A Guide to Hydrogen Handling, Safety, and Storage Solutions

With an availability of 73%, Hydrogen is the most abundant natural element in the universe. Apart from that, hydrogen has now become a prominent fuel source for various mechanical and industrial settings, making it one of the top valuable natural elements for industrial sustainability. However, given the highly flammable nature and permeable tendency, it must be kept inside a specialised storage setting and storage medium. 

To keep you informed about hydrogen handling best practices, we have curated this blog post. It covers hydrogen basics, hydrogen handling practices, storage methods for different hydrogen states, and how to choose the right medium for hydrogen containment.  

A] Understanding Hydrogen

Hydrogen is a colourless, odourless, and highly flammable natural gas known for its high abundance in the universe. It is the lightest element and exists as a diatomic molecule (H2) with one proton and one electron. Due to its high energy density and zero-emission combustion, hydrogen is becoming a prominent source of fuel for various on-road and off-road settings. It is widely used as an energy means in industries, like petroleum, refining, fertilizing, transportation, and powering fuel cells. However, due to its low density, high flammability, and permeability, it requires a robust storage medium to enclose its physical properties when not in use.

B] Hydrogen Handling: Safety Guidelines and Best Practices 

1. Safe Handling of Hydrogen in Industrial Settings

To safeguard industrial settings from the risk of fire, explosion, and asphyxiation, safe handling of hydrogen in industrial settings is extremely important. Leak detection arrangements, proper ventilation, and the use of appropriate equipment and PPE suits are the best preventive measures. Industries must incorporate these suggested measures to keep the workers and physical properties safe from any potential accidents. 

2. Preventing Hydrogen Leaks and Explosions

Hydrogen is an extremely flammable gas, causing a risk of explosion and thus damaging life and property. Seeing that, it is vital to implement the correct use of safety barriers. It should involve safety barriers like robust storage medium, leak detection technologies, and proper ventilation. In addition, use storage medium manufactured from steel, aluminum, and copper alloys to prevent hydrogen embrittlement. 

3. Personal Protective Equipment (PPE) for Hydrogen Handling

Personal protective equipment is a highly recommended suit that must be worn while handling hydrogen or entering a hydrogen environment. The PPE kit includes flame-resistant clothing, chemical-resistant gloves, safety goggles, and a face shield to follow the safety protocols or protect against potential hydrogen accidents. These protective gears provide comprehensive safety cover from potential hydrogen hazards. 

4. Emergency Response for Hydrogen Accidents

Any industry dealing with hydrogen storage solutions must have an emergency response ready to counter any untoward incidents due to hydrogen’s highly flammable property. The emergency response team should be skilled in fire suppression techniques and evacuation procedures. Effective coordination with teams ensures smooth and safe responses during emergencies. 

C] Hydrogen Storage Methods: Exploring Different Approaches 

1. Compressed Hydrogen Storage

Compressed hydrogen requires extremely robust cylinders as hydrogen is stored at high-pressure (ranging from 350 to 700 bar). In such cases, high-pressure steel hydrogen gas cylinders are known as the best hydrogen storage methods for hydrogen containment. It is widely used across various industries. Also, these robust cylinders are highly cost-effective, providing an inexpensive way of storing compressed hydrogen. 

2. Liquid Hydrogen Storage

Liquid hydrogen is stored at cryogenic temperature (-253°C) to sustain its state. If any storage medium doesn’t insulate its temperature and maintain its state, it is not worth considering. A storage medium that has advanced insulation features with excellent evaporation prevention characteristics is suitable for liquid containment. It can be in spherical or cylindrical shape, based on usage and size requirements. 

3. Hydrogen Storage in Solid Materials

Hydrogen storage in solid materials is an emerging solution that enhances safety and efficiency in long-term hydrogen containment. Metal hydrides, such as magnesium and titanium-based alloys, offer a reliable method of storing hydrogen at lower pressures, reducing the risk of leaks and explosions. Carbon-based materials, including graphene and carbon nanotubes, provide lightweight and high-capacity hydrogen storage options. These advanced materials are being explored to improve hydrogen storage capabilities, making them a viable option for various industrial applications.

4. Underground and Pipeline Storage

Underground and pipeline storage methods are essential for large-scale hydrogen distribution, ensuring a stable and continuous supply. Additionally, pipeline storage facilitates the seamless transportation of hydrogen across different locations, integrating well with existing natural gas infrastructure. These storage solutions play a crucial role in supporting hydrogen-based energy systems and industrial applications.
