Ocean Thermal Energy (OTE) Corporation is a leader in designing and developing secure ocean-based power plants. Using Ocean Thermal Energy Conversion (OTEC) and Seawater Air Conditioning (SWAC), we deliver proven solutions for 24/7 baseload electricity, high-efficiency cooling, and essential resources such as potable water, sustainable food production, and economic development opportunities. Our mission is twofold: to strengthen U.S. military energy security and to provide affordable, renewable energy to island and coastal communities in tropical regions.

We are the only OTEC company worldwide whose engineers have designed and built an OTEC system that operated successfully for many years at the Natural Energy Laboratory Hawaii Authority (NELHA). Our team has also designed OTEC systems for the U.S. Office of Naval Research and is currently designing a system for the U.S. Army—clear validation of our unmatched expertise and credibility in this field.

By harnessing the sun’s surface heat and the cold depths of the ocean, OTEC generates continuous, low-cost, clean energy and fresh water for military bases, islands, and coastal communities in tropical regions. These solutions reduce reliance on imported fuels, strengthen resilience, and deliver long-term stability for defense and civilian users alike.

With decades of research and field validation, OTE’s technologies are proven and robust, developed by dedicated scientists and engineers. Our pipeline includes Department of Defense initiatives and strong interest from islands and coastal communities.  We advance U.S. military readiness while promoting economic growth and regional stability.

Founded in 1988, OTE is led by a multidisciplinary team of executives, scientists, and ocean engineers, supported by strategic alliances with defense contractors, corporations, and financial institutions. Headquartered in Philadelphia, Pennsylvania, USA, we are positioned to bring our energy solutions to scale worldwide.
