Global OTEC Resources, a business aspiring to bring a new form of renewable energy to tropical resorts, has released images of its first design concepts. The company has reached a cost model for harnessing the thermal energy stored in our oceans which is comparable to, if not cheaper than, the cost of running diesel generators.
According to the company, most of these resorts burn approximately 8.000 litres of diesel every day having negative effect on the oceans.

The technology is based on using the different temperatures between deep sea water and surface sea water. Specifically, the cold-water pipe returns seawater from a depth of 1,000m, achieving the temperature difference with the warm surface water of 20 degrees centigrade. Ammonia is repeatedly evaporated and condensed to power a turbine and produce electricity.
The turret and mooring system is designed primarily to allow the unit to align itself with incident weather conditions in order to withstand large wave heights and wind speeds, which is critical for many locations across the tropics, as the company noted.
Global OTEC Resource’s concept will deliver a net capacity of 1-MW of electricity to its customers across the tropics which is enough to fully power most small-to-midsized resorts or islands.
Finally, the company decided to focus its design on the needs of Small Island Developing States (SIDS) after learning that many small islands consume over 8.000 litres of diesel a day.
