Throughout the entire life cycle of hydrogen, spanning from production to distribution, the imperative to minimize or eradicate leaks looms large, presenting economic burdens on top of the potential safety hazards.

Hydrogen provides a useful means to store and transport energy. Hydrogen in its pure molecular form (H2) is rare on our planet and therefore must be produced, either from water by electrolysis or from natural gas and coal. Under certain conditions which depend on the way it is produced, hydrogen can be a sustainable energy solution and can substitute or replace energy sources that have a greater impact on the environment.
Anaerobic adhesives and sealants are well placed to offer a sealing solution for hydrogen gas. They are reactive adhesives that cure rapidly to a thermoset plastic when in contact with metal surfaces in the absence of air.
