Lincoln Composites has started to design, develop and certify what it says will become world’s largest composite high pressure tanks.
The tanks are planned to be used in the capture, transportation and distribution of compressed natural gas to remote customers. Lincoln Composites recognizes the advantages of large, lightweight, high pressure tanks due to the increased demand of compressed natural gas. The tank can be designed to a service pressure of 250 to 350 bar.
The new tank is approximately 1.08 metres diameter by 11.5 metres length with a storage volume of approximately 8700 litres (water volume). The tank will be manufactured with a low permeation, corrosion resistant thermoplastic high density polyethylene (HDPE) liner overwrapped with a toughened carbon-epoxy composite shell. The design approach and method of manufacture yield a tank that will result in a weight that is 60% less than a comparable metal tank.
It is anticipated that each tank will use one-half to one metric tonne of carbon fibre depending on the pressure rating of the tank. As a result of the expected increase in demand for carbon fibre, Lincoln Composites has entered into active discussions with carbon fibre suppliers to secure the necessary carbon fibre allocations to support the project. The annual carbon fibre requirements will approach 300 metric tones. By initiating this investment, Lincoln Composites is positioning itself to offer high pressure tanks for Hydrogen storage and delivery.
“This investment represents the culmination of 15 years work on large, high pressure, thermoplastic lined, composite overwrapped tanks,” said William Dick, President of Lincoln Composites. “We are leveraging our heritage in large aerospace/military structures at a time when the world is in desperate need of advanced technologies for its energy supply problems. We have proven ourselves in the compressed natural gas vehicle market, bulk gas transportation, hydrogen fuel storage technologies, and now, large bulk hauling tanks. Lincoln Composites is already fabricating and delivering the world’s largest overwrapped composite tank and this effort represents the next generation of extremely large tanks. We will have a product in early 2007 that we are highly confident will position us as the only manufacturer of a tank with its attractive cost to volume and weight ratios,” said William Dick, President of Lincoln Composites.”
