ResizeablePerformanceModelBaseClass(**kwargs)	Baseclass to be used for all resizeable performance models.

class h2integrate.core.model_baseclasses.CostModelBaseClass(**kwargs)

Baseclass to be used for all cost models. The built-in outputs are used by the finance model and must be outputted by all cost models.

Outputs:

• CapEx (float): capital expenditure costs in $

• OpEx (float): annual fixed operating expenditure costs in $/year

• VarOpEx (float): annual variable operating expenditure costs in $/year

Discrete Outputs:

• cost_year (int): dollar-year corresponding to CapEx and OpEx values.

  This may be inherent to the cost model, or may depend on user provided input values.

initialize()

Perform any one-time initialization run at instantiation.

setup()

Declare inputs and outputs.

Available attributes:

name pathname comm options

compute(inputs, outputs, discrete_inputs, discrete_outputs)

Computation for the OM component.

For a template class this is not implement and raises an error.

class h2integrate.core.model_baseclasses.ResizeablePerformanceModelBaseClass(**kwargs)

Baseclass to be used for all resizeable performance models. The built-in inputs are used by the performance models to resize themselves.

These parameters are all set as attributes within the config class, which inherits from h2integrate.core.utilities.ResizeablePerformanceModelBaseConfig

Discrete Inputs:

• size_mode (str): The mode in which the component is sized. Options:

  • "normal": The component size is taken from the tech_config.

  • "resize_by_max_feedstock": The component size is calculated relative to the

    maximum available amount of a certain feedstock or feedstocks

  • "resize_by_max_commodity": The electrolyzer size is calculated relative to the

    maximum amount of the commodity used by another tech

• flow_used_for_sizing (str): The feedstock/commodity flow used to determine the plant size

  in "resize_by_max_feedstock" and "resize_by_max_commodity" modes

Inputs:

• max_feedstock_ratio (float): The ratio of the max feedstock that can be consumed by

  this component to the max feedstock available.

• max_commodity_ratio (float): The ratio of the max commodity that can be produced by

  this component to the max commodity consumed by the downstream tech.
