#19 – Hyfindr Tech Talks – Hydrogen Tank Systems & Refueling | Jan Andreas – Argo-Anleg

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:<ul><li>System boundaries: refueling interface, tanks with OTV/TPRD, GHU block, outlet to fuel cell/engine</li><li>Pressure & regulation: stepping down 350/700 bar to stack/application requirements</li><li>Sensing & control: pressure/temperature sensing, solenoids, communications (IR handshake)</li><li>Refueling engineering: ramp control, flow rates, hot-spot formation, pre-cooling to manage heat</li><li>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</li><li>LH₂ vs compressed H₂: cryogenic challenges (≈–253 °C), boil-off, and why compressed storage often wins on complexity</li></ul>Ideal for vehicle integrators, storage engineers, and hydrogen infrastructure teams designing safe, efficient H₂ systems end-to-end.Explore more at <a href="https://hyfindr.com/en/" target="_blank" rel="noopener noreferer">Hyfindr.com</a>

#18 – Hyfindr Tech Talks – Manufacturing Metallic Bipolar Plates at Scale | Fabian Kapp – Gräbener

How do you manufacture fuel-cell bipolar plates with high precision, high yield, and production-scale efficiency?In this episode of Hyfindr Tech Talks, Fabian Kapp (Gräbener) joins Steven Oji to walk through an end-to-end bipolar plate manufacturing line—from coil to stack-ready plate. Fabian explains hydroforming (up to ~2,500+ bar), precision laser cutting & welding, proprietary straightening for ultra-flat plates, and why cleaning, leak testing, and sealing are critical for quality and cost. He also shares practical lessons on OEE, staffing, and how to reduce scrap by controlling welding and base-material quality.You’ll learn about:<ul><li>Process flow: decoiling → hydroforming → cleaning → separation → laser cutting → laser welding → straightening → final clean → leak test → sealing → stacking</li><li>Hydroforming details: pressure ranges, flexibility across materials/thicknesses, low tooling cost</li><li>Laser operations: edge quality, port accuracy, 3D features, nitrogen assist</li><li>Welding quality: fixturing/clamping, stitch seams, leak-tight designs around ports/fields</li><li>Flatness & yield: straightening for stackability, scrap reduction, optical inspection</li><li>Production reality: leak testing (pressure-drop/helium), staffing, maintenance windows, and OEE best practices</li></ul>Ideal for manufacturing engineers, operations leaders, and stack designers scaling fuel-cell production lines.Explore more at <a href="https://hyfindr.com/en/" target="_blank" rel="noopener noreferer">Hyfindr.com</a>

#17 – Hyfindr Tech Talks – Hydrogen Pressure Relief Valves & Safety Engineering | Olaf Schulenberg – Goetze KG

How do hydrogen pressure relief valves ensure safety across fuel cell and storage systems?In this episode of Hyfindr Tech Talks, Olaf Schulenberg (Goetze KG) joins Steven Oji to explain the engineering behind spring-loaded hydrogen pressure relief valves — a critical component for ensuring safety in electrolyzers, storage tanks, and liquid hydrogen systems.Olaf breaks down how these valves regulate excess pressure, their internal mechanics, and the importance of certification, testing, and temperature resilience in hydrogen applications. The discussion highlights how robust valve design and monitoring systems prevent failures and maintain safe operating conditions across diverse hydrogen environments.You’ll learn about:<ul><li>How spring-loaded pressure relief valves function in hydrogen systems</li><li>Safety principles and design features ensuring pressure control</li><li>Testing & certification requirements for cryogenic and high-pressure use</li><li>Applications in electrolyzers, storage systems, and LH₂ transport</li><li>Maintenance and monitoring best practices for long-term reliability</li></ul>Perfect for engineers, safety experts, and hydrogen professionals focused on system integrity, certification, and pressure management in the hydrogen economy.Explore more at <a href="https://hyfindr.com/en/">⁠Hyfindr.com</a>
