What this tool does
Provides a screening estimate of hydrogen storage quantity, indicative vessel footprint, compressor implications, and early CAPEX ranges across storage options.
Hydrogen storage sizing & CAPEX
Estimate compressed storage volume, compressor duty, and benchmark CAPEX against other storage approaches.
When to use it
Use it for option comparison, preliminary storage philosophy decisions, and early plot-space conversations. Do not use it as a substitute for pressure-vessel design, hazard review, or supplier quotations.
Key assumptions
- Storage sizing uses simplified density and containment assumptions suitable for early-stage concept work.
- CAPEX ranges are heuristic screening allowances, not bankable vendor pricing.
- Compression and storage interactions are directional and should be validated against the final operating philosophy.
- Default values are intended to accelerate screening and should be replaced before FEED or procurement.
