GE, Nat G Launch Natural Gas Fueling Systems
Nat G CNG Solutions has introduced its Nat G 500 Series fueling station for mid-sized fleets, priced starting at $59,900 after a federal tax credit, the company says.
The Nat G 500 Series delivers up to 23 gasoline gallon equivalents (gge) of CNG per hour when configured as a time fill unit and is also available in fast fill to provide up to 80 gge of instant fill capacity. The entire system comes pre-assembled and can be skid-mounted to allow for easy transportation and simple installation, Nat G CNG Solutions says.
The Nat G 500 Series is built around a compressor provided by Sauer Compressors USA. Sauer’s compressors are widely used aboard US Navy ships, the company says.
The Nat G 500 Series is available on a zero-dollar, five-year lease starting at 25 cents per gallon or $1,200 per month for a time fill unit, the company says.
In other natural gas fueling station news, GE Oil and Gas has introduced its LNG In A Box system, a small-scale, plug-and-play, re-deployable liquefied natural gas fueling system.
GE says the world’s first commercial application of the LNG In A Box system will be for LNG fueling stations in Europe to be delivered by Luxembourg-based LNG firm Gasfin through its operating company AIR-LNG. Gasfin has signed a memorandum of understanding with GE to install five LNG In A Box units serving “clusters” of LNG fueling stations. The first unit will be installed near the border of Italy and Slovenia, with the potential for an additional 25 units for expansion into Europe and the CIS countries.
In comparison to GE’s Micro LNG plant announced last year, this new system offers customers a more standardized, modular fueling solution covering an LNG production range of 10,000-50,000 gallons a day (16-18 tons/day). It is the first available in a 10,000-gallons-a-day capacity that reduces demand-side adoption risk and requires a low CapEx and OpEx commitment, GE says.
Small-scale solutions such as the LNG In A Box system may encourage the transition of long-haul trucks from diesel fuel to LNG. In the case of North America, fuel savings may yield a three-year payback based on current fuel prices, according to GE. This can be a major contributor to North American emissions reduction goals by potentially displacing about 1.7 million barrels a day of oil, while reducing total “well to wheels” GHG emissions by 7-15 percent, the company says.
The small-scale solution also is economically suited for customers seeking a 10-50,000-gallons-a-day production capacity. Typical LNG tanks for heavy-duty vehicles hold an average of 70-150 gallons (110-240 kg), so one 10,000-gallon-a-day (17 tons/day) system would be able to fuel up to 100 trucks per day.
Each LNG In A Box unit is fully equipped with a gas pre-treatment system, cold box assembly and boil off gas compressor as well as a GE’s turboexpander compressor, high-speed reciprocating compressor, electric motor, driver and control system. LNG In A Box units for Gasfin will be manufactured in the United States and will be shipped to Gasfin’s LNG fueling sites in Europe.
GE says the new system is suitable for numerous industry sectors including highway transportation, marine, rail and remote industries such as mining and distributed power generation.
