Advances in conformable tank technology have resulted in opportunities to harness and deploy hydrogen energy in a variety of operational environments. Various use cases are described, and the benefits of these unique storage systems in vehicular, stationary, and bulk storage applications are illustrated. The impressive scalability of conformable hydrogen tank production is also explained, as it relates to the cost effective and broad application of these storage systems.
Tarek Abdel-Baset, Forvia's chief engineer for hydrogen storage systems, has two decades of experience in alt-fuel transporation development, with all the ups and downs that entails. So he was a good person for SAE Media to ask about the industry vibe at the 2025 Advanced Clean Transportation Expo in Anaheim.
Since the 1860 Hippomobile, hydrogen has been a part of powered mobility. Today, most hydrogen storage applications use cylindrical tanks, but other solutions are available. At a recent Bosch-sponsored event, SAE Media noted Linamar's Flexform conformable storage, which the company says uses the same or less material for a given storage volume while delivering anywhere from 5-25% more volumetric efficiency than conventional cylindrical tanks within that volume. “We see space as a regular bounding box where all you're losing is this area around the corners, closer to five to 10% [loss]. Where Flexform really shines and where the value proposition really is, is irregular spaces, such as between frame rails,” said representatives from the Linamar engineering team.
In order to give full play to the economic and environmental advantages of liquid organic hydrogen carrier(LOHC) technology in hydrogen storage and transportation as well as its technological advantages as a hydrogen source for hydrogen refueling station(HRS) supply, it promotes the change of hydrogen supply method in HRSs and facilitates its technological landing in the terminal of HRSs. In this paper, combining the current commercialization status of organic liquid technology and the current construction status of HRS in China, we establish a traditional long-tube trailer HRS model through Matlab Simulink, carry out modification on the existing process, maximize the use of the original equipment, and introduce the hydrogen production end of the station with organic liquid as an auxiliary hydrogen source. Research and design of the two hydrogen sources of gas extraction strategy and the station control strategy and the formation of Stateflow language model, to realize the verification

Cylindrical tanks no longer are the only solution for storing high-pressure hydrogen gas. The future is looking decidedly square - and better for vehicle range and packaging. Experts from Forvia explain. Until recently, there was only one practical solution for storing gaseous hydrogen for onboard vehicle use: the cylindrical storage tank. Spiral-wound, carbon fiber cylinders are the proven form factor for reliable containment of 350-bar (5000-psi) and more commonly, 700-bar (10,000-psi) hydrogen used in the latest fuel-cell electric and hydrogen-fueled IC-engine vehicles. Faurecia and Symbio, the hydrogen-technologies joint-venture with partner Michelin, are in the process of changing the cylindrical-tank paradigm with a new approach that looks downright…square. “This hydrogen storage system is our modular, conformable, 700-bar tank,” Rob Steele, product line manager at Faurecia, part of the Forvia group, told SAE Media while viewing a concept ‘skateboard’ chassis at the 2023
While several commercial vehicle OEMs, including Tesla and Nikola, are in the latter phase of testing battery-electric semi-tractors on the road, action in the hydrogen space continues to grow as it relates to transport vehicles. A few recent product introductions and partnership arrangements are detailed below.

ABSTRACT This paper summarizes development and demonstration of F-24/JP-8-fueled Fuel-Cell Electric-Vehicle that offers silent-mobility, silent-watch, and export-power. The prototype electric vehicle was fueled with MIL-SPEC F-24/JP-8. It can potentially be operated with other logistic fuels and does not require onboard hydrogen storage. An onboard fuel reformer with integrated sulfur trap was used for processing MIL-SPEC F-24/JP-8. The 10-kW electric (kWe) generator included a solid oxide fuel cell and balance of plant components (oxidizer, pumps, blowers, sensors, power and control electronics). It was hybridized with a rechargeable battery for startup, peak loads, and load following. Water neutrality and silent operation (i.e., ~60 dBA at 1-meter) was confirmed. The power produced was sufficient for vehicle propulsion and export power. Both 28-32 VDC and 110 VAC for charging batteries and supporting external load demands were available onboard. Initial off-road demonstrations were
Electrolytic hydrogen production equipment has numerous hydrogen pipelines and high-pressure hydrogen storage tanks which may leak hydrogen which can lead to explosions causing damage to the nearby personnel and equipment. The present work modeled hydrogen explosions in a skid-mounted electrolytic hydrogen production unit. The model was first used to predict the area affected by an explosion without protective walls. The effects of protective walls on the flame and overpressure were then studied by modeling explosions with various protective walls at various distances from the opening on the side of the unit. The results show that the protective walls effectively reduced the damage behind the wall. However, the reflected shock waves may cause secondary damage in front of the wall if the protective wall is too close to the opening. Moreover, the protective wall blocks the hydrogen diffusion which increases the flammable gas mass. The present work can guide protective wall design and
ZeroAvia’s journey into the world of the hydrogen powertrain began with a mission to decarbonize one of the most challenging sectors in existence due to the complexities in recreating the synthesis of chain reactions that aircraft require to fly securely with hydrogen fueling. Currently, the balance of engine-triggered events that power, heat, pressurize, and so forth is not necessarily the result of the high-efficiency performance of fossil fuels. Yet, aircraft use engine inefficiencies to fill other needs such as thermal management. One of the most significant challenges in designing an effective hydrogen powertrain system is keeping the aircraft capabilities intact by using efficient and non-efficient fossil-fuel turbine engine performance metrics as a benchmarking tool for peak hydrogen performance.
This paper describes the high-pressure hydrogen storage system developed for new FCV. With the aim of further popularizing FCVs, this development succeeded in improving the performance of the system and reducing costs. This new storage system consists of multiple tanks of different sizes, which were optimized to store the necessary amount of hydrogen without sacrificing the interior space of the vehicle. The new tanks achieved one of the highest volume efficiencies in the world by adopting high-strength carbon fiber, developed in conjunction with the carbon fiber manufacturer, and by optimizing the layered construction design which allowed the amount of carbon fiber to be reduced. To increase the amount of available hydrogen, the longer high pressure tanks were mounted under the vehicle floor unlike the previous model. This was accomplished by the following two measures: First, individual design and manufacturing measures for the tanks were adopted. The liner shape was optimized to
