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.
