“…The third area of research, usually in conjunction with one of the first two, is to analyze the economic feasibility, or at least, the system costs of OTEC, desalination, and accompanying SWAC outputs. Sections 2.2 and 3.3 explore these aspects in more detail, highlighting the main economic considerations where the emphasis is placed on the economics of both OC-and CC-OTEC, showing that costs decrease when moving to the CC-OTEC technology, due in part to the overall larger size (>10 MW) of these systems compared to smaller OC-OTEC plants [6,8,10,29,40,41].…”

“…Previous low-resolution mapping of potential OTEC resources that looked at sites with a temperature difference~20 • C and within 200 miles of coastlines [15] is expanded upon in the present work. Suitable locations within the Caribbean region, with an emphasis on SWAC, have also been previously investigated [40]. A very recent report explored a specific site in Puerto Rico in great detail, and represents the follow-up stage for any given sites identified here [42].…”

Ocean Thermal Energy Conversion—Flexible Enabling Technology for Variable Renewable Energy Integration in the Caribbean

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.

“…Energy inefficiency of building systems and technologies The demand for cooling is increasing steadily in hot tropical climate, the total energy consumed by air conditioning and ventilation can exceed 50% of total energy consumption in a building. (Hunt, Byers, & Sanchez, 2018) Building system that relies on fossil fuels has caused more greenhouse gases (GHG) emission, urban heat island (UHI) phenomenon locally and global warming in world. (Santillán-Soto, García-Cueto, Lambert-Arista, Ojeda-Benítez, & Cruz-Sotelo, 2019) 3.…”

Seawater is deemed as renewable energy and supplemental water source in coastal development. Utilizing seawater resources in air conditioning and plumbing system involves implementation of innovative technology such as seawater air conditioning (SWAC), seawater heat pump (SWHP), landscape irrigation system, potable water and greywater recycling. The research aims to demonstrate seawater usage as water efficiency option to reduce energy consumption, save freshwater and environment. The research had adopted systematic literature review (SLR) method to analyze the application of seawater building air conditioning and plumbing system on current publications and papers, and conclude with summary of benefits and challenges.
