BRSupercool Hydrogen Airport Systems Model

SELECT A SYSTEM ELEMENT

Bulk LH₂ storage

The airport buffer between an intermittent supply/logistics chain and minute-by-minute aircraft demand. It drives land, safety separation, boil-off management, resilience and capital intensity.

System leverage points

1 · Demand aggregation
Flight schedule drives storage, delivery frequency, bowser count and liquefier sizing.

2 · Parallel turnaround
Refuelling policy drives stand capacity more than fuel flow alone.

3 · Loss fate
Every kg lost is simultaneously a safety, operating-cost and lifecycle variable.

4 · Topology transition
The critical question is when tanker/bowser stops scaling and pipeline/liquefaction/hydrant becomes better.
