ICE Thermal Harvesting and UniSea Launch Alaska Seafood Industry's First Waste Heat to Power System

Modular energy technology brings clean power to Dutch Harbor - offering a scalable model for rural Alaska.

DUTCH HARBOR, Alaska, Sept. 4, 2025 /PRNewswire/ -- ICE Thermal Harvesting, LLC ("ICE") and UniSea, Inc. ("UniSea") have successfully completed the first deployment of a Waste Heat to Power (WHP) system in Alaska's seafood industry. Installed at UniSea's Dutch Harbor processing facility, the system captures waste heat from existing generators and converts it into clean, emissions-free electricity—marking a milestone for sustainable energy use in Alaska's seafood sector.

Engineered to operate in the harsh and remote conditions of the Aleutian Islands, the modular WHP system transforms excess thermal energy from UniSea's powerhouse into usable power. This reduces diesel consumption, cuts operational costs, and lowers greenhouse gas emissions all while reinforcing energy resilience in one of the most challenging working environments in North America.

"This project demonstrates how innovation and practicality can come together to create sustainable solutions even in the most challenging locations," said Rob Bordenave, Vice President at ICE, "It not only benefits UniSea by lowering fuel costs today, but also positions them for long-term resilience against volatile energy prices."

The custom-engineered system is designed to withstand the unique environmental challenges of Dutch Harbor, including high winds, seismic events and frigid temperatures. The system was integrated with UniSea's existing powerhouse, requiring no overhaul to current infrastructure and ensuring minimal disruption during installation and operation. 

During the initial three-week start-up phase of the project the ICE system generated 67MWh of electricity, representing 5000 gallons of diesel saved. As commissioning is completed and the project enters long-term operations, the system will generate 300kW and replace ~3500 gallons of diesel usage each week during the processing seasons.

Dustin Hamilton, UniSea's Chief Operating Officer, said "ICE Thermal's team members are true professionals in the waste-heat capture space. UniSea is proud to partner with them. Deploying the WHP system furthers UniSea's sustainability efforts by reducing our use of fossil fuels and is a significant step in achieving our decarbonization initiatives. This is a great moment for UniSea." 

The system's modular design makes it scalable and adaptable to facilities throughout Alaska, particularly in rural and off-grid communities where diesel remains the primary energy source. The success of this project illustrates a clear, economically viable pathway toward decarbonization and energy independence for industrial operators, utilities, and remote communities alike.
