Honolulu Seawater Air Conditioning LLC has embarked on a $240 million project to cool half of the buildings in downtown Honolulu using super cold seawater pumped from the ocean.
By sucking up water through a pipeline running hundreds of feet below the sea, the Honolulu Seawater Air Conditioning LLC will be able to discharge the cold seawater through air conditioning units around Honolulu. The project stands to reduce the electricity used in the city's air conditioned buildings by up to 75 percent, as well as cut carbon emissions and the use of refrigerants that contribute to ozone depletion.
