CAPEX Tool — BuckleBridge

Build a bankable configuration

Select your preferred electrolyser technology, target capacity and storage profile. The tool estimates high-level CAPEX with a configurable breakdown and gives indicative sizing guidance.

Plant parameters

Plant capacity (MW) i

Electrolyser technology i

Module size (MW per skid) i

Target availability (% runtime) i

Storage & compression

Storage autonomy (hours) i

Storage medium i

Export pressure (bar) i

Include downstream compressor (disable if electrolyser provides required pressure)

General CAPEX factors

Balance-of-plant factor (% of electrolyser CAPEX) i

Grid & connection allowance (MEUR) i

Contingency (% of subtotal) i

Include buildings & civils allowance (default 0.8 MEUR per 10 MW)

Additional CAPEX items

Engineering & design (% of electrolyser + BOP) i

Installation & erection (% of equipment) i

Freight & logistics (% of equipment) i

Land acquisition (MEUR) i

Permitting & environmental (MEUR) i

Commissioning & start-up (MEUR) i

Owner's costs (% of subtotal) i

Assumptions are indicative. For investment cases, validate with vendor quotes and site-specific estimates.
