What actually makes up a hydrogen tank system—and how do you refuel safely at 350/700 bar?

In this episode of Hyfindr Tech Talks, Jan Andreas (Argo-Anleg) joins Steven Oji to break down complete hydrogen storage systems for vehicles and vessels. From the on-tank valve (OTV) and thermal pressure relief device (TPRD) to the integrated gas handling unit (GHU) with sensors, solenoid valves, and pressure regulation, Jan explains how systems deliver hydrogen at the right pressure to fuel cells or H₂ ICEs. They also cover refueling protocols, IR communication between vehicle and dispenser, temperature management (pre-cooling to ~–40 °C and tank 65 °C limits), and real-world deployments—from buses and 40-ton trucks to swappable MEGC cartridges on a hydrogen push boat.

You’ll learn about:

System boundaries: refueling interface, tanks with OTV/TPRD, GHU block, outlet to fuel cell/engine

Pressure & regulation: stepping down 350/700 bar to stack/application requirements

Sensing & control: pressure/temperature sensing, solenoids, communications (IR handshake)

Refueling engineering: ramp control, flow rates, hot-spot formation, pre-cooling to manage heat

Applications & sizing: ~5–6 kg (passenger cars), ~20–30 kg (buses/medium trucks), ~40–60 kg (heavy trucks), hundreds of kg for maritime with swappable containers

LH₂ vs compressed H₂: cryogenic challenges (≈–253 °C), boil-off, and why compressed storage often wins on complexity

Ideal for vehicle integrators, storage engineers, and hydrogen infrastructure teams designing safe, efficient H₂ systems end-to-end.
