Tech Talk - Hydrogen On Tank Valves - Hydrogen Components Testing Machine - Hyfindr Harhoff
In this Hyfindr Tech Talk, we discuss hydrogen tank valves with Burkhard Harhoff, Technical Director New Business at Poppe + Potthoff. We explore the features of a newly certified on-tank valve for 700-bar hydrogen systems. Burkhard explains the valve's safety features, such as thermal pressure relief (TPRD) mechanisms, and the importance of flow capacity (Kv value) for refueling and emptying tanks quickly. We also touch on regulatory challenges across markets and innovations to increase valve efficiency, robustness, and cost-effectiveness for broader hydrogen adoption.

Executive Summary of Tech Talk Script:
In this Hyfindr Tech Talk, Burkhard Harhoff, Technical Director New Business at Poppe + Potthoff, discusses innovations in high-pressure on-tank valves for hydrogen storage systems. The conversation centers on the company’s newly certified 700-bar on-tank valve, emphasizing safety, durability, and efficiency in hydrogen applications. Burkhard explains how these valves are meticulously designed to withstand extreme conditions, including thermal pressure regulation through a TPRD (Thermal Pressure Relief Device), which activates when temperatures exceed 110°C, safely venting hydrogen to prevent damage.
We explore the significance of Kv values, which quantify flow capacity and impact the speed of tank refueling and defueling, a key factor in making hydrogen vehicles practical and user-friendly. Filters are essential to maintain clean hydrogen flow, preventing valve blockages and enhancing longevity. For precise temperature control, the valve integrates sensors and multiple flow pathways, managing the unique thermal properties of hydrogen, which heats when expanding, posing risks to tank materials.
Burkhard and Steven touch on the broader landscape of hydrogen technology, noting the lack of unified international standards for hydrogen components. Various regions, such as the U.S., China, and Korea, follow different regulations, which complicates production and adds to costs. Standardization could reduce these costs and streamline safety protocols globally. Poppe + Potthoff addresses these challenges with their innovation lab, where specialized test machines simulate high-pressure conditions, verifying product durability under extreme and fluctuating pressures.
Looking forward, Burkhard notes that continued advancements in valve design will focus on combining multiple functions into single, compact components, optimizing safety and efficiency. He hints at potential architectural shifts, such as combining multiple tanks with fewer, more integrated valve systems to simplify the hydrogen infrastructure. With these innovations, Poppe + Potthoff aims to push the hydrogen industry toward safer, more affordable, and efficient solutions, preparing for wider adoption of hydrogen fuel technology.

How to get the liscence
@@nurmuhammadnordin9596 you can contact Air Liquide via www.hyfindr.com; go to the product of interest of the brand Axane and make an inquiry. Hope that helps.
6:50 the graph legend is wrong!
What the heck? The PEM splits water into 3 parts (oxygen, hydrogen proton, and hydrogen electron) then routes them in 3 separate directions only to join back the hydrogen components on the other side? (1) How does it do that? (2) Why split the electron off from the proton? (3) If one of the byproducts is hydrogen then can't this system just be primed with a minimal amount of water and then keep reusing the same hydrogen?
What do you mean by reusing hydrogen? Hydrogen is the product you want to obtain afterwards. The point of the electrolyzer is not to use the energy to turn on a bulb, for example; it is to produce hydrogen..
@@MsRosHD This video was not clear and seemed like the fuel cell had a hydrogen byproduct which sounded wrong and like a perpetual motion machine... now I see they were talking about the electrolyzer and that the membrane is used for both the electrolyzer and fuel cell. There is another interview/video of a different guy from hyfindr which is more clear.
Would a billion of these fuel cells running at once change the balance of the various gases containing oxygen? (Oxygen, Ozone, Carbon dioxide, etc)

Hello Tim and Steven, Thanks for sharing this wonderful informative video. I am a little confused with the fuel cell layout displayed in the 12th minute. In a fuel cell reactants, hydrogen gas flows through the anode and oxygen flows through the cathode. Here in that slide the reactions are represented differently. Is that a mistake?
They mixed up electrolyzers with fuel cells, in my opinion. I googled the image, and the reactions weren't displayed, so they added them but did it wrong
It’s the proton that goes through the membrane not hydrogen. Hydrogen is formed at the cathode side when proton and electron reacts together on catalyst of cathode side. Water splits in to oxygen and protons and electrons at the anode side. Thank you 😊

Could lower flow, greater in quantity of AEM-s compensate for fever PEM groups?
Hi, thank you for your question. Higher flow rates could result in better electrochemical properties while lower flow rates could increase the lifetime of the membrane. This would apply to both PEM and AEM. With precious/costly/rare metals being the limiting factor for PEM technology, AEM technology, which uses more common metals and catalysts, is where we see the future of electrolyzer technology headed. Hope that helps! - Tim
Thank you.
Can’t the same membrane work for compression? And what would be the pressure output of compression? Lesser or bigger than 1000psig.
Hi, thank you for your question. The PEM or AEM membranes may be used for compression depending on the set up and desired effect. As for pressure, our membranes with the thicker width's have been tested to withstand up to 35 bar or more which is equivalent to 507 PSI or more. Hope that helps! - Tim
Membranes are also used in electrochemical compressors for hydrogen. The efficient compression of hydrogen is important due to their low volumetric energy density. Electrochemical compressors are efficient compressors and purifiers of H2
So annoying and rude! Why the constant interruptions? If you're going to invite a guest to talk about something, allow him the courtesy to speak!
