Since its initial public release in 2014, HRSAM has been expanded and updated with state of the art data on station configurations, component technologies, and costs of interest to government agencies and industry stakeholders.

Refueling techno-economic assessment for light-duty fuel cell electric vehicles.

Provide platform for comparing the cost of alternative hydrogen refueling options. Identify cost drivers of current hydrogen refueling technologies for various station configurations, and demand profiles of fuel cell electric vehicles (FCEVs).

The tool is highly flexible, allowing end users the ability to change many detailed input assumptions and to perform sensitivity analyses. HRSAM evaluates the cost of hydrogen refueling for various fueling station configurations and demand profiles. The model incorporates optimization algorithms to identify least cost refueling configurations. All assumptions and calculations are transparent and key components and drivers of cost are easily identified.

• Cost of capital from vendors, industry and literature, and other economic parameters from H2A model system.
• Depreciation and labor rates based on industry input.
• Land requirements based on NFPA codes and standards.
• Process and equipment technical information based on industry input and basic engineering calculations.
• Cost of energy from the U.S. Energy Information Administration (EIA).

• Fueling demand parameters.
• Cost and performance data of refueling components as a function of throughput and manufacturing volume.
• Economic and financial parameters.

• Levelized cost [$/kg] of hydrogen refueling.
• Contribution of station components to levelized cost of hydrogen.
• Capital, operating and maintenance costs of station components (e.g., compressors, cryogenic pumps, pre-cooling units, and dispensers).
• Annual and cumulative cash flows by station components and total.
• Land area, energy use, efficiency, leakage, boil-off and emissions.

The HRSAM model uses an Excel-based platform with graphical user interface, and is freely available to the public (see below for download link).

Gaseous Hydrogen from Supply -> High Pressure Compressor -> High Pressure Buffer Storage-> Pre-Cooling Unit -> Dispenser

Gaseous Hydrogen from Supply -> Medium Pressure Compressor -> Medium Pressure Buffer Storage-> Booster Compressor ->Accumulator -> Pre-Cooling Unit -> Dispenser

Liquid/Cold Gaseous Hydrogen from Supply -> Heat Exchanger -> High Pressure Compressor -> High Pressure Buffer Storage-> Pre-Cooling Unit -> Dispenser

Liquid Hydrogen from Supply -> High Pressure Pump -> Evaporator -> High Pressure Buffer Storage -> Pre-Cooling Unit -> Dispenser

HDSAM must be run in Microsoft Excel 2010® for full functionality. The model is available as an open-source software package copyright by UChicago Argonne, LLC. Prior to downloading the model, users must register.
