A patent filed by L’Air Liquide, “Device for Storing and Supplying Cryogenic Fluid,” proposes a state-of-the-art technology designed explicitly for storing and supplying liquefied hydrogen.

Features and Improvements

The patented device presents several unique features that distinguish it from existing technologies in the field. It includes a cryogenic storage tank for liquefied hydrogen, a bleed-off circuit, and a sophisticated system for pressurizing the tank. This system consists of a pressurizing duct connected to the upper and lower portions of the storage tank, a vaporizing heat exchanger, and several valves that regulate liquid flow.

One significant improvement is the ability of the device to bleed off a predetermined volume of fluid, store it in the vaporizing heat exchanger, and reinject it into the tank once it reaches specified temperature and pressure conditions. This ensures optimal pressurization and efficient utilization of stored hydrogen. Furthermore, the pressurizing duct includes a member that limits the flow rate and pressure of the reinjected fluid, enhancing the safety and stability of the system.

Potential Applications

This technology has numerous potential applications. It is particularly suited for onboard storage systems in vehicles running on hydrogen fuel, such as fuel cell electric vehicles (FCEVs). It can also be used in industrial applications where large volumes of hydrogen are required, such as in the chemical industry or for large-scale hydrogen fueling stations.

Market Impact

The introduction of this advanced storage device could significantly impact the hydrogen market. Providing a safer, more efficient way to store and supply liquefied hydrogen could accelerate the adoption of hydrogen as a clean energy source. This, in turn, could expand the market for hydrogen-powered vehicles and industrial applications, driving growth and innovation within the sector.

Technical Specifications

According to the patent, the device includes:
– A cryogenic storage tank for liquefied hydrogen.
– A bleed-off circuit and pressurizing duct connected to the tank.
– A vaporizing heat exchanger for fluid storage and temperature regulation.
– A set of valves to control fluid flow.
– A system configured to bleed off, store, and reinject fluid at predetermined conditions.
– A member to limit the flow rate and pressure of the reinjected fluid.

Key Takeaways

The patented device by L’Air Liquide represents a significant innovation in hydrogen storage and supply technology. Its unique features ensure efficient pressurization and utilization of liquefied hydrogen, offering improvements over current market solutions. With potential applications in the transportation and industrial sectors, the device is poised to substantially impact the hydrogen market, promoting broader adoption and advancing the use of hydrogen as a sustainable energy source.
