Overview
First conceptualised in 1881, Ocean Thermal Energy Conversion (OTEC) remains one of the most underdeveloped renewable energy technologies despite it’s significant potential. This presentation will cover the inception of OTEC and the implementation in Cuba, the foundational works undertaken in the 1970s by the United States Department of Energy, and, current operating OTEC plants.
As with all renewable technologies, commercialisation of this technology remains the key to future development. OTEC will be compared to other competing renewable energy technologies looking at the gap that OTEC fills in the tropics, where wind and solar suffer limitations.
Join Sam Johnston, CTO of Global OTEC, as he discusses the technical and engineering challenges facing OTEC development and the progress made in recent years; synergistic industries both onshore and offshore; and the future of OTEC technology.
