Since launching Southeast LNG Distribution Company (Southeast LNG), we have received many questions
Who is Southeast LNG?
What is LNG?
LNG, or liquefied natural gas, is natural gas that has been cooled to 260 degrees Fahrenheit.When cooled to this temperature, natural gas converts from a vapor to a liquid.One (1) cubifoot of LNG is equivalent to approximately 600 cubic feet of natural gas vapor.This conversion maximizes the capacity to store and transport natural gas on transport ships, and at receiving and storage terminals.
Why is greater availability of LNG as a transportation fuel important? reduces greenhouse gas emissions and preserves domestic energy resources while still providing cost savings that can be passed on to consumers.Approximately 26.7million gallons of LNG were sold to the trucking market in 200About 3,000 heavyduty trucks, transit buses, waste collection trucks and other vehicles now use LNG as a primary fuel.While the majority of these vehicles are in California, Arizona and Texas, increasingly stringent emissions standards and rising petroleum prices
What will be the source of the LNG transported by Southeast LNG? The LNG transported by Southeast LNG willinitiallycome from Southern LNGs Elba Island terminal near Savannah.The LNG at Elba Island is imported from various production facilities around the world.Who regulates LNG truck transportation? What measures will be taken to ensure the safe ground transportation of LNG? The tanker trucks used to transport LNG have many safety components, including an outer vessel of carbon steel What could happen if an LNG tanker is involved in a traffic accident near my property? Given the safety features built into each LNG tanker, and because natural gas will not ignite in its liquid state, a fire is highly unlikely.In additionthe pressurerelief equipment and safety shutoff valves on each truck are designed to contain the LNG in the event of an accident.If LNG were to spill, it would vaporize.
LNG trucks have an excellent safety record.There has been no recorded incidenceof explosion or uncontrolled fire as a result of an LNG truck accident,and in accidents that have involved an LNG spill, the leak has been minor.
How does the transport of LNG compare to the transport of gasoline?
The tankers used in LNG transportation are different from the tankers used for gasoline transportation.An LNG tanker is insulated with fiberglass, has a carbon steel outer jacket and double walls that are vacuum insulated.Additional safety features include pressurerelief valves, gas detectors and safety shutoff valves.
What is the proposed route for Southeast LNG trucks? The proposed route is approximately 8.4 miles long and travels the following path: Elba Island Road President Street Truman ParkwayDeRenne Avenue Interstate 516 / Lynes Parkway.President Street passes through a primarily industrial section (2.2 miles) leading to the Truman Parkway interchange.There are three intersections with traffic signals on President Street through whichtrucks would pass.The Truman Parkway President Street interchange is a partial cloverleaf, where trucks entering from the east would be required to enter at minimal speeds.Truman Parkway is a limited access road approximately 4.5 miles in length from President Street to the DeRenne Avenue interchange.The DeRenne Avenue corridor is approximately 1.7 miles long and contains eight intersections with traffic signals.The corridor is mixed use with commercial/professional uses on the north side of the roadway and residential properties on the south side of the roadway for the first 1.2 miles.The remaining 0.5 miles transitions to a commercial corridor that connects toInterstate 516 / Lynes Parkway Why was the proposed route chosen?
The President Streetto Truman Parkway route is most favorable because of its shorter distance, lower accident rate and avoidance of Savannahs historic district.
Two alternative routes were considered.The first alternative route considered (Elba Island Road Islands Expressway US80 Truman Parkway DeRenne Avenue I516 / Lynes Parkway) is longer, has higher traffic volumes, more intersections (including one with a dangerous turning radius for trucks), and a higher historical collision rate.Another alternative route (Elba Island Road President Street Bay Street Lathrop Avenue Louisville Road US17I16) was considered andthen eliminated because it travels through the historic district of downtown Savannah.How many trucks are projected to travel the proposed route each day? Initiallyonly 10 trucks per day are planned to travel the proposed route.This number represents less than 0.1% of current daily vehicle traffic volumes.Additional trucks will be phased in as the market develops, but maximum capacity (58 trucks) will still represent less than 1 percent of current daily vehicle traffic.What impact will the LNG trucks have on traffic in Savannah? The impact of the LNGtrucks on Savannah traffic is expected tobe minimal.The number of trucks being added to the daily traffic patterns is nominal and the route was carefully chosen to ensure the least impact possible to the Savannah community.What impact will the use of LNG for heavy-duty trucks and buses have on the environment? According to the U.S.Department of Energy, when compared to current advanced diesel alternatives, the use of LNG can reduce toxic and carcinogenic pollutants, particulate matter by 86 to 96 percent, nonmethane hydrocarbons by 56 to 96 percent, nitrogen oxides (NOx) emissions by 17to 80 percent, and carbon dioxide (CO) emissions by up to 30 percent.Where can I find more information about Southeast LNG?
