Hydrogen Mitigation

Removing Hydrogen in Indoor Facilities and Enclosures

Hydrogen accumulation in enclosed environments has the potential for fire and explosion. Installation of hydrogen removal devices in such environments is crucial to mitigate hydrogen risks. With decades of expertise investigating hydrogen behaviour, CNL’s comprehensive safety program offers a suite of solutions to mitigate the risks of hydrogen accumulation due to operational or accidental releases.

CNL is recognized internationally for the development of a series of innovative catalyst-based technologies that can safely remove hydrogen in enclosed environments, including actively and passively operated devices.

How Does the Hydrogen Mitigator Work?

The hydrogen mitigator is available in various configurations depending on the application need. Inside the mitigator are catalysts in various shapes, developed by CNL, that detects and reacts hydrogen with oxygen (in air).

Hydrogen in the air needs to reach a concentration of 4% by volume to become flammable. But even at a concentration less than 1%, hydrogen will automatically react with oxygen on the catalyst surface and generate water vapour. The mitigator will continue automatically drawing fresh gas mixture into the mitigator.

What Makes Hydrogen Mitigators Perfect for Your Facility?

Low investment and high benefit.

Reliable and flexible system. Cost saving measure, removes the need for additional space ventilation.

Self-starting, no power or operator action required.

Easily retrofitted into any existing facility. Easy to implement. Simple and cost-effective to maintain.

Installation

Hydrogen mitigators are simple to install in nearly any location. The compact housing is easy to transport and needs minimal maintenance. Due to its compact design, the mitigator can be installed individually or in groups, allowing for effective hydrogen removal throughout the facility.

Why CNL Hydrogen Mitigators?

Nuclear Safety Standards

CNL’s Passive Hydrogen Recombiners meet nuclear quality assurance standards and can be installed in various types of nuclear facilities.

CNL’s recombiners have been installed in nuclear reactors in Canada, France, Finland, Ukraine, and South Korea.

Self-starts, Self-stops and Self-feeds

The mitigator is designed to not rely on any power source or operator action.

CNL Coating

The proprietary CNL formulations for the mitigators are developed specifically for application in hydrogen facilities. They are not deactivated by humidity and are specially formulated to operate over a wide range of temperatures.

Customisation

CNL can develop custom mitigators for specific applications upon request.
