Methodology (at a glance)

We compute annual hydrogen output from nameplate capacity, consumption and utilisation. Annualised CAPEX uses a capital recovery factor (CRF) over asset lifetime at your discount rate. Annual costs include electricity, water, fixed/variable O&M and stack replacement amortised over its interval. LCOH equals total annual cost divided by annual hydrogen.

LCOH FAQs

Answers to common questions about levelised cost of hydrogen.

What is LCOH?

Levelised Cost of Hydrogen is the discounted lifetime cost per kilogram of hydrogen produced, combining capital recovery and operating costs.

Which inputs drive LCOH?

Utilisation, electricity price, electrolyser CAPEX, efficiency (kWh/kg), stack life and O&M typically dominate sensitivity.

Does it cover PEM and alkaline?

Yes—configure consumption (kWh/kg), CAPEX/kW, stack cost and life to represent PEM, alkaline or SOEC pathways.
