Chart Industries, Inc. has increased the capacity of its standard 26-inch diameter horizontal LNG onboard storage tank. The new system maximizes the volumetric efficiency of the liquefied natural gas (LNG) vehicle fuel tank by six percent or about 8 actual gallons of LNG for the 2015 model year.
Chart says the increase is significant because LNG has about 2.5 times the density of CNG. Eight additional gallons of LNG storage capacity translates into a significant improvement in tank range. Compared to CNG, Chart says an LNG tank of roughly the same physical size gets about twice the driving range of a CNG tank, with considerably less weight.
Through the use of a proprietary cryogenic super-insulation, Chart has decreased the void between the inner and outer walls of the storage tank with no loss of temperature holding capability.
"The new tank still maintains its seven-day hold time," notes Peter Murray, general manager, Chart LNG Vehicle Fueling Products.
“Continuously improving our vehicle fueling portfolio to satisfy the evolving needs of LNG end users is one of our top priorities,” said Bill Haukoos, president of Chart Distribution & Storage Americas. “The increased capacity of our new LNG tank means more time on the road and less at the pump for truck drivers, ultimately having a positive effect on their bottom line.”
