Indian Hydrogen Refuelling Station (HRS) MEP — NFPA 2 + ISO 19880 + SAE J2601 + PESO
An Indian 500 kg/day H2 Refuelling Station demands ₹285 Cr MEP capex with bulk storage + 4-stage compression + cascade + -40°C pre-cooling + 350+700 bar dispensers + NFPA 2 safety + solar hybrid. NFPA 2 + ISO 19880 + SAE J2601 + IEC 62282 + IS 12379 + PESO govern. LCOH ₹280-580/kg by 2030. Three failures: SAE J2601 -40°C pre-cooling under-spec causing tank overheat > 85°C, NFPA 2 separation < 6-15 m in compact urban retrofit, cylinder changeover without N2 purge creating flammable mixture.
Indian hydrogen refuelling station (HRS) framework
India H2 mobility — Reliance + Adani + IOCL + BPCL + L&T + NTPC announcing HRS at NH highways + GIFT City + industrial clusters. By 2030 target 100+ HRS aligned with green H2 production. Standards stack — NFPA 2:2023 (Hydrogen Technologies) + ISO 19880 (Gaseous Hydrogen Fuelling Stations) + ISO 17268 + SAE J2601 (fuelling protocol) + IEC 62282 (fuel cells) + IS 12379 + PESO Gas Cylinder Rules 2016 + Bharat Stage Norms for H2 vehicles + MoRTH H2 vehicle Type approval.

Three Indian HRS MEP failures
- SAE J2601 -40°C pre-cooling under-spec — H2 fast-fill at 700 bar without -40°C pre-cooling violates SAE J2601 + heats vehicle tank > 85°C limit. Specify dedicated chiller per dispenser + brazed-plate HX.
- NFPA 2 separation distances ignored — H2 cascade + dispenser require 6-15 m separation from buildings + property line + vent stack 15 m height. Indian compact site designs (especially urban retrofit) violate.
- Cylinder + tube-trailer changeover without N2 purge — H2 atmosphere mixing with air at changeover creates 4-75 % flammable range. PESO + NFPA 2 require N2 purge before connect. Indian operators sometimes skip purge to save time.
