The U.S. Department of Energy (DOE) formally announced two grants for hydrogen storage technology development; WireTough Cylinders LLC of Bristol,
The Energy Department was seeking cutting edge technologies to provide better storage for future uses of hydrogen as a fuel. WireTough’s goal is to develop a 30 foot tank with a large storage volume of 700 gallons (2,600 liters) at high pressures (12,700 psi). The project result will be a cost-effective solution to store hydrogen, allowing the hydrogen vehicle fuel to ultimately be sold at a target cost of $4 per gasoline gallon equivalents (GGE, 1 GGE=2.6 Kg of CNG or 1 Kg of Hydrogen).
Additionally, WireTough will be introducing their latest technology advancement: a line of ground storage solutions for compressed natural gas (CNG) filling stations with a capacity of 100 to 300 gasoline gallon equivalents (GGE). CNG fill stations of this size allow owners of fleet vehicles (delivery trucks, buses, garbage trucks, etc.) to quickly refuel when they return to their terminal nightly. These ground storage units will use the company’s patent pending wire reinforcement technology to create storage tanks approved by the American Society of Mechanical Engineers (ASME) that will store CNG at 5000 psi. WireTough’s ground storage solutions are expected to cost 30% to 50% less than currently available storage tanks and the technology used will provide extremely strong tanks, using far less steel.
Currently, WireTough Cylinders makes a line of CNG vehicle tanks that are stronger and lighter in weight than solid steel (Type I) tanks and priced competitively. WireTough currently produces tanks that range in size from 57 liter water volume(5 gge) to 260 liter (22 gge). WireTough’s tank technology combines the high strength and ductility of the ultra-tensile wire in combination with a ductile steel liner produce a safe, damage tolerant vessel at a competitive price.
About WireTough Cylinders LLC
WireTough began as Polywire Tough Composites, Ltd., established in 2003, from a team of four engineers, who as a group were responsible for over 40 US patents. In 2010, WireTough Cylinders was officially incorporated. Their extensive knowledge in pressure vessels, high strength steel, machine design, composites, engineering mechanics and physics, has made their products superior in both cost and function. WireTough is known for its light weight, economical, wire reinforced pressure vessels for gas storage. In 2011 the company successfully received US DOT FMVSS-304 and ANSI-NGV-2-2007 for its Type II CNG cylinders. The company is the only producer of steel body CNG cylinders in the USA.
