Overview:

Palladium and palladium alloy membranes have been known for over 100 years to selectively permeate hydrogen over all other gases. The nearly infinite selectivity of palladium alloy membranes is due to the nature of the permeability process.

Hy9 Corporation’s technology portfolio for producing and purifying hydrogen is built around a planar palladium/copper alloy membrane that extracts pure hydrogen from hydrogen containing gas mixtures much like a filter. Palladium/Copper unlike pure palladium and other alloys such as palladium/silver, is not subject to hydrogen saturation at low temperatures and the resulting damaging effect of hydrogen embrittlement. Hy9's HPS^TM purifiers do not require purging on start-up or shut down.

Hy9’s membrane technologies are readily applied broadly in “fuel flexible” systems for producing hydrogen from a large variety of hydrogen containing fuels, including the full range of hydrocarbons from natural gas to (gasified) coal.

Based on a core technology that was commercialized after a decade of development, all Hy9 products share the common elements of high productivity, low-cost membranes and leak-tight seals. Scalability is inherent by varying the number of membranes in a module or using an array of modules to meet a hydrogen output requirement.
