Hydrogen Fuel Cell Model

Hydrogen Fuel Cell Model#

The hydrogen fuel cell performance model implemented in H2Integrate is a linearized model that depends on the hydrogen inflow, fuel_cell_efficiency_hhv and system_capacity_kw to calculate the output electricity. The model will not allow negative electricity to be produced or more than the system_capacity_kw.

There are no non-linear considerations in this model such as warm-up delays, degraded performance over operational life, etc.

The hydrogen fuel cell cost model is implemented to use cost values that are in dollars per kilowatt (or per kilowatt per year) because that’s the typical reporting metric for hydrogen fuel cells.

Note

To ensure the hydrogen fuel cell is appropriately connected with other electricity producing technologies, the model name in the tech_config["technologies] needs to begin with h2_fuel_cell.
