Safety

AT ONEH2, SAFETY IS AT THE CENTER OF OUR COMMITMENT TO PROVIDE ZERO-EMISSIONS HYDROGEN FUEL SOLUTIONS.

Creating Safe Fueling Solutions

From generation to consumption, we incorporate industry safety standards into every step of our hydrogen fueling systems. The health and safety of our team, our clients, the community, our stakeholders and the environment are of utmost importance to us. We know that making hydrogen fuel a viable clean energy solution means ensuring safe generation, transportation, and utilization processes.

With any fuel source, proper safety protocols must be followed. When safe handling procedures are adhered to, hydrogen is less dangerous than gasoline and other conventional fuels. Hydrogen’s safety advantages include:

NON-TOXIC

Unlike gasoline and other fossil fuels, hydrogen is non-toxic and will not contaminate the environment or harm human health in the event of a leak.

LIGHTER THAN AIR

Hydrogen is lighter than air, which allows it to disperse quickly in the event of a leak, reducing the risk of fire or explosion.

LOWER RADIANT HEAT

Hydrogen has a lower radiant heat than gasoline, which means the air around a hydrogen flame is less hot than around a gasoline flame. This means hydrogen has less risk of secondary fires.

HIGHER OXYGEN REQUIREMENT

Hydrogen requires a higher oxygen content to ignite, making it safer in environments with oxygen.

ROBUST STANDARDS​

Multiple organizations have come together to develop robust safety standards for hydrogen systems and fuel cells. These organizations include; the US Department of Energy, International Code Council, and the National Fire Protection Association.

Safety standards for hydrogen encompass all aspects of the hydrogen fuel lifecycle – from generation to utilization. These include:

PROPER STORAGE

Hydrogen must be stored in containers specifically designed for this gas and kept in well-ventilated areas away from heat, sparks, and flames.

SAFE TRANSPORT

Hydrogen must only be transported in tanks and vehicles equipped with safety features such as pressure relief valves and explosion-proof construction.

LEAK DETECTION

Hydrogen fuel systems must be equipped with leak detection devices to quickly detect and respond to any leaks.

PROPER PROCEDURES

Fueling hydrogen vehicles should only be done in well-ventilated areas, following the manufacturer's recommended procedures.

TRAINING AND EDUCATION

Individuals who work with hydrogen fuel must receive proper training and education on its safe handling and use, including emergency response procedures.

REGULAR MAINTENANCE

Hydrogen fuel systems must be regularly maintained to ensure they're functioning properly and to identify any potential safety hazards.

SAFETY IS OUR PRIORITY​

OneH2 closely follows all hydrogen fuel safety standards. When compared to conventional fuels such as gasoline, hydrogen is a safer and more sustainable alternative. With the proper safety procedures in place, hydrogen fuel is a safe and reliable fuel source.

 

Interlock Safety​

At OneH2, user safety is just as important as the safety of the hydrogen. Through interlock safety relays, we ensure safety throughout our equipment. We have individual safety relays per H2 production module (referred to as local safety relays) plus an additional master safety interlock relay for the H400 system as a whole (referred to as a global safety relay.) Each of these layers operate independently of one another and can terminate power to the equipment when triggered. Through meticulously engineered interlock safety relays, our equipment is equipped to maintain safety at every level of operation, ensuring peace of mind for all stakeholders involved.

ECU CONTROLLED

  • Unlimited cause/effect logic conditions to trigger shutdown, and respond to shutdowns
  • Programmatic conditions by dual processor control box with backup batteries
  • RS485-ModBus communications for fault status / intermodule command and control

LOCAL SAFETY INTERLOCKS

  • Safety devices maintain a direct connection to an in-module (local) safety relay
  • Ability to shut down production module independent of state of Safety Interlock 1
  • Localized E-Stop for operator intervention

GLOBAL SAFETY INTERLOCKS

  • Master and remote E-Stop for Operator intervention, direct connection to Master Electrical 480 VAC panel
  • Direct interlocking of all production modules
  • Real time system Global Safety OK (GSR OK) communication status to all Control Systems
