class h2integrate.simulation.technologies.hydrogen.h2_storage.mch.mch_cost.MCHStorage(max_H2_production_kg_pr_hr, hydrogen_storage_capacity_kg, hydrogen_demand_kg_pr_hr, annual_hydrogen_stored_kg_pr_yr)#

Cost model representing a toluene/methylcyclohexane (TOL/MCH) hydrogen storage system.

Costs are in 2024 USD.

Breunig, H., Rosner, F., Saqline, S. et al. "Achieving gigawatt-scale green hydrogen production and seasonal storage at industrial locations across the U.S." Nat Commun 15, 9049 (2024). https://doi.org/10.1038/s41467-024-53189-2

Parameters:

  • max_H2_production_kg_pr_hr (float) -- Maximum amount of hydrogen that may be used to fill storage in kg/hr.

  • hydrogen_storage_capacity_kg (float) -- Hydrogen storage capacity in kilograms.

  • hydrogen_demand_kg_pr_hr (float) -- Hydrogen demand in kg/hr.

  • annual_hydrogen_stored_kg_pr_yr (float) -- Sum of hydrogen used to fill storage in kg/year.

Note

Hydrogenation capacity (HC) should be sized to allow for peak hydrogen charge rate. Dehydrogenation capacity (DC) sized to assume that end-use requires a consistent H2 supply. Maximum storage capacity (MS) is the maximum consecutive quantity of H2 stored

with lowest frequency of discharge.

Annual hydrogen storage (AS) is the hydrogen curtailed from production into storage.
