Energy demand is increasing as the world population continues to rise. As a result, a surge in greenhouse gas (GHG) emissions is expected. To mitigate this rise in GHG emissions, the sources of energy need to be clean and sustainable. A large portion of GHG emissions comes from transportation, so implementing alternative transportation fuels is mandatory. In this study, natural gas (NG) and hydrogen systems are considered sources of transportation fuels capable of meeting rising energy demand while contributing to net zero targets. To assess the environmental impacts of these considerations, an appropriate life cycle assessment (LCA) is needed. Research on state-of-the art literature was conducted to first gain information on general LCAs. Moreover, information on upstream NG systems and hydrogen, as an energy carrier, permitted to assess the characteristics of the explored LCAs. Various LCA methods and supporting models were compared to determine which was most appropriate for such systems. Due to uncertainties and limits with most LCAs, coupling a LCA with a complementary model compensates this issue. A consequential life cycle assessment (CLCA) paired with technology choice models (TCM) would assess environmental and economic consequences at a high level of detail while taking into account CLCA’s uncertainties. The findings of this study permit to fill the gaps in the understanding of implementing new alternative transportation fuels. It also sparks interest in future research on the bridge between NG and hydrogen systems.

Role: I completed all of the research alongside my research partner. Everything we did was based on researching literature that already existed and from what our mentor taught us about life cycle assessments. No physical labs were conducted.
