DOT 49 CFR & ISO 11119-3 Pressure Vessel Rules • Bulk Hydrogen Distribution
Hydrogen Compression & Tube Trailer Logistics Sizer
Size industrial hydrogen compressor stations and over-the-road tube trailer fleets. Model multi-stage reciprocating, hydraulic diaphragm, and ionic liquid compressors boosting electrolyzer output (30 bar) to bulk transit pressures (250 to 500 bar). Compare steel Type I (300 kg H₂) vs. carbon fiber composite Type IV (1,100 kg H₂) payload economics and Levelized Cost of Delivery ($/kg H₂).

📐 Multi-Stage Gas Compression & Ideal Gas Real Correction
• Isentropic Compression Work: W_is (kJ/kg) = [k / (k-1)] * Z_avg * R_specific * T_in * [ (P_out/P_in)^((k-1)/(N*k)) - 1 ] * N_stages
• Hydrogen Properties: k (Cp/Cv) = 1.41 | R_specific = 4.124 kJ/(kg·K) | High-pressure compressibility factor Z > 1.25 at 500 bar
• Connected Power: P_comp (kW) = (Mass_Rate_kg/s * W_is / η_isentropic)
• Delivery Cost: LCOD ($/kg) = (Annual_Compressor_Power + Annual_Trucking_Freight + Annualized_CapEx) / Annual_kg
