MARAD releases natural gas fuel cycle study
The Maritime Administration (MARAD) released a study that evaluates total fuel cycle emissions for natural gas versus conventional marine fuels.
This study was conducted as a part of MARAD’s Maritime Environmental & Technology Assistance program, which focuses efforts on emerging marine transportation and environmental issues. The study uses updated data on leakage rates in the natural gas fuel cycle to compare emissions from liquefied natural gas (LNG) or compressed natural gas (CNG) to petroleum marine fuels. Results of the study showed that the use of natural gas as a propulsion fuel can reduce air quality pollutants and reduce major greenhouse gas emissions when compared to conventional fuels.
The information provided by this study is important as marine transportation stakeholders evaluate the use of natural gas as a viable alternative propulsion fuel for reducing air polluting emissions. The research was conducted through a cooperative partnership with the Maritime Administration, the University of Delaware and The Rochester Institute of Technology.
