Hydrogen production plant calculator: Green, Blue and Grey.
Compare Green electrolysis, Blue SMR with carbon capture and Grey SMR hydrogen production economics using editable cost, production and sale assumptions.
Green hydrogen production plant inputs
Planning model only. Electricity price, electrolyzer efficiency, water treatment, compression, storage, transport, degradation, financing, carbon certificates and offtake terms can materially change the result.
Method: Green hydrogen cost combines electricity consumption, water treatment, O&M and CAPEX amortization. Blue and Grey models combine feedstock, plant cost, amortization and optional carbon capture.
Inputs used: Currency = INR; Monthly hydrogen production = 10,000 kg; Electricity per kg of hydrogen = 53 kWh/kg; Renewable power rate = 4.5 ₹/kWh; Demineralized water per kg = 9 L/kg; Water and treatment cost = 0.12 ₹/L; Electrolyzer O&M and consumables = 35 ₹/kg; Electrolyzer CAPEX amortization = 80 ₹/kg; Hydrogen selling price = 450 ₹/kg
Assumptions: The result uses the values, units and options shown in the input snapshot.
Scope and warnings: Planning model only. Electricity price, electrolyzer efficiency, water treatment, compression, storage, transport, degradation, financing, carbon certificates and offtake terms can materially change the result. Rounding and excluded real-world terms can make an external result differ.
How this hydrogen production plant calculator: green, blue and grey works
Green hydrogen cost combines electricity consumption, water treatment, O&M and CAPEX amortization. Blue and Grey models combine feedstock, plant cost, amortization and optional carbon capture.
A worked example
At 53 kWh per kg and ₹4.50/kWh renewable power, electricity contributes ₹238.50 per kg before water, O&M and CAPEX.
Does this determine a plant’s real project cost or viability?
No. Confirm equipment performance, energy sourcing, gas price, carbon-capture conditions, water treatment, compression, logistics, finance, incentives and offtake terms for the project.
