How to Use This Calculator
  1. Enter Electricity Price ($/kWh), Electrolyzer CAPEX ($/kW), and Electrolyzer Lifetime (years).
  2. Set Capacity Factor (%) and Water Cost ($/liter).
  3. Review the LCOH ($/kg H₂) ($) result.
  4. Use Electricity Cost per kg ($) and CAPEX per kg ($) to inform your decision.
  5. Use the chart to visualize the results and explore different scenarios by adjusting inputs.

How the result changes with Electricity Price ($/kWh)

Electricity Price ($/kWh)LCOH ($/kg H₂)
$0.06$3.87
$0.18$9.68
$0.33$16.73
$0.45$22.53

What each input means

Electricity Price ($/kWh)
Cost of renewable electricity. Solar/wind PPAs: $0.02-0.08/kWh.
Electrolyzer CAPEX ($/kW)
Capital cost per kW of electrolyzer capacity. PEM: $1000-1800, Alkaline: $500-1200.
Electrolyzer Lifetime (years)
Expected operational lifetime including stack replacements.
Capacity Factor (%)
Percentage of time the electrolyzer operates. Grid: 90%+, Solar-only: 20-30%.
Water Cost ($/liter)
Cost of deionized water per liter. Typically $0.001-0.005/L.

What each result means

LCOH ($/kg H₂)
Levelized cost of hydrogen per kilogram.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Electricity Price ($/kWh) = 0.05, Electrolyzer CAPEX ($/kW) = 1200, Electrolyzer Lifetime (years) = 20, Capacity Factor (%) = 50 = 5 input(s) provided
  2. Calculate LCOH
    LCOH
    3.44 = $3.44
  3. Calculate Electricity Cost per kg
    Electricity Cost per kg
    2.38 = $2.38
  4. Calculate CAPEX per kg
    CAPEX per kg
    0.65 = $0.65
