A liquid hydrogen (LH2) refueling nozzle is a specialized component designed for safely and efficiently transferring liquid hydrogen during refueling processes, particularly in hydrogen-powered vehicles or refueling stations for aerospace, automotive, and other industries that utilize hydrogen as a fuel source. 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.
