Thermodynamic and Economic Assessment of a Liquid Nitrogen Precooling Dual-Pressure Claude Cycle for Hydrogen Liquefaction

Techno-economic assumptions • Table S2: Cost categories and baseline TEA assumptions (capital depreciation, power consumption, maintenance, labor, and miscellaneous operating costs). • Table S3: Financial and operational parameters, including capital cost, plant lifetime, production scale, electricity/LN2 prices, discount rate, and depreciation method. 4. Parametric and sensitivity analyses • Table S4: Influence of LN2 mass-flow rate on refrigeration-load distribution, cold-box pressure drops, and temperature-profile uniformity. • Table S5: Effect of pressure-level distribution on cycle performance at fixed LN2 precooling conditions. 5.

Uncertainty quantification (Monte Carlo simulations) • Table S6: Regional liquid hydrogen production cost under uncertainties in electricity prices, LN2 prices, SEC variation, foreign-exchange rate, and transport/tax factors (China, United States, European Union; N=100,000). • Table S7: Parametric LH2 cost sensitivity under region-specific electricity and LN2 price scenarios.
