District Cooling From the Pacific: A Targeted Efficiency for Oʻahu

Oʻahu is on an ambitious journey towards a fully electrified energy future. As part of this significant transition, which has been meticulously charted through earlier Sankey analysis, the island is exploring innovative solutions to enhance its energy efficiency. One such groundbreaking concept is Seawater Air Conditioning (SWAC), promising a targeted approach to cooling that taps directly into the vast resources of the Pacific.

The evaluation of seawater air conditioning on Oʻahu is strategically integrated into the island’s already developed, fully electrified energy system. This framework carefully defines the scope: it focuses exclusively on the island’s civilian energy system. This means the discussion and planning for SWAC deliberately exclude sectors such as overseas aviation fuel, maritime bunkering for ships crossing the Pacific, and military energy consumption.

By narrowing the focus to civilian needs and integrating SWAC within an electrified framework, Oʻahu aims to achieve significant, targeted efficiencies. Seawater air conditioning offers a way to drastically reduce the electrical load typically associated with conventional air conditioning, leveraging the ocean’s naturally cool deep waters. This not only aligns with the island’s electrification goals but also presents a sustainable, environmentally friendly alternative to meet the growing demand for cooling.

As Oʻahu continues to build out its resilient and sustainable energy infrastructure, solutions like district cooling from the Pacific represent a forward-thinking step, ensuring a cooler, greener future for the island’s residents and businesses.
