Metal hydride storage suits applications where low-pressure operation, compact footprint, and high volumetric density matter more than high-pressure throughput. It supports laboratory instrumentation, pilot systems, backup power, and industrial processes where a lower-pressure alternative to high-pressure cylinders is required.
Metal hydride tanks can also be thermally integrated with fuel cells, utilizing waste heat to drive hydrogen desorption and improve overall system efficiency. The tanks can operate as standalone units or be seamlessly integrated with electrolysers for on-site hydrogen generation and supply.
Solid-state storage for real operating constraints
Alloy design tailored to your duty cycle
High volumetric hydrogen density
Controlled hydrogen delivery at low pressure for enhanced safety and system simplicity
Low-pressure hydrogen charging depending on the selected alloy and configuration
Metal hydrides store hydrogen in solid form by reversibly absorbing H2 into a metal alloy. This enables storage at low pressure with stable and repeatable absorption and desorption cycles near ambient temperature.
The pressure and temperature behaviour is determined by the intrinsic thermodynamic properties of the alloy. These define the equilibrium pressure characteristics of the system and can be tailored through alloy design to match specific operating requirements.

How to choose
FAQ
Metal hydride storage operates at lower pressure and reduces the need to handle very high-pressure cylinders in many applications. It offers a lower-pressure, more compact alternative where high-pressure delivery is not required. Where high-pressure delivery is needed, storage and compression serve different functions.
Hydrogen desorption is an endothermic process, so the delivery rate is influenced by thermal conditions. Ambient heat can contribute to hydrogen release, while external heating can be used to increase the desorption rate when higher flow is required.
Required inlet hydrogen quality: ≥ 99.999 vol%. Allowable contaminants are defined in the technical specifications for each product. Industrial configurations are defined during the project scoping phase.
Yes. Containerised systems provide industrial-scale hydrogen buffering with project-defined capacity and footprint. Capacity and layout are defined around the specific duty cycle and facility constraints.
