Blu., a Utah company specializing in Liquefied Natural Gas (LNG) refueling infrastructure will, in partnership with Intermountain Gas Company, launch a gas recapture system at the Blu. LNG fueling station in Nampa, Idaho, said to be the first of its kind in the country.
This system captures boil-off gas from the LNG storage tank and returns it to the Intermountain natural gas pipeline, which eliminates the venting of excess LNG into the atmosphere.
Blu. CEO Merritt Norton said: “By returning excess gas to the natural gas distribution system, we are increasing efficiency, saving money, and reducing greenhouse gas emissions.”
With this gas recapture system, boil-off LNG is released from the LNG tank into a pressure regulator, then warmed and returned to gas form. A chemical odorant is added for safety and consistency purposes, and then the gas is pressurized to match the pressure of the natural gas pipeline and injected into the pipeline. Prior to passing into the pipeline, the gas is metered, and the vented gas is sold to Intermountain at a commoditized rate.
The recapture system requires a minimal investment up front and is estimated to pay for itself within a year.
The gas recapture system in Nampa is the first example of a larger Blu. initiative to make LNG the preferred alternative fuel source by implementing efficient fueling solutions at all of the company’s stations by 2015. This includes plans to install gas recapture systems at other Idaho facilities, including Jerome and Idaho Falls, and eventually at all of its fueling stations that have access to a nearby natural gas pipeline and cooperation from the local gas utility.
Blu. operates 24 LNG fueling locations.
