SIDS DOCK and Naval Energies to develop OTEC for Small Island Developing States

A UN-recognized initiative Small Island Developing States (SIDS DOCK) and Naval Energies have signed a Memorandum of Understanding to support the development of marine renewable energy.

Under the agreement SIDS and Naval Energies will collaborate to foster the development of Ocean Thermal Energy Conversion (OTEC), deep-sea conversion and floating offshore wind projects in small islands countries.

The signing ceremony took place during fifth session of the Assembly of SIDS DOCK, held on 28 September 2019,… Continue reading

Report on the 7th International OTEC Symposium

10th Okinawa Hawaii Ocean Energy and Economic Development Symposium and Workshop

Since 2010, Ocean Energy Workshops have been held alternately in Kona and Kumejima under the Okinawa Hawaii Clean Energy Partnership. This partnership was formed by a Memorandum of Cooperation signed by the Japanese Ministry of Economy Trade and Industry, the United States Department of Energy, Okinawa Prefecture, and the State of Hawai’i, to develop and deploy clean and renewable energies.

India’s policy developments are opening doors for OTEC

The ministry of new and renewable energy (MNRE) in India has declared that ocean energy is officially a renewable energy source and now falls under Renewable Purchase Obligations (RPO). This recent Policy change offers new opportunities for OTEC in India.

The RPO states power suppliers are required to procure a part of their power from renewable sources. By including Ocean Power as a renewable source, investing in OTEC is made more attractive. This… Continue reading

Ocean thermal energy ‘ideal’ to power Maldives

Ocean thermal energy conversion (OTEC) is the ideal renewable energy solution for the Maldives, according to Global OTEC Resources, an advocate for commercial OTEC systems to provide electricity and desalination to small island states. Global OTEC Resources has co-produced a paper with University of Exeter that assesses the feasibility of OTEC in the Maldives.

The paper titled ‘Assessment of extreme and metocean conditions in the Maldives for OTEC applications’ is to be… Continue reading

Flow visualization of downward condensing ammonia in a gasketed plate heat exchanger 

Recently, Maaike Leichsenring graduated from the TU Delft in Engineering Thermodynamics on flow visualization of the ammonia condensing process in a plate type heat exchanger. Generally, two-phase flow in plate heat exchangers is yet not fully understood which leads to inaccurate performance calculations. The uniqueness of the experiment is described by the fact that condensing flow of pure ammonia in a corrugated plate heat exchanger was successfully captured for the first time. These results… Continue reading

Potential effects of deep seawater discharge by an OTEC plant on the marine microorganisms in oligotrophic waters

In relation to the for 2020 scheduled 10 MW OTEC plant offshore the Martinique Island, this project called ‘IMPALA’ (Impacts of artificial upwelling on microplankton) aims to study the potential environmental impacts of releasing, below the surface, deep seawater flowing out of OTEC plant. This OTEC plant will pump approximately 100,000 m3.h−1 of deep seawater at 1100 m depth. In order to optimize the energy efficiency, the deep seawater should be rejected close… Continue reading
