Abstract This report provides a summary of an investigation by the University of Hawaii Sea Grant College Program into the viability and effectiveness of installing a seawater air conditioning district cooling system in Waikiki. Seawater air conditioning (SWAC) harnesses the cooling properties of cold seawater to provide cool air for air conditioning purposes. In doing so, SWAC reduces the amount of electricity needed for air conditioning. SWAC is particularly relevant to Hawaii for two reasons: first, the proximity of deep, cold, ocean water to areas of high population make Hawaii an obvious location for implementing the technology; and secondly, with approximately 90% of its electricity generated from fossil fuels, Hawaii is the most fossil fuel dependent state in the nation. Unlike the rest of the U.S., where coal, natural gas, and nuclear power are called upon to meet a substantial proportion of the electricity demand, Hawaii relies heavily on residual fuel oil (the by-product of refining crude oil for jet fuel, gasoline, and other distillates). As a result, Hawaii has very high electricity prices compared to the rest of the country. SWAC has the potential to both cut the cost of air conditioning and reduce the amount of harmful emissions that are released as a by-product of generating electricity from fossil fuels.
