About this app

Perform all your H₂ calculations using the hydrogen thermodynamic matrix:

Calculator: Enter the tank volume, target pressure, and temperature to get the corresponding hydrogen mass.

Transfer: Input station and vehicle data to determine the transferred quantity, transfer feasibility, or balance pressure.

Conversions: Instantly convert units when they don’t match.

History: View your most recent calculations at a glance.

**NEW**: Save your vehicles for quick access in dropdown menus — no need to re-enter the same data every time!
