Current Projects

Ocean Thermal Energy Corporation (OTE) is moving forward with its proven technology and hands-on experience to harvest deep ocean water for a number of sustainable opportunities that will improve the lives of literally millions of people worldwide. More and more Governments and Communities recognize OTE as a leader in Ocean Thermal Energy Conversion (OTEC) and Seawater Air Conditioning (SWAC). Together, these technologies provide solutions for some of the world's greatest challenges:
  • Desalinization of the deep ocean water in commercial quantities at very competitive rates in comparison to current ocean desalination
  • Ocean Thermal Energy Conversion (OTEC) which provides base-load (24/7) power (without fossil fuels) at a cost always better than our customers' next best alternative
  • Seawater Air Conditioning (SWAC) using the deep seawater for air conditioning of large structures and buildings (hotels, medical centers, etc.) - this technology uses up to 90% less energy when compared to traditional systems
  • Sustainable food production in the form of aquaculture and agriculture projects, utilizing the nutrient rich seawater used in the above mentioned technologies
Our technologies are environmentally benign, with no negative impact on any part of the ecosystem. OTEC and SWAC production units have been proven to be virtually carbon neutral.

Common Ground

Ocean Thermal Energy Corporation (OTE) was founded upon the principle that, in seeking common ground, we not only foster a more civil and peaceful world, but ultimately accomplish more in our abilities to address mounting global concerns. The vast majority of people on this planet have the same needs and desires for themselves and their families: food, clean water, electricity and security. Learn more »
