Belgian Firm Suggests No Liner at All for Lightweight Tanks
The principals of Belgium-based Covess tested the waters of the U.S. natural gas vehicles market at ACT Expo 2104, striving to determine the best initial size for a new type of lightweight, “LongLive” brand compressed natural gas fuel cylinder – a “Type V” fuel vessel with no liner at all.
Instead of wrapping carbon and glass fibers over a plastic liner, as today’s Type IV manufacturers do, Covess places its fiber using centrifugal force, allowing the final product to be the lowest possible in weight.
The Hasselt-based firm, working with the Netherlands’ DSM, claims a “unique” polyamide (nylon) matrix material it says is up to 150 times less permeable by methane than conventional materials. Being a thermoplastic, it is fully recyclable.
Covess Is Looking for a U.S. Manufacturing Site Too
Customers can choose their own strength fibers – carbon, glass or “hybrid,” depending on application, Covess says.
Customers, Tony Vanswijgenhoven of Covess told F&F, say they want large lightweight cylinders suitable for large natural gas vehicles. Covess is seeking manufacturing locations too, eyeing sites in Ohio, Pennsylvania and Connecticut, he said.
