Cycle 2 (2012 Deadline)
Temperature profile of the ocean seabed from the city of Puerto Plata, Dominican Republic, and preliminary design for a commercial exploitation of cold water to supply for a central air conditioning system
PI: Eduardo David Sagredo Robles (Universidad Tecnologica Santiago)
U.S. Partner: Naphtali David Rishe (Florida International University)
Project Dates: August 2013 to July 2016
Electricity shortages represent one of the major problems facing the Dominican Republic. For more than 50 years, the country has experienced daily electric power blackouts lasting some four to five hours. The cost of electricity in the Dominican Republic is more than 2.5 times the average cost worldwide, which causes financial hardships not only for the general public but also for operators of the large hotels that contribute substantially to the country's economy. Air conditioning uses approximately 60% of the electricity consumed in tourist areas of the Dominican. Given the high cost of electricity and frequent power outages, implementation of a reliable, renewable, and nonpolluting energy source that can supply air conditioning to these hotels would represent the difference between economic survival versus bankruptcy, with its associated severe impacts on local employment.
This PEER Science project is designed to develop a model for how such an energy system could be designed and implemented. Dr. Sagredo and his team will place remote sensors at regular intervals along the sea bed to gather data to create an Ocean Temperature Profile from the city of Puerto Plata extending eight miles north until a depth of 1,000 meters is reached. The data collected will provide input to the design of a pipe along the sea floor that would extract the cold bearing water to the surface at Puerto Plata to provide a cold-water supply for air conditioning. Besides designing the pipe, the researchers will also study potential environmental impacts of their system, as well as optimization of the energy that would be needed to pump the seawater. Once their designs and models are complete, they will share their findings with local stakeholders, including hotel operators and entrepreneurs who might be interested in supporting implementation of the system after the PEER Science project is complete.
