Liquefied Natural Gas for Trucks and Buses
Liquefied natural gas (LNG) is being developed as a heavy vehicle fuel. The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance costeffective technologies for operating and refueling natural gas–fueled hea...
متن کاملExamining the Impacts of Methane Leakage on Life-Cycle Greenhouse Gas Emissions of Shale and Conventional Natural Gas
conjunction with horizontal drilling. However, the environmental implications of NG production and its use have been called into question.1-4 One of the major concerns is the amount methane (CH4) leakage from production activities and its impact on the life-cycle greenhouse gas (GHG) emissions of NG. Examining the Impacts of Methane Leakage on Life-Cycle Greenhouse Gas Emissions of Shale and Co...
متن کاملFeasibility of landfill gas as a liquefied natural gas fuel source for refuse trucks.
The purpose of this paper is to develop a methodology to evaluate the feasibility of using landfill gas (LFG) as a liquefied natural gas (LNG) fuel source for heavy-duty refuse trucks operating on landfills. Using LFG as a vehicle fuel can make the landfills more self-sustaining, reduce their dependence on fossil fuels, and reduce emissions and greenhouse gases. Acrion Technologies Inc. in asso...
متن کاملComparison of life cycle greenhouse gases from natural gas pathways for medium and heavy-duty vehicles.
The low-cost and abundant supply of shale gas in the United States has increased the interest in using natural gas for transportation. We compare the life cycle greenhouse gas (GHG) emissions from different natural gas pathways for medium and heavy-duty vehicles (MHDVs). For Class 8 tractor-trailers and refuse trucks, none of the natural gas pathways provide emissions reductions per unit of fre...
متن کاملLiquefied Natural Gas Developments Specialreport
A multi-tube, spirally-wound, cryogenic heat exchanger, the main heat exchanger (MHE) is the principal piece of heat-transfer equipment in mixed-refrigerant liquefaction cycles for producing liquefied natural gas (LNG). An MHE unit operation model called the spirally-wound tube-bundle module was developed as an integral component of the dynamic simulation capabilities for a process modeling pac...
