As much as liquid hydrogen is really beneficial to decarbonizing the world, the dangers associated with it must not go unnoticed. Here are several safety measures to keep in mind when handling liquid hydrogen:
1. Proper Storage Design
- Cryogenic Tank Specifications:
Liquid hydrogen must be stored in specially designed cryogenic tanks that can withstand extremely low temperatures (around -253°C). These tanks are typically made from materials that resist brittleness and thermal cycling stresses, such as stainless steel or aluminum alloys. - Insulation:
Effective insulation is crucial to maintain the cryogenic temperatures necessary for liquid hydrogen storage. Insulation minimizes heat transfer, preventing boil-off (the conversion of liquid hydrogen back to gas) and maintaining safety.
2. Pressure Relief Systems
- Pressure Relief Devices:
Tanks must be equipped with pressure relief devices to prevent over-pressurization due to liquid boil-off or other process upsets. These devices allow excess pressure to vent safely, reducing the risk of tank rupture. - Venting Systems:
Safety relief devices should be vented unobstructed to the outdoors, ideally at a height that prevents hydrogen from accumulating near the ground, where it could pose an explosion risk.
3. Transportation Safety
- Specialized Transport Containers:
Liquid hydrogen is transported in specialized tankers designed to maintain cryogenic temperatures and prevent leaks. These containers must be equipped with safety features such as pressure relief valves and robust insulation. - Grounding and Bonding:
Mobile liquid hydrogen supply units must be grounded to prevent static electricity buildup, which could ignite hydrogen gas. Proper bonding ensures that all components are at the same electrical potential, reducing the risk of sparks.
4. Ventilation and Dispersion
- Adequate Ventilation:
Storage and handling areas should be well-ventilated to disperse any hydrogen that may escape. Good ventilation reduces the risk of gas accumulation and potential ignition. - Avoiding Confinement:
Structures should be designed to avoid vertical confinement, allowing hydrogen to disperse quickly in case of a leak. This minimizes the risk of explosive mixtures forming in enclosed spaces.
