The OTEC Symposium brings together industry experts, researchers, students, government representatives, and NGOs from around the globe to foster networking and collaboration. The primary objective is to disseminate recent scientific findings and technological innovations concerning the various processes and applications based on deep ocean water, including OTEC, SWAC, DOWA, and associated technologies.

Therefore, the 12th International OTEC Symposium will be held entirely in Bora Bora from December 1st to 4th, 2026, with the official Opening Ceremony taking place on December 2nd. It will also be available online.

Bora Bora is a volcanic island of French Polynesia located in the southern Pacific, about 260 km northwest of Tahiti (50 minutes with local airline). As all international flights to French Polynesia land in Tahiti, we highly recommend planning your arrival in Tahiti on November 30th, 2026, to ensure a seamless domestic transit to Bora Bora before the event begins.

Bora Bora is not only a world-famous destination but a pioneer in environmental preservation and deep sea water utilization. Recognized for 25 consecutive years with the prestigious "Pavillon Bleu of Europe" label, the island serves as a living laboratory for the blue economy. From pioneering large-scale Deep Ocean Water Sea Water Air Conditioning (SWAC) systems to implementing eco-friendly municipal infrastructures, the Municipality of Bora Bora is deeply committed to sustainable innovation, making it the perfect setting for this year's symposium.
