Safe and efficent bonding solutions for hydrogen sealing, storage, and transportation.

Hydrogen production and an effective hydrogen supply chain is becoming a crucial element in transitioning to sustainable energy. Generated by renewable energy, hydrogen is a zero-carbon alternative to methane, making it key for the reduction of greenhouse gas emissions. To be able to adopt hydrogen as a green energy source it needs to be produced at scale – meaning infrastructure needs to be adapted. Improper sealing materials can lead to leaks and catastrophic failure, so it is vital that all hydrogen sealing materials be approved for use and compliant - such as KIWA Inorm KE214 and GASTEC QA AR 214.

TECHSiL offer an innovative range of hydrogen sealing solutions which are certified for hydrogen applications, such as fuel cells, valves and pipes throughout production and storage, and electronic components that encounter Hydrogen gas/liquid. Our high-performance hydrogen sealing materials include threaded sealants, O-Rings, engineering adhesives, and more.

Hydrogen Sealing Challenges: TECHSiL's guide to hydrogen bonding

• Hydrogen will permeate most materials due to its low molecular size and high diffusity - leak-proof sealing is crucial
• Requires low temperatures and cryogenic conditions when stored as a liquid or gas 
• When compressed, volumetric energy density increases requiring storage components to withstand very high pressures
• Seals within electrolysis equipment require high chemical resistance and must be able to withstand aggressive environments - they need to work between -40C and 150C
• Efficient leak prevention sealing is vital for passanger safety, when used as fuel in vehicles
