Cryogenic Compatibility:
Liquid hydrogen is stored at extremely low temperatures (approximately -253°C or -423°F). The nozzle must be constructed from materials that can withstand these cryogenic conditions without losing structural integrity or performance. Typically, stainless steel or other durable, low-temperature-resistant materials are used.
High Pressure Rating:
Due to the nature of hydrogen refueling, which often occurs at high pressures (up to several hundred bar), the nozzle is designed to handle these pressures safely while ensuring no leaks occur during the transfer process.
Safety Mechanisms:
Hydrogen is a highly flammable gas, and thus the nozzle incorporates advanced safety mechanisms. These include sealing systems to prevent leaks, automatic shut-off valves, and interlocking mechanisms that ensure the nozzle is securely connected before fuel transfer can begin. Safety features like breakaway functionality may also be included to prevent accidents if the refueling hose is accidentally pulled.
Ergonomic Design:
The nozzle is often designed to be lightweight and easy to handle. Ergonomics are particularly important for refueling operations, as it needs to be attached and detached manually from the vehicle or storage tank.
Thermal Insulation:
To minimize heat transfer and keep the hydrogen in its liquid form, the nozzle typically features thermal insulation to maintain the cryogenic temperatures required for the process. This prevents boil-off or evaporation of the liquid hydrogen during the refueling process.
Efficient Sealing:
Proper sealing between the nozzle and the receptacle is critical to prevent hydrogen leakage, which can be hazardous. The design often includes redundant sealing systems to ensure safety during connection and disconnection.
A. Utilize vacuum insulation technology to minimize the temperature rise of the medium.
B. Introduce a hydrogen blow-through function to enhance filling safety.
C. The interlocking design ensures that the operation logic aligns more closely with standard operating practices.Automotive Hydrogen Refueling: The nozzle is used to refuel hydrogen-powered vehicles, such as fuel cell electric vehicles (FCEVs), ensuring a fast and efficient transfer of liquid hydrogen into the vehicle's storage tanks.
Aerospace and Industrial Applications: It is also used in the aerospace sector, where hydrogen is increasingly explored as a clean fuel alternative, as well as in industrial applications requiring liquid hydrogen transfers
