Capital Cost

 

The parameters on the Capital Cost parameter screen define the financial assumptions associated with the construction and startup of hydrogen plants. The following parameters are available:

•Preproduction (Startup) Cost (%TPC): This cost considers the operator training, equipment checkout, major changes in unit equipment, extra maintenance, and inefficient use of fuel or other materials during start-up. It represents the percentage of Total Plant Cost (TPC) used to estimate expenses incurred during plant startup.

•Months of Operating Labor: This parameter defines the number of months of operating labor costs included during plant startup.

•Months of Maint. Matl. (full capacity): This parameter defines the number of months of maintenance material costs included during plant startup at full-capacity operation.

•Months of Non-Fuel Consumables (full capacity): This parameter defines the number of months of non-fuel consumables used during plant startup at full-capacity operation, including chemicals and catalysts, water, electricity, and waste disposal.

•Months of Waste Disp. (full capacity): This parameter defines the number of months of waste disposal costs included during plant startup at full-capacity operation.

•Fuel Cost (% of 1 month, full capacity): This parameter defines the percentage of one month of fuel costs included during plant startup at full-capacity operation.

•Inventory (Working) Capital (%TPC): This is the percent of the Total Plant Cost (TPC) for raw material supply based on 100% capacity during a 60- day period. These materials are considered storage. The inventory capital includes fuels, consumables, by-products, and spare parts.

•Months of Non-Fuel Consumables: This parameter defines the number of months of non-fuel consumables included in inventory capital calculations, including only chemicals and catalysts.

•Initial Cost for Catalysts & Chemicals: This parameter represents the initial cost of catalysts and chemicals required for plant operation per unit of hydrogen product.

•Other Owner’s Costs (%TPC): This is an additional lumped cost, including preliminary feasibility studies, economic development, construction and/or improvement of roads and/or railroad spurs outside of site boundary, legal fees, permitting costs, owner's engineering, and owner's contingency. This cost is site and owner specific. It is specified as a percentage of the TPC.

•Financing Cost (%TPC): This is the cost of securing financing (e.g., fees and closing costs). It is specified as a percentage of the TPC.

•Land Area: This parameter defines the land area required for the hydrogen plant.

•Land Cost: This is the unit cost of the land required for the hydrogen plant.

•TASC/TOC Multiplier: This financial parameter is used to estimate the Total As-Spent Cost (TASC) from the Total Overnight Cost (TOC).
