Ocean Thermal Energy Corporation designs and develops ocean-based energy systems that combine ocean thermal energy conversion with seawater air conditioning to deliver continuous baseload power, efficient cooling, and essential resources such as potable water and support for sustainable food production in tropical island and coastal regions. These solutions primarily serve military bases and coastal communities, aiming to reduce reliance on imported fuels and enhance resilience. The company can point to a track record including a long-running OTEC operation at Hawaii's Natural Energy Laboratory and collaborations with the U.S. Office of Naval Research, with current work for the U.S. Army underscoring its engineering credibility. Headquartered in Philadelphia, Pennsylvania, and founded in 1988, OTE describes itself as a small to mid-sized organization supported by strategic alliances with defense contractors, corporations, and financial institutions. In October 2025 it announced a new engagement with the U.S. Army to design a 17.2-megawatt OTEC and desalination system for Kwajalein Atoll.
