Tech Talk - Hydrogen Tank Systems - H2 refueling - Fuel Cell Technology Explained - Hyfindr Andreas

Learn about hydrogen tank systems, their components, and applications in this Hyfindr Tech Talk. In this conversation, Steven welcomes Jan, who has expertise in hydrogen storage and systems. They discuss tank systems and their components, such as the on-tank valve (OTV) and thermal pressure relief device (TPRD). Jan explains that tank systems consist of tanks, valves, and a gas handling unit, which regulate the pressure and deliver hydrogen to the fuel cell. They also discuss different applications of tank systems in vehicles, buses, and marine vessels. Jan mentions refueling procedures and the need to prevent overheating during the process. Overall, they explore the technical aspects and configurations of different tank tank systems technologies (compresses versus cryo (Liquid) versus cryo compressed (a mix of both) for various purposes.

Executive Summary of Tech Talk Script:
During this Hyfindr Tech Talks, Steven and Jan, discuss various aspects of tank systems for hydrogen storage and usage. The basic component of a tank system is the on-tank valve (OTV), which allows for the disconnection of hydrogen supply, opening and closing of the hydrogen circuit, and includes safety features such as pressure and temperature sensors. The tank system also includes a thermal pressure relief device (TPRD) for longer tanks, ensuring the tank is emptied in case of a fire before it is destroyed.
Illustration of different applications of tank systems, such as in passenger cars, mid-sized buses, trucks, and even maritime vessels. For example, passenger cars typically require 4-6 kilograms of hydrogen, while 40-ton trucks may need around 40-60 kilograms. An exciting project involving an electric push boat powered solely by fuel cells and batteries carry 700 kilograms of hydrogen in specially designed cartridges, providing a fully decarbonized alternative to traditional diesel engines.
Typically, tanks are placed behind the cabin of a truck, with batteries positioned upfront to balance the vehicle's weight. However, alternative configurations are such as placing tanks between the wheels, which is more common in the US due to regulations allowing longer trucks.
There are ISO standards for refueling procedures, and currently, refueling up to 10 kilograms of hydrogen is well regulated. For larger quantities, the procedures are still being validated. A challenge during refueling, which is the heating of hydrogen that occurs when it is compressed. To prevent overheating, hydrogen is cooled down up to -40°C during the refueling process for 700-bar applications.
