Thermodynamic Analysis of a Closed-Cycle Ocean Thermal Energy Conversion Power Plant for Offshore Platforms

Abstract

he world is currently facing two major challenges: global climate change and sustainable development. Efforts to generate electricity from renewable energy sources continue steadily. In this study, a closed-cycle ocean thermal energy conversion (OTEC) power plant with various working fluids with zero Ozone Depletion Potential (ODP) and per unit mass flow rate for offshore platforms is designed and thermodynamically analyzed using Engineering Equation Solver (EES). The calculated results shows that ammonia (R-717) has the highest electrical performance of 45.51 kW per unit mass flow rate among the studied working fluids for OTEC.
