Hydrogen production routes with NeqSim - SMR, ATR, POX, WGS, PSA, CO2 capture, electrolysis (PEM/Alkaline/SOEC/AEM), ammonia cracking, blue/green H2 flowsheets and plant cost. USE WHEN: modeling reformers, syngas generators, shift reactors, PSA, H2 drying/compression/export, electrolyzer I-V curves, para/ortho conversion or catalyst deactivation. Covers ReformerFurnace, WaterGasShiftReactor, BlueHydrogenPlantBuilder, PSACascade, Electrolyzer.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Hydrogen Production with NeqSim Guide for modeling hydrogen production routes — steam methane reforming (SMR), autothermal reforming (ATR), partial oxidation (POX), PSA purification (blue H2), and water electrolysis (green/pink H2). Companion to `neqsim-ccs-hydrogen` (transport/storage/blending) and `neqsim-reaction-engineering` (reformer kinetics). ## When to Use This Skill - SMR fired reformer, ATR, and POX plant flowsheets with WGS + PSA - Oxygen-to-carbon and steam-to-carbon envelope screening - Reformer furnace heat-balance and tube-wall checks - POX/ATR quench, refractory, soot-risk, and H2/CO screening - PSA bed sizing and purity/recovery analysis - Electrolyzer technology selection (PEM vs Alkaline vs SOEC vs AEM) - Stack voltage modeling from current density (I-V curves) - Specific energy consumption (kWh/kg H₂) - Hydrogen plant CAPEX estimation - Cryogenic para/ortho H₂ conversion screening - Catalyst activity decay for SMR/WGS/ammonia cracking studies - Blue vs green H₂ techno-economic comparison ## Applicable Standards | Standard | Scope | |---|---| | ISO 14687 | Hydrogen fuel quality (PEM-FC grade ≥ 99.97% H₂) | …

How to install
mdr add equinor/neqsim/neqsim-hydrogen-production@sha256:7c1330f937e3efddThe line at the top of this page pins the label git:20261028.a160d27, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
