HEAVY-DUTY REFUELING STATION ANALYSIS MODEL (HDRSAM)
Schematic overview of the HRSAM model
|
Overview |
|
|
HDRSAM model has been released for public
in 2017, with state of the art data on station configurations, component
technologies, and costs of interest to government agencies and industry
stakeholders.
|
|
|
|
Category |
|
|
Refueling techno-economic assessment
for a fleet of heavy-duty fuel cell electric vehicles.
|
|
|
|
Objectives |
|
|
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 heavy-duty fuel cell electric vehicles (HDFCEVs).

|
Key
Attributes |
|
|
The tool is highly flexible, allowing
end users the ability to change many detailed input assumptions
and to perform sensitivity analyses. HDRSAM 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.

Key Assumptions & Data Sources |
|
|
|
- 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).
|
|
|
|
Inputs |
|
|
|
- Fueling demand parameters.
- Cost and performance data of refueling components
as a function of throughput and manufacturing volume.
- Economic and financial parameters.
|
|
|
|
Outputs |
|
|
|
- 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.
