Method and Apparatus for Catalytic Release of a Gas from a Carrier Material

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a method and apparatus for catalytically releasing a gas—especially hydrogen—from a carrier material, typically a liquid organic hydrogen carrier (LOHC). The main innovation is to periodically move or agitate the catalyst particles inside the reactor to re-activate them and sustain high catalytic activity. This mechanical or fluidic movement prevents deactivation caused by blockage of pores in the catalyst by the carrier fluid, ensuring continuous and efficient gas release.

Use CasesContent extracted from patent full text and abstract with AI.

• On-demand hydrogen release from LOHCs for fuel cell vehicles (cars, trucks, trains, ships).
• Stationary or mobile hydrogen supply systems for industry or power generation.
• Backup hydrogen production units for remote or off-grid sites.
• Portable or modular hydrogen release units for emergency or temporary operations.
• Integration into renewable energy storage systems, leveraging LOHCs for hydrogen transport and later release.

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly extends catalyst lifetime and maintains high efficiency through active reactivation.
• Enables higher power density and faster hydrogen release, essential for mobility and industrial uses.
• Supports fully automated and sensor-controlled operation, reducing maintenance.
• Improves safety and system robustness by reducing risk of catalyst deactivation blockages.
• Compatible with existing LOHC and catalyst technologies, facilitating integration into current hydrogen infrastructure.
• Enables compact and energy-efficient system designs suitable for vehicles and transport applications.
