Global OTEC Announces World's Largest Onshore OTEC Demonstration Plant 

Global OTEC has announced its next major step in revolutionizing tropical energy access. The deployment of its first energy-generating onshore pilot, the OTEC Power Module®—a compact, modular power plant that turns the ocean's natural temperature gradient into continuous, clean electricity.

Unlike previous Ocean Thermal Energy Conversion (OTEC) projects that were primarily research based, this pilot will demonstrate real world scalability and readiness for mass production across more than 100 tropical and subtropical regions where the technology can thrive.

“We've moved beyond proving the concept—we're setting out the blueprints for the commercialization of a new category of renewable energy,” said Dan Grech, Founder and CEO of Global OTEC. “This demonstration plant is designed to be repeatable, compact, and efficient,
enabling a new generation of offshore infrastructure powered reliably by the ocean.”

The demonstration will be deployed onshore, drawing from existing deep seawater intake sites to tap into the temperature difference between warm surface water and cold deep ocean water.

This natural gradient will drive an Organic Rankine Cycle system with next generation components, generating up to 500 kW of clean baseload power, day and night, all year round.

Global OTEC expects to finalize a location this year. The project aims to validate the technical performance, cost efficiency, and replicability of the OTEC Power Module ahead of offshore trials.

Compact and modular by design, the OTEC Power Module is a game-changer for offshore operations. From powering remote subsea pumps and wells to providing energy for ports, data centers, and island communities, the technology offers a low-carbon alternative
for long subsea tiebacks, reducing both CAPEX by 50%.

This pilot comes just months after Global OTEC introduced the Power Module at the 1st Brazilian Workshop on Geothermal Energy Utilization and Storage, hosted by Petrobras. In parallel, the company is advancing construction of its floating, storm-resistant
prototype in Gran Canaria, Spain, showcasing both the energy system and structural innovations required to scale OTEC offshore.

“Moving beyond whitepapers and lab tests, building physical OTEC systems is essential,” Grech added. “Our vision is a future where OTEC is seen as a cornerstone of the global energy transition.”
