Capstone Design Project Seminar: Feasibility of LNG as a transition fuel to 100% renewable energy for Hawaii

The State of Hawaii has passed legislation requiring the use of 100% renewable energy by 2045. Yet Hawaii generates most of its electricity from fuel oil and coal and less than a third through renewable energy sources. Whether or not the 100% renewables mandate is achievable by 2045, there exists an opportunity for a transitional fuel source for the island of Oahu that is both cleaner than the current fossil fuel mix and economically attractive: liquified natural gas (LNG). Converting Oahu’s electrical power plant fuel supply to LNG requires an import terminal and previous studies have identified a Floating Storage and Regassing Unit (FSRU) moored offshore of Campbell Industrial Park as an option.
We present a level-2 front-end engineering design of an offshore LNG terminal including technical, economic and regulatory feasibility. Analyses of ocean conditions and bathymetry serve to determine the mooring system location and type, as well as subsea pipeline routing and protection up to and including the landing. Operational downtime is estimated based on weather and system reliability. Environmental impact, permitting and construction are assessed and a cost/benefit analysis is performed.
***Participants are encouraged to arrive ten minutes early for a virtual coffee hour hosted by Dr. Deniz Gedikli.***
