CO2 sequestration (t)#

indexed by: asset, data type, node, technology and test case

Description#

This indicator is used to analyse the total volumes of sequestrated CO2 for a given asset over the entire optimization horizon, and their maximal potentials.

The volume of sequestrated CO2 is determined as the sum over the period of the consumption of CO2 captured. This consumption of CO2 captured goes under the Sequestration tag.

The maximal potential goes under the Potential tag and depends on the considered technology:

For CO2 captured sequestration assets, it is the sum over the period of the maximum consumption of the asset
For wells, as the assets do not have any maximum consumption, it is set at 0

Modelling hint

Note that the potential can be lower than the sequestration when wells are used in the context, as it is not possible to compute a maximum consumption for these assets. If sufficient data is available, it is preferable to use assets of type CO2 captured sequestration.

Calculation#

All the equations below are valid for any realization and are therefore implicitly indexed by test case. Index Technology is directly deduced from the asset. The assets considered in this KPI are those within the Well type , (currently only wells and CO2 captured sequestration assets).

Sequestration#

Let be \(x_{a, n}\) the value returned by the data type Sequestration for a given asset \(a\) and node \(n\). We can then express \(x_{a, n}\) as:

\[x_{a, n} = \frac{1}{N_h} * \sum_{\text{timestep } t} c_{a, CO_{2} captured, n}(t)\]

Potential#

Let be \(x_{a, n}\) the value returned by the data type Potential for a given asset \(a\) and node \(n\). We can then express \(x_{a, n}\) as:

\[x_{a, n} = \frac{1}{N_h} * \sum_{\text{timestep } t} p^{*, IN}_a(t)\]

Indexing#

The asset index refers to the name of the asset (wells that consume CO2 captured or CO2 captured sequestration assets only)
The node index of this KPI refers to the node in which the asset sequestrates CO2 captured
The technology index refers to the technology type of the asset
The test case index corresponds the test case of the realization variables and parameters are taken from
