Ocean Thermal Energy Conversion (OTEC) is one of the few renewable energy technologies that can provide an unlimited source of continuous, electric power. Sea Solar Power (SSP) is currently involved in a coordinated design and commercial development effort that will bring their patented SSP OTEC cycle to commercial operation in 2007. The SSP OTEC cycle not only provides continuous electric power, but also provides large quantities of desalinated water, which is even more valuable than electricity in many countries and islands. The first 10 MW land-based SSP plant is now being developed for application on an island in the Caribbean. (Negotiations are ongoing, so the location cannot be disclosed at this time, but will be disclosed when the paper is delivered at the conference.) This paper will review the on-going efforts that will bring this technology to commercial operation and the potential benefits of this technology. The technology is based on a proprietary binary Rakine thermodynamic cycle that utilizes the temperature difference between warm surface water and cold deep sea water. These temperature differentials are unique to the Tropics. The 10 MW landbased SSP plant will also provide 11,355 cubic meters-per-day (3 million gallons-per-day) of desalinated water. Another beneficial byproduct of this technology is the ability to support mariculture, or fish-farming, using the nutrient-rich deep seawater. Mariculture can provide food for thousands of people and enhance the economy of the host country, as an export commodity. R. W. Beck is supporting the design of the standard, 10 MW land-based plant for this application and is also supporting the commercial development activities of SSP.

Many Caribbean island nations have historically been heavily dependent on imported fossil fuels for both power and transportation, while at the same time being at an enhanced risk from the impacts of climate change, although their emissions represent a very tiny fraction of the global total responsible for climate change. Small island developing states (SIDSs) are among the leaders in advocating for the ambitious 1.5 °C Paris Agreement target and the transition to 100% sustainable, renewable energy systems. In this work, three central results are presented. First, through GIS mapping of all Caribbean islands, the potential for near-coastal deep-water as a resource for ocean thermal energy conversion (OTEC) is shown, and these results are coupled with an estimate of the countries for which OTEC would be most advantageous due to a lack of other dispatchable renewable power options. Secondly, hourly data have been utilized to explicitly show the trade-offs between battery storage needs and dispatchable renewable sources such as OTEC in 100% renewable electricity systems, both in technological and economic terms. Finally, the utility of near-shore, open-cycle OTEC with accompanying desalination is shown to enable a higher penetration of renewable energy and lead to lower system levelized costs than those of a conventional fossil fuel system.

The Malaysian Government has set a target of achieving 20% penetration of Renewable Energy (RE) in the energy mix spectrum by 2025. In order to get closer to the target, Ocean Thermal Energy Conversion (OTEC) aligned with solar PV, biogas and biomass energy sources must be evaluated and comprehended. Hybrid OTEC systems consisting of energy and water production are currently under research and validation. Therefore, for the construction of a commercial OTEC plant, 1 MW or 2.5 MW, the choice of a strategic location or potential site is vital. In this paper, oceanographic data such as seawater temperature, depth, salinity and dissolved oxygen obtained from the Japan Oceanographic Data Center (JODC) for Semporna, Tawau, Kudat, Pulau Layang-Layang and Pulau Kalumpang in Sabah, Malaysia, are reported. The RE available from the Exclusive Economic Zone (EEZ) on the coast of Sabah was estimated based on the JODC data obtained. There were no remarkable differences in temperatures between the five sites, which were reported as approximately 27 °C at the surface and 7 °C at depths below 600 m. The surface salinities below 100 m at those sites were slightly lower than the deeper waters, where the salinity increased up to approximately 34.5 PSU. Dissolved oxygen data from the Pulau Kalumpang site showed a slight increment to approximately 4.7 mL/L at depth intervals below 50 m, before declining steadily to approximately 1.7 mL/L along with the depth. The temperature-salinity profiles of the Malaysian sites were congruent with those of Palau, Kumejima and Okinawa, but not with that of Fiji, where the salinity profile showed a distinct variation at the relative depth (below 200 m). Estimates of RE using two different methods were used to prove the potential of OTEC in Malaysia.
