§01 · Pathway scope
Water electrolysis is calibrated. Everything else is reserved.
At launch H₂VALIS calculates production for PEM, AEL and SOEC. The remaining hydrogen production families appear in the workspace as reserved — coefficients not yet calibrated — so the interface does not silently apply electrolyser equations to reforming, gasification, pyrolysis or biological routes.
Calibrated at launch
Proton Exchange Membrane
Fast dynamic response, high current density
Alkaline Electrolysis
Mature, lowest CAPEX at scale
Solid Oxide Electrolyser Cell
High-temperature; requires heat source input
Reserved — not yet calibrated
Interfaces are prepared; calculation stays disabled until source-specific evidence is incorporated.
Steam Methane Reforming
UnavailableAutothermal Reforming
UnavailableCoal / biomass gasification
UnavailableMethane pyrolysis
UnavailableBiological / dark fermentation
UnavailableTransport modes
Shipping is intentionally benchmark-only: one ship is not equal to N trucks — it introduces terminals, carrier conversion, storage, boil-off, voyage time and reconversion boundaries that require separate calibration.
Road (GH₂ trailer)
Distance, fleet utilisation, empty returns
Pipeline
Throughput, pressure-drop, compressor spacing
Rail
Under active calibration
Shipping
Benchmark-only until terminals, carriers and boil-off are calibrated
