On May 31 this year Optimum Composite Technologies, LLC., based in the US state of Utah, was awarded its patent for their Type 4 Boss from the United States Patent and Trademark Office. The company is working on certifying a type 4 CNG tank using this technology and plans on having one ready for market by the start of 2017.
Optimum has being using this technology for several years on products ranging from their small cylinders used for R&D Testing to high pressure Hydrogen tanks. The polar boss can withstand pressures beyond 25,000psi.
“Having a reliable leak free polar boss is one of the major obstacles in designing a successful type 4 cylinder. We feel extremely confident in and have proven its reliability over and over again,” commented Chief Technical Officer Mike Olson.
