Scientists from Pacific Northwest National Laboratory are in Guam discussing ocean thermal energy conversion (OTEC), a renewable technology that uses ocean temperature differences to generate power. Highlighted at the POWER Symposium, OTEC is well-suited for Guam’s tropical waters and could also support seawater air conditioning. While still costly and experimental, experts say it offers stable, around-the-clock energy and could significantly reduce the island’s cooling-related power demand.

The island military base of Diego Garcia has been crucial to U.S. security for decades. But now, officials fear it could come under threat from China if the U.K. gives it up. WSJ’s Shelby Holliday reports.

Investors are seeking opportunities that combine financial returns with national security benefits, particularly in the transition to secure energy solutions. Ocean Thermal Energy Conversion (OTEC) presents a unique investment opportunity, delivering reliable, fuel-free power to U.S. military bases in tropical regions.

Puerto Rico, home to 3.4 million people with nearly half living in poverty, faces persistent challenges like high energy costs and fragile infrastructure. Ocean Thermal Energy Conversion (OTEC) offers a promising solution, harnessing the ocean’s temperature differences to produce renewable energy and potable water. This technology aligns with Puerto Rico’s goal of 100% renewable energy by 2050, as outlined in the Puerto Rico Energy Public Policy Act. With OTE Corp’s expertise and successful pilot projects, OTEC could drive economic growth, create jobs, and bolster the island’s resilience against future natural disasters.

Located in the remote Republic of the Marshall Islands, U.S. Army Garrison – Kwajalein Atoll plays a vital role in global defense, supporting space operations and multiple combatant commands. As rising sea levels threaten its existence, the garrison is committed to achieving 100% carbon-free electricity by 2030, aligning with the Army Climate Strategy. After studying six energy alternatives, three were chosen for further development: solar photovoltaic systems with battery storage, hydrogen fuel cells powered by solar, and ocean thermal energy conversion. These technologies leverage Kwajalein’s unique equatorial location and deepwater access, providing a sustainable blueprint for resilient, off-grid military installations.

Bitcoin could help unlock 2 to 4 terawatts of continuous clean energy by leveraging Ocean Thermal Energy Conversion (OTEC), a 150-year-old concept that turns the Earth’s oceans into a vast solar battery. OTEC works by using the temperature difference between warm surface water and cold deep seawater to drive a heat engine, generating consistent, renewable electricity. Bitcoin’s ability to monetize stranded energy makes it an ideal partner for scaling OTEC, while the technology’s access to limitless cold water offers an exceptionally efficient and ecological solution for mining. With over a billion people living near tropical coasts, this synergy could provide sustainable power and cooling infrastructure on a planetary scale.

An alternative cooling method for Bitcoin mining centers, large buildings, airports, hotels, hospitals etc that is not frequently considered, is seawater air-conditioning (SWAC)—a renewable alternative for cooling that involves pumping seawater from ocean depths of around 700 to 1200 meters and temperatures of 3°C to 5°C to the coast, where it exchanges heat with a district cooling system. SWAC uses up to 90% less electricity when compared to conventional air conditioning systems.
