Tool Assumptions & Disclaimer

Main Assumptions

8760-hour chronological simulation with uploaded capacity factor profile.
Electrolyzer has priority; battery used for peak shaving.
Battery round-trip efficiency = 90% (95% charge / discharge).
Minimum load constraint: Electrolyzer runs only if power ≥ minimum load or stays OFF.
Brute-force optimization to minimize total annualized cost per kg H₂.
