About the Hydrogen Production Calculator
Hydrogen production by electrolysis is the foundation of the hydrogen economy.
Production depends on electricity input and electrolysis efficiency.
Formula
Hydrogen = Electricity × Efficiency / 33.3
- H
- — Hydrogen Production (kg)
- E
- — Electricity (kWh)
- Eff
- — Electrolysis Efficiency
How to use this calculator
- 1
Enter electricity
Electricity input in kWh.
- 2
Enter efficiency
Electrolysis efficiency percentage.
Example calculations
Green hydrogen production
An electrolyzer uses 1,000 MWh with 75% efficiency.
Hydrogen = 1,000,000 × 0.75 / 33.3 = 22,523 kg.
- Hydrogen production:
- 22,523 kg
- Efficiency:
- 75%
- Energy consumption:
- 44.4 kWh/kg
The electrolyzer produces 22,523 kg of hydrogen from 1,000 MWh.
Interpreting your results
Hydrogen production is the foundation of the hydrogen economy.
Efficiency improvements will be key to hydrogen economics.
