Hydrogen Electrolysis Water Demand Calculator

Estimate yearly and daily process water from hydrogen output and L/kg use. Shows 9 L/kg stoichiometric and your chosen-ratio result; not a permit.

Enter annual hydrogen output and a water-use ratio to estimate yearly and daily process water, alongside the 9 L/kg stoichiometric result. This is a first-pass calculation, not a permit. Derive production from power assumptions in electrolyzer sizing.
