class h2integrate.converters.hydrogen.geologic.aspen_surface_processing.AspenGeoH2SurfacePerformanceConfig(size_from_wellhead_flow, max_flow_in, refit_coeffs, curve_input_fn, perf_coeff_fn)#

Configuration for performance parameters for a natural geologic hydrogen well surface processing system. This class defines performance parameters specific to natural geologic hydrogen systems (as opposed to stimulated systems).

Inherits from:

GeoH2SurfacePerformanceConfig

Variables:

  • refit_coeffs (bool) -- Whether to re-fit performance curves to ASPEN data. Set to False unless new Aspen data has been generated.

  • curve_input_fn (str) -- Filename of ASPEN model results file used to generate curve fits. Only used if refit_coeffs is True. Must be located in the ./inputs directory.

  • perf_coeff_fn (str) -- Filename of performance curve coefficients. Will be loaded if refit_coeffs is False and overwritten if refit_coeffs is True. Located in the ./inputs directory.

Parameters:

  • size_from_wellhead_flow (bool)

  • max_flow_in (float)

  • refit_coeffs (bool)

  • curve_input_fn (str)

  • perf_coeff_fn (str)
