Abstract

In this study, well to hull was obtained by life cycle assessment (LCA) and the greenhouse gases, regulated emissions, and energy use in transportation model (GREET), which is developed by Argonne National Laboratory to evaluate the environmental impact of marine liquified natural gas (LNG) and marine fuel. This study compared the environmental impact of marine LNG and marine fuels, which were caused by green house gases (GHG) emissions and energy consumption. The effect resulted from well to pump (WTP) process and pump to hull (PTH). Natural gas has the potential to generate more greenhouse gases than liquid fuels due to the amounts of leaks of the gas that were sent out the air during production and processing. Nevertheless, the results showed that the greenhouse gases produced during transportation were enough to reduce the disadvantages of PTH process. The research expects that the results will be in accordance with the environmental policy of South Korea.
