage node. Depending on the chosen type, the charge parameters can include variable OPEX and/or fixed OPEX.
• stor_res::Resource is the stored Resource.
• input::Dict{<:Resource, <:Real} are the input Resources with conversion value Real.
• data::Array{<:Data} is the additional data (e.g. for investments). The field data is conditional through usage of a constructor.

NetworkNodeWithRetrofit <:NetworkNode

Abstract supertype for allowing retrofitting CO₂ capture to a node. Its application requires the user to

1. define their own node as subtype of NetworkNodeWithRetrofit and
2. include a field co2_proxy in said node or alternatively define a method for co2_proxy for the node.

The application is best explained by RefNetworkNodeRetrofit which illustrates it for a RefNetworkNode node.

RefNetworkNodeRetrofit <: NetworkNodeWithRetrofit

This node allows for retrofitting CO₂ capture to a NetworkNode.

It corresponds to a RefNetworkNode node in which the CO₂ is not emitted. Instead, it is transferred to a co2_proxy that is fed subsequently to a node (CCSRetroFit) in which it is either captured, or emitted.

The co2_proxy does not have to be specified as output resource.

Fields

• id is the name/identifier of the node.
• cap::TimeProfile is the installed capacity.
• opex_var::TimeProfile is the variational operational costs per energy unit produced.
• opex_fixed::TimeProfile is the fixed operational costs.
• input::Dict{<:Resource, <:Real} are the input Resources with conversion value Real.
• output::Dict{<:Resource, <:Real} are the generated Resources with conversion value Real. co2_proxy is required to be included to be available to have CO₂ capture applied properly.
• co2_proxy::Resource is the instance of the Resource used for calculating internally the CO₂ flow from the RefNetworkNodeRetrofit to the CCSRetroFit node.
• data::Array{<:Data} is the additional data (e.g. for investments).

CCSRetroFit <: Network

This node allows for investments into CO₂ capture retrofit to a RefNetworkNodeRetrofit node. The capture process is implemented through the variable :cap_use

The co2_proxy does not have to be specified as input resource.

Fields

• id is the name/identifier of the node.
• cap::TimeProfile is the installed capacity.
• opex_var::TimeProfile is the variational operational costs per unit CO2 captured.
• opex_fixed::TimeProfile is the fixed operational costs.
• input::Dict{<:Resource, <:Real} are the input Resources with conversion value Real.
• output::Dict{<:Resource, <:Real} are the generated Resources with conversion value Real. The CO₂ instance is required to be included to be available to have CO₂ capture applied properly.
• co2_proxy::Resource is the instance of the Resource used for calculating internally the CO₂ flow from the RefNetworkNodeRetrofit to the CCSRetroFit node.
• data::Array{<:Data} is the additional data (e.g. for investments).

NetworkCCSRetrofit(args)

Legacy constructor NetworkCCSRetrofit This type was renamed to RefNetworkNodeRetrofit while everything else remains the same.

CaptureFlueGas{T} <: CaptureData{T}

Capture the proxy CO₂ instance but not the energy usage related emissions and the process emissions. Does not require emissions as input, but can be supplied.

Fields

• emissions::Dict{ResourceEmit, T} are the emissions per unit produced.
• co2_capture::Float64 is the CO₂ capture rate.

CaptureNone(emissions::Dict{ResourceEmit,T}, co2_capture::Float64)

Legacy constructor for a CaptureNone. This type was renamed to CaptureFlueGas while everything else remains the same.
