Lincoln Composites, Inc., a subsidiary of Hexagon Composites has been selected by Gas Technology Institute (GTI) to provide high pressure storage tanks for two hydrogen fuelling applications.
The 7000 psi (483 bar) all-composite, Type IV Tuffshell L fuel tanks will be produced in the Lincoln manufacturing facility for delivery in May 2005.
Gas Technology Institute is working on a project in conjunction with the U.S. Department of Energy (DOE) to produce two hydrogen fuelling stations: a stationary 50 kg/day, high pressure hydrogen fuelling station using reformed natural gas, and a trailer-mounted portable fuelling station for short-term hydrogen vehicle demonstration activities. An important component of a gaseous fuelling station design is the high pressure gas storage system.
A fuelling station used to fill hydrogen vehicles to 5000 psi (350 bar) requires a storage system operating at higher pressures. Lincoln Composites believe that their Tuffshell tanks are an ideal fit for this application, as they are capable of high operating pressures while providing the cycle life necessary for a fuelling station.
According to William Dick, President of Lincoln Composites, ""A 5000 psi Tuffshell tank was recently subjected to over 500,000 cycles at 125 percent of service pressure. This type of testing demonstrates the benefits of our Tuffshell technology as it relates to cycle life, durability and performance.""
""Lincoln Composites' high-pressure hydrogen containers look attractive for hydrogen storage,"" says Bill Liss, Director of Hydrogen Energy Systems at GTI. ""For stationary uses, the largest pressure vessels are price competitive with steel and lower than alternative composite storage vessels. For the portable hydrogen station, the combination of price and lightweight make the Lincoln containers attractive.""
Lincoln composites claim that their Tuffshell tanks provide high cycle performance while maintaining their lightweight properties and low cost, something they suggest to be a critical aspect when considering the transportation of hydrogen gas. ""When the goal is to transport hydrogen fuel as opposed to heavy metal tanks, our Tuffshell tanks are the optimal and most cost-effective solution. Our tanks are more competitive than metal lined tanks in weight, cost, and cycle life; hydrogen fuelling stations are an ideal use for our technology,"" stated William Dick.
As the rail sector looks to new technologies to enable it to answer sustainability, performance and cost challenges, applications for pultruded composites are set to grow, according to a new report from the European Pultrusion Technology Association (EPTA). Lightweight, high performance, durable composites offer energy efficient solutions with lower environmental impact and reduced through-life costs in rolling stock and rail infrastructure.
