Annual Report 2018

Task 11 - Ocean thermal Energy Conversion

The overall work is carried out by two groups addressing the following topics:

  1. Estimation of OTEC potential around the globe (lead by China);
  2. Present status and plans of OTEC projects (lead by Korea).

A state-of-the-art report of OTEC activities and projects around the globe has been prepared as a first step to further define a full work programme under this task. The identification of plans and new developments on OTEC in the various regions of the world would be important for OTEC power plants the development of a future roadmap which is one of the goals of this Task.


A second webinar was held on 9 November 2018, organised by the Indian Delegate, Dr Purnima Jalihal, with other 7 participants from France, Japan, Republic of Korea, and two invitees from UK and from a private company in France. In this webinar, participants discussed on how to take the task forward and issues that should be addressed by the group.

There was a consensus on the importance of promoting and disseminating knowledge on OTEC to the general public. There are a few recent progresses: KRISO in the Republic of Korea has been working on the development of a 1 MW OTEC plant and Saga University is working with Malaysia on building a new OTEC plant. The outcomes of these projects can generate outputs that are important to be disseminated to the public. A white paper on the advantages of OTEC is planned to be prepared in 2019.
