Establishment of the Ocean Thermal Energy Association

Screen Capture of OTEA’s First General Meeting (online) Jan 20, 2021

The Ocean Thermal Energy Association was established October 20, 2020 at an online meeting of elected regional delegates. The Ocean Thermal Energy Association (OTEA) is a volunteer organization providing a means for collection, coordination, and dissemination of information for Ocean Thermal Energy Conversion (OTEC) stakeholders. The Association is transnational, non-political, and dedicated to the realization and future growth of commercial OTEC deployment.

Ocean Thermal Energy Conversion (OTEC) and related technologies such as seawater air conditioning (SWAC) and Deep Ocean Water (DOW) use have long been relatively unknown despite significant research and implementation around the world. Over the past 8 years, various countries have hosted the annual International OTEC Symposia, which have brought together stakeholders to discuss ideas and developments, but many felt a more organized framework was necessary to connect stakeholders and contribute to ocean thermal energy development. 

The OTEA has more than 370 members and observers from 41 countries and regions.


OTEA Leadership and Organization

The OTEA is led by an Executive Committee comprised of delegates. Delegates are elected by their peers from each country or region with 3 or more members. There are also collective delegates representing countries and regions with fewer than 3 members. The ExCo is led by an elected Chair and two Vice-Chairs, and the day to day operations are carried out by the Secretariat, which is led by an appointed Secretary General.
