Low-Cost Conformable Storage to Maximize Vehicle Range

Research output: NRELSubcontract Report


Although liquefied petroleum gas and compressed natural gas are attractive contenders for converting vehicles from gasoline and diesel to alternative fuels, two factors inhibit conversion: additional vehicle costs and reduced range compared to gasoline. In overcoming these barriers, a key element of the alternative fuel system becomes the storage tank for these pressurized fuels. ThiokolCorporation has developed and is now producing a conformable aluminum storage system for liquefied petroleum gas, which increases the fuel storage in a given rectangular envelope. This project's goal was to develop the technology for a similar conformable tank made of injection-molded plastic to decrease costs.
