May 1, 2021 – The US Army awarded a contract to Skyhaven to develop a liquid hydrogen peroxide generator system. Industrial room-size vaporized hydrogen peroxide (VHP) sterilization devices are available for low-temperature sterilization such as commercial units provided by Steris, Bioquell, and Battelle. These systems use a disposable cartridge containing 35%-59% (wt) liquid H2O2 that is punctured when activated to release and vaporize hydrogen peroxide. However, these present VHP systems are problematic in that they require EPA regulated and controlled concentrated H2O2 canisters for each activation. This gets to be expensive and wasteful especially since H2O2 decomposes relatively fast giving the canisters a short shelf life. Furthermore, supplying these concentrated H2O2 canisters complicates logistics making the use of these large-scale VHP sterilizer units problematic for military operations. One manner to overcome these difficulties with using concentrated H2O2 canisters is to generate liquid H2O2 on-site as it gets fed to the large size vaporized hydrogen peroxide sterilizer units. A new method is being developed by Skyhaven Systems that produces a concentrated 35% liquid hydrogen peroxide sterilant using air and water. With this system, it will be easier to produce an effective sterilant in forward military operating areas.
