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

Allseas targets renewables with acquisition of OTEC specialist Bluerise

Allseas has acquired Bluerise, a specialist developer of Ocean Thermal Energy Conversion (OTEC) technology that delivers renewable energy solutions.

Based in Delft, the Netherlands, Bluerise has been researching and developing OTEC technology for 9 years, designing systems that utilise the natural temperature difference in the ocean between cold deep water (5°C) and warm surface water (25°C) to generate clean electricity.

Allseas will use its offshore expertise and record of deep-water technologies to advance Bluerise concepts… Continue reading

7th International OTEC Symposium

7thOTECSymposiumOn September 26-28, the 7th International OTEC Symposium will be held in Busan, Republic of Korea. Busan is a beautiful maritime city, and is the second largest metropolitan city in Korea. Bridging between Asian continent and Pacific Ocean, it has been a hub port for fisheries and other maritime industries in North East Asia.

The symposium is hosted by Korea Research Institute of Ships and Ocean Engineering (KRISO) and Korea Society for Power System Engineering… Continue reading

Ocean thermal energy holds promise for Oman

Oman has the potential to harness the ocean’s inexhaustible thermal energy for power generation and district cooling, among other commercial applications, according to an international expert specialising in the use of this renewable resource.

Berend Jan Kleute (pictured), Co-Founder of Bluerise — a Dutch-based company known for its pioneering Ocean Thermal Energy Conversion (OTEC) technology — said the capital region, Muscat, among other coastal towns and shore-based installations, are located in the relative proximity of… Continue reading

Japan Supported Project toward Development of Advanced Hybrid OTEC in Malaysia

The Japan Science and Technology Agency last month announced seven new SATREPS (Science and Technology Research Partnership for Sustainable Development) projects for FY2018 including a collaborative research program between the Institute of Ocean Energy, Saga and Universiti Teknologi Malaysia.

SatrepsThe collaborative research is entitled “Project for Development of Advanced Hybrid Ocean Thermal Energy Conversion (OTEC) Technology for Low Carbon Society and Sustainable Energy System: First Experimental OTEC Plant of Malaysia.”

This study is aimed at… Continue reading
