Ocean Thermal Energy Conversion - Stanford University
WebThe OTEC potential in Malaysia using ocean conditions and bathymetry data has been previously studied and demonstrated. Following this, Ocean thermal energy conversion (OTEC) is a solution for environmental and climate change issues in the tropics. The OTEC potential in Malaysia using ocean conditions and bathymetry data has been previously ... WebDec 1, 2009 · Fig. 1 shows a schematic diagram of a simple OTEC power plant operating on a closed cycle. This system uses the warm surface seawater to evaporate a working fluid such as ammonia or Freon gas, which then drives a turbine. After passing through the turbine, the vapor is condensed in a heat exchanger that is cooled by cold deep seawater. WebMar 15, 2024 · This paper provides an overview of studies on closed thermodynamic cycles and the numerous difficulties that OTEC technology faces. A description of the thermodynamic cycles incorporating mixed or pure working fluids, as well as the implications of different working fluids on cycle efficiency were also studied. how to start code in python
