Honolulu Seawater Air Conditioning

Honolulu Seawater Air Conditioning

More Renewable Energy

Why We Invested

To create a seawater air conditioning district cooling system to downtown Honolulu

As one of the largest energy-efficiency projects in Hawaii, Honolulu Seawater Air Conditioning promises significant energy savings that will help move us closer to our goal of more renewable energy use for the state. The system will provide an alternative to using imported fossil fuels to cool downtown Honolulu, which will decrease Oahu’s environmental footprint and the state’s oil dependency.

In June 2019, the project reached an environmental agreement with the State of Hawaii Department of Land and Natural Resources on mitigating any potential impacts on marine life, and HSWAC will use marine biologists and engineers to ensure minimal disruption. With the agreement, all major permits for the project have been secured.

Our Partner

Honolulu Seawater Air Conditioning will provide air conditioning to buildings in downtown Honolulu by pumping deep ocean water through a pipeline more than four miles offshore to a cooling station in Kakaako.
