- Abstract
- As environmental awareness increases along with the climate crisis, efforts for more eco-friendly shipping are being emphasized. International maritime regulations have begun to regulate the emissions of ships more stringently through MARPOL, and in response, so called eco-friendly marine fuels and systems such as LNG, hydrogen fuel cells and scrubber systems have begun to be introduced.However, approaches for measuring environmental friendliness and tightening regulations of the current shipping industry, are not designed to be applicable to the upcoming eco-friendly marine systems and fuels, but also have limitations in focusing only on the fuel consumption phase. In addition, it is impossible to consistently measure the eco-friendliness of ships in all fleets from an integrated point of view.In this context, generally measuring the eco-friendliness of alternative marine fuels and systems could exacerbate such a fundamental issue for serious climate crisis and marine environmental problems.To overcome those identified limitations, parametric trend life cycle assessment (PT-LCA) was developed and applied to representative marine alternative fuels and systems which are SOx scrubber systems, LNG fuelled ships, and hydrogen fuel cells.As a result, it was found that ship age and power were closely related key parameters and the proposed LCA-based methodology can evaluate the different emission levels of fuels and systems applied to various ships by reflecting LCA perspective, as well as obtain the general trends of emission levels over ship parameters expressed as simple equations.In addition, the proposed approaches taken to develop those frameworks are strongly believed to offer a meaningful insight into future regulatory and decision-making frameworks. Thus, the novelty of this project can be placed on the provision of an insight into the optimal selection of alternative fuels and systems depending on ship characteristics.
