Hydrogen Electrolysis Water Demand Calculator
The default 8,423 t H₂/year at 12 L/kg needs 101,076 m³/year; 9 L/kg gives 75,807 m³/year. Estimate daily and yearly water; this is 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.
Estimate process-water demand from hydrogen production and a stated litres-per-kilogram assumption. Site intake and permit requirements are outside this screen.
