Integration of Onboard Hydrogen Storage for Heavy Transport Systems

ULEMCo Ltd and Luxfer Gas Cylinders Ltd formalized a collaboration to engineer and deploy integrated onboard hydrogen storage systems. The technical framework targets heavy-duty transport sectors, including commercial vehicles, rail, marine, and off-road equipment, where high-density energy storage is required.

Target Industries and Application Areas
The application scope encompasses heavy mobility sectors where conventional battery-electric systems lack the necessary energy density or operational payload capacity. Specific technical use cases include the deployment of hydrogen systems in refuse collection vehicles, road sweepers, light goods vehicles, and emergency response units. By substituting or supplementing diesel with hydrogen gas, fleet operators maintain operational range and payload capacities while achieving process stability in route completion times and reducing exhaust emissions. A prior hardware deployment involved a dual-fuel refuse truck operating on a controlled combination of hydrogen and hydrotreated vegetable oil.

Operational Challenges and Partner Roles
The primary industrial challenge in heavy-duty transport involves integrating alternative fuel systems without compromising vehicle weight parameters or continuous operating hours. ULEMCo specializes in hydrogen systems integration and powertrain adaptation, while Luxfer Gas Cylinders manufactures advanced high-pressure gas storage technologies. The cooperation addresses the mechanical complexity of packaging high-pressure gas systems within the strict spatial constraints of existing heavy-duty chassis. Combining cylinder manufacturing scale with vehicle integration expertise provides a standardized approach to onboard energy storage.

System Architecture and Integration Responsibilities
The technical solution consists of high-pressure hydrogen storage cylinders integrated into customized vehicle mounting architectures. Luxfer Gas Cylinders is responsible for the materials engineering and production of the high-pressure vessels, which are designed to contain hydrogen safely under continuous mechanical and thermal stress. ULEMCo manages the systems integration, encompassing the design of fuel delivery architectures, pressure regulation modules, and safety control systems that interface directly with the vehicle's powertrain and digital infrastructure. This division of engineering ensures that the storage parameters meet rigorous safety standards while functioning reliably within the vehicle's broader energy ecosystem.

Implementation and Physical Integration
The integrated storage solutions are engineered for both vehicle retrofits and new equipment manufacturing. During deployment, the hydrogen storage units are integrated into the existing physical frameworks of heavy-duty chassis, requiring detailed structural analysis and the secure routing of high-pressure lines to the combustion or fuel cell systems. Both partners support the engineering phases, from initial prototype design to full-scale commercial deployment, ensuring that the hardware integrates into commercial fleets without requiring extensive modifications to the base vehicle platforms.

Expected Impact and Strategic Deployment
The collaboration provides scalable hydrogen storage configurations that simplify the manufacturing and retrofit processes for heavy-duty fleets. By standardizing the integration of onboard hydrogen cylinders, the partnership lowers the engineering threshold for operators transitioning away from fossil fuels, ensuring predictable refueling mechanisms and structural reliability. Regarding the strategic scaling of this technology, Amanda Lyne, Managing Director of ULEMCo, indicated that aligning the engineering capabilities of both organizations strengthens the capacity to deliver safe, integrated hydrogen systems that facilitate the transition to zero-emission transport infrastructure.
