This article describes research being conducted in southeast Florida waters to create blue energy and harness the ocean's power.
There are many considerations when developing blue energy. For example, the farther you are from the equator, the higher the tides are: 3 feet in Florida, 30 feet in Maine. Additionally, to be a viable energy source, renewable energy needs to be harvested fairly close to where it will be used by a human population.
Ocean thermal energy is conceptually quite simple, because it works just like traditional electrical power plants.The high-pressure steam is used to turn a turbine and a generator, and electricity is produced. So the temperature difference between the ocean surface and the deep water becomes a source of blue energy — ocean thermal energy.What is less well understood is the variability of the speed and position of the Florida high-speed core. Because such variability is of great interest to the ocean energy community, SNMREC has undertaken an observational program using long-term deployments of acoustic current profilers.
At oceanic temperatures, ammonia/water mixtures can be used as the working fluid, provided a surface-water/deep-water temperature difference of ~20°C is available. Because the Florida Current provides a steady source of warm, tropical water into the Florida Straits, and because the bottom water in the Straits remains much colder, there is ocean thermal energy conversion potential offshore of southeast Florida.
Multibeam mapping uses sand to measure a “swath” of ocean bottom. This is followed by underwater robots who reproduce the same data with the base map. Then a habitat map is drawn to see if organisms or the seafloor would be damaged.Perhaps nowhere is the notion of interactions embodied more than in the case of open-ocean current generating systems and the physical environment, especially when commercial-scale deployments are considered.
