class h2integrate.converters.methanol.methanol_baseclass.MethanolCostBaseClass(**kwargs)#

An OpenMDAO component for modeling the cost of a methanol plant. Includes CapEx, OpEx (fixed and variable), feedstock costs, and co-product credits.

Uses NETL power plant quality guidelines quantity of "total overnight cost" (TOC) for CapEx NETL-PUB-22580 doi.org/10.2172/1567736 Splits OpEx into Fixed and Variable (variable scales with capacity factor, fixed does not)

  • plant_capacity_flow: (str) flow that determines capacity, options: "hydrogen", "methanol"

  • toc_kg_y: (float) total overnight cost (TOC) slope - multiply by plant_capacity_kgpy to

    get CapEx

  • foc_kg_y^2: (float) fixed operating cost (FOC) slope - multiply by plant_capacity_kgpy to

    get Fixed_OpEx

  • voc_kg: (float) variable operating cost - multiply by methanol to get Variable_OpEx

  • methanol_out: (array) promoted output from MethanolPerformanceBaseClass

Outputs:

  • CapEx: all methanol plant capital expenses in the form of total overnight cost (TOC)

  • OpEx: all methanol plant operating expenses (fixed and variable)

  • Fixed_OpEx: all methanol plant fixed operating expenses (do NOT vary with production rate)

  • Variable_OpEx: all methanol plant variable operating expenses (vary with production rate)
