Hydrogen LH₂ Tank Systems
Cryogenic storage for maximum range, fast refueling, and zero-emission transport
SAG is a recognized technology leader developing advanced cryogenic storage solutions for liquid hydrogen (LH₂). In collaboration with OEMs and hydrogen initiatives, we are pioneering efficient LH₂ tank systems for heavy-duty trucks, enabling higher range, faster refueling, and enhanced payload compared to conventional compressed hydrogen tanks
Applications
- Air suspension systems – reservoirs mounted directly on air-sprung struts.
- Turbocharger units – providing additional air volume as needed.
- Engine charging in luxury/upper mid-range vehicles – optimizing performance and comfort
Technical data
- Operating pressure: Approx. 20 bar
- Manufacturing method: Rheocasting for enabling near-net-shape geometries and superior material performance
- Material options: Aluminium and stainless steel, depending on application requirements
Advantages
Advantages of fuel and oil tanks for truck OEMs
Maximum efficiency
Up to 1,000 km range, improved payload capacity, and more transport volume.
Higher storage capacity
Over 40 % increase compared to 700 bar and 60 % compared to 350 bar compressed hydrogen tanks.
Fast refueling
Cryogenic LH₂ refueling is significantly quicker than gaseous hydrogen refills.
Versatile use
Suitable for both fuel cell (FC) and hydrogen internal combustion engine (ICE) vehicles.
Safe and robust
Thermos-flask construction with vacuum insulation ensures long hold times and minimal boil-off.
Sustainable mobility
Enabler for zero-emission heavy-duty transport and large-scale hydrogen adoption.
