Ocean Thermal Energy Conversion (OTEC)

Ocean Thermal Energy Conversion (OTEC)

Dr. Andrea E. Copping

OTEC (Ocean Thermal Energy Conversion) is has the potential to provide baseload power to the grid by generating energy from the thermal differential from warm tropical surface waters and cold deep ocean water. OTEC technology is well understood but plants have not been deployed due to the high capital costs for onshore or floating offshore plants. With renewed concerns about climate change including sea level rise and ocean acidification, as well as OTEC’s potential to produce desalinated water, provide sea water air conditioning (SWAC), and other added value uses, many nations are taking a strong look at developing OTEC for carbon mitigation.

This workshop will review the existing OTEC technologies, discuss the potential environmental effects of this type of power generation, and examine potential additional uses of OTEC beyond power production. Join us to learn more about OTEC, to contribute your knowledge on the feasibility and value of OTEC, and to meet some of the practitioners working towards commercial scale OTEC.
