Ecolectro achieves production and efficiency milestones in AEM electrolyzers Ecolectro has achieved performance milestones using their AEM chemistry in membrane-based electrolyzers . The New York-based green hydrogen startup has achieved peak production rates of > 4A / cm ² at current densities of < 2.1V and has achieved cell efficiencies of > 74 % with high hydrogen production rates .
According to the company , its current density sets a benchmark within the AEM industry and matches the best cell efficiencies of most PEM electrolysis technologies . With this technical breakthrough , Ecolectropowered electrolyzers can provide green hydrogen at significantly lower costs . Ultimately , the company anticipates achieving further improvements with a target efficiency of an industryleading 80 % or more .
The production rate and efficiency achievements have been demonstrated using Ecolectro ’ s proprietary hydrocarbonbased chemistry , which avoids the use of any perfluoro-alkyl substances ( PFAs ), iridium-based catalysts and titaniumbased components in the plates and porous transport layers . These material innovations not only lead to an impressive 80 % cost reduction compared to PEM-based stacks , but they also significantly lower Ecolectro ’ s carbon footprint and enhance the sustainability of operations , reflecting their commitment to environmentally responsible practices .
In addition to the performance milestones , the company has successfully scaled their electrolyzers from the labscale to the pilot-scale . They have deployed a pilot electrolyzer at a utility company and have made green hydrogen on-site for further use .
Triton Hydrogen unveils Tritonex hydrogen barrier coating system Triton Hydrogen has unveiled the Tritonex Hydrogen Barrier Coating System ( HBCS ), a waterbased coating used primarily as an internal lining in pipes , storage vessels and components for protection against hydrogen leakage , material embrittlement and all forms of corrosion .
Tritonex HBCS can be applied manually and robotically , offering significant advantages for original equipment manufacturers ( OEM ) and field retrofitting . Tritonex has demonstrated zero hydrogen permeation in rigorous tests , earning it the ISO 17081:2014 certification .
Given its tiny molecular size , hydrogen can leak through even solid steel . While current containment methods can slow leakage , they cannot completely stop it , according to the company . Tritonex HBCS stands out for its unique composition and properties , incorporating a revolutionary nanoingredient that renders it completely impermeable to hydrogen . This electrically inert and chemically resistant coating also entirely prevents corrosion .
The coating ’ s resilience to extreme temperatures , flexibility in response to thermal expansion , and non-toxic nature make it ideally suited to hydrogen containment across a broad spectrum of applications .
